END-TO-END SERVICES ------------------- No internet related progres to report. Bob Braden (Braden@ISI.EDU) PRIVACY AND SECURITY -------------------- Progress continues on the implementation of privacy-enhanced mail. Representatives of BBN Communications, Trusted Information Systems, RSA Data Security and NIST met early this month at TIS to discuss a phased plan for release of mail software and beta testing. Early in January, representatives of BBN will be visiting RSADSI to solidify procedures to be used by RSADSI when it assumes full-scale Certifying Authority responsibility for the privacy e-mail community. On January 17-19, the PSRG will meet at Xerox PARC. This meeting will include a joint session with the End- to-End Research Group, and news of the discussion at the meeting will be submitted in the next monthly. Ken Rossen (kenr@BBN.COM) COLLABORATION TECHNOLOGY ------------------------ No report received. Westine [Page 3] Internet Monthly Report December 1989 INTERNET ENGINEERING REPORTS ---------------------------- IETF Report: Chair: Phill Gross/ NRI 1) I would like to welcome two new important members to the IETF Steering Group (IESG). Steve Crocker of Trusted Information Systems (TIS) will be the Director of the Security Area. His first monthly report is below. Steve is involved, among other issues, with developing a secure email system based on RFCs 1113-1115. Russ Hobby (UC-Davis) has joined us more recently as the Applications Area Director. Russ has already proposed some specific application projects, and will make his first report next month. This leaves only the Operations area unfilled. Until filled, I will continue to serve as the interim Director. My Operations Area report is below. 2) The next IETF meeting is at Florida State University at Tallahasse on February 6-9, 1990. The local host is Ken Hayes. The meeting is partly sponsored by the Department of Energy. The agenda for the February IETF is quite full (see below). There will be ~27 WGs meeting in ~37 sessions. There will be ~10 technical presentations, and a report from all area directors. 3) There will be an open meeting of the IESG at the February IETF. At the suggestion of Mike Karels at the last IETF meeting, we have scheduled the IESG from 4-7pm on Thursday so it does not conflict with other WG sessions or the technical presentations. The primary topic of the IESG will be the issue of intra-AD routing protocol (ie, IGP) standardization. 4) Agenda of the February 6-9 IETF Meeting at FSU: MONDAY, FEBRUARY 5 9:00-5:00 IS-IS Routing -- General Discussion (Ross Callon/ DEC) TUESDAY, February 6 8:15 AM IETF Registration and Coffee 8:55 AM Call to Order: Introductions, and Local Arrangements 9:00-12:00 AM Morning Working Group Sessions - Connection IP (Claudio Topolcic/ BBN) - IS-IS Routing -- IP Implementation Issues (Ross Callon/ DEC) - Interconnectivity (Guy Almes/ Rice) - Distributed File Systems (Craig Partridge/ BBN) Westine [Page 4] Internet Monthly Report December 1989 - Router Requirements (Philip Almquist/ Stanford, Jim Forster/ cisco) - User Documents (Karen Roubicek/ BBN, Tracy LaQuey/ U-Texas) - OSI Internet Management (formerly CMOT) (Lee LaBarre/ Mitre) 1:00-4:00 PM Afternoon Working Group Sessions - Connection IP (Claudio Topolcic/ BBN) - Interconnectivity (Guy Almes/ Rice) - User Services (Joyce Reynolds/ ISI) - Point to Point Protocol Extentions (Russ Hobby/ UC-Davis) - Alert Management (Louis Steinberg/ IBM) - JOMAAN (Gene Hastings/ CMU) - Multicast routing for OSPF (Steve Deering/ Stanford) 4:15-5:30 PM Technical Presentations - "OSPF Routing", (John Moy/ Proteon) (30 minutes) - "Open Routing Architecture", Marianne Lepp/ BBN (45 minutes) WEDNESDAY, FEBRUARY 7 8:55 AM Call to Order: Announcements 9:00- 9:15 Technical Presentation - "Internet Report", Zbigniew Opalka/ BBN) 9:15-12:00 AM Morning Working Group Sessions - Connection IP (Claudio Topolcic/ BBN) - OSI General (Ross Callon/ DEC, Rob Hagens/ U-Wisc) - Interconnectivity (Guy Almes/ Rice) - Router Requirements (Philip Almquist/ Stanford, Jim Forster/ cisco) - SNMP Authentication (Jeff Shiller/ MIT) - User Services (Joyce Reynolds/ ISI) - Point to Point Protocol Extentions (Russ Hobby/ UC-Davis) - Network Graphics (Craig Partridge/ BBN) - Open Routing (Marianne Lepp/ BBN) 1:00-4:00 PM Afternoon Working Group Sessions - Connection IP (Claudio Topolcic/ BBN) - Maximum Transmission Unit Discovery (Jeff Mogul/ DEC) and Router Discovery (Steve Deering/ Stanford) - Benchmarking Methodology (Scott Bradner/ Harvard) - TELNET (Dave Borman/ Cray) - IP over FDDI (Dave Katz/ Merit) - OSI X.400 (Rob Hagens/ U-Wisc) - Management Services Interface (Oscar Newkerk/ DEC) - Open Routing (Marianne Lepp/ BBN) 4:15-5:30 PM Technical Presentations - "Use of OSI IS-IS in IP and Dual Environments", Ross Callon 6:30 NOC Tools Working Group Session (Bob Enger/ Contel, Bob Stine/ Sparta) Westine [Page 5] Internet Monthly Report December 1989 THURSDAY, FEBRUARY 8 8:55 AM Call to Order: Announcements 9:00- 9:15 Technical Presentation - "ESnet Report", Tony Hain/ DOE (10 minutes) 9:15-12:00 AM Morning Working Group Sessions - Connection IP (Claudio Topolcic/ BBN) - Dynamic Host Configuration (Ralph Droms / Bucknell) - NOC Tools (Bob Enger/ Contel, Bob Stine/ Sparta) and User Services (Joyce Reynolds/ ISI) and User Documents (Karen Roubicek/ BBN, Tracy LaQuey/ U-Texas) - Transmission MIB (John Cook/ Chipcom) - TCP Big Windows (Craig Partridge/ BBN) - Router Requirements (Philip Almquist/ Stanford, Jim Forster/ cisco) - IP over Switched Megabyte Data Service (SMDS) (George Clapp/ Ameritech, Mike Fidler/ Ohio State) 1:00-4:00 Technical Presentations (45 minutes each) - "From Smart Drop to Congestion Control", Martha Steenstrup / BBN - "NORDUNET", Mats Brunnell / NORDUNET (45 minutes) - "Report of the Open Software Foundation", Brad Johnson / OSF (45 minutes) - "The Interop 89 Network", Philip Almquist/ Consultant (45 minutes) 4:30-7:00 PM Open Steering Group Meeting FRIDAY, FEBRUARY 9 8:55 AM Call to Order: Announcements 9:00-9:15 Technical Presentation - "NSFnet Report", TBD (15 minutes) 9:00-11:30 Working Group Area and Selected Working Group Presentations - Applications Area (Russ Hobby/ UC Davis) - Host and User Services Area (Craig Partridge /BBN) - Internet Services Area (Noel Chiappa /Consultant-Proteon) - Network Management Area (Dave Crocker /DEC) - Operations Area (Interim - Phill Gross/ NRI) - OSI Interoperability Area (Ross Callon /DEC and Rob Hagens /U-Wisc) - Routing Area (Bob Hinden /BBN) - Security Area (Steve Crocker /TIS) 11:30-12:00 AM Concluding Remarks (Phill Gross, NRI) Westine [Page 6] Internet Monthly Report December 1989 - IESG AREA REPORTS - OSI INTEGRATION AREA: Directors: Rob Hagens/UWisc, Ross Callon/ DEC Reported by Rob Hagens/ UWisc Several working groups of the OSI Area will meet at the February IETF. The OSI General WG will discuss the status of RFC 1006 ("ISO Transport Services on top of the TCP") as well as a proposed companion document (currently an Internet Draft) "OSI Connectionless Transport Services on top of the TCP". A newly formed working group, OSI NSAP Guidelines (OSI NSAP), will meet to discuss their task: a paper describing guidelines for the administration of NSAP addresses. The OSI X.400 WG will meet to discuss a scheme that will provide a default X.400 OR Address for users that currently have a domain- name-based 822 mail address. NETWORK MANAGEMENT AREA: Director: David Crocker/ DEC Very active month. SNMP, SMI, and MIB I are being considered for full Standard Status. MIB II for Draft or Proposed status. An OSI-oriented SNMP-based MIB is a candidate for Experimental status. NOCTools has a draft document, in time for IETF. AlertMan has a draft spec, in time for IETF. OIM has a draft MIB-II spec, in time for IETF. There also are rumors of CMOT product-oriented implementation interoperability testing in the offing. HOST AND USER SERVICES AREA: Director: Craig Partridge/ BBN User Services - Joyce Reynold was appointed Chairman of the User Services Working Group. Host-based Services- Nothing to report. Westine [Page 7] Internet Monthly Report December 1989 INTERNET SERVICES AREA: Director: Noel Chiappa/ Consultant, Proteon The main progress in this area this month was in the MTU Discovery and Router Detection WG's, which held a joint meeting, and made substantial progress towards picking final technical directions, allowing RFC drafting to begin. The consensus of the Router Discovery meeting was that a mechanism very similar to the ES-IS mechanism for hosts to discover routers, but based in ICMP, was what was desireable. Many other options, including use of a similar UDP based service, RIP, proxy ARP, a strict ES-IS subset, and a number of other new mechanisms, were discussed and eventually put to one side. The mechanism would allow both multi-cast and unicast requests, and routers would periodically multi-cast replies as well; the replies contain a "holding time" field. The latter features are intended to allow this mechanism to be used as part of a future "black hole detection" algorithm. The consensus of the MTU discovery meeting was that a cross between the "Report Fragmentation" (where the end host reports when it sees incoming fragments) and "Probe Path" (where the routers along the way indicate the max() of the MTU's of all the links) approaches. The mixed apprach was preferred because in a situation involving incremental deployment, you can guarantee neither that the end host has been upgraded (as required by the RF approach), nor that all the routers in the path have been (as required by the PP approach). The mechanism is an IP option which is included occasionally in packets. "This hybrid approach seems ... to combine the best of both methods: it gives accurate, early results (i.e., before a connection has to start sending big datagrams) without incurring fragmentation if the routers cooperate, it detects fragmentation if the receiver cooperates, and it causes conservative behavior otherwise." Several more new groups are in the process of being formed, and will be announced shortly. Chairpersons have been selected for the "IP over SMDS" and "IP Multi-media" WG's (the latter is looking at issues relating to connection of dissimilar networks below the router layer, such as by multi-media bridges), and the charters for those groups should be out shortly. In addition, it is hoped to form WG's to consider issuing a detailed specification for use of variable width subnet masks, and to prepare a complete enumeration of standards for transmission of different protocols on all common media; in places where formal Westine [Page 8] Internet Monthly Report December 1989 standards are not written down, it will create such standards, in cooperation with the appropriate standards bodies where possible. SECURITY AREA: Director: Steve Crocker/ TIS A formative period for this area. Jeff Schiller is running the sole working group and is focussed on IP authentication and SNMP authentication. Two documents on SNMP authentication are being reviewed internally and should emerge for wider review shortly. More information on IP authentication later. Rich Pethia, the leader of the CERT (Computer Emergency Response Team) at the SEI (Software Engineering Institute) has agreed to form a new working group in this area. There exact charter is under discussion. Issues of interest range from defining a security policy for the Internet to specific protocol developments for trusted distribution and/or audit of software. These topics and others will be discussed in the forthcoming draft five year plan and shared with the IESG for inputs. OPERATIONS AREA: Interim Director: Phill Gross/ NRI We are beginning to look at ways that the JOMAAN WG can better serve the needs of both IETF and the Regional networks. We are in the process of talking to FARNET on this and other ways of better cooperation. Craig Partridge is starting a new WG to help end users report and track down network problems. This has both a User Services and an Operations flavor, and demonstrates a new IESG emphasis on the issues of operational stability. There has long been regular status reporting of the major agency backbones at the IETF plenary technical sessions. We are now trying to better organize and coordinate these and other operational reports. We are planning an ad hoc meeting at the Feb IETF to look at common formats and common information for each agency report. One of the goals will be to identify the key information to represent network performance and status, and agree on similar presentations of this information. The fullness of the Feb IETF agenda has forced this to be an evening meeting. Phill Gross (pgross@NRI.RESTON.VA.US) Westine [Page 9] Internet Monthly Report December 1989 INTERNET PROJECTS ----------------- BARRNET ------- No report received. BOLT BERANEK AND NEWMAN INC. ---------------------------- TERRESTRIAL WIDEBAND NETWORK During December, the Terrestrial Wideband supported 6 video teleconferences. This included two RIG discussions led by Ira Richer and Bob Braden. The second meeting was the first official four-site conference including BBN, DARPA, SRI and ISI. The Internet Engineering Steering Group also met this month. ST/IP GATEWAY Work continued on the ST gateway software and Terrestrial Wideband infrastructure needed to support large scale distributed wargaming (SIMNET). The initial version of the SIMNET ST host was completed this month. This host successfully collected traffic from 600 simulated vehicles at one SIMNET site and delivered it to another site. These sites were connected by two ST gateways and three Terrestrial Wideband Packet Switches in a lab environment. These were set up to simulate the delay which would exist in a real network. Packet integrity and low delay were verified by wargame simulators at the second site which integrated this traffic with other local wargame exercise traffic. EURO-DRI INFRASTRUCTURE Upgrades were installed in the Butterfly Gateways at UCL, RSRE (U.K.), and CNUCE (Italy) which included processors, new interfaces, fast load board, and new software and configurations. With the fast load boards, each machine now can be rebooted in less than 3 minutes. New terminals were also installed, and people at the sites discussed operations and theory of gateway use. Gateway operations at SHAPE Technical Centre are being worked out, so that the site can support the level of service that is needed, both for themselves, and for other sites which may eventually connect through them. Westine [Page 10] Internet Monthly Report December 1989 TCP/ISO TRANSLATION Outlines for work with protocol translation between TP4 and TCP with J.Wilkes at SHAPE Technical Centre have been discussed. Plans are to compare different types of translation at the transport layer, first the transport bridging services available in ISODE, and then completing an implemention which translates individual PDU's at the transport level, between the underlying network service interfaces. INTERNET RESEARCH We distributed copies of the draft document "Inter-Domain Policy Routing" to members of the Open Routing Working Group and are presently awaiting comments. Once the revisions suggested by the comments have been incorporated, we will release the document as an Internet Draft. This we expect to occur by the end of January. A meeting is scheduled at the February IETF to allow this document to be openly presented and discussed. In the draft, we present an architecture for policy routing among administrative domains within the Internet. The objective of inter-domain policy routing is to synthesize and maintain routes between source and destination administrative domains (ADs), providing user traffic with the requested service within the constraints stipulated by the administrative domains transited. Each administrative domain autonomously defines policy requirements for traffic generated within it and sets and enforces policy restrictions on traffic passing through it. We emphasize that policy includes service access, quality, and charge. The proposed routing architecture comprises the following functions: collection, distribution, and maintenance of topology- and policy-related information for routing; synthesis and selection of routes requested by the source ADs; installation, verification, maintenance, and repair of routes across the Internet; and packet forwarding from one AD to the next. The architecture is designed to accommodate an Internet with tens of thousands of administrative domains collectively containing hundreds of thousands of local networks. The draft also contains suggestions for protocols to support the functionality of inter-domain policy routing. We are presently pursuing the detailed specification of these protocols. Bob Hinden (Hinden@BBN.COM) Westine [Page 11] Internet Monthly Report December 1989 CERFNET ------- No report received. CICNET ------- CICNet has been active in a variety of areas during the past month. These include the addition of three new Computer/Telecommunications members, two new Universities, the further progress of our Video Applications Study Group, and the funding of a PC/Fax hybrid project for library applications. In addition, our network traffic, in terms of packets transported, increased 112% from May to November. Effective at the December meeting of the CICNet Board of Directors, Ameritech, Consolidated Network Inc., and MCI have become corporate members of CICNet. This entitles them to participate in the various applications oriented affinity groups established by CICNet as members rather than as vendors. They are also entitled to network connectivity consistent with acceptable use policies. In addition, Purdue University and Indiana State University were approved as Category II, Other University/Nonprofit Members of CICNet. CICNet's Video Study Group met on November 9, 1989 in Ann Arbor to evaluate the various types of video applications and solutions that might be appropriate over our network. Participants include end users, networking groups, and vendors. Presentations were made by members of the group and covered actual applications, video technologies, and video networking issues. The study Group split into two task forces: applications and technology. By the end of January, the Applications group will arrive at two to three solidly defined uses for video-based services. Concurrently, the technology task force will be gathering information on all available solutions, and be prepared to match those with the selected applications. Once accomplished, CICNet plans to proceed with tests. At our October Library Director's meeting, a group from The Ohio State University, led by Bob Dixon, successfully demonstrated the use of a Group III Fax, PC with Fax card, and custom-designed software to transmit and receive facsimile messages over the Internet. CICNet is assisting in the deployment of the project, both as a testbed and through modest levels of funding. Westine [Page 12] Internet Monthly Report December 1989 During November, 1989, CICNet carried 550 million packets, and averaged over 18 million packets per day. CICNet also measures the degree to which individual backbone network segments become saturated during discrete 15 minute "busy periods". During May, the greatest degree of concentration measured was 7%. During November, it exceeded 30% on several network segments. A measurement of 40% or greater indicates potential network congestion. CICNet has created a standing Network Planning Subcommittee to monitor and address these potential concerns. by Joel Maloff CORNELL ------- No report received. ISI --- INTERNET CONCEPTS PROJECT Bob Braden began plans for the DRI open gateway testbed. He organized two teleconferences to gather information about candidate hardware/software platforms for the open gateways. This issue is close to resolution. Bob Braden also worked on a new version of statspy that incorporates a major revision to the internal compilation algorithms, to improve performance and to support the entire extended language described in the SIGCOMM 88 paper. The new version is expected to be released as version 2.5 early in 1990. An ISI technical report on statspy internal design was also completed; this is an expansion and revision of the SIGCOMM paper. It includes a much more complete discussion of compilation algorithms and a brief overview of the program internals. Finally, Braden did preparatory work for the IAB meeting to be held the first week of January 1990. Jon Postel and Danny Cohen hosted the System Engineering for Testbed SEFT meeting at ISI, Dec. 1, 1989. Discussions of this meeting pertained to the engineering of DRI testbed networks. Jon Postel hosted the CORNETT meeting at ISI Dec 13, 1989, to discuss this testbed network. Greg Finn gave a lecture at USC campus on Dec 13 on "IP Source Quench Congestion Control Algorithm." Westine [Page 13] Internet Monthly Report December 1989 Four RFCs were published this month. RFC 1135: Reynolds, J., "The Helminthiasis of the Internet", USC/ISI, December 1989. RFC 1136: Hares, S., and D. Katz, "Administrative Domains and Routing Domains A Model for Routing in the Internet" Merit/NSFNET, December 1989. RFC 1137: Kille, S., "Mapping Between Full RFC 822 and RFC 822 with Restricted Encoding", University College London, December 1989. RFC 1138: Kille, S., "Mapping Between X.400 (1988) / ISO 10021 and RFC 822". Ann Westine (Westine.ISI.EDU) MULTIMEDIA CONFERENCING PROJECT The first official four-site teleconference was held this month after earthquake repairs at the SRI site were completed. The control protocol used by MMCC, the multimedia conference control program, was enhanced this month to combat pathological behavior caused by network partitioning. Additional timeouts were put in place to avoid getting stuck waiting for another site to respond. Mechanisms now exist for detecting state inconsistencies and restoring state information when sites reconnect after a partition. We continued our investigation of the sound I/O facilities on the NeXT machine. Although we have made some progress in understanding the low level sound-driver interface, we have not yet been successful in playing back sound recorded from the microphone, in real time. Steve Casner, Annette DeSchon, Dave Walden, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU) FAST PARTS Alan Katz continued work on the mail-based FAX server. We can now send FAXes manually from any workstation at ISI. The mail interface to FAX is almost done. The FAST project has started to use the server for price quotes and ordering on a restricted test basis. Westine [Page 14] Internet Monthly Report December 1989 The system uses a Complete FAX 4800 baud FAX card in an IBM PC which talks to a Sun workstation via RS232. The FAX card plus PC acts as a FAX modem to the Sun. The software is written in GNU Emacs LISP. Alan Katz (katz@ISI.EDU) JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK --------------------------------------------- No report received. LOS NETTOS ---------- We made available via anonymous FTP, copies of the Los Nettos route monitoring scripts using SNMP to those who requested it. No new members have been added this month. Walt Prue (Prue@ISI.EDU) MERIT/UMNET ----------- No report received. MIDNET ------ No report received. MIT-LCS ------- The network simulator was ported to run on the Cray-2 at the MIT Super Computer Facility. Significant progress was made on the preparation of two drafts for discussion in the IETF Authentication Working Group. Chuck Davin (jrd@PITT.LCS.MIT.EDU) Westine [Page 15] Internet Monthly Report December 1989 MITRE Corporation ----------------- No report received. MRNET ----- The incumbents of the MRNet Executive Committee were re-elected: Chair Mahlon Stacy Vice Chair Jeff Wabik Treasurer Carl Henry Secretary Tim Salo The T1 line between MRNet and the NSFnet backbone at UIUC is now operational. Jeff Wabik coordinated the transition to the new line with UIUC and MRNet members. The old 56k bps line to UIUC has been cancelled. This line was funded by the Army High Performance Computing Research Center (AHPCRC) contract. I expect substantial increased usage as the AHPCRC gets under way. The Army Supercomputer Network (ASnet), the network which connects the AHPCRC to Army sites, should be connected to MRNet during the next month. by Tim Salo (tjs@msc.umn.edu) NCAR/USAN --------- No report received. NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- During December the Open Software Foundation, IBM Cambridge Scientific Center, the Nelson Companies, Brandeis University, GTE Laboratories, Williams College and Xyplex Corporation were connected to the network. NEARnet's core was reconfigured to improve redundancy. Operation of the network continued to be stable. by John Rugo (jrugo@bbn.com) Westine [Page 16] Internet Monthly Report December 1989 NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Craig Partridge attended the IESG Security Meeting in Washington, D.C. The NNSC published additions to Chapters 1, 5, and M of the Internet Resource Guide. Requests to be added to or removed from the distribution list should go to resource-guide- request@nnsc.nsf.net. The guide is also available via anonymous ftp at , cd resource-guide. by Corinne Carroll NORTHWESTNET ------------ As of January 2, 1990 NorthWestNet technical management has moved from Boeing Computer Services (BCS) to the NorthWestNet member institutions. The University of Washington has taken over the responsibility for all NorthWestNet network operation center functions. These functions include physical communications circuit monitoring, problem identification, verification of problem resolution, performance monitoring and reporting, and domain name services. NorthWestNet trouble reports should be made to the University of Washington at (206)543-5128. by Dale Smith (dsmith@oregon.uoregon.edu) NSF BACKBONE (Merit) ------------------- Due to the December holiday period traffic on the backbone dropped slightly from November. The total packet count for December was 2,087,081,146 which is 11.6 million less then November 1989. Daily traffic was lower beginning on December 23 through the end of the year. Total network announcements through December 31 stand at 927 compared to 897 at the end of November. SYNCHRONIZING THE CLOCKS As we moved into the new decade a "leap second" was added to official clocks around the world. The NSFNET adjustment was automatically handled by a new implementation of the Network Time Protocol, configured and installed on the RTs at all nodes on the backbone by Dave Katz. The new implementation was written by Dennis Ferguson of the University of Toronto. Westine [Page 17] Internet Monthly Report December 1989 MERIT/NSFNET STAFF ACTIVITIES DURING DECEMBER Elise Gerich was an invited speaker at a ComForum event sponsored by the National Engineering Consortium: "Broadband: Services, Technology and the Future." Elise spoke about the architecture of NSFNET and the future of the network as a national data superhighway. Dave Katz hosted a working group to develop an Internet standard for the use of the OSI IS-IS (IS = Intermediate System) routing protocol in IP-only and dual (OSI and IP) environments. RFC 1136, "Administrative Domains and Routing Domains - A Model for Routing in the Internet" by Susan Hares and Dave Katz has been published. This document proposes a model for describing routing within the Internet, based on the OSI Routing [sic] Framework (ISO TR 9575). by Patricia G.

PREPNET-Pennsylvania Research and Economic Partnership Network -------------------------------------------------------------- The network simulator was ported to run on the Cray-2 at the MIT Super Computer Facility. Significant progress was made on the preparation of two drafts for discussion in the IETF Authentication Working Group. Thomas W. Cummings Westine [Page 18] Internet Monthly Report December 1989 PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- No report received. SAN DIEGO SUPERCOMPUTER CENTER ------------------------------ During December, we moved all systems (hosts, routers, printers, etc.,) to our Class B Address (132.249). Our Class C Address (192.12.207) will be retained for experimental use. With this change we have finally subnetted our building using the NSC EN641's multiple Ethernet ports as the hub. A cisco AGS is serving as backup. The move was accomplished during two days (18 & 28 December) with the normal cleanup following each session. During the second session, we uncovered several "glitches" with name servers, old host tables, etc. We have established SNMP sessions to our major hosts which support the protocol, all routers, etc. As such items as our Fastpaths are upgraded, they too will be monitored by SNMP. by Paul Love (loveep@sds.sdsc.edu) Since our last report: Both our Proteon p4200 and cisco AGS have been updated to the latest rev levels. We continue to have linemode problems with Telnet under UNICOS - usually caused by non-cooperating clients. Our old PSN (26) finally did get removed. The latest version of Multinet has been installed. With it, our VMS systems can be watched by SNMP. by Susie Arnold (susie@sds.sdsc.edu) SESQUINET --------- No report received. Westine [Page 19] Internet Monthly Report December 1989 SRI ---- In December, 26 new connected IP network numbers are assigned. In addition, 61 unconnected IP numbers are assigned this month. The total number of all assigned IP numbers is now 3,740 which includes 2,125 connected networks and 1,615 unconnected networks. The total number of Assigned Autonomous System numbers (ASNs) is 560. There are currently a total of 1,277 registered domains which includes 45 at the top level, 1,191 at the second level, and 41 third-level MIL domains. Douglas MacGowan SURANET ------- No report received. TEXAS HIGHER EDUCATION NETWORK ------------------------------ No report received. UCL ---- No activity to report for December. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Paul Schragger continued work on "trailblazer" reservation algorithms for gigabit networks. Mike Davis continued work on NSFNET traffic-monitoring data. Erik Perkins continued review and preparation for RIG-related experiments. Ken Monington continued work toward a Master's thesis on clock- synchronization algorithms. Dave Mills attended a DARPA telemeeting on RIG-related experiments. 2. Edited proceedings of the INARC Workshop on the Future of the Internet System Architecture and TCP/IP Protocols, held at U Delaware last June, are to appear in the next issue of the ACM Computer Communication Review. Westine [Page 20] Internet Monthly Report December 1989 3. Improved algorithms for use in the Network Time Protocol have been implemented and are now operating in all fuzzball primary and secondary time servers. The new design improves timekeeping accuracy and frequency stability by about a factor of ten, while reducing network overhead by a factor of 16. The overall performance of the NTP system is reported in a paper to appear in the next issue of the ACM Computer Communication Review. 4. The kind folk at the US Naval Observatory calibrated our exotic cesium clock to within the microsecond. Modifications to the fuzzball now provide precise seconds synchronization to the cesium clock with seconds ambiguity resolved by radio or NTP. All time servers, radios and oscillators within reach of campus nets are now verifiably synchronized to within a millisecond of UTC. We are monitoring the system using a LORAN-C receiver calibrated with the aid of precision geographic coordinates. The scheme demonstrates the practicality of unambiguous, precision synchronization in areas of the world where radio services are unavailable. 5. The Great Leap of '89, being a saga of the transient response of the Internet time servers to the insertion of a leap second in the international time scale, was something less than a complete success. Carefully prepared plans to avoid disruption due to confused radio clocks and misleaped servers didn't work in all cases and led to bizarre behavior something like a pinball machine. We all learned much from this, but won't get a chance to test it for another 18 months or so. Dave Mills (Mills@UDEL.EDU) UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET -------------------------------------------------- No report received. WESTNET -------- 1. We have begun to address the issue of cost allocation for when NSF funding is withdrawn. Any suggestions from other regionals would be most welcome. 2. US West/Advanced Technologies was recently connected in Colorado. Westine [Page 21] Internet Monthly Report December 1989 3. Grand Canyon Univ and Northern Arizona Univ were connected in Arizona. 4. Wyoming has begun the task of connecting state colleges into the Internet. by David C. M. Wood (dcmwood@spot.colorado.edu) Pat Burns (pburns@csupwb.colostate.edu) INTERNET CONCEPTS PROJECT Bob Braden began plans for the DRI open gateway testbed. He organized two teleconferences to gather information about candidate hardware/software platforms for the open gateways. This issue is close to resolution. Bob Braden also worked on a new version of statspy that incorporates a major revision to the internal compilation algorithms, to improve performance and to support the entire extended language described in the SIGCOMM 88 paper. The new version is expected to be released as version 2.5 early in 1990. An ISI technical report on statspy internal design was also completed; this is an expansion and revision of the SIGCOMM paper. It includes a much more complete discussion of compilation algorithms and a brief overview of the program internals. Finally, Braden did preparatory work for the IAB meeting to be held the first week of January 1990. Jon Postel and Danny Cohen hosted the System Engineering for Testbed SEFT meeting at ISI, Dec. 1, 1989. Discussions of this meeting pertained to the engineering of DRI testbed networks. Jon Postel hosted the CORNETT meeting at ISI Dec 13, 1989, to discuss this testbed network. Greg Finn gave a lecture at USC campus on Dec 13 on "IP Source Quench Congestion Control Algorithm." Westine [Page 13] Internet Monthly Report December 1989 Four RFCs were published this month. RFC 1135: Reynolds, J., "The Helminthiasis of the Internet", USC/ISI, December 1989. RFC 1136: Hares, S., and D. Katz, "Administrative Domains and Routing Domains A Model for Routing in the Internet" Merit/NSFNET, December 1989. RFC 1137: Kille, S., "Mapping Between Full RFC 822 and RFC 822 with Restricted Encoding", University College London, December 1989. RFC 1138: Kille, S., "Mapping Between X.400 (1988) / ISO 10021 and RFC 822". Ann Westine (Westine.ISI.EDU) MULTIMEDIA CONFERENCING PROJECT The first official four-site teleconference was held this month after earthquake repairs at the SRI site were completed. The control protocol used by MMCC, the multimedia conference control program, was enhanced this month to combat pathological behavior caused by network partitioning. Additional timeouts were put in place to avoid getting stuck waiting for another site to respond. Mechanisms now exist for detecting state inconsistencies and restoring state information when sites reconnect after a partition. We continued our investigation of the sound I/O facilities on the NeXT machine. Although we have made some progress in understanding the low level sound-driver interface, we have not yet been successful in playing back sound recorded from the microphone, in real time. Steve Casner, Annette DeSchon, Dave Walden, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU) FAST PARTS Alan Katz continued work on the mail-based FAX server. We can now send FAXes manually from any workstation at ISI. The mail interface to FAX is almost done. The FAST project has started to use the server for price quotes and ordering on a restricted test basis. Westine [Page 14] Internet Monthly Report December 1989 The system uses a Complete FAX 4800 baud FAX card in an IBM PC which talks to a Sun workstation via RS232. The FAX card plus PC acts as a FAX modem to the Sun. The software is written in GNU Emacs LISP.

MRNET ----- The incumbents of the MRNet Executive Committee were re-elected: Chair Mahlon Stacy Vice Chair Jeff Wabik Treasurer Carl Henry Secretary Tim Salo The T1 line between MRNet and the NSFnet backbone at UIUC is now operational. Jeff Wabik coordinated the transition to the new line with UIUC and MRNet members. The old 56k bps line to UIUC has been cancelled. This line was funded by the Army High Performance Computing Research Center (AHPCRC) contract. I expect substantial increased usage as the AHPCRC gets under way. The Army Supercomputer Network (ASnet), the network which connects the AHPCRC to Army sites, should be connected to MRNet during the next month. by Tim Salo (tjs@msc.umn.edu) NCAR/USAN --------- No report received. NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- During December the Open Software Foundation, IBM Cambridge Scientific Center, the Nelson Companies, Brandeis University, GTE Laboratories, Williams College and Xyplex Corporation were connected to the network.

The University of Washington has taken over the responsibility for all NorthWestNet network operation center functions. These functions include physical communications circuit monitoring, problem identification, verification of problem resolution, performance monitoring and reporting, and domain name services. NorthWestNet trouble reports should be made to the University of Washington at (206)543-5128. by Dale Smith (dsmith@oregon.uoregon.edu) NSF BACKBONE (Merit) ------------------- Due to the December holiday period traffic on the backbone dropped slightly from November. The total packet count for December was 2,087,081,146 which is 11.6 million less then November 1989. Daily traffic was lower beginning on December 23 through the end of the year. Total network announcements through December 31 stand at 927 compared to 897 at the end of November. SYNCHRONIZING THE CLOCKS As we moved into the new decade a "leap second" was added to official clocks around the world. The NSFNET adjustment was automatically handled by a new implementation of the Network Time Protocol, configured and installed on the RTs at all nodes on the backbone by Dave Katz. The new implementation was written by Dennis Ferguson of the University of Toronto. Westine [Page 17] Internet Monthly Report December 1989 MERIT/NSFNET STAFF ACTIVITIES DURING DECEMBER Elise Gerich was an invited speaker at a ComForum event sponsored by the National Engineering Consortium: "Broadband: Services, Technology and the Future." Elise spoke about the architecture of NSFNET and the future of the network as a national data superhighway. Dave Katz hosted a working group to develop an Internet standard for the use of the OSI IS-IS (IS = Intermediate System) routing protocol in IP-only and dual (OSI and IP) environments. RFC 1136, "Administrative Domains and Routing Domains - A Model for Routing in the Internet" by Susan Hares and Dave Katz has been published.
