NEW IAB CHAIR-ELECT The Internet Activities Board is pleased to announce that Lyman Chapin has agreed to serve as its chairman beginning July 1, 1992. During the period July 1, 1991 to June 30, 1992, he will serve as chairman-elect and work with Vint Cerf, who will continue as chairman. Chapin is employed at Bolt Beranek and Newman as its chief network architect. In addition to his duties on the IAB, he is also chairman of ANSI X3S3.3, and has just been elected chairman of ACM SIGCOMM for 1991-1993. B. INTERNET SOCIETY The phenomenal growth of the Internet, and particularly the increasing vendor and commercial involvement, have presented new challenges for the IAB and its task forces. The IAB continues to explore policies and procedures to manage the Internet and its evolution during this explosive growth, while maintaining as much as possible of the traditions which have led to that success: openness and cooperation within the Internet community. The incorporation of the Internet Society as a non-profit professional society will provide a legal framework for the IAB. The fact that the IAB has no official standing has been both a strength and a weakness for the Internet endeavor. The desire to address the weakness without losing the strength is one motivation for the creation of the Internet Society. The IAB actively encouraged the formation of the Internet Society, and hopes that the Internet community will give the society its full support. Indeed, as soon as signup became possible, all IAB members paid their dues and became Internet Society members! We anticipate that the IAB will become an integral part of the Internet Society, although the means by which this will be effected are still under study. Like the IETF, the Internet Society is designed to be primarily a grass-roots organization, as free as possible from domination by any single organization or subset of the Internet community. Thus, votes will be given to members, not to organizations. Your participation will make it a success. Westine [Page 3] Internet Monthly Report JUNE 1991 C. NAMING THINGS Periodically, someone asks "what are these protocols called?" The IAB recommends that the term "TCP/IP Protocol Suite" be used for the set of protocols built on top of IP. "The Internet" is the international, interconnected set of datagram networks that once supported only the TCP/IP suite, but is beginning to support the OSI suite as well. "I can't define it, but I know it when I see it". D. INTERNET ARCHITECTURE RETREAT On June 11-13, 1991, the IAB, IESG, and IRSG held a meeting at the San Diego Supercomputer Center, devoted to mapping plans for the future of the Internet architecture. The meeting divided into five groups, on: Routing and Addressing, Multi-Protocol Internet, Security, Traffic Control and State, and Advanced Applications. We think that substantial progress was made, and the results will be summarized at the coming IETF meeting in Atlanta. Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- ANTF held a half-day video conference on June 20th to discuss simulation of very large scale networks.

Bob Braden (Braden@ISI.EDU) Westine [Page 4] Internet Monthly Report JUNE 1991 INTERNET ENGINEERING REPORTS ---------------------------- IETF PROGRESS REPORT (May 01, 1991 to May 31, 1991) Compiled by Phill Gross (IETF Chair) 1) 6 Internet Draft Actions between May 01, 1991 and May 31, 1991 (Revised draft (o), New Draft (+) ) WG I-D Title ------ ------ ---------------------------------------------------- (null) o An Approach to CO/CL Interworking--Part I: Introduction (dhc) + Clarifications and Extensions for the Bootstrap Protocol (bgp) + BGP Protocol Analysis (bgp) + Experience with the BGP Protocol (acct) + Internet Accounting: Background (bridge) o Definitions of Managed Objects for Bridges 2) 6 RFC's Produced between May 01, 1991 and May 31, 1991 (Standard (S), Proposed Standard (PS), Draft Standard (DS), Experimental (E), Informational (I) ) RFC Status WG Title ------- -- -------- ---------------------------------------- RFC1224 E (alertman) Techniques for Managing Asynchronously Generated Alerts RFC1229 E (snmp) Extensions to the Generic-Interface MIB RFC1230 PS (snmp) IEEE 802.4 Token Bus MIB RFC1231 PS (snmp) IEEE 802.5 Token Ring MIB RFC1232 PS (snmp) Definitions of Managed Objects for the DS1 Interface Type RFC1233 PS (snmp) Definitions of Managed Objects for the DS3 Interface Type Standards( 4), Experimental( 2), Informational( ) 3) Security Area Report (Steve Crocker, TIS) The security area within the IETF is responsible for development of security oriented protocols, security review of RFCs, development Westine [Page 5] Internet Monthly Report JUNE 1991 of candidate policies, and review of operational security on the Internet. Much of the work of the security area is performed in coordination with working groups in other areas. The Security Area Advisory Group (SAAG) is a group of security experts which provides both consulting help to other areas and direct management of working groups within the security area. The main bulk of work for the SAAG consists of a set of formal work items. These work items correspond to three types of activities. o Working groups within the IETF Security area. These are marked as "Security." o Working groups in allied organizations that function as part of the IETF Security area. These are marked either "PSRG" for the Privacy and Security Research Group, or "TSIG" for working groups within the Trusted Systems Interoperability Group. o Security relevant developments within working groups in areas other than security. These are marked according to the relevant area, viz., Applications, Internet Services, Management, OSI, Operations, Routing, Standards, or User Services. o Internal SAAG work items. These are topics which do not merit the creation of a formal working group but which do need some level of attention. These are assigned to a SAAG member and followed for one or more SAAG meetings. These are marked as "SAAG." The following is the status of each of the currently open work items. wi001: (Security) SNMP Security -- Keith McCloghrie and James M. Galvin Develop an enhancement to SNMP to support 3 security services: data origin authentication, data integrity and data confidentiality. The Administrative Model document is being coordinated with the Network Management Area. Three documents --- the Administrative Model, the Security Protocols, and the MIB --- are available as internet drafts. Revised documents should be published in July, prior to the next IETF, in preparation for submission to the IESG for consideration as Proposed Standards. Westine [Page 6] Internet Monthly Report JUNE 1991 wi002: (Routing) Router Requirements -- Phil Almquist To identify and resolve security issues as needed by the working group. Mike St. Johns has completed a second security review of the draft. He will be meeting with Phil Almquist during the week of June 3 to finalize the security considerations section. wi003: (Security) Site Security Policy Handbook -- P. Holbrook and J. Reynolds Create a handbook that will help sites develop their own site- specific policies and procedures to deal with computer security problems and their prevention. The comment period closed May 15th. We are in final revision status right now, and we still expect to have this available as an internet draft by 6/1. wi004: (Security) Security Policy -- Richard Pethia Create a document that can guide the creation of security policies for Internet sites. The "Guidelines for the Secure Operation of the Internet" is available as an internet draft. It has been forwarded to the IAB for publication as an informational RFC. wi005: (SAAG) Export of Security Related Implementations -- Vint Cerf Prepare an informational document that summarizes the export control issues. Appropriate points of contact within the various government agencies will also be included. The document will focus on US policy, mentioning others where information is readily available. Vint Cerf has begun writing a document. It is on hold pending changes to export rules to East Europe. wi006: (Security) Common Authentication Technology -- John Linn Provide security services to a range of IETF protocol callers in a manner which insulates those callers from the specifics of underlying cryptographic security mechanisms, enabling modular separation between protocol and security implementation activities. Westine [Page 7] Internet Monthly Report JUNE 1991 The working group and its charter will be announced on the IETF list by June 15. wi007: (SAAG) Password Management -- Jeff Schiller BOF at St. Louis IETF. No progress to report. wi008: (Applications) Telnet Security Services -- Dave Borman To enhance the TELNET protocol to include security services. A specification for authentication within TELNET exists. It has not been discussed within the last month. wi009: (SAAG) IAB Crypto Committee -- Steve Kent and Steve Crocker Create a committee to review crypto related algorithm choices in the Internet; hash algorithms are the first priority. A number of cryptographers have been contacted. Steve Kent and Steve Crocker will contact additional people. wi010: (SAAG) IP Security Option -- Steve Kent Create an IP security option. An internet draft was made available. Comments have been received and Steve Kent is revising the draft. wi011: (TSIG) Commercial IP Security Option -- Ron Sharp Define an IP security option that can be used to pass security information within and between security domains of the commercial, U.S. civilian and non-U.S. communities. A charter has been coordinated and filed. It is waiting for approval. The CIPSO WG is working on a draft specification that is being reviewed by Mike St. Johns. wi012: (PSRG) Privacy Enhanced Mail -- Steve Kent To specify the inclusion of security services in Internet text- based mail messages. The successors to RFC 1113, 1115, and the "FORMS" document (not previously published as an RFC) are available as internet Westine [Page 8] Internet Monthly Report JUNE 1991 drafts. The successor to RFC 1114, the key management infrastructure, should be available as an internet draft in July, prior to the next IETF meeting. It is being delayed in order to accommodate a large number of comments, include the addition of an appendix which specifies the requirements RSADSI will impose on certification authorities under its jurisdiction. wi013: (Applications) Network Printing Protocol -- Glenn Trewitt To support the working group in selecting and integrating security services. Following the March IETF meeting, Glenn Trewitt (Network Printing WG chair) drafted a memo entitled "Adding Security Mechanisms to PAP", reflecting CAT integration plans. John Linn reviewed this memo, and it was subsequently distributed to the NPP WG list. No further actions are currently planned in advance of the July IETF meeting. wi014: (TSIG) Trusted Network File System -- Glover No progress reported. wi015: (OSI) Directory Services -- Steve Kille Include the use of strong authentication in the pilot project. No progress to report. wi016: (SAAG) Network Database Privacy -- Joyce Reynolds and Steve Crocker Steve Crocker and Joyce Reynolds are drafting a proposed statement. wi017: (SAAG) CHRONOS -- ?? The SAAG will request a presentation from the working group at the next IETF as to the scope of their work in preparation for identifying security issues. wi018: (Routing) Router Discovery -- Steve Deering The internet draft document has been reviewed. Although no security services are included in this specification of the protocol, the Security Considerations section accurately describes the security issues. Provision has been included for later inclusion of security services in the protocol. Westine [Page 9] Internet Monthly Report JUNE 1991 ==================================================================== IETF PROGRESS REPORT (Jun 01, 1991 to Jul 01, 1991) Compiled by Phill Gross (IETF Chair) 1) Let me remind everyone that the next IETF meeting will take place in Atlanta on July 29 - May 1 1991. Complete registration and logistics information has already been mailed to the IETF mailing list. A preliminary schedule for working groups meetings have also been mailed to the IETF list. For copies of this information (or for any other question about the upcoming meeting), please mail to ietf-rsvp@nri.reston.va.us. For general information about the IETF, you can send questions to mdavies@nri.reston.va.us. There will be some very important activities at the Atlanta meeting. We will have report from the IAB on their workshop conducted last month to look at future directions for the Internet protocols. We will also discuss an IESG planning activity for future IETF directions. I have asked each IETF Area Director to develop an "Area Plan" to chart activities in their areas. These plans are now being compiled into an "IETF Planning Document", which will be issued as an Internet-Draft for wide comment. It is this document we will be discussing in conjunction with the IAB workshop report. It should be an important session. This is an open technical discussion, and we invite all interested persons to join us in Atlanta. 2) I am pleased to report that we have several new people participating on the IESG. Dave Borman (Cray) has joined the IESG and is forming a new IETF area called Transport Services. This will essentially be a reincarnation of Craig Partidge's previous area, which the exception that we will continue to have User Services as a separate area. Some WGs from both the Applications and Internet Areas. Dave will have more to report on this at the Atlanta meeting. I am also pleased to welcome Philip Almquist aboard as a Co-Area Director of the Internet Area. Noel Chiappa is the current Internet Area Director. THe Internet Area is one of the largest in the IETF, and the addition of Philip will provide some much needed additional support. Finally, I am *very* pleased to welcome Bernhard Stockman of Nordunet and Susan Estrada (CERFnet) as Co-Area Directors of the Operational Requirements Area. I have acted as interim AD for some time now, and I am glad we will finally see this important area get the full-time attention it deserves. Westine [Page 10] Internet Monthly Report JUNE 1991 We will discussions of how the these areas will be organized and managed during the open IESG session in Atlanta. 3) 15 Internet Draft Actions between Jun 01, 1991 and Jul 01, 1991 Posted Revised WG I-D Title ------ ------- ------- ---------------------------------------------- Nov 90 Jun 91 (no wg) FTP-FTAM Gateway Specification Jun 91 New (pppext) Point-to-Point Protocol Extensions for DECnet Phase IV Jun 91 New (decnetiv)DECnet Phase IV MIB Extensions Jun 91 New (cat) Generic Security Service Application Program Interface Jun 91 New (osids) Schema for Information Resource Description in X.500 Jun 91 New (disi) Interim Schema for Network Infrastructure Information in X.500 Jun 91 New (osids) Schema for NIC Profile Information in X.500 Jun 91 New (osids) Interim Directory Tree Structure for Network Infrastructure Information Jun 91 Jun 91 (iplpdn) Discovery and Routing over the SMDS Service Jun 91 New (iplpdn) Management Information Base for Frame Relay Jun 91 Jun 91 (iplpdn) Multiprotocol Interconnect over Frame Relay Networks Jun 91 New (iplpdn) Inverse Address Resolution Protocol Jun 91 New (822ext) Mechanisms for Specifying and Describing the Format of Internet Message Bodies Jun 91 New (none) A User Agent Configuration Mechanism Jun 91 New (netdata) Network Database Westine [Page 11] Internet Monthly Report JUNE 1991 4) 2 RFC's Produced between Jun 01, 1991 and Jul 01, 1991 (Standard (S), Proposed Standard (PS), Draft Standard (DS), Experimental (E), Informational (I) ) RFC Stat WG Published Title ------- -- -------- ---------- ------------------------------------- RFC1238 E (snmp) Jun 91 CLNS MIB -

Holbrook and J. Reynolds Create a handbook that will help sites develop their own site- specific policies and procedures to deal with computer security problems and their prevention. The Site Security Policy Handbook was submitted as an Internet Draft on June 3. The document was title "Security Policy Handbook". There some discussion of the name of the handbook; the title will probably be changed slightly to something like "Site Security Handbook" before the document is released as an RFC. We still have a request in for a plenary slot at the Atlanta IETF. Paul Holbrook has requested a spot early in the week. It is not clear at this point if the plenary slot will talk about the SPWG work as or just the SSPHWG. wi004: (Security) Security Policy -- Richard Pethia Create a document that can guide the creation of security policies for Internet sites. The "Guidelines for the Secure Operation of the Internet" is available as an internet draft. A number of good comments have been received.

Although no security services are included in this specification of the protocol, the Security Considerations section accurately describes the security issues. Provision has been made for later inclusion of security services in the protocol. wi019: (Internet Services) Point-to-Point Protocol Authentication -- S. Knowles To assist the Point-to-Point Protocol (PPP) Extensions Working Group in the enhancement of PPP to include an authentication service. This is a new work item. The latest draft of the protocol has been forwarded to the SAAG for review. Dave Balenson will be providing comments to the working group prior to the Atlanta IETF. Westine [Page 19] Internet Monthly Report JUNE 1991 INTERNET PROJECTS ----------------- BOLT BERANEK AND NEWMAN INC. ---------------------------- Inter-Domain Policy Routing During the month of June 1991, we spent the majority of the time putting together the necessary documents for submitting IDPR as Proposed Standard within the IETF. These documents include an architecture description, a protocol specification, a set of configuration guidelines, and an SNMP MIB. BBN is preparing the first three documents and SAIC is preparing the MIB. Jil Westcott (Westcott@bbn.com) CERFNET ------- CERFnet introduced a new dialup service called DIAL n' CERF Plus. This service will provide customers with a Telebit Netblazer at their site for dialup to the Internet. This will simplify their dialup process and make it easy for multiple users to access the network with minimal training. Three new dedicated sites will be installed in July.

The primary topic of discussion was the FY 91-92 Business Plan. The following new officers were elected: Peter Roll (Northwestern University) - Chair; Arthur Lindeman (IndianaUniversity) Vice Chair; Lee Shope (University of Iowa) - Secretary. On June 6-7 the CICNet Technical Board met at Indiana University Bloomington campus. The meeting was attended by the technical support staff from the CICNet member institutions and was highlighted by a Westine [Page 20] Internet Monthly Report JUNE 1991 presentation on SMDS given by Ameritech. CICNet President Michael Staman gave a presentation on using Toolbook as an authoring tool at the annual IBM ACIS conference in Dallas. Mike also attended a meeting of the National Board for Professional Teaching Standards in St. Louis, an organization dedicated to improving the quality of teaching in the K-12 sector. CICNet Assistant Director John Hankins gave a presentation on CICNet activities to a national meeting of law school computer support staff held at the Illinois Institute of Technology Kent College of Law. John made a similar presentation to the SURF Foundation, an organization in the Netherlands responsible for information technology coordination and evaluation, during a visit by the SURF Foundation staff to Ann Arbor. by John L Hankins CORNELL ------- Gatedaemon Project We participated in the OSPF Interoperability tests at FTP Software the first week in June. Gated interoperated successfully with several NBMA OSPF implementations. Most of the rest of the month was spent merging the changes Rob Coltun made to his OSPF at the Interoperability testing and cleaning up gated enough for an alpha OSPF release, which was made available on June 26th. An OSPF MIB query tool is being written in the ISODE SNMP modified gawk and tested against Proteon's OSPF MIB implementation. It has only been tested as far as Proteon has implemented. Dennis Ferguson from the University of Toronto visited for a week to restructure his BGP v2/3 implementation and integrate it into the latest gated development sources. Scott Brim (swb@nr-tech.cit.cornell.edu) CSUNET ------ Twenty-two Stratacom IPX T-1 multiplexors were purchased and delivered for use at the twenty California State Universities across California. These Fast-Packet(tm) MUXes are frame-relay Westine [Page 21] Internet Monthly Report JUNE 1991 capable and interoperate with CSUnet's Cisco Systems routers using frame-relay. CSUnet plans to support IP, DECnet, and AppleTalk using the frame-relay technology. On June 3, the San Diego and Fullerton campuses were installed along with the Los Alamitos Network Operations Center (SWRL). The cisco routers at those sites have been connected to form a frame- relay network.CSUnet is using the IPX/16 and IPX/32 models of the StrataCom MUXes. Testing has been on-going throughout the month to ensure interoperability between Cisco and Stratacom. Mike Marcinkevicz (mike_marcinkevicz@qmbridge.calstate.edu) ISI --- GIGABIT NETWORKING ATOMIC Work has begun on implementing the ATOMIC network host interface software within the 4.0 SUN UNIX Kernel. Greg Finn INFRASTRUCTURE Joyce Reynolds attended the IAB/IESG/IRSG "retreat" held in San Diego, the week of June 10th. Ann Westine visited NRI in Reston, VA, June 19-23 to install the IETF mailing list there. Six RFCs were published this month. RFC 1234: Provan, D., "Tunneling IPX Traffic Through IP Networks" Novell, Inc., June 1991. RFC 1235: Ioannidis, J., and G. Maguire, Jr., "The Coherent File Distribution Protocol", Columbia University, June 1991. RFC 1236: Morales, L., and P. Hasse, "IP to X.121 Address Mapping for DDN", USAISEC, June 1991.

Haggerty (Wang) K. Dobbins, (Cabletron Systems, Inc.,) "OSI Connectionless Transport Services on top of UDP, Version: 1", June 1991. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING This month the first real teleconference using the ST-II version of the Voice Terminal (VT) program, the packet audio component of our conferencing system, was held among five sites on DARTnet. Also this month we successfully tested packet video over DARTnet between ISI and BBN. For networks with limited bandwidth, we have now implemented sender-selected floor control for packet video conferences. Normally, video streams from all participants are sent to all other sites. On receipt, each individual site decides which video stream(s) to display. In scenarios where n-way traffic would exceed bandwidth limits, only one site is selected to send video at a time. A chairperson or moderator is used to decide which site distributes its video data and which other ones refrain from sending video output. Eve Schooler, Steve Casner (schooler@ISI.EDU, casner@ISI.EDU) 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 for June, 1991 is 99.71%. The traffic for May was 1,814,315,622 (combined in plus out) packets. Four highest contributors were Rutgers University (13.68%), Princeton University (12.13%), UPENN (5.23%), and Yale (5.11%). Installation of the cisco CSC-3 processors for the T1 backbone upgrade continues. Installation of the T3 node is in progress. Matsushita Information Technology Laboratory (T1, Princeton,NJ), National University of Singapore (64kbps), and the University of Connecticut (56kbps, Storrs, CT) became operational in June. Westine [Page 23] Internet Monthly Report JUNE 1991 Network Security, the second in a series of JvNCnet Symposiums, took place on Thursday, June 27, 1991 at Princeton University. Because today's economy is significantly information-driven and more people have integrated computing and computer networks, such as Internet, into their daily work, research, and scholarly efforts, JvNCnet decided to bring together a prominent panel to discuss a variety of security issues with respect to the Internet community. Attention was also paid to requirements of making a network connection secure. In addition, a member of JvNCnet described JvNCnet's security protocols. The following individuals, who comprised the panel, detailed these subjects. Stephen Crocker, TIS Internet security Barbara Fraser, CERT CERT's role in Internet security Ted Ts'o, MIT Kerberos William Cheswick, AT&T Bell Labs AT&T's secure gateway Vikas Aggarwal, JvNCnet JvNCnet's security approach JvNCnet plans to continue sponsoring symposiums that bring to the forefront issues, advanced technologies and applications for networking technologies as well as training sessions, introductory and advanced. It recognizes the need toprovide a diverse educational program for its members, users, and anyone interested in networking. For further symposium information, please send inquiries to "nisc@jvnc.net." The JvNCnet Regional Meeting followed the symposium on Friday, June 28. Sergio Heker, during his short briefing, happily announced a 100% increase in membership since JvNCnet became part of Princeton University nine months ago. He also announced the imminent release of the JvNCnet Network Operations CenterOn-Line (NOCOL) network monitoring software package to the Internet community without charge. For more NOCOL details, send email to "nocol- info@jvnc.net." Two parallel sessions, which shaped the design of the regional meeting, fostered and enhanced discourse among members and with JvNCnet. Westine [Page 24] Internet Monthly Report JUNE 1991 Five different groups concentrated on: *Engineering issues and network performance and characterization *Members' needs of "Network Information On-Line (NICOL), JvNCnet's menu-driven information resource and the TCP/Mail Chapter of the JvNCnet Member Handbook/Introduction Guide (user manual). *X.500 directory services *Operational troubleshooting *Dialin'Tiger Users' group Interaction supplied lively exchange and resulted in necessary feedback. Three members described their Internet-accessible services. Mr. Todd Vander Does explained the e-MATH service developed at the American Mathematical Society with partial NSF funding.. Telnet e-math.ams.com. Login and password are e-math. Electronic inquiries: support@e-math.ams.com. Ms. Stephanie Supplee and Mr. Alan Huber talked about the LEXIS/NEXIS services (legal database/business information) of Mead Data Central. Mr. Anthony Abbott detailed the developing Meckler Corp./JvNCnet NICOL project for viewing and accessing all Meckler's publications. Dr. Leslie Michelson's Site Profile of the University of Medicine and Dentistry of New Jersey nicely completed the meeting. The next regional meeting will take place in about four months. by Rochelle Hammer LOS NETTOS ---------- JPL is our last member site to have their remote console access kit installed. It provides dial access to the console of the cisco, the Datatel CSU/DSUs, and to power cycling the equipment. Caltech and JPL were retrofitted with cisco AUX ports which are used to provide telnet access to the same functions when the network is not partitioned. OSPF testing is in progress. Walt Prue (Prue@ISI.EDU) Westine [Page 25] Internet Monthly Report JUNE 1991 MITRE Corporation ----------------- Shari Galitzer visited Merit's NOC in Ann Arbor with a group from DCA. Forrest Palmer and Kevin Thompson participated in the Army and Air Force Secure Tactical Data Network Demonstration held at Ft Gordon, 24-28 June 1991. Forrest demonstrated the capabilities of a commercial SNMP network management package to monitor routers and host systems on LANs and radio communication links. We hope to retain some functional capabilities for demonstrating network management in a strategic- tactical internetworking environment for our year-end demo. MITRE developed methods of collecting data at the transport layer in the network and analyzing it to provide integrated information on both the user-level performance and the undelying network conditions. These methodologies and tools were successfully used during the Integrated Tactical Demonstration Network (ITDN) in September 1989 (Allison Mankin's IEEE MILCOM paper describes this work). Kevin executed tests with TCP traffic over tactical links, yielding measures of access time, round-trip delay, throughput, burst power, and loss rates. These measurements were folded back into the experiments planned for Forward Error Correction techniques. Allison has taken delivery of her Sparcstation-2's. Her network performance visualization software is being moved to the Sparc and X, from the less portable PIXAR platform. Walt Lazear presented a briefing on router technology to the DCEC RDT&E Technology Seminar on 20 June. Walt also participated in testing to bring ESNET into the OSI routing fold. CLNP now is routed through NSFNET, through some regionals (like Michnet and Alternet), and through the FIX to ESNET. Walt Lazear (lazear@gateway.mitre.org) Westine [Page 26] Internet Monthly Report JUNE 1991 NEARNET ------- NEARnet has grown to 80 members. ESNET (DECNET) is being routed over NEARnet to Brown University, enabling them to use one connection for both TCP/IP and DECNET connectivity. Network operations continues to be stable. The transition to the T3 network is progressing. by John Rugo NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Karen Roubicek participated in the Coalition for Network Information (CNI) Directory Working Group in Palo Alto, California, and attended an Open Meeting on the Interim-NREN Network Information Services in Washington, DC. The NNSC has updated the network provider referral list. The new list is available through the NSFNET portion of the Info-Server. To receive this list send a message to: info-server@nnsc.nsf.net, in the body of the message type: Request: nsfnet Topic: referral-list This request will automatically send you the referral-list file. The NNSC distributed additions to Chapters 3 of the Internet Resource Guide. Corinne Carroll NSF BACKBONE (Merit) ------------------- Total traffic on the NSFNET T1 and T3 infrastructures measured 7,726,207,578 inbound packets. This figure represents all inbound traffic from the 16 NSFNET end nodes. NSFNET T1 infrastructure inbound traffic totaled 7,156,101,602 packets during June, 1991. This total includes packet traffic entering the T1 network from the T3 network. As of June 28th, 2982 networks are announced to the T1 NSFNET; of this total, 989 are Westine [Page 27] Internet Monthly Report JUNE 1991 foreign nets. NSFNET T3 infrastructure inbound traffic totaled 1,612,595,367 packets during June, 1991. This total includes packet traffic entering the T3 network from the T1 network. Networks announced to the T3 NSFNET numbered 583 nets at the end of June. Testing was completed for a second point of interconnection between the T1 and T3 infrastructures at San Diego during June. This interconnect will route production traffic as of July 2. T1 and T3 infrastructures are also interconnected at Ann Arbor. Phase 1 of the T3 NSFNET deployment was accomplished on June 24th as the node at Argonne began accepting production traffic. Phase 2 of the T3 expansion includes the addition of core nodes and DS3s to support the planned E-NSSs at the remaining T1 nodes. Core nodes have been added at Hartford, New York and Greensboro on the east coast; core nodes in St. Louis, Denver and Seattle will be added in mid-July. The installation of T3 nodes at the remaining T1 nodes is tentavitely planned for mid-July through mid-August. Guests at the Merit/NSFNET Network Operations Center included the Netherlands Scientific Technical Board: W.J. Keller, director of the Netherlands Bureau of Statistics; W. Loeve, director of the informatics division of the National Aerospace Laboratory; C.C.M. Hendriks, director of informatics of the Rotterdam Polytechnic School; J.C.M. Pietersen, project manager of the SURF Foundation; and A.D. van Ingen Schenau, secretary of the Scientific Technical Board. Their agenda included an overview of the NSFNET Project, a demonstration of the University of Michigan Institutional File System, a tour of the language multimedia lab Project Flame, and the Harlan Hatcher Library. Manuel Ludevid, Executive Director of the International Social Science Council Human Dimensions of Global Environmental Change Programme, Barcelona, Spain, was a visitor to the University of Michigan's Institute for Social Research. An overview and discussion of the NSFNET project was part of his tour of the University. Jessica Yu and Elise Gerich of the Merit Internet Engineering group were its representatives at the June meeting of the FEPG at Moffett Field. Gerich also participated in the IAB retreat held in San Diego, CA. Sue Hares of Merit Internet Engineering attended the InterOp '91 OSI Demonstration planning meeting. NSFNET is encouraging regional and national networks currently passing CLNP traffic across the NSFNET infrastructures to join in an OSI demonstration for InterOp '91. Further information is available from Hares (skh@merit.edu). Hares also participated in the Boston ANSI X3 S3.3 committee meeting, continuing work on IDRP and the implementation of OSI in NSFNET. Westine [Page 28] Internet Monthly Report JUNE 1991 iNET '91, the international networking conference, was held in Copenhagen, Denmark, June 18-20. The NSFNET project was represented by both Eric Aupperle, President, Merit Network, Inc., and Susan Calcari, Merit/NSFNET Information Services. Aupperle spoke on the "NSFNET - Current Performance and Short-term Directions," while Calcari gave a presentation on "Education over the International Internet." Aupperle subsequently traveled to the Technical University of Berlin (Germany), where he addressed an audience on "Merit's Networking Experiences--Global, Statewide and on Campus." Participating on the Social Sciences panel, Calcari gave an NSFNET update at the IBM Academic Computing Conference (ACIS) in Dallas, TX. Glee Harrah Cady, Manager of Merit/NSFNET Information Services, and Laura Kelleher, Merit/NSFNET Information Services, were its representatives at "Developing a Framework for Network Directories and Related Services," the Coalition for Networked Information (CNI) meeting at Stanford University. Cady facilitated a discussion of users as resources and Kelleher gave a presentation on the MichNet approach to collecting network information, which focuses on the user not the resource. Cady also gave an NSFNET overview and update at the Research Libraries Group (RLG) offices. Kelleher represented Merit/NSFNET at Networking '91, the CA*net/Netnorth/CDNnet Annual Conference, in Kingston, Ontario, and presented an NSFNET update. Jo Ann Ward (jward@merit.edu) NDRE and NTA-RD --------------- NDRE and NTA-RD have nothing to report this month. Anton B. Leere PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- Stephen Cunningham has taken over the position of Network Coordinator and will be the first line of contact for network related matters involving the Pittsburgh Supercomputing Center. This position was previously held by Gregory Dobrich who has moved on to work with SURAnet. We have completed testing of our new T3 ENSS and moved it into production use. The final network design consists of a two tiered network hierarchy, consisting of a primary production path and a secondary backup network path. The primary path, the new high Westine [Page 29] Internet Monthly Report JUNE 1991 speed network, contains the T3 (45 Mbps) connection to the NSFnet, an internal FDDI (100 Mpbs) network between the Mellon Institute and the Westinghouse Machine room and finally, a Low Speed Channel (100 Mbps) to the Cray. The secondary path, PSC's previous production path, consists of the T1 (1.5 Mbps) to the NSFnet, two internal T1 (1.5 Mbps) connections between the Mellon Institute and the WEC Machine room and an ethernet (10 Mbps) connection to the Cray. PSC's new network should benefit all PSC Users. First, the two tier hierarchy provides PSC with a very robust network with no single point of failure. Second, users will see a significant drop in delay when traversing the T3 instead of the T1 backbone. For example, the average delay across the T3 between PSC and MERIT is 19 msec, while across the T1 it is 60 msec. Users whose sites do not yet have access to the T3 backbone will also see a drop in delay due to improved internal connectivity. For example, the average delay over the old production network was 20 msec while it is just 4 msec over the new high speed network. Stephen Cunningham (CUNNINGHAM@B.PSC.EDU) PREPNET ------- During June, two new hubs became operational. We installed cisco-based hubs in Harrisburg and in State College. We also had four organizations join PREPnet. Muhlenberg College will be connected to the Allentown hub at 56Kbps, Lebanon Valley College will be connected to the Harrisburg hub at 9.6Kbps, ICDD (International Centre for Defraction Data) will be connected to the terminal server in Philadelphia via a 9.6Kbps leased line, and Juniata College will be connected to the State College hub at 56Kbps. PREPnet and the PA Dept. of Education sponsored a K-12 seminar on June 12th. The purpose of this seminar was to gather together people working on K-12 projects so they could talk with each other. We had thirty people attend the seminar. The attendees were very enthusiastic. We are making plans for future meetings. PREPnet NIC (prepnet+@andrew.cmu.edu) Westine [Page 30] Internet Monthly Report JUNE 1991 SAIC ----- Recent Activities: The first step in the gated port has been completed. The IDPR prototype now runs as a single process. The first cut at making IDPR a gated task is underway. During the past month, Ken Carlberg from SAIC and Mark Sleeper from Sparta prepared a draft MIB for policy terms for IDPR. They have done some testing of this MIB using the University of Wisc. CMOT code. An initial version of the full IDPR MIB which includes the policy term MIB as an appendix has been completed and made available to the IDPR WG in preparation for the July IETF meeting. Planned activies: Completion of initial gated integration is our highest priority. Additional code cleaning and optimization will take some time because of the inefficiencies introduced by the old multi-process implementation. A design of a new common database for all IDPR modules will be essential as the current implementation has a lot of per-module redundancy. We are investigating the possibility of an IDPR demo at the upcoming IETF. Woody Woodburn (woody@sparta.com) SRI NIC ------- Because the supply of Class B numbers is dwindling due to the growing number of requests for these numbers, the NIC Internet registry has imposed more stringent requirements for obtaining these numbers. Organizations that want to obtain large groups of Class B numbers (five or more) will be required to furnish the registry with a detailed rationale for their requests, and in some cases will be asked to accept alternative allocations of Class C numbers. The cumulative total of all IP numbers now assigned is 30,146. See the table below for a breakdown by month. There are now a total of 1,290 Autonomous System numbers (ASNs) assigned. There are currently a total of 2,298 domains registered. This includes the root domain, 63 top-level domains, 2,172 second-level domains, and 62 third-level MIL subdomains.

Speakers from the Computer Emergency Response Team (CERT), the Coalition for Networked Information (CNI), the National Agricultural Library, The Texas Education Agency, Advanced Network & Services, Inc. (ANS), Texas A&M University, VideoTelecom Corp., EDS, Thinking Machines Corporation, and The State of Texas House of Representatives will make presentations about telecommunication and networking issues in higher education. Registration, agenda and travel information is available via anonymous ftp to host ftp.utexas.edu, directory "pub/conference", file "information.full". Tracy LaQuey Parker Westine [Page 32] Internet Monthly Report JUNE 1991 UCL ---- Jon Crowcroft and Steve Wilbur attended the INET'91 Conference in Copenhagen, and gave papers on the UK-US Traffic Patterns (available for anonymous ftp from docs/inet.ps on cs.ucl.ac.uk) and workstation videoconferencing. There was a video conference between London University Librarians and MIT librarians (our first international "naive" users). The T20 Gateway replacement for the ULCC butterfly and a video conference to discuss progress on UK-US Interconnection are happening as I write. A meeting of the "Shoestring" group was held at UCL to discuss progress on the IP pilot in the UK. Backbone routers (ciscos) are delivered and now Phase II (introduction of more sites) is starting. The routing architecture is being hammered out. Sites/Campus nets are starting to appear properly in the DNS (e.g. Cambridge University). Discussions are underway for 34Mbps leased lines for at least around London very soon. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Packet-loss rates from campus to the College Park NSFnet NSS have reached the six-percent level. We are working with SURA people to resolve this problem. 2. Work continues on constructing SBus interfaces for SPARCstations and high-speed crossbar switches for our Highball project. Work also continues on algorithm simulation and system robustness. Partly due to recent events, we have become keenly interested in system fault-tolerant principles. 3. A substantial redesign is in progress on network synchronization for DARTnet. We hope to improve reliable timekeeping accuracy to the submillisecond regime. 4. We have obtained audio, video and interface gear to support real-time conferencing. We plan to use this for DARTnet experiments and general teleconferencing. Dave Mills (Mills@UDEL.EDU) Westine [Page 33] Internet Monthly Report JUNE 1991 WISCNET ------- A WiscNet descriptive flyer and membership memo of understanding were finalized and distributed to prospective new members. Michael Dorl (dorl@macc.wisc.edu) Westine [Page 34] Internet Monthly Report JUNE 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 o IETF DISI Working Group [X] o Field Operational X.500 Project - ISI - Merit - PSI - SRI o National Institute of Standards and Technology [X] o North American Directory Forum [X] 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) [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 IETF OSIDS WORKING GROUP ------------------------ The OSI-DS documents are now numbered as a document series. Two documents were released: OSI-DS 16: "Schema for NIC Profile information in X.500" Chris Weider & Mark Knopper June 1991 Abstract: The authors wish to put put up a readily accessible, distributed Directory of Network Information Centers, or NICs. This paper discusses the schema used to hold the NIC Profiles, as well as the DIT structure necessary for this information. Westine [Page 35] Internet Monthly Report JUNE 1991 OSI-DS 17: "Schema for Information Resource Description in X.500" Chris Weider May 1991 Abstract: The authors are interested in allowing distributed access and updating for Information Resource Description information to users of the Internet. This paper discusses the schema used to hold the Information Resource Description information. The new attributes are taken from the US-MARC fields, and subfields, with the mapping described in the text. Preparation is underway for the next WG meeting at the IETF in Atlanta. Steve Hardcastle-Kille (s.kille@cs.ucl.ac.uk) 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 July 9 FOX phone conference, which included participants from all of the FOX contractors. FOX participants will meet sometime during the Atlanta IETF. Steve Hotz (hotz@ISI.EDU) MERIT ----- Some of the Merit activities related to X.500 and Directories which took place during June: o Work on schema definitions for NIC Profiles and Internet Online Resources, including internet drafts outlining that work. o Met with John Clement of Educom about directory of K-12 people and resources. Started schema definitions for those as well. Westine [Page 36] Internet Monthly Report JUNE 1991 o Began work to implement e-mail based query and updating system for K-12 for Educom. This will be a prototype for a later production system. o Received new workstation to use as DSA for FOX project activities. Mark Knopper (mak@merit.edu) PSI --- A new X.500-based application, "x5ftp", was released for alpha testing by FOX project partners. "x5ftp" is an X.500-based application that allows one to search a portion of the Directory for references to documents. The application then allows the selective retrieval of documents by anonymous ftp. "X5ftp" provides a command-shell interface to a complete X.500 DUA that is specially tailored for document retrieval. A paper which discusses the role of X.500 in information retrieval was written. This paper, published by PSI as Technical Report 91-06-25, is available for anonymous ftp from uu.psi.com [136.161.128.3] in wp/nir.ms (nroff/troff version, ms macros) wp/ps/nir.ps (Postscript version) and wp/nir.txt (text version). Wengyik Yeong (yeongw@psi.com) SRI --- We observed that the Northern Swift Fox DSA was core dumping given an inconsistent collection of circumstances. The problems were traced to a lack of swap space on the DSA's host. The system was reconfigured to increase swap space by approximately 25%. No similar problems have been observed. SRI began an investigation of options for providing a user interface to support access to the WHOIS information now stored in X.500. The decision as to a course of action is forthcoming in a subsequent report. A low-level investigation of problems with NIST's Custos 0.1.1 continued. Although original suspicions centered around ISODE version incompatibilities (Custos 0.1.1 was developed with ISODE 6.0 while SRI is running version 6.8), restoring ISODE 6.0 at Westine [Page 37] Internet Monthly Report JUNE 1991 SRI and subsequent recompilation of Custos 0.1.1 yielded no progress. NIST and SRI will continue their investigation, focusing on possible configuration differences. Work on the DISI X.500 implementation catalog continued. Ruth Lang and Russ Wright (LBL) have written a majority of the supporting sections that will accompany the implementation descriptions. A draft list of cross-reference keywords has been selected and applied to the descriptions. A formatted version of the document (Internet-Draft) will be made available before the July IETF meeting. Ruth Lang (rlang@nisc.sri.com) OIW --- The OSI Implementor's Workshop (OIW) Directory Service SIG met during June 10-13, 1991. There were about 20 attendees representing 15 vendors and users. It was a very productive meeting and the SIG generated the following outputs: o Access Control and Replication: The SIG generated draft working agreements on Access Control and Replication based on PDAMs and CD. For Access Control, the SIG created a table for error situations and error actions. For Replication, the SIG generated the DSA Replication Conformance and Recommended Practice sections. These agreements are expected to be stable by the end of 1991 when the standards reach DAM and DIS at the end of October, 1991. o Distributed Operations: The SIG generated draft working agreements on Distributed Operations based on the EWOS profile. These agreements do not include any extension work being developed in the standard body. o APDU size limit: The SIG agreed to change Result APDU size limit from 32K to 256K in order to align with the EWOS profile. This limit will only affect DSAs involved in distributed operations. This modification is expected to affect the Stable Agreements. Westine [Page 38] Internet Monthly Report JUNE 1991 o Pragmatic Constraints: The SIG agreed to change ub-postal-string for the Postal Address attribute syntax from 30 to 60 characters in order to accommodate many existing postal addresses. This change is expected to be made against the Stable Agreements at the next meeting. The SIG sent liaison letters to inform this change and to investigate if this change causes any problems to current Directory user groups. o Guideline on AE Title Use: Informative text was generated in order to guide applications making use of the AE Title field to access application Entity Objects in the Directory. Youbong Weon-Yoon (youbong@arch2.att.com) PARADISE -------- The public access "simple-to-use" PARADISE DUA is available for sampling on one of the project machines; use "telnet 128.86.8.56" and enter "dua" at the login prompt. Comments welcomed to the list Paradise INTerfaceS . The PARADISE packaged DSA and DUA should be available later this month and will be based on ISODE 7.0 which is due for release in mid-July. Interoperability tests are proceeding with the French pilot; the presentation level difficulty has been resolved and the twelve French organizations represented below c=FR are now visible. The QUIPU/PIZARRO discussion has some months to run yet. Inquiries about PIZARRO may be directed to: Paul-Andre Pays . Specific questions concerning the interoperability testing may be directed to: Paradise inteROPERability . David Goodman (d.goodman@cs.ucl.ac.uk) PARADISE Project Manager PSI DARPA/NNT X.500 Project --------------------------- Beta testing was performed on ISODE beta-release 6.9. Experimental versions of existing DSA and DUA software were tested. Testing was also performed to ensure that version 6.9 is backwards-compatible Westine [Page 39] Internet Monthly Report JUNE 1991 with version 6.8. Effort was expended in the past month to increase the reliability of operational X.500 service. To this end: o Watchdog scripts that ensure that processes related to the provision of X.500 service continue to run were written and installed. These scripts will be further enhanced in the future to detect more error conditions that cause denial of service. o Some shuffling of DSA functionality among machines was performed to better distribute the demands placed on various machines by the X.500 service. o An enhanced version of the ISODE software was installed on all machines to fix version skew problems and further enhance reliability. o A systematic schedule of monitoring the reliability of all machines that contribute to X.500 service was begun. Testing was performed, using some of the data in the "o=Performance Systems International" subtree, in preparation for alignment with the COSINE/Internet Naming Architecture. Final testing of a beta version of a White Pages front-end for PC/MSDOS that is layered over FTP Inc.'s PC/TCP kernel is almost completed. Anonymous FTP release of the binary is slated for the 1st week of July. Wengyik Yeong (yeongw@psi.com) PSI WHITE PAGES PILOT PROJECT ----------------------------- As of June 26, 1991, there are 76 organizations participating in the White Pages in the United States of America. New organizations added this past month are: Cornell University The practice of pruning non-responsive DSAs from the c=US arc has been temporarily suspended due to a change in people supporting the White Pages Manager function. Pruning will begin again next month.

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 0016lj1bt.net.cn
