The Internet Engineering Steering Group (IESG) joined the second day of the meeting. A. INTERNET NUMBER REGISTRATION AND CONNECTED STATUS At this meeting, the IAB developed recommendations to the Federal Networking Council (FNC) on the procedures for registration of Internet network and autonomous system numbers, and concerning the notion of "connected status". These recommendations, which have been published in RFC-1174, were motivated by the increasing internationalization of the Internet. The IAB gratefully acknowledges the efforts of Elise Gerich of MERIT, who prepared early drafts of these recommendations for our consideration. Essentially, the IAB recommended that authority to assign IP network and autonomous system numbers be distributed on an international basis. A central registry (Internet Registry) would continue to allocate blocks of numbers, to avoid any duplication, but actual registration and assignment of numbers would be accomplished by delegated registries. The details of procedures, particularly the nomination of delegated registries, remain to be fully specified. The second recommendation concerned "connected status." The IAB recommended that this concept be retired, and that all networks which have been assigned Internet numbers be entered into the Domain Name System database(s) regardless of the status of their physical connectivity. In addition, for each network, a statement describing the nature of the traffic this network would inject into the Internet should be collected and stored by the Internet Registry and made available to all interested parties. This information would be used by network managers and operators to configure routing controls to accept or reject routes from networks, based on the type of traffic each network sends. The Federal Networking Council has responded positively to these suggestions and is now considering various means to implement them. B. ANSI STANDARDIZATION Several members of the IAB were also in attendance at an ANSI Westine [Page 3]  Internet Monthly Report July 1990 X3S3.3 meeting held on June 27 at Data General Corporation. The question of introducing the core TCP/IP protocols (IP,ICMP,UDP,TCP) into ANSI standardization was discussed at length. At the conclusion of the meeting, the proposal for introduction of the protocols was tabled, pending the formation of a joint IAB/ANSI working party to consider all of the ramifications that such a move might have on both ANSI and IAB procedures and prerogatives. The IAB considers it essential, for example, that any changes to these core protocols be subject to the same rigorous treatment that any Internet Protocol receives. In particular, implementation, testing and the availability of public domain implementations lie at the heart of the Internet Protocol standardization process but are largely outside the ANSI process. In the usual course of events within the ANSI environment, the introduction of a protocol for ANSI standardization transfers to ANSI all future authority for further evolution of the protocol. The IAB proposed a modus operandi which would leave the basic standardization activity within the Internet community, including resolution of any objections to standardization arising during ANSI balloting. Since this is not fully consistent with the ANSI rules as we now understand them, the matter requires further examination. C. RARE NETWORKSHOP The IAB agreed to participate in the planning of the RARE Networkshop now scheduled for May, 1991 in Blois, France. D. STANDARDS ACTIONS Following IESG recommendation, the IAB designated the Point-to- Point Protocol (PPP) Initial Configuration Options as a Proposed Standard, and it was subsequently published in RFC-1172. The base PPP specification was advanced to Draft Standard, in May and republished with minor updates as RFC-1171. The Simple File Transfer Protocol (SFTP, RFC-913) and the Resource Location Protocol (RFC-887) were moved from Proposed Standard to Experimental. These protocols, which had been labelled Proposed prior to last year's tightening of the Internet standards process, are not currently in the Internet standards track.

INTERNET ENGINEERING REPORTS ---------------------------- 1. The IETF met at the University of British Columbia in Vacouver on July 31- August 3rd. The meeting was hosted by John Demco. This meeting had numerous firsts. It was the first international IETF meeting. It was also the largest to date, with approximately 300 attendees. Approximately 38 of the current 45 working groups met in 49 separate sessions. Westine [Page 5]  Internet Monthly Report July 1990 Many thanks go to John Demco and Marilyn Martin (UBC) for hosting and helping to plan such a large and diverse meeting. 2. We were also very pleased to have the Privacy and Security Research Group meet with the IETF in Vancouver. In addition to conducting its own business, the PSRG met in joint session with several security related WGs (eg, Site Security Policy Handbook WG, SNMP Authentication WG). This interaction was very productive. Further, such interaction with the IRTF would prove to be a quite beneficial to IETF efforts. 3. We were especially pleased to have a delegation from the European networking association RARE at IETF. Eric Huizer (Surfnet, Netherlands), Ruediger Volk (RIPE, Dortmund Univ), Fernando Liello (Italy), and Olivier Martin (CERN, Switzerland). Eric and Ruediger gave a presentation on networking activities in Europe. The Federal Engineering Planning Group of the FNC met in joint session with the RARE delegation. 4. The ANSI X3S3.3 group also took the opportunity to meet in Vancouver. There is a growing amount of joint interest between IETF and relevant ASNI groups (particularly, X3S3.3 which focuses on the tranport and network layer of the OSI model). We have tentatively agreed with X3S3.3 that we will attempt to schedule meetings during the same location and date whenever it is convenient to both groups to do so. The next such occasion will be in Boulder Colorado in December. 5. The IETF meeting was very full and productive. The final meeting agenda is given below. Full reports from the IETF area directors will be in next month's Internet report. Until then, a brief list of highlights include: - An excellent report on CA*net, the Canadian national network, by Dennis Ferguson (U. Toronto). - Review of a draft proposal for IP over SMDS. - A decision to draft a Link Layer Requirements document separate from the Router Requirements document. There was also a proposal to consolidate all IP specific issues into a separate document for the Router Requirements (and perhaps future editions of Host Requirements) to reference. These new efforts would continue to be an initiative of the RR WG. - Near closure by the Router Discovery WG. - Reorganization of the PDN Routing Wg to include other public networks besides X.25 (eg, SMDS) - Discussions within the Network Joint Monitoring WG for common monitoring and report formats. We also discussed how the IETF Operations area could most effectively be organized and utilized. Westine [Page 6]  Internet Monthly Report July 1990 - Announcement of the IAB recommendation, and the FNC agerement, to eliminate the notion of "connected status" for NIC assigned network numbers. With the FNC accepting this recommendation, MERIT will anounce how this will affect their policy for registering networks in their policy routing database. 6. The next IETF meeting is scheduled for Dec 4-7 in Boulder Colorado. That meeting will be jointly hosted by Carol Ward (Univ. Colorado) and Don Morris (NCAR). 7.

BOLT BERANEK AND NEWMAN INC. ---------------------------- INTERNET O&M / ICBNET INFRASTRUCTURE Delays in the installation of power and T1 circuit facilities within the NASA Ames Research Center, required in support of the TWBNet connection to the FIX-West ethernet, have prevented the scheduled end of May completion of that connection. With the termination of the last segments of the ARPANET on June 1st, this delay has resulted in a temporary inability to route traffic directly between the TWBNet/ICBNet and other US national backbone networks. (Such routing was previously provided to the TWBNet/ICBNet via ARPANET-based connections to the DCA Mailbridges.) In response to this situation, BBN has implemented interim global Internet connectivity for DARPA's internal networks via a temporary path through NRL and SURANet to the NSFNet backbone, and is currently implementing similar temporary connectivity for European ICBNet sites though BBN and NEARnet. The FIX-West TWBNet Butterfly Gateway is currently installed at Ames. The TWBNet to FIX-West connection will be completed, allowing global TWBNet/ICBNet connectivity via direct routing exchange at the FIX, pending the completion of the T1 circuit linking the gateway to the Los Angeles TWBNet packet switch. This is currently scheduled for mid-July. The 64 Kbps circuit connecting STC (The Hague, Netherlands) to WPC (West Germany) was completed and released by the PTTs. Installation of the WPC Butterfly Gateway is scheduled for the first week of July. TCP-TP4 PROTOCOL TRANSLATION We completed the integration on sun workstation of test environment. Test scripts run through Estelle code for protocol translation to demonstrate TCP and TP4 opening sequences. Testing of the interface code is being done to be sure that it handles the Westine [Page 11]  Internet Monthly Report July 1990 full set of packets for both TCP and TP4. Implementation of live network interfaces has begun, on Sun system for TCP/IP and for ISO/TP4 over X.25. Some of the ISODE applications have been brought up on local machines to use for comparison and for live testing of the transport protocol translation. INTER-DOMAIN POLICY ROUTING In June Helen Bowns of BBN along with the USC team of implementors have made quite a bit of progress on Version 1 of the IDPR protocols. The software architecture - modules and interfaces as well as intra-kernel and extra-kernel functionality have been designed. Helen is very close to completing the routing update protocol. Lee Breslau at USC is working on the route synthesis procedure and Gene Tsudik at USC is working on the path setup protocol and encapsulation. The software design of the virtual gateway protocol has not yet been started, but this is the simplest of all IDPR protocols. Implementation of the version 1 IDPR protocols is proceeding smoothly and on schedule. In mid July, SAIC offered to join with BBN and USC in a joint implementation effort. As BBN and USC have the version 1 software well in hand by this time, SAIC will for the most part work on functionality beyond version 1, including how to handle route servers and configuration servers that exist separately from policy gateways. SAIC will also write an extra- kernel implementation of the encapsulation mechanism, which will be helpful in software debugging. We expect to get get out a new version of the architecture and the protocol specification; a new version of both out by early August. Some members of ORWG participated in an inter-domain routing workshop at MIT to discuss the future direction of inter-domain routing. TERRESTRIAL WIDEBAND AND ST/IP GATEWAY During June, the ST Gateway and Terrestrial Wideband projects supported nine video conferences and one conferencing demo. No SIMNET exercises or tests were held. Two of the video conferences held included four sites, four involved three sites, and four involved two sites. Conferences were held by multiple IETF working groups and DARPA sponsored groups. Participants included Mark Pullen (DARPA), Paul Mockapetris (ISI), Ira Richer (DARPA), Phill Gross (NRI), Danny Westine [Page 12]  Internet Monthly Report July 1990 Cohen (ISI), and many others. During July, gateways were added at NASA/Ames (FIX-west) and U. Maryland/SURANET (FIX-east) in order to interconnect the Terrestrial Wideband to other national backbone networks. Two gateways were also installed at University College London (UCL) and University of London Computer Center (ULCC). These together with the above-mentioned U. Md/SURANET gateway support a 512Kbps "fatpipe" connection between the US (DARPA, NSF, NASA) and the UK (RSRE, JNT, and UCL/ULCC). Work is in progress to also provide video conferencing over this link. Also during this month, the ST Gateway and Terrestrial Wideband projects supported five video conferences and one conferencing demo. No SIMNET exercises or tests were held. Two of the video conferences involved three sites and four involved two sites. Participants included multiple IETF working groups and DARPA sponsored groups, e.g., the IETF Router Requirements, Security, Open Routing, and Autonomous Networks working groups. Conferences were held that involved Mark Pullen (DARPA), Paul Mockapetris (ISI), and many others. Bob Hinden (Hinden@BBN.COM) CERFNET ------- Connections Coordination efforts continue with the Federal University de Rio de Janeiro to connect the network. The link will be connected to CERFnet via SDSC. Eventually, the university in Rio will serve as an access point to CERFnet and the Internet for many other Brazilian universities. CICESE, a research and education facility in Ensenada, Mexico is planning, within the next 6 months, to install a 56 kbps satellite link to CERFnet via SDSC, using a channel on the Mexican satellite, Morelles II. Installations Emulex Corporation, Irvine, CA, was installed on July 24, 1990 with a 56 kbps link to the University of California, Irvine. General Atomics, the research and development company which administers SDSC and CERFnet in San Diego, California will be connected to CERFnet via a microwave link on August 7, 1990. Westine [Page 13]  Internet Monthly Report July 1990 DIAL n' CERF, a dialup SLIP service, will expand to Caltech and the University of California campuses including Irvine, Los Angeles, and the UC Office of the President the week of July 30th. Semi-Annual Status Meeting CERFnet's semi-annual plenary meeting will the held at Caltech in Pasadena on August 21, 1990. by Tammy Hinton CICNET ------- The CICNet Request for Proposals for Network Operations and Management Support Services closed on July 6, 1990. There were a total of seven (7) responses submitted. Initial evaluations are expected to be completed by early August, with an announcement of award expected in early September. The CICNet Network Planning and Design Subcommittee has been actively involved in reconfiguring the CICNet T-1 backbone in the Chicago area to accommodate the addition of the NSFNet NSS at Argonne National Labs, as well as incremental growth in our bandwidth consumption. Design alterations are subject to approval by our Technical Board at the August meeting. CICNet traffic, as measured by the number of packets generated into the backbone by our nodes, appears to have leveled off. From February to June, 1990, the number of packets has been in a very narrow range around the 700 million level. This consistency, should it continue, will be useful in allowing us to identify exceptional occurences as the source of traffic bursts. by Joel Maloff CORNELL ------- No report received.

Hobby, "The Point-to-Point Protocol (PPP) Initial Configuration Options", UC Davis, July 1990. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT A new version of the Packet Video Host (PVP) was released this month. Improvements include a new more flexible and error-tolerant ST packet order-restoration algorithm, recognition and automatic adaptation to various codec types (including the one-frame-out- for-one-frame-in regimen of the Compression Labs codec) and two new keyboard commands - one to allow changes to the number of segments (ST packets) into which a video frame is divided, and the other to allow disordering, dropping and delaying of outgoing ST packets for debug purposes. The new PVP also continuously measures the video packet rates and sizes for use in the Flow Spec field of ST control messages. This is to assure identical codec settings at all sites and is meant to function with the next version of the ST protocol. PVP as well as the Voice Terminal (VT) program are being ported from the BBN Butterfly to the Sun Sparcstation. The most difficult problems were structure alignment and conversion of each program to be a single process. Porting of both programs has progressed to the point where ST control packets are exchanged to establish a connection. Testing and debugging of the voice data transmission code is the next step. Codec synchronization was added to MMCC, the multimedia conference control program. At conference initiation, the callee determines the codec type and video rate and synchronizes these choices across Westine [Page 16]  Internet Monthly Report July 1990 all sites. Once a conference is set up changes to these values are disallowed. RPC-based codec and crossbar servers were installed at all teleconferencing sites. Annette DeSchon, Dave Walden, Eve Schooler, Steve Casner (deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU, casner@ISI.EDU) FAST PARTS Paul Postel implemented a fully automated procedure for a second subset of FAST's rfq/quote handling. In addition to reaching vendors automatically via MCI Mail, FAST can now acquire a significant portion of its inplant terminal* quotes automatically. Request for quote information is automatically extracted from FAST's Oracle database into a mail message that is sent to "termserv", a mailbox on trader.isi.edu. Once the message arrives at "termserv", an ICON program parses it and creates a flat file which, in turn, is fed to another ICON program, "appscan". "Appscan" simulates the interactive behavior of a human operator using the inplant terminal and outputs price and availability for each line item. The resulting flat file is fed to still another ICON program that creates a mail message using the MCI Mail quote response template. This message is sent to FAST's mailbox for automatic parsing and insertion into FAST's database. Once in FAST's database, FAST's own processing ("extract") will "notice" the new quote and include it in a mail message to the customer initiating the quote request. *An inplant terminal allows direct lookup in a vendor's database. At this point, FAST has automated this lookup for two of its vendors, Hamilton Avnet and and Arrow Electronics.

New Projects: The NNSC is in the process of compiling a phone book for network managers. The phone book will list the domain and IP addresses for all technical contacts. We plan to publish and distribute the phone book sometime in late August. Changes to the Internet Resource Guide distribution list: Until now the NNSC has been distributing two email messages for each new entry to the Internet Resource Guide, one plain text and one in PostScript format. Because many people would prefer to receive only one or the other, we are in the process of spliting the present mailing list into two parts, one for those who want to receive text files, and one for those who want to receive PostScript files.

This plan calls for a restructuring of the governing structure of NWNet around a small seven member Executive Committee made up 2 originating members, 2 members of higher education, 2 members from industry and Westine [Page 19]  Internet Monthly Report July 1990 1 at large member. This Committee will advise an Executive Director and the Board of Directors on policy and direction. The membership dues and fees are expected to double for most members, reflecting the trend of NSFNet Regionals to be self sufficient by the mid 1990s. Two new networks were added to NWNet this month: Sequent Computer Systems, Inc., based out of Beaverton, Oregon connected at 56kbps to the Oregon Graduate Institute. Walker, Richer and Quinn, a software firm in Seattle, Washington connected to the University of Washington at 56kbps. The link between Boeing Computer Services and the University of Washington was upgraded from 56kbps to T1. by Dan Jordt NSF BACKBONE (Merit) ------------------- NSFNET Backbone Project The July, 1990 inbound packet count on the NSFNET Backbone increased 4.69% over June, for a total of 3,426,137,352 packets. As of 31 July 1990, 1744 networks were configured for announcement on the NSFNET Backbone. The relocation of NSS 14 at Seattle is rescheduled for August 14- 16. The move of NSS 9 at College Park was completed on July 9, and the move of NSS 8 at Princeton was completed July 23. Any questions may be directed to the regional network or to nsfnet- info@merit.edu. As a result of the relocation of NSS 9 at College Park, only the west coast interconnection between MILNET and the NSFNET was operational. DCA, in cooperation with all parties involved, is working to re-establish the connection to FIX-E in the very near future. The T1 link between the NSFNET at Ithaca and EASINET at CERN was production ready on July 12. Work is underway to implement BGP at this connection. A second interconnection between CA*Net and NSFNET is being coordinated between Montreal and Princeton. Elise Gerich of the Merit/NSFNET Internet Engineering staff, presented an NSFNET overview, as well as information on routing and procedures for establishing international connections to the Westine [Page 20]  Internet Monthly Report July 1990 NSFNET, to a meeting of the Pacific Communications Networking Project (PACCOM) in Hawaii, which included representatives from Japan, Australia, New Zealand, Korea and the United States. Jessica Yu of the Merit/NSFNET Internet Engineering staff, was an NSFNET representative to the FEPG meeting in Vancouver on July 30. Hans-Werner Braun, Principal Investigator for the NSFNET project, and Elise Gerich attended part of the meeting via conference call. An NSFNET overview was presented by Dale Johnson, manager of the Merit/NSFNET Network Operations Center, to those attending IETF on July 31. Jessica Yu shared information from early experiences in the use of BGP at the IWG discussion. The interim policy of the National Science Foundation regarding the acceptable use of the NSFNET is outlined in the file NETUSE.TXT, available for anonymous ftp from the directory NSFNET on NIS.NSF.NET. Merit/NSFNET Information Services, committed to providing current information on national networking to all users of the NSFNET backbone, will sponsor a two-and-a-half-day seminar in Ann Arbor, Michigan, November 12, 13, and 14, 1990. "Making Your NSFNET Connection Count" will be an informative seminar focusing on issues of interest to campus computing leaders, information systems and networking administrators, educational liaisons, librarians, and educators who want to learn more about national networking. Information may be obtained via e-mail to seminar@merit.edu or phoning 1-800-66-MERIT. Jo Ann Ward (jward@merit.edu) NTA-RE and NDRE --------------- No report received.

PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- No report received. RIPE (Reseaux IP Europeans) --------------------------- No report received. SAN DIEGO SUPERCOMPUTER CENTER ------------------------------ Our NTP Server has had a hard disk installed - this should greatly increase its MTBF. The MFEnet I link and software has been turned off at SDSC. ESnet is serving as a replacement. Our Proteon p4200 has been updated to the newest release. An additional link has been installed - 56k to S-CUBED - which will carry both TCP/IP and DECnet. We recently have been experiencing problems with complete DECnet routing loss over our Proteon links which is still being investigated. We have turned up a second dialup 56k user on our cisco using cisco's DECnet Address Translation Gateway. The hardware to support CSnet's Westcoast NSFnet gateway has arrived and been installed. It is scheduled to be turnedup in early Aug. Also during August, we are planning a peer change - from cisco/EGP to SUN/gated/EGP. Paul Love (loveep@sdsc.edu) Westine [Page 22]  Internet Monthly Report July 1990 SESQUINET --------- No report received. SRI ---- DDN NIC In July, we assigned 60 numbers to new government-sponsored IP networks and 90 numbers to new independent IP networks. The total number of all assigned IP numbers is now 5,222 which includes 3,012 sponsored networks and 2,210 independent networks. The total number of assigned Autonomous System numbers (ASNs) is now 700. There are currently a total of 1,831 registered domains which includes 49 at the top level, 1,732 at the second level, and 50 third-level MIL domains. Fred Ostapik attended IETF at UBC in Vancouver, Canada. He represented NIC in working groups concerning security and related issues. Douglas MacGowan (MACGOWAN@NIC.DDN.MIL) SURANET ------- No report received. TEXAS HIGHER EDUCATION NETWORK ------------------------------ No report received. UCL ---- The "Fat Pipe" installation at UCL (and ULCC) is progressing very well. New Butterflies and lines all installed and tested. Prof. Steve Wilbur attended the IETF in Vancouver. A paper on "Some Investigations into Policy Based Routing Schemes and Systems", by Eliasz and Crowcroft, was accepted for an IFIP conference in September. A followup paper by Eliasz has been submitted elsewhere. Eliasz has implemented a distributed prolog Westine [Page 23]  Internet Monthly Report July 1990 implementation of a policy term evaluator (based on a suggestion from David Hearn at RSRE). John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Our Internet connectivity was severely impacted by SURA outages ranging from minutes to days. A significant level of effort was expended in order to track problems and perform required software maintenance on machines outside SURA. Packet loss between UDel and hosts outside SURA due to link-level errors and router congestion has risen steadily over the last few months and is now at a level close to one percent. 2. Our DARTNET access line has been installed. We are expecting arrival of a donated SPARCstation router originally scheduled for shipment in June. 3. NTP fuzzball time servers at SDSC and UIUC have been ugraded with donated hard disks. Time servers at NCAR, Cornell and PSC have yet to upgrade. An NTP fuzzball time server originally operated at JvNC has been upgraded with a donated hard disk. It will be shipped to MIT when the NSS is installed there. 4. The new NTP Version 3 specification is available in PostScript form in the file pub/ntp/ntpv3.ps.Z on louie.udel.edu. A fuzzball implementation has been running for a couple of months. The specification document will be submitted as an RFC when one or both of the Unix daemon implementations have been upgraded and tested. 5. There are currently over 1000 clients of the nine fuzzball NTP primary (externally synchronized) time servers in the U.S. and Norway and probably a few hundred more clients of the six Unix primary servers. It is estimated that the time-synchronization subnet has at least doubled in size from about 2000 clents a year ago. There is a need to deploy NTP Version 3 implementations soon in order to reduce network overheads. There is also a need to develop a management and administration infrastructure, including SNMP provisioning and DNS registration.
