The following decisions and indecisions resulted. A. Open IGP The IAB considered whether it is still appropriate to select a single standard Interior Gateway Protocol, with the hope and intent of universal implementation in vendor gateways. There is considerable technical and political ferment surrounding this issue at present; as a result, the IAB decided to defer a decision on this matter. This deferral should not impede development and standardization of any particular candidate open IGP. In particular, the IAB reaffirms that the OSPF[IGP] protocol, designed and currently being prototyped by a Working Group of the IETF, is on the track for future standardization as an open IGP. B. IESG and Standards The IAB decided that the success of the recent reorganization requires that the IESG (Internet Engineering Steering Group) play a key role in setting Internet standards. Therefore, the standard-setting loop has been enlarged to include the IESG, which will make recommendations for final action by the IAB on requests to designate Draft Standards and Standards. C. RFC's in Postscript The IAB has noted the intense concern in the community about Postscript-only RFC's; unfortunately, there is no ideal solution for this problem. Until ODA or its equivalent is widely available, some combination of ASCII and Postscript is the best we can do. The IAB has instructed the RFC Editor to obtain an ASCII version from the author of any Postscript-only document whenever possible, and both versions are to be made publicly available. Although the dual versions may cause significant extra work for both authors and editor, this appears to be the only feasible compromise. Westine [Page 3] Internet Monthly Report October 1989 INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- Since the work in Policy Routing has shifted largely to the Open Routing Working Group (of which many of us are members), ANRG is in the process of investigating several new work areas for this next year, e.g., charging, fault isolation, and inter- administrative domain application level relays. Deborah Estrin (Estrin@OBERON.USC.EDU) END-TO-END SERVICES ------------------- No internet progress to report. Bob Braden (Braden@ISI.EDU) PRIVACY AND SECURITY -------------------- The Privacy and Security Research Group met on 24-26 October 1989 at Hanover, NH. There were presentations and discussion of draft papers by Michael Roe on "Standard Interfaces to Cryptographic Functions" and Dave Solo on "Secure Gateway Routing". Guests Noel Chiappa, an IETF area director for Internet based services, and Scott Bradner, designer and manager of Harvard High Speed Data Network, discussed with the PSRG Internet Router requirements with the PSRG that relate to security issues. Comments concerning the recently distributed Privacy Enhanced Mail RFCs 1113, 1114, 1115 were discussed. Some minor corrections and clarifying suggestions were noted and are expected to be incorporated into a future version of the RFC's. Steve Kent and Dave Balenson of the PSRG were speakers at Interop 89 in a session on Secure Electronic Mail. Steve Kent chaired the workshop on Commercial IP Security Options which had 12 participants, many from the PSRG and industry. Papers were presented on the use of CIPSO for policy routing and other security services. Westine [Page 4] Internet Monthly Report October 1989 In a joint implementation effort by BBN, TIS, and RSADSI the PSRG expects to distribute to its members a Phase I implementation of Privacy Enhanced Mail compliant with RFCs 1113, 1114, and 1115. Lyndalee Korn (lkorn@BBN.COM) USER INTERFACE -------------- No report received. INTERNET ENGINEERING REPORTS ---------------------------- 1) The IETF will meet on 30 Oct - 4 Nov at the University of Hawaii. The meeting will be hosted by Torben Nielson (UH) and NASA. The agenda for the meeting is included below. Highlights include 19 working groups meeting, an open steering group meeting, a focus on Pacific rim network connectivity, and a report by Marshall Rose on the Nysernet White Pages Pilot Project. 2) Some current WG status The OSPF WG has finished its work and submitted the OSPF specificiation for publishing as an RFC. (Now published as RFC 1131, Postscript format). The PPP WG has essentially concluded its work, with a final Internet-Draft and demo at Interop '89. Russ Hobby has developed a PC version of PPP under the KA9Q package, and Drew Perkins has developed a version for 4.3 bsd. The PPP specification has been split into two documents. The main document contains the encapsulation scheme and the specification for the Link Control Protocol (LCP). Negotiable options used by the LCP are defined in a second document. The main PPP specification was submitted for publishing as an RFC at the IETF meeting. Please contact Russ Hobby (rdhobby@ucdavis.edu) or Drew Perkins (ddp@andrew.cmu.edu) directly for information about their openly-available interoperable packages. 3) The IETF steering group (IESG) met briefly October 4th at Interop '89. Issues included: o Future IETF Meetings - A suggestion to reduce the number of IETF meeting from four per year to three per year was favorably received. This would help reduce the overall travel burden. Westine [Page 5] Internet Monthly Report October 1989 It was hoped that WGs could use the additional time to meet between IETF meetings via video teleconference. It will take almost a year to begin implementing this suggestion because we are currently scheduled out through summer 1990. o Working Group management and Area planning - Area Directors are beginning to take a direct role role in managing the activities of WGs in their areas. We discussed the need to sharpen up the focus of some existing WGs, and also discussed the need for creating other specific WGs. This is a continuing topic that will be discussed at the IESG meeting in Hawaii. o Multiple standard IGP's - There is interest in forming a new WG to develop a specification for an Open Distance Vector Routing Protocol. This opens the question about having multiple standard IGP's. The general feeling of the IESG was that while multiple standards are possible the preference would be a single standard IGP implemented by all router vendors. No decision was reached and it was recognized that any decision will have to be carefully deliberated. This will be discussed again at the IESG meeting in Hawaii. In any case, the final decision rests with the IAB. The IESG will simply make a recommendation. o Format of future IESG meetings - All IESG meetings will be open, with some possible executive sessions. The agenda and minutes of all IESG meetings and executive sessions will be made available online and in the Internet Monthly Report. 4) The agenda for the next IESG meeting follows. The meeting will be Thursday November 2nd (9am-noon). o Emphasize open meeting and reporting policy (10 minutes) - Open meetings; some executive sessions - Progress reported in Internet Monthlies and IETF mailing list o OSF Report - Craig Partridge (10 minutes) o PPP Report - Phill Gross (10 minutes) o Routing Area (60 minutes) * IGP Issues and policy - Discuss timing and immediacy of IGP - Explore alternative decisions - Set date for decision - Set milestones and deadlines * BGP, EGP3, IWG * Routing Architecture o Working Group Management (60 minutes) - Review current and proposed WGs - Continue delegation from IETF Chair to Areas Westine [Page 6] Internet Monthly Report October 1989 - Better tracking of WG activity (milestones/deadlines) - Prepare for lunch with WG chairs - Future reporting (Friday morning; Internet Monthly) o Future Planning (10 minutes) - February as Protocol Evolution Workshop? o Ad hoc topics Minutes of this meeting will be in next month's Internet Monthly Report. 5) The agenda for the October 30 IETF meeting is below.

BOLT BERANEK AND NEWMAN INC. ---------------------------- INTERNET RESEARCH Most of this month was spent on the architecture RFC. We have identified the key functions of the protocol (the ES-VG part and the VG-VG part), the agents that will execute these functions, where these agents should be located, and some details of the protocol. In the VG-VG protocol we have identified the information that goes into the update, which of the two AD pieces send out what part of this data, what the route servers should do with the dynamic information, and the election of the speaker for the VG (which can consist of several physical forwarding boxes in two different ADs.) We are still concentrating on the VG-VG and the data dissemination functions. TERRESTRIAL WIDEBAND NETWORK AND ST/IP GATEWAY During October, The Terrestrial Wideband continued to support cross-country multi-media conferences. Dr. Barry Boehm, Director of DARPA ISTO, held an ISTO staff meeting on October 2 and has scheduled one for October 30. Other conferences were held by the "Forward Edge of the Battle Group" on October 5, and the "Collaborative Effort on Environments" group on October 6. The version of the IP gateway with ST protocol support and the real-time performance attributes described in last months status report was fielded this month at the four Terrestrial Wideband Net sites currently supporting packet-switched video teleconferencing. On 10/26, the Pittsburgh WPS was installed and brought up on the network. There was a problem with the tail circuit, so the CMU gateway has not been connected to the WPS as of the date of this report (10/27). However, it is up and connected to the local ethernet. Westine [Page 10] Internet Monthly Report October 1989 INTERNATIONAL COOPERATION BOARD (ICB) INFRASTRUCTURE The Butterfly gateway at SHAPE Technical Centre was installed, and connected to the 64KB line that connects to RSRE. Hosts on the ethernet are being configured and registered by the site, and are enjoying their new-found throughput. BBN/Slate and MMConf software has been delivered to SHAPE Technical Centre and installed on the DARPA provided SUN system. Demonstrations of the document handling and conferencing capabilities will be done for local site people, so that they may begin exchanging these documents with people in other groups in the ICB. Bob Hinden (Hinden@BBN.COM) CERFNET ------- Installations A 56 kilobits-per-second (kbps) link to Occidental College in Los Angeles, was brought up on the network on October 23. Occidental is connected to CERFnet via the Caltech backbone node. Also, the Communications and Data Processing Division of Hughes Aircraft moved their 56 kbps CERFnet connection to Fullerton on October 28. Hughes is now connected to CERFnet via the UCI backbone node. Two new sites will be brought up on CERFnet over the next two months. A division of Xerox Corporation located in San Diego, will be brought up on November 29. Science Application International Corporation, San Diego, will be brought up on December 14. Technically Speaking CERFnet experienced problems with EGP neighbors at the San Diego Supercomputer Center from about 18:30 pdt October 16, to about 9:30 pdt on October 17. This caused the SDSC cisco boxes to stop working at various times throughout the night. The EGP processes that caused the problems were discovered and stopped shortly after software personnel arrived in the morning. During the outages CERFnet traffic was denied access to the NSFNET. UC Santa Barbara's (UCSB) cisco box continues with its Ethernet storms and its link outages. CERFnet operations staff have to login via UCLA and clear the interface on the UCSB cisco box in order for it to restart. The MCI card in UCSB's cisco box will be replaced on October 30 in attempt to resolve this problem. Westine [Page 11] Internet Monthly Report October 1989 Administration The CERFnet Plenary board met on October 24 to discuss CERFnet related issues. Items on the agenda included Fiscal Year 1989 achievements, Fiscal Year 1990 goals and budget, staff introductions, dial-up service to CERFnet, FARNet and IETF reports. The October-November issue of CERFnet News was distributed via electronic mail and hard copy. Articles in this issue include; FDDI, CERFnet Report, SNMP and CERFnet, Internet Accessible Library Catalogs and Databases, Internet Notes. The current issue of CERFnet News and back issues are available via anonymous ftp to sds.sdsc.edu in the subdirectory [.cerfnet_news]. The filenames are in the format Month-MonthYear.txt, for the text only version, and MonthMonthYear.ps, for the postscript version. by Karen Armstrong (armstrongk@sds.sdsc.edu) CICNET ------- CICNet has been active in a variety of areas during the past month. These include the addition of two new Computer/Telecommunications members, further progress on the physical reconfiguration of our backbone network to ensure greater facility survivability, the implementation of our Video Applications Study Group, and the demonstration of a PC/Fax hybrid for library applications. Effective at the September meeting of the CICNet Board of Directors, Network Equipment Technologies (NET) and LiTel Telecommunications 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. At the present time, there are more than thirty new member prospects under consideration, including universities, nonprofit organizations, and corporations. To accommodate this growth, CICNet has a Marketing Manager position currently open. MCI has successfully reconfigured key portions of the CICNet backbone facilities, making them more geographically independent, and therefore less likely to be compromised by a single point of failure. CICNet's Video Study Group will meet November 9, 1989 in Ann Arbor to evaluate the various types of video applications and solutions that might be appropriate over our network. Participants will Westine [Page 12] Internet Monthly Report October 1989 include end users, networking groups, and vendors. Topics will cover actual applications, video technologies, and video networking issues. 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 will be assisting in the deployment of the project. by Joel Maloff (Joel_Maloff@um.cc.umich.edu) CORNELL ------- No report received. ISI --- INTERNET CONCEPTS PROJECT Bob Braden attended the Interop '89 meeting to participate in a session on the Host Requirements RFCs and to attend a one-day IAB meeting. He has been helping to organize internet experiments that could make use of a T1 testbed built on the DRI lines. He also completed a new release of the NNStat package, incorporating a number of important extensions: support for the Sun 4 hardware, support for a PC RT, access control, and subnet support. Greg Finn continued the development of the IP Source Quench implementation. Jon Postel attended the IAB meeting and Interop '89, in Santa Clara, CA, 3-6 October. Jon Postel attended Cerfnet meetings at SDSC, October 24, 1989. Nine RFCs were published this month. RFC 1122: Braden, B., "Requirements for Internet Hosts -- Communication Layers", USC/ISI, October 1989. RFC 1123: Braden, B., "Requirements for Internet Hosts -- Application and Support", USC/ISI, October 1989. RFC 1124: Leiner, B., "Policy Issues in Interconnecting Networks", RIACS, October 1989.

Ann Westine (Westine.ISI.EDU) MULTIMEDIA CONFERENCING PROJECT Last month we tested Compression Labs and PictureTel video codecs across the packet video system between ISI and DARPA. This month we completed our planned three-way test when we used VideoTelecom codecs during the third ISTO staff meeting teleconference. Audio was carried through the video codec as well, using the built-in echo cancellers so no headphones were required. The packet video host, PVP, was released in a new version which provides more diagnostic information and more flexibility in adapting to various video codec frame sizes. This month there were several features added to the MBFTPTOOL. We completed the implementation of "dot-files", which will enable MMConf to determine whether or not a file placed in the conference directory needs distribution to the other conference participants. In addition, we are experimenting with a new user interface feature where "hints" are provided to make it easy for the user to determine which parameters must be explicitly entered. Steve Casner attended the User Interface Research Group meeting at BBN. Steve Casner, Annette DeSchon, Dave Walden, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU) Westine [Page 14] Internet Monthly Report October 1989 FAST PARTS Alan Katz continued work on a mail based FAX server and did some work on his remote execution protocol, T.REX. Alan Katz (Katz@ISI.EDU) JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK --------------------------------------------- The major events of September can be summarized as follows: (i) traffic volume, (ii) JvNCNet Phase II update, (iii) network seminars, (iv) regional network meeting. The overall up-time for the network this month was 98.54%, which is higher than last month (97.99%). The total amount of traffic for the month was 1,257,314,946 packets, of which NSFnet/JvNCnet traffic amounted to 42%. The JvNCnet Phase II backbone continues to grow in number of sites. This month (September) we added NEARnet and NYU to the Phase II backbone, these two sites were previously connected to the JvNCnet network. These connections were made with the one-week overlap procedure allowing for a duplication of services for one week to have a smooth transcition between the old network and the new one. An acceptance test is being developed, and will be utilized to declare a new site operational, which internally means the transfer of control from the Network Installation and Maintenance Group to the Network Operations Group. A Network Seminar was held on September 7 at JvNC. The purpose of these seminars is to foster dialogue among the network community, selected vendors, Center's staff and distinguished members of the National Research Networking community. The September 7 seminar had as a topic the "JvNCnet Phase II network". There were presentations from the Rochester Telecommunications Company's president and product manager, Cisco Systems and JvNC. A Regional Network meeting was held on September 8 at JvNC. The status of the network was discussed during the morning. In the afternoon there were two presentations, one on "Bitnet II" from Peter Olenick (Princeton University), and the second one on "Integrating Heterogeneous Campus Mail Systems" from Stephen Campbell (Dartmouth College). The next Regional meeting will be in January 1990.

Los Nettos has had a number of billing errors in T1 line bills received from both Pacific Bell and GTE. Some of the errors have been due to incorrect initial assumptions on installation. The other type of error we have seen is a failure to change the billing rate after a tariff change. We have learned that it is critical that initial bills and bills after tariff changes be closely inspected. In order to make critical inspections of the bills it is further necessary to fully understand the component costs making up the monthly rate. Further, circuits going between PacBell and GTE are prone to being incorrectly billed. All of our circuits are intra-LATA presumably making things simple. Pacific Bell has been quick to resolve the billing problems but GTE has not. Our SNMP based route monitoring tool is proving valuable for quickly showing problems which would affect performance and reliablility but not connectivity. Thanks go to cisco and the NSFNET for implementing SNMP in their gateways, and to MIT for making their SNMP client software available.

MITRE Corporation ----------------- No report received. MRNET ----- Work continues on upgrading MRNet's link to the NSFnet backbone to a T1 circuit. In fact, the ciruit itself has been installed. However, all of the rest of the approvals, equipment purchases, and installation remain. Nonetheless, I expect the upgraded MRNet link to be operational in November. Jeff Wabik, Technical Chair of MRNet, met with the ten Minnesota private colleges to review their plans for connecting to MRNet. The colleges should connect to MRNet in the next few months. The MRNet Executive and Technical Committees continue to work on plans to connect the Minnesota State University System to MRNet and the Internet. by Timothy J. Salo (tjs@msc.umn.edu) NCAR/USAN --------- No report received. NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NEARnet added Clearpoint Research Corporation to the network during October. Operation of the network continued to be stable. by John Rugo (jrugo@bbn.com) Westine [Page 18] Internet Monthly Report October 1989 NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Craig Partridge gave a presentation on Internet Networking at the NORDUNET Conference in Stockholm, Sweden. Karen Roubicek and Craig Partridge moderated panels at the Interop-89 conference in San Jose. The NNSC distributed revisions to Chapters 1 and 2 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 Karen Roubicek (roubicek@nnsc.nsf.net) NORTHWESTNET ------------ No report received. NSF BACKBONE (MERIT) ------------------- Traffic on the Backbone During September 1989, NSFNET traffic reached 1.6 billion packets. This represents an increase of 9% over August 1989, and an increase of more than 500% since September 1988. In addition, as of 9/30/89 total network connections stand at 836. InterOp '89 Several representatives of Merit/NSFNET attended the InterOp conference held in San Jose during October. In particular, Susan Hares gave a presentation on Policy Based Routing and David Katz demonstrated prototype implementations of OSI and FDDI. In the OSI implementation the NSFNET backbone provided OSI Intermediate System functionality for the ISO Connectionless Network Protocol ("ISO IP"). The exhibit illustrated wide area connectivity between OSI LANs as well as End Systems. Packets were carried across a T1 link between the InterOp OSI Demonstration Network in San Jose and an OSI network in Ann Arbor, Michigan. As NSFNET today is primarily a TCP/IP network, the prototype OSI implementation is designed to coexist with the existing network architecture. Both DoD IP and OSI packets are forwarded together Westine [Page 19] Internet Monthly Report October 1989 through the same packet switches and links. Fully dynamic routing is supported for both protocols, providing automatic rerouting in case of an outage. The FDDI (Fiber Distributed Data Interface) implementation was intended to demonstrate TCP/IP networking between local and long- haul networks using FDDI. As cross-country bandwidth increases, high-speed technologies such as FDDI will become important as an access media to local networks. Monthly Packet Counts Available A new directory has been added to the NSFNET Information Services remote query database. The directory 'stats' contains monthly packet counts for each of the 13 backbone nodes. The files are available through anonymous ftp to spreadsheet programs for further analysis. For further information send electronic mail to 'nis- info@nis.nsf.net' or 'nis-info@merit' (Bitnet). EDUCOM NSFNET's accomplishments and its ongoing commitment to the development and use of a nationwide computer networking system were subjects of keen interest at the recent EDUCOM '89 conference held in Ann Arbor, MI. Special interest groups conducted by Merit/NSFNET staff on national and campus networking drew overflow crowds. Merit/NSFNET staff also presented an introduction to the Internet for conferees. An unexpected use of the NSFNET occurred when the earthquake struck California on October 17. Because of the disruption of conventional voice communications the many California residents attending the conference quickly turned to the network in order to communicate with relatives and friends back home. Service to backbone nodes in Palo Alto and Seattle was uninterrupted during this time. All-in-all the combination of EDUCOM and Mother Nature provided an exciting week of activities for Merit/NSFNET staff. by Patricia G.

PREPNET-Pennsylvania Research and Economic Partnership Network -------------------------------------------------------------- PREPnet added U.S. Steel Research as a new member during October. On October 12, PREPnet held its first meeting of general members in Harrisburg. Although the PREPnet Steering Committee, comprised of representatives from the charter institutions, Bell of Pennsylvania, and the Commonwealth, has been meeting monthly for more than a year, this was our first opportunity to assemble the entire PREPnet community, including our new members and affiliates, and some prospective members. Nearly sixty people were present, representing most of the current membership and about a half dozen prospective members, as well as Bell and the Commonwealth. Thomas W. Cummings PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- PSC would like to welcome Wendy Huntoon to our networking staff. She will be taking on production communications programming at PSC. Our side door with SURAnet has been phased out due to bugetary constraints. While it was operational it was used heavily, both as a direct path between PSCnet and SURAnet and as a full backup for our NSFnet connectivity. It is believed to have been the first and possibly only true fully symmetric side door implemented between two mid-level networks. Both of our ARPAnet ports were officially scheduled down on October first. Our internal routing has been substantially re-engineered, and we are now using the NSFnet for our our default route. In addition we are no longer carrying any NSFnet <-> ARPAnet transit traffic. by Gene Hastings (Gene.Hastings@boole.ece.cmu.edu) Westine [Page 21] Internet Monthly Report October 1989 SAN DIEGO SUPERCOMPUTER CENTER ------------------------------ No report received. SESQUINET --------- No report received. SRI ---- In October, we have assigned 49 new numbers for government- sponsored connected networks. In addition, we assigned 72 numbers this month for unconnected IP networks. The total number of all assigned IP networks is now 3,438 which includes 1,952 connected networks and 1,486 unconnected networks. The total number of assigned Autonomous System numbers (ASNs) is 544. There are currently a total of 1,214 registered domains which includes 44 at the top level, 1,170 at the second level, and 38 third-level MIL domains. Douglas MacGowan (MacGowan@NIC.DDN.MIL) SURANET ------- SURAnet continues to increase in the number of sites connected and in the number of networks advertised to the NSFnet. At present there are 70 sites online and 99 networks are being advertised to the NSFnet. The current list of sites and networks can be obtained via anonymous FTP from noc.sura.net, password guest, cd pub. File name is "online". by Jack Hahn (hahn@umd5.umd.edu) TEXAS HIGHER EDUCATION NETWORK ------------------------------ No report received. Westine [Page 22] Internet Monthly Report October 1989 UCL ---- Work on porting the X Protocol to run over the ISODE implementation of the Transport Service is underway. The initial mapping is fairly direct. The main purpose is to allow the use of X Windows over (TS+) X.25 nets, and with the help of Transport Bridges, between TCP and TS+X.25 nets. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Paul Schragger's gigabit network scheduling simulator tool is being reviewed for possible redesign. Besides its application to non-slotted systems, we would like to use it also for the exploration of slotted systems. Mike Davis is working on correlation methods to analyze network behavior during periods of congestive stress and presented a departmental seminar on SNMP. Ken Monington is reviewing principles of time synchronization and expects to participate with NTARE and others in wide-area synchronization experiments. Erik Perkins is reviewing documentation and preparing plans to participate in RIG-related experiments. Dave Mills presented an interdepartmental seminar on the Internet and a briefing on high-speed network scheduling at USENIX. 2. We have connected the dcn1.udel.edu fuzzball NTP time server to a cesium standard providing time to less than a millisecond independent of outside (radio) reference. The time offset is calibrated as best we can using existing radios; however, we expect to reduce the errors when LORAN-C radios arrive next month. Paal Spilling at NTARE (Norway) now has fuzzballs operating and expects to duplicate the setup. 3. Two additional documents on NTP have appeared, RFC-1129 describing the concepts and principles of network time synchronization and RFC-1128 discussing the results of the glorious NTP experiments of last Summer, both sprinkled lavishly with figures, graphs and tables for PostScript lasers.

WESTNET -------- 1. The T-1 line between New Mexico Technet and NCAR is still being tested. We are running this line in parallel with the 56 kbps circuit until we become convinced of stability. 2. The annual Westnet Technical workshop will be held from Nov. 15 through Nov. 17, 1989 at the University of Colorado at Boulder. Thanks to all of the NSF Phase II Sites who sent information to be distributed. Thanks also to MERIT, MCI, NNSC and cisco who will be sending speakers. by Pat Burns (pburns@csupwb.colostate.edu) Carol Ward (cward@spot.colorado.edu)
