This IETF session included presentations by the chairs of the breakout groups from the Retreat: Russ Hobby (Advanced Applications), Bob Braden (Traffic Control and State), Vint Cerf (Security), Lyman Chapin (Multi-Protocol Architecture), and Dave Clark (Routing and Addressing). Summaries and slides will appear in the IETF Proceedings. Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- ANRG held a short video conference to discuss large scale simulation. No official minutes available. Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No progress to report this month. Bob Braden (Braden@ISI.EDU) Westine [Page 3] Internet Monthly Report July 1991 INTERNET PROJECTS ----------------- BOLT BERANEK AND NEWMAN INC. ---------------------------- Terrestrial Wideband Network (TWBNet) and ST/IP Gateway During July, we completed the development of a new version of WPS software that supports the use of an intelligent I/O board (BI4). This added hardware will allow reduction of the TWBNet per-node forwarding delay by about 67%: from approximately 21 msec/node to 7 msec/node. It will also allow the use of a smaller cell size (approximately one half the current size), which will let applications reserve bandwidth with finer granularity. During the month of July there were twelve video conferences using the TWBNet. Of these conferences, three involved simultaneous connections to 4 different conferencing sites, four were point-to- point, and one was a demonstration for the University of Oslo. There were four conferences using the DARTnet technology on the TWBNet. Of the twelve conferences, three involved the conferencing suite at UCL and one conference involved both the new conferencing site at Los Alamos National Laboratory and the Warrior Preparation Center in Germany. These conferences supported the US-UK Fat Pipe Operational Management Group (OMG), Synchronization Protocol work, and a DARPA NOS contract program review. Also during July there were two Simnet exercises. These exercises involved two sites and each had a duration of one week. Inter-Domain Policy Routing During the month of July, the IDPR working group of the IETF released three documents: an update of the architecture description, a configuration guide, and a MIB. A fourth document, an update of the protocol specification, will be released in early August. BBN prepared the architecture description, protocol specification, and configuration guide, and SAIC prepared the MIB. SAIC is generating a "gated" version of IDPR and is also working on the MIB software. BBN is working on the configuration software and will also provide some assistance in the gated effort. Westine [Page 4] Internet Monthly Report July 1991 The IDPR working group met for two sessions at the Atlanta IETF meeting. We discussed the two newest documents, namely the configuration guide and the MIB, and are looking forward to constructive criticism on both. Steve Storch (sstorch@BBN.COM) COMMERCIAL INTERNET EXCHANGE (CIX) ---------------------------------- The first CIX site is operational and passing traffic. CIX-WEST is located in the William's Telecommunications POP in Santa Clara, CA with dedicated hardware. Initially, CIX-WEST will connect Alternet, CERFNet, and PSINet. Currently, the PSINet and Alternet T1 lines are operational. CERFNet is expected to be on line in the next few days. At the present time, 261 networks within Alternet and PSINet are using the CIX-WEST. Approximately 3000 domains are using the CIX- WEST for electronic mail services. Traffic statistics are being gathered via SNMP. Traffic reports will be included in future Internet Monthly reports. The domains cix.org and cix.net have been registered with the NIC. A machine "cix.org", located on CERFNet, has been set up to receive mail. Send mail to info@cix.org for information regarding the CIX. Mark Fedor (fedor@uu.psi.com) FEDERATION OF AMERICAN RESEARCH NETWORKS (FARNET) ------------------------------------------------- This report includes events for both June and July. FARNET has moved into new office space at 100 Fifth Avenue, 4th floor, Waltham,MA 02154. The telephone number is (617) 890-5120. You can also dial 1-800-72-FARNET (the extra T disappears). Our fax number is (617) 890-5117. Susan Estrada, Vice President of FARNET and director of CERFnet, has been appointed Co-Area Director of the new IETF Operations Area Directorate. For more information, contact estradas@nic.cerf.net. Westine [Page 5] Internet Monthly Report July 1991 Several FARNET members attended the INET 91 meeting in Copenhagen June 18-20. Glenn Ricart, president of FARNET and SURAnet principal investigator, chaired asession on collaboration technologies. Ira Fuchs of CREN chaired a session on North American network activities that included presentations by Eric Aupperle of MERIT, Richard Mandelbaum of NYSERNet, and Guy Almes of Sesquinet. Richard Mandelbaum also chaired a session on networks of the year 2000. Also making presentations at the conference were Laura Breeden (Internet operations in a distributed international environment), Allan Weis of ANS and William Schrader of PSI (commercial services in the Internet), Lynn F. Ten Eyck of the San Diego Supercomputer Center (worldwide networking in chemistry and molecular biology),and Susan Calcari of MERIT (education over the international internet). FARNET announced a discount agreement with PSI to provide individual dial-up services for institutions of higher education that participate in FARNET membernetworks. For more information, contact FARNET, PSI or your regional network provider. FARNET attended an open meeting at the National Science Foundation on June 10 for the purpose of providing feedback and obtaining information about the draftNSF RFP for Network Information Services, due out in the fall of 1991. Laura Breeden attended the Federal Networking Council meeting July 10-11. FARNET will be working with the Federal agencies involved in the NREN program, such as NASA, the Department of Energy, and NSF, to improve the quality of end-to-end service in the Internet. Final plans for the August FARNET meeting were made. The meeting will include a two-day workshop on connectivity among the midlevel networks after the current backbone agreement expires in November 1992. In addition to FARNET member representatives, the workshop will include a number of invited guests from other NREN stakeholders, such as carriers, libraries, and Federal agencies. Results of the workshop will be made available in a paper in September, which will include recommendations of the FARNET membership to NSF about how best to support inter-regional connectivity. The FARNET plenary and business meeting will be held immediately after the workshop, on August 14. by Laura Breeden, (breeden@farnet.org) Executive Director, FARNET Westine [Page 6] Internet Monthly Report July 1991 ISI --- GIGABIT NETWORKING INFRASTRUCTURE Joyce Reynolds, Jon Postel and Bob Braden travelled to the IETF Conference in Atlanta, Georgia, July 29 through Aug 2. Bob Braden and Jon Postel attended a symposium on GIGABIT Networks, in Washington D.C, Jul 14-17. Five RFCs were published this month. RFC 1237: Colella, R. (NIST), E. Gardner (MITRE), and R. Callon (DEC) "Guidelines for OSI NSAP Allocation in the Internet", July 1991. RFC 1244: Holbrook, P. (CICNET), and J. Reynolds (ISI) "Site Security Handbook", July 1991. RFC 1245: Moy, J., "OSPF Protocol Analysis", Proteon, Inc., July 1991. RFC 1246: Moy, J., "Experience with the OSPF Protocol", Proteon Group, July 19991. RFC 1247: Moy, J., "OSPF Version 2", Proteon, July 1991. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING No Internet news to report this month. Steve Casner and Eve Schooler (casner@ISI.EDU, schooler@ISI.EDU) JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK --------------------------------------------- General information on JvNCnet is available on-line from nisc.jvnc.net. Use "telnet nisc.jvnc.net", username "nicol" and no password. Errata for network availability, June Internet report. The correct availability for June, 1991 is 99.91%. Westine [Page 7] Internet Monthly Report July 1991 The traffic for June was 1,705,976,387 (combined incoming plus outgoing) packets. Four highest contributors were Rutgers University (12.99%), Princeton University (12.06%), UPENN (5.76%), and Yale (5.57%). It is anticipated that the Princeton T3 node installation will be completed by the fall, 1991. JvNCnet is planning the next symposium that will spotlight network applications. For further symposium information, please send inquiries to "nisc@jvnc.net." For more NOCOL information (JvNCnet Network Operations Center On- Line software package) and for acquisition of this application without charge, please send email to "nocol-info@jvnc.net." At the June 28 JvNCnet Regional Meeting, three members explained their services or developing services which are Internet-accessible via JvNCnet. Ms.Stephanie Suplee, Esq, Sr. Account Executive and Mr. Alan Huber, Sr. Technical Consultant, Mead Data Central, both talked about MDC's LEXIS/NEXIS services as well as "how to" connect to these databases. Mr. Anthony Abbott, Sr. Vice President of Meckler Publishing (Westport, CT), described the joint Meckler/JvNCnet NICOL project. To be built in stages, Meckler's computer-based technology database will "live" in the menu-driven NICOL infrastructure and serve as an "electronic warehouse" for its technology, newsletters, conferences, periodicals, and books. The first round of development has Meckler working to create a contents list of their 14 periodicals and selected information technology books (since January 1991) for installment in NICOL. The first-tier level of the Meckler directory will contain a table of contents of all publications and conferences. A searcher will scan a bibliographic shell and then access the second tier leading to an index for full text documents. Meckler ultimately expects users (especially the information specialist, librarian, academic, and persons interested in electronic-based information and resources), to select and view a full text document; to access a copy via ftp; to order from book and periodical catalogs; and to register for conferences. CD-ROM Librarian Index 1986-1990 and text of CD-Rom Librarian for May 1991 now reside in NICOL's Meckler directory. Mr.Todd Vander Does, Systems Programmer at AMS described "e-MATH", a service developed at the American Mathematical Society with Westine [Page 8] Internet Monthly Report July 1991 partial National Science Foundation funding. Directed to academic faculty; students; public, private, and governmental researchers; AMS, MAA, and SIAM members, librarians, and human resource managers, e-MATH provides a menu-driven repository of network tools and information. Its contents are particularly helpful to the mathematics community. Document ordering, employment listings, MR classifications, AMS journal style files, combined memberships lists, and AMS platform-independent enhancements of TeX typesetting language (AMS-TeX, AMS-fonts, AMS-LaTeX) are currently offered. Anticipated inclusions to the updated version will: * enhance collaboration and support in the form of electronic conferencing and bulletin boards * establish an electronic research journal to widen accessibility of research information * centralize ARCHIE and IMP for network resource access The "ftp"," mail","more", and "telnet" functions are e-MATH compatible and e-MATH operates on an Ultrix-based DECsystem 3100. Access: Telnet e-math.ams.com. Login and password are e-math. Electronic inquiries: support@e-math.ams.com. by Rochelle Hammer LOS NETTOS ---------- OSPF testing continues. Walt Prue (Prue@ISI.EDU) MERIT/MICHNET ------------- June-July 1991 Alma College, located in Alma, Michigan, and Northwest Michigan College, with campuses in Traverse City and Cadillac, have become MichNet's newest affiliates. Both of these schools will get their network hookups early in the fall. An initial implementation of PPP (Point-to-point protocol) has been implementedin MichNet and is available to dial-in as well as traditionally connected users. This initial implementation allows for basic service within the state of Michigan. Basic service includes telnet, ftp, quote of the day, and finger service at hosts within Michigan. Later this year authentication will be added to Westine [Page 9] Internet Monthly Report July 1991 the PPP implementation within MichNet, which will allow PPP users access to the greater Internet. At their June 10th meeting the Merit Board directed the staff to investigate what role Merit should play to encourage video networking in the state of Michigan. The goal is to report back to the Board with a recommendation and business plan in January 1992. The Merit staff had previously written a report for its member schools recommending that any video codex equipment that is purchased should meet the H.261 standard. At this time, the GPT codex is furthest along in implementing this standard. Merit/MichNet staffers Ellen Hoffman, Mark Knopper, Glenn McGregor, Dana Sitzler, and Chris Weider attended the IETF meeting in Atlanta in July. At that meeting Knopper and Weider presented 6 proposed RFCs to the OSI-DS working group, which went back to the authors for rewrite. Weider, along with co-authors Joyce Reynolds (ISI) and Sergio Heker (JvNC) had a proposed RFC accepted as an Internet Draft at the DISI working group. This new Internet Draft is a FYI, intended as a tutorial on X.500. McGregor's Internet Draft on PPP Header Compression was accepted by the PPP working group into full RFC status. As of August 20, users at workstations located in a public area or who dial into MichNet will be subject to some restrictions about which telnet ports they connect to. They will be able to connect to ports 17 (quote of the day), 23 (telnet), and 79 (finger) without any new procedure. But to connect to any other port they must supply an authorization code and a password. This restriction applies even to hosts within Michigan. Users on private, hardwired connections to MichNet do not go through this authorization procedure. Systems managers will be able to register specific ports on their hosts which they wantto be available without additional authorization. by Pat McGregor (patmcg@merit.edu) MITRE Corporation ----------------- Bill Barns, Walt Lazear, Shari Galitzer, John McGuthry, Allison Mankin, and Rick Wilder attended the IETF in Atlanta. Walt made presentations on MITRE's OSI work to the Network OSI Operations and X.400 Operations working groups. John and Walt continued preparations for the OSI Infrastructure demo at Interop '91 in October. X Windows over a full OSI protocol stack is the near-term focus for the demo support. Westine [Page 10] Internet Monthly Report July 1991 Shari has started an effort with Kinesix to tailor their SAMMI product to the internet management environment. A simple protocol tool will gather information and SAMMI will be used to display and summarize it in graphical form. Walt Lazear (lazear@gateway.mitre.org) NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NEARnet has grown to 89 members. NEARnet operations continue to be stable. Access to the NSFnet has been interrupted several times by problems with the T3 network. The most serious of these was a 10 hour outage on July 9 when the T1 backup path was also unavailable. Most outages have been less than 15 minutes during which time routing has switched from the T1 to the T3 or vice-versa. NEARnet continues deployment of DECNET for ESNET. NEARnet is planning to participate in OSI routing for the Interop Conference. by John Rugo NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Karen Roubicek gave a presentation on the Internet at the National Library of Medicine in Bethesda, MD. The STIS (the Science & Technology System at the National Science Foundation) announcement has been added to the NSFNET portion of the Info-Server. To receive this announcement from the Info-Server, send a mail message to: info-server@nnsc.nsf.net, in the body of the message type: Request: nsfnet Topic: stis This request will automatically send you the STIS announcement. The NNSC distributed additions to chapters 3 and 5 of the Internet Resource Guide. Westine [Page 11] Internet Monthly Report July 1991 John Curran participated in the DISI and NISI Working Groups at the IETF. Corinne Carroll NSF BACKBONE (Merit) -------------------- NSFNET Project (Merit Network, Inc.) Total traffic on the NSFNET T1 and T3 infrastructures measured 8,742,898,058 inbound packets, representing all inbound traffic during July, 1991. NSFNET T1 infrastructure inbound traffic totaled 7,976,722,283 packets during July, 1991. This total includes packet traffic entering the T1 network from the T3 network. Networks announced to the T1 NSFNET number 3086 as of 30 July; of this total, 1012 are foreign networks. NSFNET T3 infrastructure inbound traffic totaled 1,848,194,544 packets during July, 1991. This total includes packet traffic entering the T3 network from the T1 network. Networks announced to the T3 NSFNET numbered 616 as of 30 July. Redesign of the T3 infrastructure to accommodate the eight nodes scheduled for T3 expansion in Phase II continues. A new C-NSS architecture has been deployed throughout the east coast and most of the midwest. Three new C-NSS sites have been added at New York, Greensboro and St. Louis. Four new links have been added into the infrastructure, increasing the number of T3 links to 19 in support of Phase II T3 expansion. Elise Gerich of Merit Internet Engineering attended "An NREN Workshop," held at NASA-Ames on July 9-11. Eric Aupperle, President of Merit Network, Inc., and Bilal Chinoy of Merit Internet Engineering attended the Symposium on Gigabit Networks July 14-17 in Washington, D.C. Gerich and Jordan Becker, of ANS, presented the NSFNET network status report to the plenary session of IETF convened in Atlanta. Several members of Merit's Engineering and Information Services groups attended IETF, chairing working groups for NISI, X.500 and OSI, as well as participating in the overall program: Sue Hares, Ellen Hoffman, Dale Johnson, Mark Knopper, John Scudder, Dana Sitzler, Pat Smith, and Chris Weider. Jo Ann Ward (jward@merit.edu) Westine [Page 12] Internet Monthly Report July 1991 PREPNET ------- PREPnet had two organizations join in July: WEA Manufacturing, Inc. and Carnegie Group, Inc. WEA Manufacturing will be connected to the Scranton hub at 56Kbps, and Carnegie Group will be connected to the Pittsburgh hub at 56Kbps. PREPnet NIC (prepnet+@andrew.cmu.edu) SAIC ----- The second step in the gated port has been completed. IDPR has been integrated into the current release of gated software. Initial testing of this implementation has begun. IDPR currently uses its own parser for its configuration files. It is not clear that IDPR configuration will be integrated with gated because of its complexity. RFC 1241 for encapsulation has been introduced as an experimental protocol. This encapsulation scheme has some features that differ from IDPR encapsulation. Work will continue on this protocol for use in the Internet and possible use with IDPR. Planned activies: Testing of the newly integrated software will continue. Further integration will replace more facilities in the old prototype with gated facilities. Old interfaces between the IDPR sub-protocols still need to be cleaned up for the single-thread environment. A design document for IDPR in gated will be completed by the end of August. A crucial part of the continuing integration effort is the tying of BBNs configuration work into this implementation. Work on using gated SNMP management facilities for the IDPR MIB will also begin. Robert Woodburn (woody@sparta.com) SAN DIEGO SUPER COMPUTER ------------------------ This will summarize the changes since our last report. We are continuing our cooperation with Merit to resolve some routing issues on the T3/SDSC connection. We are looking forward to the growth of the NSF's T3 network and plan to make full use of Westine [Page 13] Internet Monthly Report July 1991 it in the near future. We have converted our UltraNet/Cray connection from HSX to HiPPI. This is the first step in the installation of the CASA testbed HiPPI crossbar switch. Also on the Ultra, we have run several timing tests - Cray to/from UTS on the Amdahl. While these were not what we had hoped for, Amdahl is installing mods to increase the speed. Our Proteon p4200 router has been upgraded to 9.1 software. Our Cisco AGS has also been upgraded to the latest release. We also spent a large amount of time, with CERFnet, tracking down the route caching bug. You can see the full details in the CERFnet report. During July we gatewayed over 150,000 mail messages through our Software Tools mail software. Our FDDI network has had several changes since Feb. Today, SDSC has a single FDDI network which has three NSC DX series chassis configured as follows: DX1 - Network: FDDI plus N220(IBM BMC@3MB), N400(VAX and SUNs), IP coprocessor DX2 - Network: FDDI plus N130 (CRAY interface), IP coprocessor DX3 - Network: FDDI plus HC50 (2-trunks), 4 Ethernets, IP coprocessor The HC50 (old HyperChannel) also connects to the following: A400 - Network: HC50 (VAX and SUN access), A223 - Network: HC50 (IBM BMC), DX5 - Network: HC50 plus dual N220(IBM BMC) Additionally the FDDI ring has a DEC concentrator connected to the NSFnet T3 router and two VME based SUNs via CMC interfaces. During the Spring we have had a series of problems on our ring and with our NSC equipment. All have now been corrected. The description and resolution of problems is set out below. As an aside, SDSC would like to thank NSC for their help in resolving these issues. The assignment of an NSC engineer to SDSC for several weeks was a big help in the resolution. o Byte dropping-7th byte from end of buffer (output from the IBM). IBM) This problem was detected between DX1 and DX2, DX1 and an A400. The problem persisted for several months even though Westine [Page 14] Internet Monthly Report July 1991 all the hardware between the IBM channel and the DX1 chassis had been replaced. This problem disappeared with no specific resolution (not seen since March.) o Bit 2**4 picking and dropping (input to the CRAY). This problem was always on a 64 word boundry and was only seen when data was transfer inbound to the CRAY. The solution was to shotgun DX2 with spare NUC and MEM cards plus upgrading all DX's to NUC code to 7.1. o 32bit shifting (input to the CRAY) This problem was only visible when the archival system was transfering to the CRAY. The processor that NSC uses on the FDDI board works in 32bits. It was unclear if the sending or receiving FDDI was causing the problem. Upgrading from NSC Series B FDDI to Series C FDDI cards stopped the errors. o FDDI FIFO overrun (input to the Cray) This problem was visible only when large files were transferred from our archival system to the CRAY. Occasionally a transfer would have a bad checksum - with a checksum value of zero. After much effort, it was discovered that the NSC FDDI FIFO clears its buffer and that when an overrun occures the application on the Cray did not properly handle this [new] error status. The applications's checksum caught the zero'd block, then recovered. DISCOS has implemented code to handle this error status (we were their first FDDI site.) This turned out not to be a NSC problem, but their assistance in resolving it was vital. o NSC WRAP diagnostic failures (only associated with the FDDI network) The NSC CE's were able to demonstrate the 32bit shift by running the NSC WRAP diagnostic ( WRAP would report an AD data miscompare error when the shift occurred.) The CRAY zero checksum error was demonstrated with WRAP as AD length miscompare (this is when a FIFO would overrun. The WRAP test required large buffers (FFF7) running on a busy network to see the overrun errors.) The 2**4 twiddle and the 7th byte drop were undetected by WRAP. by Paul Love SRI ---- The cumulative total of all IP numbers now assigned is now 31,206. See the table below for a breakdown of these assignments by class. There are now a total of 1,323 Autonomous System Numbers (ASNs) assigned. There are currently a total of 3,052 domains registered. This includes the root domain, 63 top-level domains, 2,925 second- level domains, and 64 third-level MIL subdomains.

A paper on an anomolous performance problem in RPC over TCP was circulated to the community - it is available fro anonymous FTP from cs.ucl.ac.uk in docs/rpcperf.ps. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Packet-loss rates from campus to the College Park NSFnet NSS have been substantially reduced, thanks to efforts of the SURA and UDel technical crew. Future upgrades to SURA equipment are expected to reduce the loss rates, now in the three-percent range, still further. 2. John Elias and his crew developed a six layer board for the highball node controller card. They are now working on a preliminary transceiver design suitable for speeds to 200 Mbps, as well as drivers and software for synchronization and scheduling. Work also continues on algorithm simulation and Westine [Page 16] Internet Monthly Report July 1991 system robustness. 3. The DARTnet time-synchronization subnet involving ten routers and over 18 test hosts has been completely redesigned. Preliminary measurements suggest an ultimate timekeeping accuracy well below a millisecond is possible. 4. We have received and installed an Austron Global Positioning System timing receiver. This incredible device provides time to within 150 nanoseconds relative to UTC and argues with the campus surveyor as well. It now synchronizes one of our fuzzballs. Along with the local utility Delmarva Power, we are working on timekeeping support for SPARCstations. 5. We continue to work on audio, video and interface gear to support real-time conferencing. We plan to use this for DARTnet experiments in synchronization, Highball applications and general teleconferencing. Dave Mills attended the Symposium on Gigabit Networks held in Washington, DC. Dave Mills (Mills@UDEL.EDU) WISCNET ------- The WiscNet Board of Directors met on July 25, 1991 at the University of Wisconsin - Stout campus in Menomonie Wisconsin. Business included: New officers were elected. Charters for the finance, membership, and publicity committees were approved. The finance committee reported on procedures for member fee billing including penalties for late payment and on alternatives for maintenance of T1 multiplexor equipment. The user services committee reported on activities including recommendations for additional NIC support. A proposal for maintenance of electronic mailing lists was approved. An upgrade of the Marquette - UW-Milwaukee link from 56K DDS to T1 was approved. The operating agent report included: Westine [Page 17] Internet Monthly Report July 1991 The UW-Madison - State network T1 links have been switched to fiber. V.35 cables have been reworked to reduce short outages. UPS equipment is now being monitored through Cisco router secondary console ports. Bills have been sent to members for 91-92 fiscal year. Developed automated tool to load router configurations. Distributed WiscNet information packet to prospective new members. Marquette University and UW-Milwaukee traffic is now flowing over WiscNet rather than over back door to UIUC. Limited traffic statistics were distributed. The UW- Milwaukee link (224Kbps) is about 50% busy and the Marquette - UW-Milwaukee link (56Kbps) is about 70% busy. Michael Dorl (dorl@macc.wisc.edu) Westine [Page 18] Internet Monthly Report July 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 Working Group [X] o IETF DISI Working Group [X] o Field Operational X.500 Project - ISI - Merit - PSI [X] - SRI o National Institute of Standards and Technology [X] o North American Directory Forum [X] o OSI Implementor's Workshop [X] o PARADISE Project o PSI DARPA/NNT X.500 Project [X] o PSI WHITE PAGES PILOT [X] o Registration Authority Committee (ANSI USA RAC) [X] o U.S. Department of State, Study Group D, MHS Management Domain subcommittee (SG-D MHS-MD) [X] [X] indicates no report this month Steve Hotz (hotz@isi.edu) DS Report Coordinator FOX -- FIELD OPERATIONAL X.500 PROJECT -------------------------------------- The FOX project is a DARPA and NSF sponsored 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 --- Jon Postel convened an early morning meeting of the FOX group at the Atlanta IETF, which included participants from all of the FOX contractors as well as Tim Howes (UofM), Richard Colella (NIST), and Paul Mockapetris (DARPA). Hotz also participated in the OSI-DS and DISI working group Westine [Page 19] Internet Monthly Report July 1991 meetings, and met informally to discuss FOX concerns with various members of the X.500 community. Steve Hotz (hotz@ISI.EDU) MERIT ----- o Submitted schemas for the following as Internet Drafts: - Information Resources - K-12 Educational Resources - Libraries - NIC Profiles o Continued development of an e-mail based registration and query system for NIC profiles and K-12 people and resources. o Installed ISODE 7.0 and new DSA for FOX related X.500 activities. o Convened MichNet working group on X.500. The goals of this group are to promote the use of X.500 among statewide Merit members and affiliates. o Developed a plan for coordination and evolution of network infrastructure information and WHOIS information. o Installed sendmail with X.500/alias lookup for Sprintmail gateway. o Mark Knopper, Chris Weider, and Tim Howes participated in OSI-DS and DISI working groups at the Atlanta IETF meeting. Mark Knopper (mak@merit.edu) SRI ---- SRI continued correspondence with NIST regarding problems with running Custos 0.1.1. NIST fixed a bug in the Custos DBMS library, and sent replacement code files to SRI. SRI will test the patches in early August. Russ Wright (LBL) and Ruth Lang completed the compilation of the keyword cross-reference list, formatted the document, and held reviews with implementation description authors and with the Westine [Page 20] Internet Monthly Report July 1991 DISI working group. Near the end of the month, a DISI document, "A Catalog of Available X.500 Implementations," was published as an Internet-Draft. As a results of comments received at the DISI meeting at the Atlanta IETF meeting, the document will be revised, sent out for final review to DISI, and subsequently submitted as an FYI RFC. Chris Weider (Merit), Mark Knopper (Merit), and Ruth Lang held a phone meeting to discuss three related topics: (1) The future of "o=Internet@ou=Site Contacts" and "o=Internet@ou=WHOIS". (2) The status of two OSI-DS Internet-Draft Documents pertaining to the schema and tree structure for network infrastructure information. (3) Replication of "ou=Site Contacts" and "ou=WHOIS". Merit and SRI will work together to combine the two branches of "o=Internet" described in (1) in order to reduce redundancy. The results of this work will be reflected in the two Internet- Draft documents mentioned in (2). In addition, each agreed to pursue the configuration of hardware resources required to support the replication described in (3). Progress on these areas will be reported in subsequent monthly reports. Ruth Lang will participate in the Interop 91 panel session entitled "Fielding Operational X.500 Directory Services. Presentation materials for that panel session were prepared and delivered to Interop in early August as required. SRI responded to several queries regarding the availability of NIC WHOIS data; these queries had been posted to the ietf and tcp-ip mailing lists. Ruth Lang and Ken Harrenstien participated in a FOX project phone conference meeting held on July 9. Ruth Lang attended IETF held in Atlanta during the week of July 29. Ruth Lang (rlang@nisc.sri.com) PARADISE -------- Within PARADISE, PTT Telecom (the Netherlands), PTT Switzerland and Telecom Finland are performing a study on the suitability and expected acceptance of X.500-based Directory Services for European Westine [Page 21] Internet Monthly Report July 1991 PTT's and service providers. An extensive questionnaire has been formulated and was distributed this month with a view of eliciting information for this study. Respondents are expected to receive an overview of the results of the non-confidential parts of the questionnaire towards the end of 1991. The PTT Telecom Research Laboratories based in Groningen, the Netherlands, is also offering diagnostic test-services for the PARADISE participants for the duration of the pilot. PTT Research is a participant in the development of test-suites for X.500 Directory tests within the European CTS2 project. In this project a group of European companies have written and implemented test suites for the Session, Presentation, ROSE, ACSE and DAP protocols and for both DUAs and DSAs. Of these, the DSA/DAP test suite was designed and implemented mainly by a PTT Research group which will probably also be involved in establishing test suites for DSP and distributed Directory operations. An EC-accredited CTS2 Conformance Testing Service will be set up by the end of 1991. For the PARADISE testing service the Groningen labs will use a DANET test system which will allow conformance, interoperability and robustness testing on specified implementation problems. For further information, contact: John van der Aalst (jvanderaalst@eurokom.ie). This month's site report is from: AUSTRIA Austria is running 3 QUIPU DSAs. The "main" DSA for Austria (called "Piranah") is located in Graz and holds general information about all universities in Austria. Additionally it stores detailed information about the staff of the University of Technology in Graz, e.g. e-mail addresses, phone and fax numbers, postal addresses, etc. The University of Vienna and the University of Technology in Vienna have had their own DSAs (called "Rockhopper Penguin" and "Yellow-legged Tortoise") since mid-July and have started to gather and store information about their local staff. The X.500 project of ACONET (the Austrian Scientific Network) is entering its second stage now. The first stage concentrated on the establishment of an X.500 service and its technical, functional and inter-communicational aspects. The second stage will focus on the development of an Information System for Universities and therefore concentrate on organizational and structural aspects as well as on the user interface (ACONET will probably have to develop their own user interface). We are thinking about storing on an X.500 basis information which is to be collected for the following international projects supported by the European Commission: Westine [Page 22] Internet Monthly Report July 1991 "TRACE" -- concerning relevant information about universities, colleges, etc in Austria; and "ERASMUS" -- concerning information which should make it easier to exchange, for example, students or staff from universities in different countries. The advantage of an X.500 solution would be that this information would be available worldwide (as it should be) and would be stored where it is gathered and administered (in contrast to the TRACE approach with their central storage concept). The contact for the Austrian pilot is: Florian Schnabel (schnabel@at.ada.tu-graz.edvz).

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 0016www.gloffer.com.cn
