A separate file named pub/IABmins.jan91Arch.txt summarizes a day-long discussion of the future of the Internet architecture by the IAB and IESG. STANDARDS ACTIONS: 1. OSPF Following IESG recommendation, the IAB has approved Draft Standard state for the OSPF interior gateway protocol. The IETF has accumulated and documented significant field experience with multiple implementations of this protocol. The extensive documents describing operational deployment of OSPF and analyzing the protocol will be published as informational RFCs. The IAB notes that this advance is part of the normal evolution of a new protocol, and does not constitute a recommendation or requirement. The issue of which IGP should be selected as the "common" IGP will be taken up by the July IETF meeting in Atlanta, GA. 2. IPX over IP Following IESG recommedation, the IAB has approved Proposed Standard state for a specification for the encapsulation within IP of the Novell protocol suite IPX. The IAB notes that this does not constitute any endorsement of IPX, nor is IPX itself being considered for Internet standardization. Although we would prefer commonality and interoperability in all protocol layers, standardization of encapsulation of other protocol suites in IP is desirable and useful to the community. 3. Other The IAB has taken the following additional standards actions since April 1991, following IESG recommendations: o Proposed Standard state for the OSPF MIB. o Proposed Standard state for Interface Extension MIB [RFC-1229]. Westine [Page 3] Internet Monthly Report May 1991 o Proposed Standard state for AppleTalk MIB. 4. Summary of RFCs The editorial process for RFC publication generally follows approval by the IAB, so we cannot generally give an RFC number when an IAB action is announced. The following list shows the RFC numbers for the specification documents resulting from IAB actions since January 1991. * IP-over-ARCNET to Proposed Standard state: RFC-1201. * IP-over-SMDS to Proposed Standard state: RFC-1209. * Concise MIB definitions to Proposed Standard state: RFC-1212. * (SNMP) MIB II to Draft Standard state: RFC-1213. * OSI Internet Management MIB II to Proposed Standard state: RFC-1214. * PPP Extension to Bridging to Proposed Standard state: RFC-1220. * POP3 to Draft Standard state: RFC-1225. * 802.4 Token Bus MIB to Proposed Standard state: RFC-1230. * 802.5 Token Ring MIB to Proposed Standard state: RFC-1231. * DS1 MIB to Proposed Standard state: RFC-1232. * DS3 MIB to Proposed Standard state: RFC-1233. * OSI CLTS over UDP to Proposed Standard state: pending. Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- No progress to report this month. Deborah Estrin (Estrin@USC.EDU) Westine [Page 4] Internet Monthly Report May 1991 END-TO-END SERVICES ------------------- No progress to report this month. Bob Braden (Braden@ISI.EDU) INTERNET ENGINEERING REPORTS ---------------------------- No progress to report this month. Phill Gross (pgross@NIS.ANY.NET) Westine [Page 5] Internet Monthly Report May 1991 INTERNET PROJECTS ----------------- BARRNET ------- Three new connections were added in May, including one T1, one 56kbps, and one dial-in, bringing the total number of connected members to 87. One 9600 bps dial-in was converted to a dedicated line. Four new members were approved, including Santa Clara University and St. Mary's College, with the connections to be completed in the coming month or two. A T1 line was installed between Stanford University and the Naval Postgraduate School in Monterey, which will give high-speed connectivity to sites in the Monterey area when it is activated in June. Paul Baer (baer@jessica.stanford.edu) BOLT BERANEK AND NEWMAN INC. ---------------------------- Inter-Domain Policy Routing During the month of May we have been working on producing two Internet drafts: one detailing how to configure an administrative domain for inter-domain policy routing and one describing policy- based resource allocation. A draft of the configuration document will be circulated to the IDPR working group for review during June. Terrestrial Wideband Network (TWBNet) and ST/IP Gateway Videoconferencing and Simulation On May 24, a new release of WPS software was installed. The principal feature of this version is the addition of "streams" (trunk-line bandwidth reservation). Stream service is useful when bandwidth requirements are known in advance, and when service guarantees are needed. By reserving appropriate resources for an application, the network can meet the application's bandwidth and delay requirements even in the face of other demands. In this way, streams allow the TWBNET to support real-time applications such as conferencing and SIMNET exercises, without letting other traffic negatively impact them. The other major new feature is the switch to HAP version 1 (RFC 1221), with backward-compatibility support for HAP version 0. The new version of HAP contains a "protocol identifier" field, so that ISO protocols (e.g., CLNP) as well as Internet protocols (IP, ST, GG) may be used above HAP. Westine [Page 6] Internet Monthly Report May 1991 During May, conferencing facilities were installed at Los Alamos National Laboratories (LANL). LANL was the first TWB site to use the BBN T/20 IP gateway and the Picturetel System 4000 Codec. The German site was restored to operation this month, following a move which took it off the network temporarily. There are now eight conferencing sites -- UCL, BBN, RIACS, ISI, DARPA, Germany, RADC, and LANL. These sites participated in a total of 15 video conferences and demonstrations. Of these, two included four sites, five included three, and the remaining eight were point to point. Conferences were held for discussions in the following areas: the Security Research Group, the IETF Router Requirements Working Group, the ALSP project, the London Unix Users Group, LANL Internetworking projects, Rome Labs multimedia demonstrations, and the UK Fat-pipe Operational Management Group. The TWBNet was also used to support three one-day Simnet exercises between Fort Knox and Fort Rucker. DARPA Internet / ICBnet Infrastructure Operations and Maintenance We continue closely monitoring the US-UK FatPipe for any recurrence of trouble with either the link or the routers. During May the BBN monitor was able to reach the ULCC router on the Fat Pipe for 44,426 of 44,640 total minutes. This corresponds to a 95.8% uptime from BBN to ULCC. We are planning installation of T/20 routers on the US-UK FatPipe at the end of June. Installation of T/20 routers on a satellite link from BBN to WPC has been successfully routing IP and ST traffic since mid-May. The ICB met at The Hague this month. Three BBNers attended. T/20 routers are slated for installation in ICBnet at RSRE and STC this summer. The difficulty with fragmentation reassembly timeouts in the Butterfly software has become more severe at the FIX East and FIX West routers. This problem results in loss of EGP updates and timing out of routes at the FIXes. A T/20 router is slated to replace the FIX East Butterfly, attached to the US end of the US-UK FatPipe, but a better interim solution is still needed for the Butterflys. This problem has been escalated to a higher priority for resolution and a temporary "fix" has been installed. Westine [Page 7] Internet Monthly Report May 1991 On May 10th the ICBnet Operations Management Group met via video conference. There were representitives from BBN, ULCC, Darpa, NRI and NASA participating. The next OMG meeting is scheduled for Tuesday June 18th. Jil Westcott (westcott@bbn.com) CICNET ------- The National Science Foundation renewed it's grant to CICNet for 1991-1992. This funding is used to fund the CICNet Network Operations Center and other services for members. Three new members joined CICNet during March and April: - Concordia College, River Forest, Illinois - Notis Systems, Evanston, Illinois - The Field Museum of Natural History, Chicago, Illinois The Concordia connection should be up in June; Notis and the Field Museum will follow later this Summer. All three will be 56kb connections. CICNet President E. Michael Staman attended the April FARNET meeting in Austin, Texas. Assistant Director John Hankins gave a presentation on the regional networks to the conference on Advanced Computing and Information Technologies for the Social Sciences, which was held in Athens, GA on April 8th and 9th. Hankins also talked about regional networks at the Merit Networking Seminar held in Ann Arbor on May 20 and 21st. Michael Staman and Kimberly Shaffer of CICNet also participated in the seminar. J. Paul Holbrook (holbrook@cic.net) CORNELL ------- The UMd implementation of OSPF has been merged into gated. Basic testing was performed although routes were only installed from OSPF into gated and policy was not yet implemented. A first pass of full exchange of routing information has been implemented but not tested. Westine [Page 8] Internet Monthly Report May 1991 Two people will be attending the OSPF interoperability testing at FTP Software in Wakefield, Mass during the first week of June. The merge is still rough and much work still needs to be done to smooth it out, but an alpha release may be available before the end of June. Work is also progressing on merging the BSD 4.3 Reno radix tree based routing table into gated. A version is expected to be working by the middle of June, but probably will not be available with the OSPF alpha release. Jeffrey C. Honig (jch@mitchell.cit.cornell.edu) EDUCOM NATIONAL NETWORK ----------------------- A minor milestone in high-speed, long-haul networking happened at the recent Educom National Net '91 conference in Washington, DC: TCP transfers from a Cray YMP at Pittsburgh Supercomputer Center to a Sun Sparcstation-2 on the show floor ran at a sustained rate of 10Mb/s (by `sustained' I mean sustained over hundreds of megabytes of data transferred -- In one of the first tests, we shipped 256MB from the PSC to DC in 3.9 minutes). The rough topology was: FDDI T3 backbone Ethernet 100Mb/s 45Mb/s 10Mb/s PSC YMP -------> PSC ENSS --....--> DC ENSS ---------> SS-2 The limiting bandwidth was the show ethernet & we ran at that bandwidth. If we could have gotten in & out of the ENSS at >= 45Mb/s, we would have run at the 45Mb/s NSFNet backbone bandwidth. (Dave Borman's Cray TCP has been measured at over 300Mb/s. My TCP on the SS-2 runs 48Mb/s through the loopback interface (i.e., copying all the data twice, doing both sides of the protocol & context switching on every packet) and should easily sink or source >100Mb/s as soon as Sun comes up with a decent high-speed network interface.) The real milestone is that two completely independent implementations of the RFC1072/RFC1185 "fat pipe" extensions, one by Dave Borman of Cray Research for Unicos on the YMP & one by me for an experimental TCP/IP running on the SS-2, interoperated with no problems. [This gave me no small measure of joy: Sun demonstrated their normal inability to supply system source to academic sites & I didn't get a copy of 4.1.1 (the only version of Sun OS that would run on a SS-2) until Friday of the week before the show. I spent a very long weekend throwing out Sun's network & Westine [Page 9] Internet Monthly Report May 1991 IPC code & replacing it with my experimental 4.4BSD stuff and got a working kernel 45 minutes before the movers came to crate up our lone Sparcstation-2 & ship it from California to DC. So the very first chance to test my RFC1072 implementation against Dave Borman's was when we got the machine uncrated & connected the SS-2 to the show net in DC. I was all resigned to another 36 hours of sleepless debugging when, to my utter astonishment, the Cray & Sparcstation flawlessly negotiated a 512KB window & timestamps, then happily started exchanging data at a very high rate. (Several other groups were busy setting up their demos. I started up my usual throughput test programs on the Cray & Sun then looked down at the "recv" indicator light on the Cabletron transceiver & noticed it was on solid -- I stared at it for at least 30 seconds & it didn't even blink. Right after that I heard one of the Cornell people say "What happened to the network? Our connection seems to have stopped." and I did my best to look innocent while the test finished.)] The big disappointment was that I was worried about what would happen when the TCP congestion avoidance / recovery algorithms started interacting with half a megabyte of stored energy (in- transit data) in the pipe. So I'd spend a bunch of time tuning the Fast Retransmit and Fast Recovery algorithms & had a bunch of instrumentation set up to watch how they'd perform. But the damn T3 NSFNet refused to drop packets -- we shipped slightly more than 30GB (roughly 22 million data packets) during the three days of the show & the kernel network stats said that 6 were dropped. Naturally, I wasn't watching for any of these 6 & a 0.00003% loss rate wasn't enough test any of the spiffy new algorithms. Oh well, maybe next time I'll bring my wire cutters and chop halfway through the cable to make things a bit more interesting. [The one interesting piece of behavior had to do with the ethernet controller on the Sun: The LANCE is a half-duplex device so if it's receiving back-to-back ethernet packets it will never attempt to transmit, even if it has data available to send. TCP will attempt to ack every other packet but, since new data packets were arriving back-to-back from the ENSS, the ack packets just got queued in the LANCE on the SS-2. Since the acks can't get out, eventually (after half a megabyte is sent) the window on the Cray should close, it should stop sending packets & the SS-2 should get to dump 180 back-to-back ack packets, re-opening the window & restarting the data flow. This would have resulted in essentially the stop-and- wait performance of a BLAST protocol but, fortunately, there seems to be a 128KB buffer somewhere in the T3 NSFNet so after 90 data packets there was a 30us pause, allowing the SS-2 LANCE to grab the ethernet, dump 45 back-to-back acks, then start collecting the next 90 data packets. So the window on the Cray never shut & the pipe Westine [Page 10] Internet Monthly Report May 1991 stayed full -- due to essentially an engineering mistake in the network (a transcontinental T3 run at T3 needs at least half a meg of buffer everywhere a queue can form). This, incidentally, is one reason why we used a half megabyte window instead of the 80KB window required to fill a 36ms RTT into 10Mb bandwidth-delay product.] Anyway, I'm writing this mostly to document that it happened & to thank all the people at LBL, PSC, Merit, Cray & Sun that made it happen. I'm particularly grateful to Dave Borman for some great Cray TCP software and to Geoff Baehr at Sun for battling with the lawyers and getting us the system pieces we needed (it's nice to know that at least part of Sun still ranks engineering over bean counting). And I am eternally grateful to Wendy Huntoon of PSC & Elise Gerich of Merit who put in long, long hours to get the new and almost untested PSC & NSF T3 connections up & running, then kept everything running smoothly and essentially trouble free for the entire show. Van Jacobson (van@ee.lbl.gov) FEDERATION OF AMERICAN RESEARCH NETWORKS (FARNET) ------------------------------------------------- FARNET held a plenary meeting April 30-May 1 in Austin, Texas, hosted by the University of Texas. In addition to the FARNET members, fifteen educators from the pre-college and special education community were present to describe educational applications using the Internet. These ranged from international studies of global change to a multi-school contest to determine the most efficient way to make 1,000 egg rolls. The educators were excited to discover one another, and the FARNET members were excited about extending service to more school districts. FARNET has formed a K-12 working group to continue activities in this area. FARNET has received funding to pursue several programmatic goals in the coming year, from the National Science Foundation and Advanced Networks & Services, Inc. The goals include improving end-user services in the Internet, coordinating and advancing K-12 activities, and collecting and disseminating information about the use of the Internet to a broad audience. These programs will be conducted in cooperation with other organizations to maximize efficiency; if your organizaiton is interested in cooperating, please contact breeden@farnet.org. Laura Breeden accepted a position as Executive Director of FARNET, effective May 28. She was formerly with BBN, where she was manager Westine [Page 11] Internet Monthly Report May 1991 of the network services group. She will be setting up offices for FARNET in the Boston area. Through NYSERNet, Inc., FARNET has received an NSF grant to hold a workshop to articulate the position of the mid-level networks on the funding and management of the NSFNET backbone after the current agreement with MERIT, Inc. expires in November 1992. This workshop will be held in August; results will be made public in September, upon completion of the final report to NSF. FARNET representatives attended the joint RARE/EARN conference in Blois, France in May. Reports of that meeting will be available later this summer. Laura Breeden (breeden@farnet.org) ISI --- GIGABIT NETWORKING Greg Finn wrote a paper that describes the use of single chip point-to-point transmit technology to create a LAN and then to use that LAN internally within an architecture to eliminate communications bottlenecks. Essentially, the capacity of a point- to-point technology scales with the number of attached nodes. This becomes attractive when considering emerging transfer intensive applications such as video conferencing, multimedia and distributed computing.

Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING The SPARCstation version of the Voice Terminal (VT) program, the packet audio component of our teleconferencing system, is now working successfully with ST-II, as well as with UDP plus IP multicasting. This is a result of tests conducted this month with BBN to debug both VT and BBN's socket-based ST-II (RFC 1190) implementation for the SunOS kernel. We went through several iterations of building kernels with ST-II modules provided by BBN combined with Van Jacobson's DARTnet router modules. In a large- scale experiment on DARTnet, we ran the ST kernel on all the DARTnet routers and ran VT at all seven leaf nodes; ISI and BBN communicated with live voice data while the other sites competed with continuous traffic generated automatically by VT. Steve Casner, Annette DeSchon, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, schooler@ISI.EDU) Westine [Page 13] Internet Monthly Report May 1991 JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK --------------------------------------------- General information is available on-line from nisc.jvnc.net. Use "telnet nisc.jvnc.net", username "nicol" and no password. Network availability as of Wednesday, May 22 is 99.9% and it reflects the highest uptime within the past six-month interval (Dec. 1990 to May 1991). The average for this same statistical interval is 99.66%. The traffic for April was 3,657,230,449 (total in plus out packets) and this number represents an increase of 7.04% over March. An additional Dialin'Tiger backbone node was installed in Newark, NJ. Other Dialin'Tiger backbone nodes include Princeton, NJ; Trenton, NJ; New York, NY; and New Haven, CT. Installation of the cisco CSC-3 processors for the backbone upgrade is in progress. Terminal servers were installed in the backbone nodes for added dial-in out-of-band diagnostics. Introduction to Data Networking and TCP/IP, the first in a series of JvNCnet Symposiums, took place on Friday, May 17,1991 at Princeton University. The symposium was aimed at network operations and technical staff of local area networks. This course was designed as an entry level introduction to TCP/IP networking and how the operations of a network are performed. Each participant received Douglas Comer's Internetworking with TCP/IP, Vol. 1, Second Edition plus selected rfc's (for novice and experienced Internet users) and articles addressing networking issues such as LANs. The course consisted of the following subjects: WHAT IS A NETWORK? LAN and WAN defined Member and JvNCnet roles. WHAT MAKES A NETWORK? What are a host, terminal server, router, CSU/DSU? What is the function of the telephone company? What are an ENS, a POP, a BNS? TCP/IP Standard protocol, IP address, packet building and transport, hops. What to do when something goes wrong. ISO and its seven layers Basic troubleshooting, the BNS, Telnet, rlogin, ftp Westine [Page 14] Internet Monthly Report May 1991 Part of the afternoon was spent in explaining how the functions of operations, installation and maintenance, engineering, and information services as a whole positively impact data networking at JvNCnet. Operation's specialized tools and standardized procedures used to maintain network performance were identified and described. Installation & Maintenance explained the use of conducting site surveys, performing new node installation, field upgrades, site support, preventative maintenance and procedures of handling defective equipment. The engineering discussion centered on maintaining all software systems as well as maintenance, development, implementation, and analysis of network performance. IS concentrated on the function its supports: Liaison to JvNCnet members, Internet administrator and resource information provider. IS also maintains specific databases and publishes the Megabytes newsletter. The symposium was a great success with respect to the number of participants and their feedback of the course. Future symposiums will be scheduled soon. For further symposium program information, please send email to "nisc@jvnc.net. The next JvNCnet Regional Meeting will be held on Friday, June 28, 1991 at the Computer Science Building, CS Bowl 104, Olden and William Streets, Princeton University. Information regarding this meeting is in development and will be available shortly. Rochelle Hammer (hammer@nisc.jvnc.net) LOS NETTOS ---------- Walt Prue attended the Cisco sponsored Networkers '91 event in San Francisco, May 28-31. Walt Prue (Prue@ISI.EDU) MERIT/MICHNET ------------- Several MichNet staff members spent time at the end of May helping with the Merit Networking Seminar, a two-day conference about the Internet which was sponsored by the Merit/NSFNET project and held Westine [Page 15] Internet Monthly Report May 1991 in Ann Arbor. Along with assisting with audio-visual materials and technical aspects of the conference, MichNet staff members met with conference attendees from member organizations, and talked to attendees from K-12 schools and potential affiliates about MichNet and it's capabilities. Al Rogers of the FrEdMail (Free Educational Mail) Foundation, in Ann Arbor for the Merit Networking Seminars, spent time with the Merit Engineering staff getting a FrEdMail gateway working between FrEdMail and MichNet. Like the previous gateway at CERFNET, this will allow interchange between FrEdMail and the Internet, and better access for educators throughout Michigan. Because of MichNet's connection to SprintNet and Autonet, users all over Michigan and the rest of the United States can have dialup access to the Internet by calling into one of these networks and then telnetting from the "Which Host?" prompt. Users will need to have an authorization account, available from MichNet or several of our member universities. Authorization service accounts cost $40 to set up and $35 per month to maintain, plus the applicable network charges. For more information contact: acctmgr@merit.edu (for authorization service accounts) info@merit.edu (for general information) Saginaw Valley State University became a Merit member in April, after having been an affiliate for some time. As part of this change, we are able to provide public dialin in the Saginaw/Bay City area. W. Scott Gerstenberger, Merit Associate Director, chaired a panel session at the SIGUCCS management conference in April. The session was entitled "Campus Internetworking Issues - Moving Into a National Networking Environment". The other panel members were Jane Caviness (NSF), Tom Gabriele (Western Michigan University), and Mike Dorl (UW-Madison). Eric Aupperle, president of Merit, participated in a session at the Advanced Computing and Information Technologies for the Social Sciences second annnual meeting. The conference was held 8-10 April at the Univ. of Georgia, and Aupperle presented a talk entitled "National Networks," which described Merit's NSFNET activities. Pat McGregor (patmcg@merit.edu) Westine [Page 16] Internet Monthly Report May 1991 NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NEARnet has grown to 75 members. During the month of May, NEARnet transitioned to the T3 Network, the MERIT Computer Network is providing T1 backup service through the NSFnet node in New Jersey. NEARnet has established a T1 connection with Alternet under a cooperative agreement with UUNET. Users will have expanded access to the organizations on both networks. NEARnet has implemented an automated phone answering system to handle calls made to the NEARnet hotline. Over 160 people attended the fourth semi-annual NEARnet Technical and User Seminar on Friday, May 3, 1991. The seminar was held at the Gutman Library at the Harvard Graduate School of Education, in Cambridge, Massachusetts. Jim Luckett, the executive director and vice president of NYSERNET spoke about the new and exciting programs which his regional network is initiating. The technical session of the seminar consisted of an overview of Usenet news administration by Rich Salz of BBN. John Curran of the NEARnet staff also spoke on the subject of LAN/WAN troubleshooting. The user session consisted of several demonstrations of network applications including an introduction to the capabilities and resources available over the Internet by John Rugo of the NEARnet Staff. Raghu Reddy of the Pittsburgh Supercomputing Center, demonstrated the use of a performance measurement tool called perfview, a program written at PSC that is useful for scientists in previewing animations before putting them on tape. Joe Blackmon of the National Center for Supercomputing Applications, presented a demonstration of visualization software tools developed at NCSA and a video tape of a computer-generated model of a severe thunderstorm. There was also a demonstration of the Polygen/IBM QUANTA molecular modeling software package present by Dr. Chris Ruggles of the Polygen Corporation, and a BBN/Slate demonstration by Terry Crowley of BBN. John Rugo (jrugo@bbn.com) Westine [Page 17] Internet Monthly Report May 1991 NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Corinne Carroll attended the MERIT Networking Seminar in Ann Arbor, Michigan. The NNSC distributed additions to chapters 3 and 5 of the Internet Resource guide. Corinne Carroll (ccarroll@nnsc.nsf.net) NSF BACKBONE (Merit) ------------------- Inbound traffic on the NSFNET T1 infrastructure as measured in packets totaled 7,564,149,615 packets during the month of May 1991. This is an increase of .263% over April's inbound traffic of 7,544,331,873 packets. As of the end of May, 2763 networks are announced to the T1 infrastructure, with 882 registered foreign nets as part of this total. Nets passing traffic over the NSFNET T3 infrastructure continue to increase, numbering 445 at the end of May. Inbound packet traffic on the NSFNET T3 infrastructure had a lower bound of 1,342,479,220 packets measured; technical difficulties resulted in the complete loss of traffic data for four days on all nodes. Currently, a single point of interconnection located at Ann Arbor exists between the T1 and T3 networks. A second interconnection point is being completed at San Diego, with implementation in June. NCSA, SDSC and Merit are conducting studies to evaluate Cray to Cray performance over the T3 infrastructure. Questions being addressed include the degree to which application performance is enhanced by T3. NSFNET is soliciting regional and national networks to participate in an OSI demonstration for InterOp '91. Participating networks must provide a host with OSI applications running over a stack using CLNP at the network layer, a network pathway from the host to a router located on a shared network with an NSFNET NSS which supports passing CLNP packets, and a router on the shared network with an NSFNET NSS which supports CLNP and ES-IS. Regional and national networks currently passing CLNP traffic across the NSFNET are encouraged to join the demonstration. Further information is available from Sue Hares (skh@merit.edu) of Merit/NSFNET Internet Engineering. Guests at the Merit Network Operations Center included Han Keun Hee of the Systems Engineering Research Institute, Korea Institute of Science and Technology, and Han Ku Kim, Computer & Systems Westine [Page 18] Internet Monthly Report May 1991 Business, SAMSUNG Electronics. Both Hee and Kim are involved in building a national Korean network and had particular interest in the management and operation of the NSFNET. Representatives from the Defense Communication Agency met with Merit/NSFNET Internet Engineering and NOC personnel to discuss experiences with BGP and NOC tools, as they look to upgrade the current MILNET. Elise Gerich, of Merit/NSFNET Internet Engineering, was the representative of the NSFNET and North America to the RARE Networking Conference in Blois, France. Gerich presented two papers to the conference, "Management and Operation of the NSFNET Backbone" and "Expanding the Internet to a Global Environment but. . .How to Get Connected?" Gerich also attended meetings of the CCIRN and IEPG in Paris on behalf of the NSFNET and North American networking community. The Merit Networking Seminar held May 20 and 21 in Ann Arbor, MI was well received by 79 attendees. Speakers included Paul Evan Peters, Director of the Coalition for Networked Information (CNI); Jim Knighton, Jet Propulsion Laboratory, NASA; Carol Parkhurst, ALA-LITA, University of Nevada; Al Rogers, Executive Director, FrEdMail Foundation; John Hankins, CICNet; Dana Sitzler, MichNet; Dan Van Belleghem, NSF; Mike Roberts, EDUCOM; and Douglas Van Houweling, Vice Provost Information Technology Division, University of Michigan.

Jo Ann Ward (jward@merit.edu) NDRE and NTA-RD --------------- For information, there is currently being established a 34 Mbit/sec research network in Norway as an extension to the existing UNINET. Both NDRE and NTA-RD will probably by connnected to this new network. Anton Leere (leere@ndre.no) PREPNET ------- During May, three colleges joined PREPnet. Gettysburg College and Dickinson College will both be connected to the Harrisburg at 56Kbps, and Muhlenberg College will be connected to the Allentown hub, also at 56Kbps. PREPnet NIC (prepnet+@andrew.cmu.edu) Westine [Page 19] Internet Monthly Report May 1991 SAIC ---- This is SAIC's first contribution to the Internet Monthly Report. This networking group has participated in Internet activities since 1982 when it was owned by Linkabit. It changed hands to M/A-COM, and is now part of SAIC. Previous development work has included EGP, DGP (the Dissimilar Gateway Protocol) and now IDPR (Inter- Domain Policy Sensitive Routing). April Activities (withheld from last month's report by mistake): Testing of the IDPR prototype has continued through April. SAIC has obtained varying results of performance tests from the work done by USC. Our results show a larger drop in performance than was originally reported in USCs testing. Part of this performance drop appears to be related to the platform on which the encapsulation protocol is running and some local configuration differences. Further performance testing will be done when version 2 of the prototype is completed. During April, a graphic interface was developed at SAIC to aid in visualizing the operation of the IDPR protocol. Currently implemented features of the interface are a display of path setup activities, established paths, and path teardown activities. A display of virtual gateway status will be available soon. Work has begun on version 2 of the prototype as a first step to porting the software to gated. This effort requires 5 steps: 1. Combining the software modules implemented by BBN, SAIC, and USC into a single process to remove the inter-process communication overhead. 2. Port of the combined prototype to gated. 3. Provision of a configuration interface consistant with gated. 4. Reorganization of separate databases from the different functional modules into a single common database. 5. Upgrade of the protocol modules to conform to the most recent IDPR specification as much as practical. May Activities: A preliminary design for the port of the IDPR prototype software is nearly complete after a careful review of each of the modules. Westine [Page 20] Internet Monthly Report May 1991 In preparation for the demo, the monitor software was improved and made more flexible to handle different configurations. VG and PG summary status is now part of the display. A cross country demo with four sites -- Sparta and Mitre in McLean, BBN in Boston and USC -- was planned, but was thwarted by flaky network connectivity and some software bugs in the prototype uncovered by the more complex configuration. Despite this setback, a successful demo of the prototype and a networking tutorial were held at DCA using only the Mitre and Sparta facilities on June 4th. Planned activies: Work on an IDPR MIB will be starting soon. The MIB will not be implemented until the gated port is begun. Once the design for the software port is complete, we will begin re-coding the various modules. During June we hope to try the cross-country experiment once again.

Tracy LaQuey Parker (T.LaQuey@utexas.edu) UCL ---- John Crowcroft & Peter Kirstein attended the RARE European Networking Conference in Blois. They also attended the ICB meeting at TNO-FEL next to STC in the Hague. Upgrade plans for the ICB network in Europe and Canada were discussed at length. Wisespread deployed usagre of Slate for multimedia mail twixt ICB members is now effective. A video conference was held on the 30th between UCL and BBN to demonstrate to the London Unix User Group the feasibility of such technology. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- We have no significant events to declare this month. Dave Mills (Mills@UDEL.EDU) Westine [Page 22] Internet Monthly Report May 1991 DIRECTORY SERVICES ------------------ This section of the Internet Monthly is devoted to efforts working to develop directory services that are for, or effect, the Internet. We would like to encourage any organization with news about directory service activities to use this forum for publishing brief monthly news items. The current reporters list includes: o IETF OSIDS & DISI Working Groups o Field Operational X.500 Project - ISI - Merit - PSI - SRI o ISO/CCITT Directory Editing Meeting - synopsis o National Institute of Standards and Technology o North American Directory Forum o OSI Implementor's Workshop o PARADISE Project o PSI DARPA/NNT X.500 Project o PSI WHITE PAGES PILOT o Registration Authority Committee (ANSI USA RAC) o U.S. Department of State, Study Group D, MHS Management Domain subcommittee (SG-D MHS-MD) Steve Hotz (hotz@isi.edu) DS Report Coordinator IETF OSIDS & DISI WORKING GROUPS -------------------------------- Refer to IETF section (above) for additional information regarding the OSIDS and DISI working groups. Directory Information Services (pilot) Infra-structure WG --------------------------------------------------------- Ruth Lang (SRI) and Russ Wright (LBL) have finished the first round of surveys for their X.500 implementations guide for DISI. A second survey has gone out, and everything looks on track for a solid paper for the Atlanta IETF. Chris Weider (clw@merit.edu) Westine [Page 23] Internet Monthly Report May 1991 FOX -- FIELD OPERATIONAL X.500 PROJECT -------------------------------------- The FOX project is a DARPA and NSF funded effort to provide a basis for operational X.500 deployment in the NREN/Internet. This work is being carried out at Merit, NSYERNet/PSI, SRI and ISI. ISI is the main contractor and responsible for project oversight. ISI --- ISI organized the May 28 FOX phone conference, which included participants from all of the FOX contractors and NIST. The primary topic of this meeting was the status of projects ongoing at the various sites. Further discussion followed about establishing milestones for intra-FOX testing, demonstration, and eventual distribution of FOX sponsored projects. Other topics of discussion focused on potential Internet requirements for large distributed X.500 services, and the suitability of X.500 for bibliographic indexing applications. Steve Hotz (hotz@ISI.EDU) MERIT ----- This month Merit worked on representing "information resources" in an x.500 directory. This will include information about NICs, K-12 resources, and general online information. The UofM folks will start work to modify their MaX500 application to handle our object classes for these resources. We have been communicating with folks from Educom about the K-12 resources and with the NISI group about NIC information. An internet draft is in progress to document the resources schema definitions. Some specific activities related to the FOX project: we have been working to install some upgrades to quipu from Tim Howes, and have ordered a Sparc 2 to serve as another DSA for FOX activities. Chris Weider (clw@merit.edu) Mark Knopper (mak@merit.edu) Westine [Page 24] Internet Monthly Report May 1991 PSI --- An alpha-release version of an X.500-based tool to provide simple document retrieval capabilities on RFCs and FYI documents was completed, and has been made available to the participants of the FOX project. Wengyik Yeong (yeongw@psi.com) SRI --- SRI completed efforts to provide access to WHOIS information through the White Pages Pilot Project (o=Internet@ou=WHOIS). The Northern Swift Fox DSA offers Individual, Computer, Network, Domain, Autonomous System, Organization, and Group information. A request to add WHOIS schema extensions to the Cosine and Internet X.500 Schema will be made in June. Custos 0.1.1 (NIST) was retrieved and compiled. Testing has uncovered some ISODE version related problems: Custos has been developed and tested with ISODE 6.0 while SRI is running version 6.8. These problems are being addressed by NIST and SRI. Survey responses for the DISI X.500 implementation catalogue were collected and collated. We have received approximately 20 responses thus far. The DISI group is reviewing submissions. Comments will be fed back to authors in June. The editors, Russ Wright (LBL) and Ruth Lang (SRI), are aiming to have a rough draft of the entire document completed for DISI review by the end of June. SRI provided input to Brad Harrison of DEC Professional regarding the DISI X.500 implementation survey. Harrison's article will appear in their July issue. Ruth Lang (rlang@nisc.sri.com) ISO/CCITT DIRECTORY EDITING MEETING - SYNOPSIS ---------------------------------------------- An International Organization for Standardization (ISO) and International Telegraph and Telephone Consultative Committee (CCITT) collaborative editing meeting on the Open Systems Interconnection (OSI) Directory was held in Phoenix, Arizona from 22 April to 3 May 1991 with representatives from ten countries attending. The National Body and Liaison Organization ballot Westine [Page 25] Internet Monthly Report May 1991 comments on the Committee Draft (CD) and twelve Proposed Draft Amendments (PDAM) that were completed at the October 1990 meeting in Ottawa were resolved. All thirteen revised documents will be circulated for balloting at the same level on 3 June 1991. This ballot will close on 3 September and an editing meeting to consider comments will take place in Berlin in October, 1991. Draft International Standard (DIS) output is expected from the Berlin meeting. The replication and access control models are considered stable; however, the Directory and Directory System Agent (DSA) models, abstract services, and distributed operations parts of the standard need to be aligned with the replication and access control models. The most controversial decision concerning replication was the choice of the Reliable Transfer Service Element (RTSE) for recovery for replication. Some members of ISO do not believe that RTSE fits the OSI model. However, the Directory Group believes that it is the only solution practical for the 1992 standard. Going into the meeting, the documents for distributed operations and schema (directory models) needed the most work. At the previous meeting in Ottawa, U.S. participants had concentrated on the replication and access control documents. The U.S. position is that all documents must progress together, so a major effort was made this time to revise the distributed operations and schema PDAMs. Document Summary: The CDs and PDAMs being prepared for ISO balloting are listed below. The official titles are listed with the descriptive titles shown in brackets followed by reference number and JTC1/SC21 number.

Release 0.1.1 incorporates: o changes for DAP interoperability with QUIPU and the OSIWARE X.500 product, o some restructuring of the database tables to support enhanced search performance, o improvements in a few areas such as correct handling of the root and more latitude in the configuration of context prefixes, and, o a number of bug fixes. The third meeting of the government-wide X.500 Pilot, sponsored by GSA and NIST, is scheduled for June 18th. Work is focused on further extensions to the draft schema document. Richard Colella (colella@osi.ncsl.nist.gov) PARADISE -------- The central DSA is being closely monitored. A cause of the "watchdog" problem reported last month has been found (X.25 RESETs). A patch has been applied to the DSA software, but this appears to only partly fix the problem. A new fix is being worked on. Belgium, Ireland and Israel have now joined the pilot (see below), although access to all three countries has not been good. There have been further interoperability tests with the French PIZARRO implementation, but there is currently a problem at the Westine [Page 27] Internet Monthly Report May 1991 presentation level of the OSI stack which is being looked into. The first version of the "de" interface for the Central DUA service is now ready and being tested by the project. It will be made available to the PUNTERS group for beta testing and to elicit comments in the second week of June. A version of the software for a packaged DSA based upon ISODE is now ready, and will be made available for delivery once it has been decided whether to go with version 6.8, or to wait for the next full release, 7.0, which is expected very soon. The project produced the PARADISE International Report in both electronic and brochure form. The brochure was made available for the RARE Networking Conference held at Blois, France from 13-16 May. It is hoped to repeat the report every six months with electronic updates maintained regularly. A locality node, l=Europe, was set up with the intention of establishing a base for European multinational organizations to provide pointers to organizational entries below the country level of more than one European country. Site Reports: The Belgian DSA is based at the University of Brussels and is managed by Nils Meulemans running a QUIPU DSA (cn=Woolly Spider Monkey). The Israeli DSA (cn=Dorcan Gazelle) is based at the Hebrew University in Givat Ram, Jerusalem and managed by Juliana Solomon. The Irish Root DSA (Irish Elk) joined the global DIT this month. This DSA is running at Trinity College in Dublin and uses DEC X.25 Access for Ultrix to connect to IXI. Network performance is a problem, but the links are being upgraded soon. Currently there are only about 100 entries pertaining to the local site, but we hope that other universities and research institutions will be included later in the year. Any queries should be addressed to Donal O'Mahony (omahony@cs.tcd.ie). Portugal The Portuguese Pilot Directory Project is managed at the University of Minho, Data Communications Centre of the Department of Informatics, under a contract with FCCN (Fundacao de Calculo Cientifico Nacional), the national foundation in charge of the Portuguese Academic Network (RCCN). Westine [Page 28] Internet Monthly Report May 1991 The Pilot Directory Project started in May 1991 and its plan consists of four phases: o installation of a master DSA for PT, local connectivity tests with DSP and DAP protocols, interfaces with e-mailers and connection to the European PARADISE pilot (May-July, 1991) o preparation phase: definition of the DIT structure, collection of information for the pilot service on a limited and selected scope and the gathering of experience in the management of the service (June-August, 1991) o distribution phase: set-up of DSAs in other sites (Universities and R&D Laboratories) and connectivity tests (September-November, 1991) o production phase: use in the RCCN (December 1991 - ...) Contacts for the Portuguese Pilot Directory Project are Joaquim Macedo (macedo@uminho.pt) and Fernando Pinto (fernando@uminho.pt). David Goodman (d.goodman@cs.ucl.ac.uk) PARADISE Project Manager PSI DARPA/NNT X.500 PROJECT --------------------------- In response to substantial comments received on NADF-123, revisions were made to the document, which will be submitted in revised form at the upcoming North American Directory Forum meeting. Development is under way on an MSDOS front-end to the information available in the PSI White Pages Project. It is intended that this software tool will eventually provide access to White Pages information from IBM PCs and compatibles that support FTP Software Inc.'s PCTCP stack. Wengyik Yeong (yeongw@psi.com) PSI WHITE PAGES PILOT PROJECT ----------------------------- As of June 4, 1991, there are 75 organizations participating in the White Pages in the United States of America. New organizations added in the past month are: University of Pennsylvania Westine [Page 29] Internet Monthly Report May 1991 Oakland University In an effort to improve the general level of service afforded by the White Pages, organizations whose DSAs had longstanding reachability problems were 'pruned' from c=US. The following organizations have been deleted from the c=US arc of the DIT: Advanced Decision Systems Carnegie Mellon University NCI National Institute of Health University of Colorado at Boulder University of Rochester Beta testing was completed on a front-end to the PSI White Pages for the Macintosh. Version 1.0 of this shareware software is now available for anonymous ftp from uu.psi.com [136.161.128.3] in pilot/PSIWP.Hqx. This shareware has also been contributed to the USENET group comp.binaries.mac. Wengyik Yeong (yeongw@psi.com) SG-D MHS-MD ----------- SG-D MHS-MD just concluded a meeting held at the State Dept. in Washington, DC. Progress includes the revision of the draft procedures for MHS MD name registration. A tentative agreement was reached on the structure for resolving how ANSI registered national standing names can be used for MHS MD names, and also used as a "stem" for constructing names using a construction syntax to build additional nationally unique names for use as MHS MD names. This tentative resolution is to be fleshed out in the draft procedures for review and discussion at the next meeting on September 16-17 at the US Dept. of State in Washington. A discussion of the issues regarding how to organize a US National MTS (backbone) network of ADMD service providers was opened. This involves consideration of various alternative schemes; among them is an arrangement similar to that advocated in the UK scheme, which uses value for the ADMD name. We are soliciting contributions on this topic. SG-D MHS-MD is not yet focusing on issues of Directory Services.

Some major draft decisions were made in St. Louis: 1) The WG agreed on an X.400/RFC-822 address mapping scheme for the US Internet community (will be described later in this Newsletter). 2) A minimum solution for X.400 routing, using a structure of I-WEPs, was adopted. 3) Documents in the Internet X.400 Documentation will be used as a mechanism to describe and ensure end-user X.400 connectivity over different underlaying network protocol suites (RFC-1006/TCP/IP - TP-0/X.25 - TP-4/CLNP) Westine [Page 33] Internet Monthly Report May 1991 4) An outline of a new RFC: "Requirements for Internet PRMDs," was drafted. The project team will produce the draft RFC described in 4) to be reviewed at the next IETF in Atlanta (July 29 - August 2 1991). OPERATIONAL STATUS: The draft decisions made on address mapping, routing and documentation are to be implemented by the pilot operational Internet X.400 services now comprising 4 operational PRMDs: ARC, CDC, Hughes and XNREN. The number of real X.400 users is still very low. However with the new operational PRMDs, the number is growing. The following organizations are operational and interconnected as X.400 systems. Addressing examples are given in order to show what the X.400 addresses look like. The X.400 addresses are presented both in X.400 Standard Attribute (SA) form and in RFC 822 form.

The project is operating an RFC 987 gateway (PP) between the U.S. Internet mail service and the international R&D MHS Service (X.400). This gateway is also the experimental U.S. WEP (WEP = Well known Entry Point) in the COSINE MHS Service in Europe, and it is directly connected to other WEPs in Canada, Finland, France, Norway, Spain, Switzerland and United Kingdom. X.400 traffic to the other countries in the COSINE MHS Service, is routed via the Norwegian WEP operated by the UNINETT project. France, Norway, Spain and Switzerland are routing some of their X.400 initiated traffic destined to the U.S. Internet mail domains, via our gateway as an experiment. This means that messages initiated in X.400 can be kept in the X.400 "world" all the way to the U.S. and gatewayed Westine [Page 35] Internet Monthly Report May 1991 here, if necessary. Due to these routing experiments the monthly traffic through our WEP has increased considerably. TECHNICAL ASSISTANCE: The project is distributing the ARGO X.400 implementation to non-commercial organizations, and we are also offering assistance to organizations who are starting to use the PP X.400/RFC-987 gateway system from UCL, London. The assistance we offer is limited to operational issues, initial PP configuration, address mapping tables, etc. E-mail us if you would like such assistance. General software support should be obtained from the pp-support team in London. EXTERNAL PRESENTATIONS: The project was presented at the 2nd Joint European Networking Conference in Blois, France, May 13 - 16 1991. "X.400 in the Internet" will be presented at the INET '91 Conference in Copenhagen, Denmark, June 17 - 20 1991. VALUE ADDED SERVICES: The project team is developing a FAX gateway service between X.400 and FAX. Status so far is that a text file can be sent to a given fax number. More work has to be done to develop this into a useful service allowing end-users to use their X.400 User Agent to send a text message to a fax- subscriber in the U.S. It is a goal to negotiate agreements with other countries such that X.400 users in the U.S. also can send international fax using similar fax gateways in other countries. This service, when developed, will be made available for all X.400 users in the Internet X.400 service, and also on a bilateral basis to X.400 users in other countries. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Westine [Page 36] Internet Monthly Report May 1991 * * * Topic of today: * * * The "St. Louis decision" on address mapping. -------------------------------------------- The draft decision in St. Louis is valid for the U.S. Internet, and can also be viewed as a recommendation for communities outside the U.S. The address mapping issue can be split into two parts: 1) Specification of RFC-822 addresses seen from the X.400 world. 2) Specification of X.400 addresses seen from the RFC-822 world. 1) Specification of RFC-822 addresses seen from the X.400 world. The following is from the St. Louis minutes: "It was agreed that RFC822 addresses should be expressed using X.400 domain defined attributes. Furthermore, a special PRMD named "Internet" will be defined to facilitate the specification of RFC822 addresses. For example, an X.400 user will address an RFC822 recipient by constructing an X.400 address such as: /c=us/admd= /prmd=Internet/dd.RFC-822=user(a)some.place.edu/ Participating MTA's will be configured to recognize "/c=us/admd= /prmd=Internet/" as a special case. The presence of this address will cause a message to be routed to a regional RFC987 gateway. In effect, this special PRMD identifies a community of gateways to RFC822 recipients. This strategy is user friendly in that all users everywhere need only remember this one address, and it is efficient in that it avoids having to establish a single, common gateway which would tend to become a bottleneck and single point of failure." 2) Specification of X.400 addresses seen from the RFC-822 world. The following is also from the same minutes: "After considerable discussion, it was agreed that RFC822 users should be able to address X.400 recipients in RFC822/Internet terms. This implies the necessity of maintaining and distributing address mapping tables to all participating RFC987 gateways, at least in the short term. Other mapping strategies were discussed (loudly and enthusiastically), but it was shown that these alternate strategies would sometimes cause messages (or replies to messages) to pass through more than one gateway. Since this behavior would probably cause information to be lost in translation, it was quickly agreed that the alternate strategies were inferior to the good old table Westine [Page 37] Internet Monthly Report May 1991 driven approach. Nevertheless, it was also pointed out that some X.400 addresses do not map cleanly to RFC822 addresses, even when the table driven mapping strategy is used. For example, X.400 personal names which contain generation qualifiers, personal names which contain initials but no given name, and initials which contain periods cannot be mapped to RFC822 symmetrically such that a reverse mapping is possible. Similarly, X.400 addresses which contain X.121 address elements (sometimes used for expressing fax telephone numbers), unique UA identifiers, or physical addressing attributes cannot be mapped nicely. Consequently, it will be necessary for RFC987 gateways to generate RFC987 address syntax occasionally. It was recommended that our RFC should contain guidelines for the creation of X.400 personal names. In following these guidelines, users will avoid creating personal names which can not be mapped nicely between X.400 and RFC822. It was generally agreed that long term reliance upon static mapping tables is unacceptable. Therefore, it was agreed that the X.400 Operations Working Group should devise a strategy for using X.500 directory services instead. Another option could be to use the DNS system for this purpose, if the X.500 infrastructure appears to be too premature." In other words, in most of the cases RFC-822 users will not see the difference between an RFC-822 address and an X.400 address. Example: The X.400 address: C=us; ADMD=ATTMail; PRMD=CDC; O=CPG; S=Jordan; G=Kevin will from an RFC-822 user look like: Kevin.Jordan@cpg.cdc.com The mapping tables in the gateways will describe this mapping. The other way around, an X.400 user, will normally see the difference of an X.400 address and an RFC-822 address, because the RFC-822 address will be using PRMD=Internet and dd.RFC-822 (example): Westine [Page 38] Internet Monthly Report May 1991 The RFC-822 address: ok@subdomain.edu will from an X.400 user look like: C=us; ADMD= ; PRMD=Internet; DD.RFC-822=ok(a)subdomain.edu The decision to use Domain Defined Attributes (DDAs) requires modification of the current mapping table coordination procedures defined by the European RARE-WG1. Such modifications have already been discussed and some proposals are on the table. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Internet X.400 Project Contact Points: -------------------------------------- If you need information from the project, please look first in the catalog.txt file in our file server and check if there are some documents there that might give you the information you need.

Westine [Page 39] Presently we were in a very dark road, and at a point where it dropped suddenly between steep sides we halted in black shadow. A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù ENTER NUMBET 0016fldfnm.com.cn
