Among the matters discussed at this meeting were the following: A. Network Management Policy and Direction Action was initiated to draft a replacement for the network management policy RFC [RFC-1052, "IAB Recommendations for the Development of Internet Network Management Standards", V. Cerf, April 1988]. This will probably involve a meeting or workshop to consider the future course of network management in the Internet. B. Acceptable Use The IAB will attempt to draft guidelines on acceptable use policies for mailing lists, and will try to cause the publication of acceptable use policies for existing transit networks. C. International Members The IAB made a commitment to add at least one non-US member, to be chosen at the January 1991 meeting. This reflects the increasing internationalization of the Internet. D. ANSI Affiliation The IAB discussed possible mechanisms for affiliation with ANSI for the purposes of setting Internet standards. No conclusion was reached, but investigation is continuing. E. RSADSI Agreement The IAB reviewed the latest draft of an agreement that an organization will have to sign with RSA Data Security, Inc. in order to become a certifying authority for Privacy Enhanced Mail (PEM) certificates. This agreement draft will shortly be published for information. F. IP Address Space Growth Noel Chiappa, IESG area director for Internet Services, summarized the alternatives for handling future growth in the number of Internet network numbers. Although the duration of the present exponential growth is by no means certain, it was Westine [Page 3]  Internet Monthly Report October 1990 agreed that the responsible approach is to plan for the worst case. The emphasis of this discussion was on exhaustion of the IP address space, although it was recognized that routing catastrophes are likely to come much sooner. G. OSI NSAP Address Assignment Dave Katz provided valuable input to a discussion on the assignment of NSAP addresses for OSI nodes in the multiprotocol Internet. When complete, minutes of this meeting will be announced and made available for anonymous FTP. The IAB will meet jointly with the IESG in January 1991. In addition, all those IAB members who are able will attend the Boulder IETF meeting. INTERNET STANDARDS ACTIONS The IAB has approved the following IESG recommendation: o Proposed Standard state for the MTU Discovery procedure developed by the "IP MTU Discovery" Working Group of the IETF, chaired by Jeff Mogul. This proposal elicited considerable discussion, since it will make a significant change in the fragmentation strategy of the Internet: the Don't Fragment bit in the IP header will normally be turned on. The Working Group had examined a number of alternative possibilities and made a convincing case that their approach best meets the scalability requirement while handling backwards compatibility in a reasonable manner. The IESG recommended the approval of: o Proposed Standard state for the Telnet Environment Option, developed by the IETF "Telnet" Working Group, and described in the Internet Draft . However, the IAB has not yet approved this, because of concern that this option could be an open door for non-interoperable, undocumented, vendor-specific Telnet options. Resolution of this issue with the IESG and the Telnet WG is underway. Westine [Page 4]  Internet Monthly Report October 1990 PREVIOUS MEETING MINUTES The minutes of the previous three IAB meetings are available for anonymous FTP from host VENERA.ISI.EDU with the pathnames: pub/IABmins.jan90.txt pub/IABmins.apr90.txt pub/IABmins.jun90.txt Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- The ANRG has a one day video conference tentatively planned for November 20. Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No internet-related progress to report. Bob Braden (Braden@ISI.EDU) PRIVACY AND SECURITY -------------------- Steve Kent chaired a panel on Internet Privacy-Enhanced Mail at Interop '90 early this month, and software and prototype hardware being developed by BBN in support of the P-E Mail registration process were shown at BBN's booth during the exhibition. Panel speakers included David Balenson, Steve Kent, and Ken Rossen of the PSRG and Burt Kaliski from RSA Data Security, Inc. The Privacy and Security RG met for three days from October 23- 25 at MITRE's McLean, Virginia facility, thanks to the hospitality of Rob Shirey. Major topics of discussion during this meeting were implementation status of and protocol changes to P-E Mail. The ongoing beta test of TIS's reference implementation, certificate interoperability testing with MIT and DEC implementations, and discussions during the last several PSRG meetings have all helped solidify a list of changes to the Westine [Page 5]  Internet Monthly Report October 1990 RFCs. This list will be distributed presently on the "pem-dev" mailing list. Editing of the RFCs is underway now with an expectation that revisions will be submitted within the next couple of months. RFC 1113 is being edited by John Linn, 1114 by Steve Kent and Ken Rossen, and 1115 by David Balenson. Subsequent to the RFC reissue, major work items will be the upgrade of TIS's reference implementation for compatibility with the changed RFCs, integration of BBN's ON software and hardware with the mail processing implementation, and preparation by RSADSI for assumption of its role as top-level certification authority and public notary. In anticipation of the latter item, representatives from BBN and RSADSI met early this month to exchange documentation for ON/CA hardware and software and to discuss further plans for support of RSADSI's role. At the McLean PSRG meeting, more detailed scheduling work was initiated, and RSADSI, BBN, and TIS expect to consult further on scheduling matters during November. Rob Shirey supplied a draft Internet Security Architecture RFC for discussion at the McLean meeting. The comprehensive architecture provides a framework for diverse protocol security enhancement efforts in the Internet community. The RG went over this document in some detail during the meeting. Group members in cooperation with Steve Crocker, IETF AD for Security, will be considering which other Internet RGs and WGs are best suited to specific contributions to the architecture. The draft Internet Security Policy guidelines document supplied by the Security Policy Working Group was also discussed at the McLean meeting. Reaction to this document was also generally favorable, and Steve Crocker will be conveying specific comments to the draft authors. Other topics discussed at McLean include plans for the MD4 algorithm in the Internet, and further interactions between the PSRG and the IETF. The latter included a discussion of the newly formed Security Area Advisory Group (SAAG). More detail on these topics appears in Steve Crocker's report. The next meeting of the PSRG will be held from 12-14 February at Xerox in Pasadena, CA. Ken Rossen (kenr@BBN.COM) Westine [Page 6]  Internet Monthly Report October 1990 COLLABORATION TECHNOLOGY ------------------------ No report received. INTERNET ENGINEERING REPORTS ---------------------------- 1) Reminder -- The next IETF meeting will be December 3-7, 1990 in Boulder Colorado. The meeting is being jointly sponsored by by Westnet and NCAR. Carol Ward (University of Colorado) and Don Morris (NCAR) are the local hosts. Logistics information and a preliminary agenda have been sent to the IETF mailing list. For a copy of this information, or to be added to the IETF mailing, please send to IETF-REQUEST@ISI.EDU. 2) We have made another minor change in how the IETF areas are aligned. We have decided to divide the activities of the Host and User Services Area (Craig Partridge/BBN). The Host and User Services area has included 3 types of activities: application services (eg, nfs, rpc, graphics, etc), transport services (eg, TCP, UDP), and user services. The first will be moved into the Applications area (Russ Hobby/UCDavis), the second will be moved into the Internet area (Noel Chiappa/Consultant), and user services will be made into a separate area by itself. I am very pleased to announce that Joyce Reynolds/ISI will be able to join the IESG as area director for the new User Services area. Joyce was formerly the chair of the User Services WG. Craig will remain on the IESG in an at-large position. 3) Report on documenting the IESG standards process (from David Crocker/DEC): A preliminary draft of the IETF standards process was submitted to the IESG, as a basis for further discussion. The handling of materials which come from sources other than IAB working groups is proving particularly challenging. Further, there appears to be a need to balance near-term and/or community-desired solutions which might not represent as strong a technical solution as the IAB and IESG would want. Westine [Page 7]  Internet Monthly Report October 1990 4) Report on the Routing Area (from Bob Hinden/BBN) This is the month to announce name changes for two working groups. The Interconnectivity working group (IWG) is now the Border Gateway Protocol working group (BGP). The Open Routing working group (OR) is now the Inter-Domain Policy Routing working group (IDPR). The new names better reflect the work that each group is doing. A charter was written by George Clapp for the new routing area working group dealing with IP routing over large public data networks. The group will meet for the first time at the upcoming IETF meeting in Boulder, CO, Dec. 3-7. The charter is as follows: IP over Large Public Data Networks (iplpdn) Chair(s): George Clapp, meritec!clapp@bellcore.bellcore.com Mailing Lists: General Discussion: iplpdn@nri.reston.va.us To Subscribe: iplpdn-request@nri.reston.va.us Description of Working Group: The IP over Large Public Data Networks Working Group (IPLPDN WG) will specify the operation of the TCP/IP protocol suite over public data networks (PDNs) such as SMDS, ISDN, X.25 PDNs, and Frame Relay (FR). The working group will develop and define algorithms for the resolution of IP addresses and for the routing of IP datagrams over large, potentially global, public data networks. The IP over SMDS Working Group has defined the operation of the Internet protocols when SMDS is used to support relatively small virtual private networks, or Logical IP Subnets (LISs). Issues arising from public and global connectivity were delegated to the IPLPDN WG. The IPLPDN WG will also continue the work of the Private Data Network Routing Working Group (pdnrout) on X.25 PDNs. This work will be extended to include call management and the use of the ISDN B channels for the transport of IP datagrams. Address resolution and routing over Frame Relay will also be discussed. Westine [Page 8]  Internet Monthly Report October 1990 5) Report from the Network Management Area and Directorate (from Chuck Davin/MIT): This month the membership of the SNMP Network Management Directorate is in place, and the board will organize itself at the December IETF meeting. Ted Brunner (Bellcore) Jeff Case (University of Tennessee) Chuck Davin (MIT) Frank Kastenholz (Racal Interlan) Keith McCloghrie (Hughes LAN Systems) Dave Perkins (3Com) Marshall Rose (Performance Systems International) Steve Waldbusser (Carnegie Mellon University) Steve Willis (Wellfleet Communications) The board will serve as a focus for broad community input into the development of SNMP network management within the IETF. Its responsibilities will center on guiding and reviewing the MIB development activity, on assuring that individual MIB activities are consistent and complementary one with another, and on overseeing continued growth and evolution in the management architecture. Phill Gross (pgross@NRI.RESTON.VA.US) Westine [Page 9]  Internet Monthly Report October 1990 INTERNET PROJECTS ----------------- BARRNET ------- Nearly 150 persons from over 75 organizations attended BARRNet's first annual workshop for current and prospective members on October 29th. The workshop was held at Stanford University, where BARRNet's Network Operations Center is located. Attendees learned about BARRNet's organizational and technical evolution, resources that are available on the Internet, simple troubleshooting techniques, and more. Six new members were approved in October, bringing the total number of BARRNet members to 75; of these 75, 60 are currently connected. Two new connections were made in October, including the first 9600 bps dedicated line as part of the low-speed services expansion (see below). BARRNet staff has been assisting local universities and community colleges to prepare applications for NSF grants for Internet connections. Five Bay Area institutions and college districts have completed and submitted proposals to date. BARRNet's low-speed host connection service trial is underway with 9600 bps dial-in connections to dedicated ports as the first "production" service. The succeeding phases of the low-speed service availability are being developed and the first 9600bps dedicated line connection was installed in October. Lab evaluation is underway of equipment for asynch host connection at speeds up to 38.4kbps using 56kbps synchronous digital lines with DSU/CSUs that provide synch-asynch conversion. These low-speed digital circuits are very favorably priced by Pacific Bell as part of their "Advanced Digital Network" (ADN) offering. Installation has been continuing on the MCI DS-3 microwave link that will carry traffic from BARRNet to the upgraded high-speed NSFNET backbone. The digital radios, antenna and all microwave plumbing have been installed and the balance of the equipment and activation are expected by the fourth week of November. by Bill Yundt Westine [Page 10]  Internet Monthly Report October 1990 BOLT BERANEK AND NEWMAN INC. ---------------------------- Internet Routing There now exists a complete implementation of version 1 of the IDPR protocols. After performing extensive unit testing at our respective sites - USC, SAIC, and BBN, we are currently integrating all of the software developed at the three sites. Thus far, things are working well and interoperating, including, for example, the two distinct implementations (intra-kernel and extra-kernel) of IDPR message encapsulation and forwarding. We are looking forward to testing in DARTNet, once we are satisfied with our integration tests. However, we are also pursuing alternate testing environments, in the event that DARTNet may not be ready this month. INTERNET O&M / ICBNET INFRASTRUCTURE The routing of traffic between the RSRE, STC, WPC, and NTA ICBNet nodes and destinations in the US was modified this month to use the new path provided by the 384 Kbps US/UK "fat pipe". Routing via the fat pipe path has been stable. The 64 Kbps RSRE-BBN line, which had previously provided US connectivity from those nodes, is currently scheduled for termination on 30 November. The first operational video conferences involving the new conferencing site at University College London (UCL), and routed via the US/UK fat pipe, were held this month. These included a fat-pipe Policy Steering Group (PSG) meeting held at DARPA and UCL, and an extended demonstration of video/voice connectivity to UCL from the Interop show in San Jose, CA. The TWBNet gateways and WPS were removed from the SRI site this month. This change is associated with the coming addition of a new "southern loop" to the TWBNet. SRI's ongoing IP connectivity to the TWBNet will be provided via BARRNet. Steve Storch and David Waitzman attended the ICB meetings held at SRI and RIACS on 29/30 October. Terrestrial Wideband Network and ST/IP Gateway This month, the ST Gateway and Terrestrial Wideband projects supported nine conferences and 3 days of demonstrations at the Interop Tradeshow. Seven conferences were held between two sites, two were between three sites. The RIACS site hosted its first video conferences, including a conference for the ICB Westine [Page 11]  Internet Monthly Report October 1990 (International Collaboration Board.) The Interop demonstration involved voice/video conferencing between San Jose and UCL, London. Conferees included Mark Pullen , Phil Gross, John Laws and Peter Kirstein. Meetings were held to discuss Simnet applications, ICBNet, connectivity to the UK, and various IETF working group topics. In the future months, a new "southern loop" will be added to the TWBNet. This will provide added robustness in the form of an alternate path between the east and west coasts and will also allow shorter tail circuits to Southern sites such as Ft. Rucker and Los Alamos. Current plans call for Wideband Packet Switches (WPSs) to be installed in Mobile and Albuquerque. Jil Westcott (westcott@bbn.com) CERFNET ------- Over the next few months several sites will be added to CERFnet. DIALn' CERF continues to be a popular alternative for companies with lower start-up needs. Since its installation, it has greatly increased the number and types of sites accessing CERFnet and the Internet. Local installations A 56 kilobits-per-second (kbps) link to Pepperdine University in Malibu was installed on October 25. A link to Aerojet General in Azusa was installed on October 27. The link to Aerojet was completed using an existing 56 kbps link from Aerojet to the San Diego Supercomputer Center. A 56 kbps link to the United States International University in San Diego was installed on November 1. Other sites scheduled to be installed in November and December are Santa Monica College, Fullerton College, and Loma Linda University and Medical Center. International connections In the final stages of planning are two international links to CERFnet. The Federal University of Rio de Janeiro (UFRJ) is expected to be online by February or March, 1991. The connection between CERFnet and UFRJ is intended to provide, among other things, Internet access to a regional network of research institutions located within the state of Rio de Janeiro. Initially nine institutions will be connected to this local Westine [Page 12]  Internet Monthly Report October 1990 network. These are: Brazilian Center of Investigating Sciences (CBPF), Fundacao Oswaldo Cruz (FIOCRUZ), Institute of Mathematics Pureand Applied (IMPA), Polytechnic Institute of Rio de Janeiro (IPRJ), National Laboratory of Computer Science (LNCC), Pontificial Catholic University of Rio de Janeiro (PUC-Rio), State University of Rio de Janeiro (UERJ) , Federal University Fluminense (UFF), and the Federal University of Rio de Janeiro (UFRJ). Three of these institutions (CBPF, IMPA, and LNCC) are laboratories of the National Council of Scientific Development and Technology, which is the equivalent of the National Science Foundation here in the U.S. Two are federally funded universities (UFF and UFRJ) and FIOCRUZ is the laboratory of the Federal Health Ministry. Also, the CICESE Institute located in Ensenada, Mexico is expected to be onlinein February or March, 1991. The institute will have a 56 kbps satellite link to the San Diego Supercomputer Center. Other news In October, CERFnet exhibited at the INTEROP '90 tradeshow at the San Jose Convention Center. CERFnet was awarded the INTEROP Achievement Award for the best network in the Service sector. The installation of DIAL n' CERF was completed in August. Today over 70 users are subscribing to DIAL n' CERF. In early November, POP (Post Office Protocol) will be implemented on DIAL n' CERF making it more convenient for users to receive their electronic mail. CERFnet will host the seminar, Introduction to TCP/IP Protocol Suite, instructed by Dr. Douglas Comer, on January 30-31, 1991.

ISI --- INTERNET CONCEPTS PROJECT Bob Braden organized and attended a one-day IAB meeting held in conjunction with Interop '90. He also delivered a talk at Interop on future developments in the Internet. In October, RFC-1185 "TCP Extension for High-Speed Paths", written by Braden with Van Jacobson and Lixia Zhang, was finally published. This RFC documents an extension to TCP, invented by Van Jacobson, to extend the region of TCP reliable delivery to very high bandwidths. This extension can also be used to relax somewhat the requirement for enforcement of Time-to-Live in packets. Bob Braden (Braden@ISI.EDU) Jon Postel attended the INTEROP conference and IAB meeting in San Jose California, October 7-12, 1990. Seven RFCs were published this month. RFC 1184: Borman, D., Telnet Working Group, "Telnet Linemode Option", October 1990. RFC 1185: Jacobson, V. (LBL), B. Braden (ISI), L Zhang (PARC), "TCP Extension for High-Speed Paths", October 1990.

Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT Packet multimedia conferencing made it to the InterOp show this year! With a little help from ISI, BBN put on a demonstration of the teleconferencing system in operation between the show booth and University College London and with BBN in Cambridge, MA. The demo went smoothly and was well received. This month the SPARCstation version of the packet video host, PVP, was able to run real-time video data through the HSIS board (the High Speed Interface for the S-Bus), thanks to Van Jacobson's HSIS device driver. Another milestone was that PVP and the packet voice host, VT, were able to run simultaneously in the same SPARCstation machine. In addition, PVP was extended to use not only the new method for conference initiation using the BBN Host Control Protocol, but also either of the old methods -- mimicking VT connection state or operator keyboard commands. Peter Kirstein from UCL visited ISI to learn about our implementation of the packet voice and video software. Eve Schooler attended the Computer-Supported Cooperative Work '90 Conference in Los Angeles, CA, October 7-11, and Annette DeSchon presented a seminar entitled "Overview of the ISI Multimedia Conferencing Voice Terminal (VT) Program" at ISI on October 18th. After a long time in development, the ST protocol specification was expeditiously processed by the RFC editor and has now been released as RFC 1190.

This was due to the involvement of the network staff in the large and important task of relocation and transfer of JvNCnet from JvNC to Princeton University. All the staffs' efforts, especially the collaboration between engineering, operations, and network installation and maintenance groups, assured a smooth transition and our users saw very little interruption of services. September's network availability reached 99.82%, the month we actually became settled at Princeton University and the highest availability for the year September 89 to September 90. The average uptime for the period May to Sept. 1990 is 99.40%. Traffic statistics are also provided. Availability Traffic (in Billion packets, input) May 99.50 2.3 June 99.55 2.3 July 98.88 2.6 August 99.15 2.8 September 99.82 2.9 The largest percentage of traffic increase occurred in May with 15% over April, and July with 13.4% over June and the average amount of traffic for the same five months is 2.58 billion packets. NEARnet, Princeton, Rutgers and NORDUnet have continually contributed the largest portion of JvNCnet traffic. Line utilization statistics Based on the number of days in each month, line utilization program tracks peak, average and exceeded threshold (ET). ET is the percentage of 15 minute-sample input and output of traffic exceeding the line utilization low threshold. The low threshold is established at 75% for 56 kbps line (changed to 50% starting September 1990), 15% for T1 (1.544 Mbps line), and 4% for Ethernet. These statistics are available to the JvNCnet members and indicate Westine [Page 16]  Internet Monthly Report October 1990 the high utilization for each line and offer an efficient evaluative tool for our engineering group to determine a site's performance and load on the JvNCnet and to the JvNCnet members to ascertain the need for upgrade. Network servers (NISC.JVNC.NET and R2D2.JVNC.NET) migrated to SUN 4 RISC platforms providing name server, boot server and NICOL server functions. R2D2 resides on the Sun Sparcstation and is the SNMP server as well providing the above-mentioned functions. NETMON and NETLOG, monitoring and logging applications, were installed in two Network Operations Center Sparcs along witha variety of X-based and systems resources. Ford and Zaphod EGP peers received fast- switching MCI interface cards and all routers run cisco 8.1. Charles Hedrick of Rutgers University helped the engineers to upgrade all routers to 8.1. Version 8.1 has significantly strengthened reliability and response time, while eliminating transient routing loops caused by line flaps. In order to provide transparent service to the users, duplication of the gateways (Ford, Zaphod, Hotblack, and Zarniwoop) and the NSFnet was performed and then placed in the new location. The old NSS were transferred to Princeton as the temporary NSS's replacement. Princeton now uses an Ethernet gateway. Previously under Princeton's aegis, the INRIA connection (Swiss and French Network), with direct EGP communication to the NSS, will be monitored by JvNCnet. The JvNCnet Regional Meeting was held on September 26-27, 1990 and marked the "inaugural" occasion of the JvNCnet incorporation at Princeton University. Starting the Wednesday afternoon session, President Harold Shapiro and Dr. Ira Fuchs, Vice President for Computing both welcomed everyone and chose to state how valuable and necessary researchers and scholars have for utilizing the Internet and international links as well as the significant role it plays in their daily work. Dr. David Farber presented an enlightening talk about the gigabit network, the current "experiment" at the University of Pennsylvania and its part in the NREN project. Dr. Jun Murai, Associate Professor in the Department of Environmental Information, Keio University, gave an interesting presentation about internetworking in Japan and described the research and academic networks in Japan. On Thursday, Mr. Eric Aupperle, Director of MERIT, provided an update of the NSFnet's operations and engineering plans and the relationship between DS1 and DS3 networks. Dr. Jane Caviness, the NSF Deputy Program Director discussed NSF funding issues and national and international networking. Mr. David Hochman, Acting Director of the New Jersey Commission on Science and Technology commented on the commission's positive direction in favoring network enhancement in New Jersey and achieving its ultimate goal to have every college Westine [Page 17]  Internet Monthly Report October 1990 and university in the State of New Jersey network-connected. Alan Watt, Network Manager, described the design and how Yale University utilizes the network.

Westine [Page 18]  Internet Monthly Report October 1990 MIT-LCS ------- This month the requisite wiring to support the Dartnet connection within the building is being completed and debugged. Semyon Dukach configured the local SPARC router so that its console serial line may be accessed via Kermit from a nearby Unix host. All functions of the SPARC console are thus available across the Internet. Chuck Davin (jrd@PITT.LCS.MIT.EDU) MITRE Corporation ----------------- This is a report on the past six months of Internet Engineering- related research at MITRE. OSI CONGESTION AVOIDANCE We have just completed our study of OSI congestion avoidance using the DEC bit scheme. We collaborated on this work with K.K. Ramakrishnan of DEC. In the bit scheme, the routers set a bit in the header of packets that arrive at queues whose average length is one or higher. The receiving TP4 decreases and increases the credits it gives to the sender based on the bits it receives. This scheme has been specified in the NIST Implementors' Workshop Stable Agreements. In 1989, we implemented it in the University of Wisconsin ARGO TP4/CLNP, tested the implementation in the Internet Engineering Testbed, and contributed the prototypes to Berkeley for inclusion in the BSD GOSIP release. The goal this year was to test the effectiveness of the scheme with more realistic internetwork configurations and traffic patterns. The algorithms have been simulated extensively, but with the exception of our earlier study, their internetwork performance has not been measured. We have compared the fairness, delay and throughput performance of the bit scheme with a "baseline" behavior. In the baseline, TP4 receives a fixed credit allocation of 8 PDUs, and it responds to a retransmission timeout by backing its credit down to one PDU until all outstanding PDUs are acknowledged. The experiments were: Intermittent traffic with uni-directional traffic Two-way constant demand traffic Westine [Page 19]  Internet Monthly Report October 1990 Mixed file transfer/remote login traffic Mixed TCP/TP4 constant demand traffic. As part of this task, we have also developed a TP4 module for the MIT Simulator. It includes congestion avoidance and supports mixed traffic scenarios. A technical report on the OSI internet performance experiments is not yet available for public release. Our notable general conclusion is that the DEC algorithms are effective and can be implemented efficiently (about 20 instructions in the router). We are preparing an IETF plenary presentation on the bit scheme study. TP4/CLNP will soon have regular users in the Internet and we are concerned that their implementations will not behave well facing Internet congestion. We are also working on several research and conference papers. RATE-BASED TP4 In the last half year we have extended the ARGO TP4 and CLNP in a prototype that implements the Flow Protocol defined by Lixia Zhang. The TP Connection Request Quality of Service parameters are used for the Flow Control Protocol exchanges. We have begun to analyze the performance of the prototype. The experiments were: Two-way traffic Unequal path traffic Increasing utilization Preliminary results are that Virtual Clock, the router's service discipline, is efficient in the kernel device drivers, and that the algorithms benefit performance. X.400 PERFORMANCE We have just completed a proof-of-concept prototype to test the applicability of using a full GOSIP stack in the tactical environment - an environment characterized by low bandwidth, noise, and loss. This initial study focused on low bandwidth. We ported the Wisconsin ARGO X.400 software to a MicroVaxII on the MITRE Internet Engineering Testbed. The MicroVaxII was already running the rest of the Wisconsin stack. A Testbed LANs was configured into two sections so that traffic between the sections would always be routed through gateways connected by a SLIP line. In actuality, all hosts in the test, including the gateway hosts, were on the same LAN (so we could monitor them from one promiscuous Ethernet interface and obtain one-way wire times). However, from the user Westine [Page 20]  Internet Monthly Report October 1990 and host viewpoint, each section was a separate LAN connected by a low-bandwidth transmission medium. We built an event driven message generator that used the ARGO X.400 application to send messages between hosts on each section. Experiments were run with the SLIP line having a baud rate of 600 baud and 4800 baud. The experiments were also run with and without the use of our OSI Congestion Avoidance implementation. Performance data was gathered from logs kept by the ARGO implementation, and from data gathered by the MITRE monitor program OSI trace. OSI trace, which previous to this project parsed TP4 and CLNP Protocol Data Units, was extended to parse session protocol data units and to dump 61 bytes of the application message protocol data unit. This prototype indicated that even with a low bandwidth, lower layer transmission was not a major factor in message delivery times, provided congestion avoidance was used. We concluded that given proper mail queueing and connection strategies, and the use of OSI Congestion Avoidance, the full GOSIP stack is acceptable for tactical messaging. We continue to participate in the University of Wisconsin NASA- funded X.400 Pilot project. An X.400 mail gateway is running on a Sun 3/60 in the Internet Engineering Testbed and we have exchanged messages with Wisconsin. In this Pilot, X.400 is transported over the Internet by RFC 1006 TP0 over TCP. INTERNET PERFORMANCE We presented a paper at SIGCOMM '90 on Random Drop Congestion Control. We are beginning a new project to develop visualizations of performance traces from the Testbed, and produce videos from them. We have begun a three-dimensional animation of gateway congestion control data. It is possible to see the evolution of the clustering described by Hashem in MIT/LCS/TR465. The analysis will focus on correlations of traffic by gateway queuing and effects of resource reservation and rate control on the traffic processes. Traces from our experiments with rate-based TP4 will also be visualized. Allison Mankin (mankin@gateway.mitre.org) MRNET ----- No report received.

NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NEARnet held its semi-annual user and technical seminar at BBN on October 26. More than 160 people attended. Highlights included a panel on "Introducing the Internet at Your Organization", a demonstration of user interface software, and a technical workshop on Internet security. Video tapes of the sessions are being made available; contact NEARnet for more information. A leased line to the JvNCnet was installed on October 26. This will allow NEARnet traffic to bypass the JvNCnet backbone, alleviating congestion for NEARnet and JvNCnet users and reducing the hop count between the NEARnet hub and the NSFnet backbone. This line will be in service until the NEARnet NSS is installed and accepted early in 1991. NEARnet announced that a dial-up Internet service will be available in December. The service will support email, ftp and telnet connections at 9600 baud, and will provide mail queuing and primary and backup domain service. Single hosts, terminals or networks can connect.

NSF BACKBONE (Merit) ------------------- The October 1990 count of packets coming into the NSFNET backbone totalled 5,245,630,461 packets. This total represents a 26.56% increase over the September 1990 total of 4,144,462,818 packets. As of 1 October, statistics will include traffic for NSS 18 at the Georgia Institute of Technology, Atlanta, GA. A node in the expansion of the NSFNET backbone, NSS 18 became operational at the end of September. A total of 2063 networks are configured for announcement on the NSFNET backbone as of the end of October. Statistics for nodes on the NSFNET backbone are available for anonymous ftp from the directory STATS on NIS.NSF.NET. Available data types are inpacket totals for each node on the NSFNET backbone (INPKTS), minimum, maximum and average of one-way delay times between each node on the NSFNET backbone (PING), traffic by service (PORTS), and traffic by network (TRAFFIC). Visitors to the Merit/NSFNET Network Operations Center included Osamu Takada of Hitachi Corporation, Japan, and representatives of the Deutsches Forschungsnetz (DFN).

There are now multiple paths between some sites. Generally, we prefer paths that use the T1 links. Within OARnet we have been using RIP as our IGP. This has proven inadequate because routes are determined based on hop-count (distance) rather than line speed. Another problem is slow convergence. OSPF, a link-state protocol, was developed by an IETF working group and is defined in RFC 1131. OSPF supports TOS-based routing, equal-cost multipath, tagged external routes, authentication, and area-routing. OARnet Engineering has implemented OSPF routing for the T1 backbone covering the Columbus, Cleveland, Akron, and Toledo areas. This has given us the necessary routing control to effectively utilize the T1 links. It is still necessary to run RIP in some parts of OARnet because OSPF has not been implemented by all router vendors. The borders between OSPF areas and RIP areas require careful consideration. We plan to use OSPF in all OARnet routers as soon as possible. by Lin Daniels PREPnet ------- Duquesne University joined PREPnet in October. They will be connected to the Pittsburgh hub at 56Kbps. The Whitaker Foundation has awarded PREPnet a grant to build a hub in Harrisburg. A number of the PREPnet Steering Committee members met with Al Weiss of ANS, Inc. at EDUCOM '90.

TEXAS HIGHER EDUCATION NETWORK ------------------------------ No report received. UCL ---- Further use has been made of the video conferencing facility. We have written a server to control our own video switch which can be accessed via ANSA RPC; unfortunately, this isnt compatible with existing video switch controller access which is via Sun RPC. We have started measuring the performance of the UK-US "Fat Pipe" throughput and delay characteristics, and the interaction of IP and ST on the path. We are studying the effects of resource reservation and sharing. We have (finally) installed a Rugby Radio receiver and are in the process of making our NTP on ROS talk to this device so we can offer a decent time service to the UK(GB). Steve Kille attended Interop at San Jose. Peter Kirstein chaired the ICB meeting at SRI and RIACS - a video conference was held between RIACS and UCL, and between RIACS and BBN during the meeting. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) Westine [Page 27]  Internet Monthly Report October 1990 UNIVERSITY OF DELAWARE ---------------------- 1. Thanks to long hours spent by Mike Davis, Mitch Levin and the PSI crew, our DARTNET line is now operational. We now have a working router, and line, but still have not resolved all the problems with the HSI T1 interface. We have also installed a SPARCstation on the same net as the router for use as an experiment host. 2. A fuzzball time server originally from JvNC has been refurbished with hard disk and configured for operation at the MIT NSS when installed. This will have a WWVB timecode receiver and serve the NEARNET populace. Several new public time servers have popped up in the US, UK, FRG and Australia. Details can be found in the file pub/ntp/clock.txt on louie.udel.edu. 3. Our fancy cesium clock lost tick and was replaced courtesy of the US Coast Guard, who along with US Naval Observatory have been most supportive or our timekeeping activities. Some analysis of how to improve time-transfer for DARTNET and our high-speed network now in design suggests the use of a LORAN-C receiver and disciplined quartz oscillator. Although this scheme is in use now here and at NTARE in Norway, commercial LORAN-C receivers are much too expensive for casual use. A design for an inexpensive LORAN-C receiver as an IBM PC parasite has been completed and is now under construction.
