[IMR] IMR89-02.TXT FEBRUARY 1989 INTERNET MONTHLY REPORTS ------------------------ The purpose of these reports is to communicate to the Internet Research Group the accomplishments, milestones reached, or problems discovered by the participating organizations. This report is for research use only, and is not for public distribution. Each organization is expected to submit a 1/2 page report on the first business day of the month describing the previous month's activities. These reports should be submitted via network mail to Ann Westine (Westine@ISI.EDU) or Karen Roubicek (Roubicek@NNSC.NSF.NET). TASK FORCE REPORTS ------------------ APPLICATIONS -- USER INTERFACE No report received. AUTONOMOUS NETWORKS The ANTF held a productive meeting February 14-16 at ISI. During the first two days we were joined by several members of the IETF ORWG. We spent much of the first day articulating the context in which policy based routing will be implemented and the problems that it needs to solve. The second day was spent detailing our agendas and discussing several of the individual projects specified (see upcoming ANTF meeting report for details). In addition we discussed two particular routing Westine [Page 1]  Internet Monthly Report February 1989 proposals, one by Dave Clark on Policy based routing for the Internet (soon to be published as an RFC), and one by Greg Finn on Cartesian Routing (available thru ISI). The third day of the meeting was held in conjunction with the Privacy and Security Task Force. During the first half of the day we addressed labeling and security in policy routing protocols. The second half of the day addressed the more general topic of denial of service attacks on routing protocols. A more detailed report on the meeting will be available shortly from me (greatly assisted by the meeting notes taken by Sharon Anderson). Deborah Estrin (Estrin@OBERON.USC.EDU) END-TO-END SERVICES VMTP: o The Unix kernel implementation of VMTP was released to the world November 1988. Several fixes and extensions have been added since. o There will be an article on VMTP in an upcoming issue of the IEEE Communication magazine, in an edition on high- performance protocols. o A version of X11 Mazewars is running at Stanford using VMTP and multicast. They are still modifying it, but hope to release it in the next few months. o Dave Cheriton has presented VMTP to ANSI committee X3S3.3, proposing it as a possible standard. IP Multicasting: o Steve Deering has been debugging and improving the RIP- based multicast router developed at BBN and described in RFC-1075. He expects to release it very shortly. o Berkeley has not yet released the IP multicast host code; it is currently scheduled for BSD 4.4. o Craig Partridge and others at BBN are writing up a comparison of the distance-vector-based and SPF-based multicast routing protocols done at BBN. Westine [Page 2]  Internet Monthly Report February 1989 o Discussions are underway with the Open SPF IGP (OSPFIGP) Working Group of the IETF, concerning the possbible inclusion of SPF-based routing in their protocol. Bob Braden (Braden@ISI.EDU) INTERNET ARCHITECTURE At the December IAB workshop and meeting in Santa Clara, it was suggested that INARC take up the issue of the limits of the Internet architecture and protocols in the light of present and projected future requirements. A meeting has been proposed for the May/June frame at a date and place to be decided. The meeting is to be organized as a workshop similar to the one held a year ago. Participants will be encouraged to present a prepared talk and/or document, but this is not a requirement for admission. While participants may be invited on the basis of their known expertise, biases and vocalities on the issues, participants outside the IAB and its dependencies are actively encouraged. Following the workshop the INARC will meet specifically to discuss issues raised and to determine future study plans and assignments. Suggestions for agenda items and meeting date and place, as well as intentions to attend, can be sent to the chair at mills@udel.edu. The meeting date and place will be announced in the INARC report for next month. Dave Mills (Mills@HUEY.UDEL.EDU) INTERNET ENGINEERING 1. The next meeting of the IETF is April 11-14 in Cocoa Beach Florida. The meeting will be hosted by Kennedy Space Flight Center, although the actual meeting site will be the Cocoa Beach Hilton. KSC is planning an extended tour of the Space Center facilities on Friday afternoon (April 14th). 2. As a direct response to discussions in the January IETF Plenary session, the April meeting has been scheduled for 3.5 days. This will allow time for 2 full days of Working Group sessions, 1 full day of technical presentations, and .5 days for WG reports. The final agenda for the April meeting is still being compiled. Westine [Page 3]  Internet Monthly Report February 1989 3. Meeting information (eg, hotel, directions) has been mailed to the IETF mailing list.

PRIVACY The IAB Privacy Task Force had a productive three-day meeting at USC/ISI in Marina del Rey, California on 14, 15, and 16 February 1989. Privacy task force attendees were: Dave Balenson (now representing TIS), Matt Bishop, Morrie Gasser, Russ Housley, Steve Kent, John Linn, Jim Nechvatal (new NIST representative), Dan Nessett, Rob Shirey, and Dave Solo. The first two days were devoted to Privacy Task Force discussion. We addressed final revision issues on the electronic mail privacy enhancement RFCs, including a decision to split off a new "Privacy Enhancement for Internet Electronic Mail: Part III: Algorithms, Modes, and Identifiers" and to defer detailed certificate ordering information to a later follow-on RFC. Ralph Merkle of Xerox PARC gave a presentation on a family of new encryption and hash algorthms which he has designed and offered for consideration. The session on the 16th was held as a joint meeting with the Autonomous Networks Task Force, discussing policy routing issues and other topics of mutual interest. Westine [Page 4]  Internet Monthly Report February 1989 The next PTF meeting was tentatively scheduled for 23-25 May at UCL, subject to reconfirmation with Steve Wilbur. Dartmouth College is a possible venue for the following meeting, probably in October. John Linn (Linn@CCY.BBN.COM) SCIENTIFIC REQUIREMENTS No report received. DSAB ---- No report received. Westine [Page 5]  Internet Monthly Report February 1989 BOLT BERANEK AND NEWMAN INC. ---------------------------- WIDEBAND NETWORK A message describing transition plans for the Wideband Network was distributed on February 15 by Mark Pullen of DARPA/ISTO. It is included below for the benefit of the Internet research community. TO: Widebandnet Sponsors and Users FROM: DARPA/ISTO SUBJECT: Transition of Widebandnet to Fiber Backbone As described in my previous message of 12 July 1988, the satellite carrier's contract for Widebandnet is at an end and the net is being transitioned to a fiber-optic T1 backbone, as the first operational component of the Defense Research Internet. It is recommended that users of Widebandnet plan minimum reliance on the net during the months of March and April, 1989. The Widebandnet transition is being coordinated with the installation of a number of cross-country terrestrial T1 circuits which will create a new National Networking Testbed (NNT). The creation of the NNT is an initial step towards the establishment of the Defense Research Internet (DRI). Among other applications, NNT bandwidth will be used to provide continued support for both the internetwork and ARPANET inter- switch trunk (IST) traffic that is now carried by the Widebandnet. The internetwork traffic will be serviced by a newly designed terrestrial coast-to-coast network consisting of high-speed Butterfly switches linked via a multidrop NNT T1 circuit. The ARPANET IST traffic will be serviced by 56 Kbit/s trunks to be derived from a separate NNT T1 circuit. The Widebandnet transition will commence on or shortly after 1 March 1989, when satellite channel access will be terminated for four Wideband earth stations: M/A-COM Government Systems in San Diego, CA; US Army CECOM in Ft. Monmouth, NJ; Carnegie Mellon University in Pittsburgh, PA; and Ft. Huachuca, AZ. (The latter two of these sites have not been active on the network for some time.) Channel access for the six remaining earth stations (ISI, Lincoln Laboratory, DCEC, SRI, RADC, and BBN) will be terminated in the early April time frame. The exact date for final Widebandnet operation will be a function of progress made in transitioning the Wideband-based ISTs to the NNT. As the Westine [Page 6]  Internet Monthly Report February 1989 transition approaches, cutover schedules will be provided. The high-speed NNT-based network will ultimately provide a level of service and functionality to its users exceeding that which has been provided by the satellite-based net. Hardware/software interfaces to the new network will initially be the same as those currently used in Widebandnet and, other than a reduction of network message delays due to the elimination of satellite- channel propagation, users of the standard connectionless Widebandnet "datagram" service should notice little change in their wide-area networking support. Initial operation of the terrestrial network is scheduled for the April time frame. By 1990 we expect to be offering various high-speed packet services in the DRI. At that time the network interfaces are likely to change. Even with the best of planning, a change such as this necessarily entails some amount of disruption and temporary loss of service. We solicit the patience of current Widebandnet users during this transition period as we move closer to the achievement of the high-speed research network environment of the future. Mark Pullen SATNET SATNET performance was excellent during February. Statistics collected by ISI showed an average of 100% uptime for the SIMPs and 99% uptime for the attached European gateways. The SATNET connection to the UK (Goonhilly) has been terminated on paper but at this time is still operating. It is expected the connection will be turned off physically some time in March. This will leave only the U.S. and Italy operating on the SATNET. The new direct link to Italy is expected to be operational in April at which time the SATNET will be completely turned off. INTERNET R&D The Internet continues to grow. At the end of February there were over 640 networks in the Internet. We have started working on deploying new Butterfly Gateways at SHAPE Technical Center in The Hague, and at WPC in West Germany and additional Butterfly Gateways at UCL and RSRE. These will be part of the European DRI. We have also started working on deploying three Butterfly Gateways for SURAN sites (two for Ft. Monmouth, one Westine [Page 7]  Internet Monthly Report February 1989 for SRI). The IETF Open Routing Working Group meet in February at ISI. Bob Hinden (Hinden@BBN.COM) CORNELL UNIVERSITY ------------------ Scott Brim has been working on projects in the IETF Interconnectivity Working Group and the Autonomous Networks Task Force (q.v.). Among other things he has been developing plans for near-term steps on the way to full policy-based routing, working out specifics for policy-based routing experiments with the RIGs, and defining interactions between the components of a policy-routed network, within and between administrative regions. GATED: This month the gatedaemon underwent a lot of internal reorganization for improved operation and as a large step toward modularity and ease of adding new protocols. Interdependence between protocols was reduced to the point where it should be possible to select which protocols should be included at compile time. As part of being redesigned for modularity, gated's timing routines have been rewritten to be more general and more accurate. This will also prevent synchronization of routing updates on broadcast protocols such as RIP (the "boxcar" effect). Also rewritten were the gated tracing and logging facilities, now combined into one routine which logs to the trace file and/or the system log depending on arguments passed. Gated's EGP2 implementation was completely rewritten to comply explicitly with RFC904. The previous code deviated from the RFC in many respects. The new implementation is a more formal implementation of a state machine and should provide a good base for EGP3. It has also provided us with a better understanding of the EGP2 protocol and uncovered a couple of glitches in RFC 904. This implementation has also uncovered a few bugs in the Butterflies which have been reported to BBN. Testing has just begun against Proteon's EGP implementations and we hope to set up a test with other routers as well. On gated's near-term list of things to do are: * generalizing the event-driven update system. Westine [Page 8]  Internet Monthly Report February 1989 * redoing the command syntax and parser to make adding newer protocols and experimenting with policy-based routing prototypes easier. * EGP3 (as soon as the specifications are ready). Along with this we will be reorganizing the routing database, keeping multiple routes, and conceptually treating the system kernel as another gateway to which we give selected information. * OSPFIGP. * SNMP traps, configured per community and per interface, per list of recipients. Jeff Honig and Scott Brim (swb@chumley.tn.cornell.edu, jch@devvax.tn.cornell.edu) ISI --- INTERNET CONCEPTS PROJECT The basic IP congestion control algorithm assumes no new functionality on the part of gateways. Simulation results indicate that congestion is well controlled but resources are often unfairly split between multiple competing sources. A modificationm that assumes that gateways return source quenches for packets drawn at random from their overflowing queues, rather than always returning a source quench for the packet that caused the overflow, appears to improve fairness. This is being studied. Greg Finn Jon Postel visited Digital Sound Corporation in Santa Barbara, to discuss networks. Paul Mockapetris attended the FRICC White Pages Working group Meeting, in Washington, D.C, February 6 and 7. Six RFCs were published this month. RFC 1088: McLaughlin, L., "A Standard for the Transmission of IP Datagrams over NetBIOS Networks", TWG, February 1989. RFC 1089: Schoffstall, M., C. Davin, M. Fedor, and J. Case "SNMP over Ethernet", February 1989. RFC 1090: Ullmann, R., "SMTP on X.25", February 1989. Westine [Page 9]  Internet Monthly Report February 1989 RFC 1091: VanBokkelen, J., "Telnet Terminal-Type Option", FTP Software, Inc., February 1989. RFC 1092: Rekhter, J, "EGP and Policy Based Routing in the New NSFNET Backbone", T. J. Watson Research Center, February 1989. RFC 1093: Braun, H.

TIS is no longer advertising their net 10 address. USC and ISI are both making similar changes. Most problems with Datatel 3552 CSU/DSU units are fixed with 1.2 firmware in the units. Two problems are still outstanding. The T1 line for JPL is scheduled to be installed early March. Walt Prue will represent Los Nettos at the FARNet meeting held at Stanford March 1, and 2. Plans and orders for Phase 2 of Los Nettos installations are progressing. Walter Prue (Prue@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT The packet video host (PVP) was extended to enable interfacing with the WIDCOM video codec. Eve Schooler, Steve Casner, Dave Walden (schooler@ISI.EDU, casner@ISI.EDU, djwalden@ISI.EDU) NSFNET PROJECT Considerable effort this month was devoted to submitting a renewal proposal to NSF. Annette DeSchon and Bob Braden attended a meeting of the Autonomous Networks Task Force, and Bob Braden attended a meeting of the Open Routing Working Group, both held at ISI. Westine [Page 10]  Internet Monthly Report February 1989 Annette DeSchon started work on some additions to BFTP to support FTP Restart. With Jon Postel, we are looking into a possible new definition of the FTP Restart function that was proposed by Rick Adams. Bob Braden worked on updating the Host Requirements RFC with the changes agreed to at the Austin meeting, plus hundreds of changes proposd by Mike Karels and Charlie Lynn. This work is still in progress. Bob Braden and Annette DeSchon (Braden@ISI.EDU, DeSchon@ISI.EDU) FAST PROJECT ON REMOTE ACCESS OF GRAPHICS DATABASES Alan continued working on making the X version 11R2 server work under Sun Overview (we are currently installing X11R3). Alan is currently working on defining a Remote Execution protocol. Alan Katz (Katz@ISI.EDU) MIT-LCS ------- Dave Clark, Karen Sollins, and Lixia Zhang attended Autonomous Networks Task Force meeting held on February 14-15; Dave and Karen attended joint ANTF and Privacy Task Force meeting on February 16; Lixia attended Open Routing Working Group meeting on February 16- 17, all held at USC-ISI. The Gateway Testbed project is moving steadily towards its goal of deploying a national network for experimentation with gateway algorithms and new networking concepts. Software to support the gateway platforms is being readied. A decision on the bandwidth of the Testbed links will pave the way for finalizing the budget and subsequent deployment of equipment.

Westine [Page 11]  Internet Monthly Report February 1989 NEARNET ------- Installation of the hub of the New England Academic and Research Network (NEARNet) was completed in February, connecting Boston University, Harvard University, and the Massachusetts Institute of Technology. NEARNet will eventually serve many New England organizations engaged in research, development, and education. The initial hub was a cooperative effort among the three participants. Seed funding to expand the hub to a Phase 1 network of nine sites in Greater Boston (including the three above) has been provided by DARPA, with additional funding from the sites themselves. We expect all nine to be operational in April, with others added soon thereafter. Seven of the Phase 1 sites will be linked at 10Mb rates using microwave technology. The network will be redundant with automatic load sharing handled by Cisco routers which are capable of routing packets at Ethernet speeds. Outlying areas will be served by microwave connections, T1 land lines, and 56Kb land lines. NEARNet will be connected to the Defense Research Internet, the ARPANET, and NSFNET. Boston U., Harvard, and MIT are acting as the Steering Committee for NEARNet initially; they have contracted with BBN to be the facility operator. An expanded Planning Group, with representatives from several New England states, will hold its first meeting in April.

Westine [Page 12]  Internet Monthly Report February 1989 SRI --- SRI hosted the User Interface Taskforce meeting chaired by Keith Lantz. As part of the meeting, the teleconferencing facility was used to demonstrate the latest version of multimedia conferencing software from BBN. We used this opportunity to experiment with large screen displays for the computer screen information to facilitate larger groups (about fifteen) in one room. Although special lighting was used to accomodate both the video camera and the large screen projector, improvements are still possible. Earl Craighill (EJC@TSCA.ISTC.SRI.COM) UCL --- We held some informal discussions on mutual aid for Transatlantic links between European and US Research Networks. We have just upgraded the nodes on our FDDI network and expect it to run as a service from Easter. Both of these projects have unearthed some problems with DECNET addressing as connectivity grows. We have just joined another RACE (Research into Advanced Communications for Europe) project called CAR (Communications for the Automotive industry under RACE). They have some interesting (stressful) applications for Internetworking, especially in the area of Distributed CAD/CAM for car design. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Our grads continue hacking theses and various odd jobs. Mike Minnich is working on feedback-control models for networks of hosts and gateways. Paul Schragger brought up the Profile system for an experimental white-pages server and NYSERNET SGMP for watching our gateway rascals. Jeff Simpson attended a meeting of the Autonomous Networks Task Force and is now sloshing in formal grammars for expressing routing policy. Dan Grim and Chuck Cranor hexed an ancient VAX witch and exorcized the last traces of our old class-C network numbers. Westine [Page 13]  Internet Monthly Report February 1989 2. Mike Davis completed a particularly messy job of cataloging and archiving precious and prodigous monitoring data collected during the two-year bumpy life of the old NSFNET Fuzzbone network. This includes hourly and weekly summaries of packet counts by interface, as well as error messages and various categories of dropped packets. Careful analysis showed that the mean hop count across the network was somewhat larger than expected (about 1.8 hops) for the particular topology used, which suggests performance could have been considerably improved by simply rehoming some of the links. 3. Documentation for the new Network Time Protocol (NTP) Version 2 was completed and stashed on louie.udel.edu for public display. Two PostScript documents are now available: pub/ntp/ntpx.ps, which describes the architecture, models and algorithms, and pub/ntp.ps, which is the specification itself. The new version, which is compatible with previous versions, includes an authentication feature using DES crypto-checksums, as well as improved clock- selection and local-clock synchronization algorithms using an adaptive-parameter phase- lock loop. Pending review of the authentication feature by the Privacy Task Force, the specification, now a Draft Internet Standard (DIS), will be proposed for promotion to Internet Standard (IS). 4. A good deal of activity occurred this month testing the new NTP Version 2 beta implementations for Fuzzball and Unix systems. Various bugs were found and corrected in the specification and implementations. A software simulator was constructed to explore the synchronization behavior over intervals up to several days. Marion Hakanson, Doug Kingston and Jerry Aguirre were particularly helpful and patient in finding subtle interactions with the Unix kernel that became evident only after days of observation. The new Unix daemon ntpd should be ready for public distribution early next month. 5. A high-stability, temperature-compensated crystal oscillator was installed on the Backroom Fuzzball to test the ability of the new NTP local-clock synchronization algorithm to maintain a long-term frequency stability in the order of a millisecond per day (about 10**-8) relative to NIST standards. The results show that, while stabilities in the order of 10**-7 can be achieved using presently available radio clocks and the Fuzzball implementation, further improvements appear to be limited due to the tracking loops in the radio clocks themselves. However, further improvements may be possible as inexpensive LORAN-C and GPS radiopositioning receivers become available. Ideas for incorporating precise timekeeping Westine [Page 14]  Internet Monthly Report February 1989 information as opportunities develop during the development of these systems are being discussed informally with the U.S. Coast Guard. Dave Mills (Mills@UDEL.EDU) Westine [Page 15]  Internet Monthly Report February 1989 NSF NETWORKING -------------- NSF NETWORKING UCAR/BOLT BERANEK AND NEWMAN INC., NNSC Craig Partridge attended the IAB Workshop on White Papers in Washington, D.C. by Karen Roubicek (roubicek@nnsc.nsf.net) NSFNET BACKBONE (MERIT) New Topology Merit and its partners, MCI and IBM announce a major redesign project to improve connectivity and move NSFNET toward the higher speeds required in the future. The new topology is scheduled to begin implementation during second quarter 1989. By increasing the number of T1 circuits in the backbone, connectivity to spur sites will be improved and network capacity as a whole will be increased with each node to have multiple T1 circuits. Primary goals of the new topology are to maximize network robustness and minimize bit traversal delay. A detailed implementation schedule is nearing completion and will be finalized in cooperation with the NSFNET regional networks. Questions should be sent to: NSFNET-info@Merit.edu NSFNET BACKBONE As of February 28, 1989, the NSFNET has completed eight months of production. Traffic and network connections have continued to increase during this period. The number of "allowed" networks began at 173 primary and 30 secondary on 7/1/88 and, as of 2/28/89, stands at 410 primary, 177 secondary, and 28 tertiary with new networks coming on line almost every day.

Despite the usual drop in traffic on weekends the upward trend was steady through the month, peaking on the 23rd and 24th. NNStat February marked the beginning of the use of more sophisticated methods for gathering statistics within the NSFNET backbone. These data, which are being compiled continuously at all 13 backbone nodes, include packet counts, protocol frequencies, packet size distributions, switching rates, and source/destination network matrices. Information gathered will aid the NSFNET partners in the analysis of network usage and will provide needed input for the planning of network configuration and expansion. by Patricia G.

Westine [Page 18]  Internet Monthly Report February 1989 JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK Monthly Status Overview: Overall, the JvNCNet network has performed very well for the month of February. The amount of traffic went up significantly and steadily as seen below, the reachability to the JvNCnet sites went down mostly due to a scheduled power outage at JvNC as can be seen below. The overall up-time for the network this month was 95.88%. The "estimated" amount of traffic in and out of the JvNCnet system for this month was 732,288,159 packets. This traffic is a significant increase from last month's (657,982,496 packets). The traffic coming from the NSFNet was approximately 28.80% of the total, the traffic coming from the ARPANET amounted to approximately 9.25 %, the traffic from NORDUnet was 1.99%, leaving 60.96% of traffic among JvNCnet Regional sites. Of all the JvNCnet Regional sites, MIT contributed with slightly more traffic than Rutgers. Rutgers has been the single site on the network to contribute with more traffic for the last few months. The router for NORDUnet arrived ("bart") and was installed, therefore the connection of NORDUnet was moved from Trillian to Bart. A scheduled power outage affected JvNC and all incoming telecomunications services. This power outage was necessary to put one of the Motor Generators (MG) in place. This disruption will help the network equipment in the future by isolating it from the electric power "glitches" produced outside the Center. A problem which affected six North East institutions was finally confirmed and resolved. The problem was severe congestion on the Cisco routers connecting: Boston University, University of Massachusets, Dartmouth, Northeastern, Yale and Wesleyan. The problem was actually due to a "bug" on some EPROMs that were being used on those routers, in addition of higher load on the network. A technician was dispatched from JvNC to replace the EPROMs. The replacement took four days to be accomplished. The results have been remarkably good. Congestion drops have been reduced significantly on those gateways. All the Cisco routers have been upgraded with version Westine [Page 19]  Internet Monthly Report February 1989 7.0(399). This software upgrade couldn't be completed until the EPROMs in some routers were changed. After the EPROMs were replaced, the routers had no problem to boot their new image. The circuit and equipment for the connection to JANET (Joint Academic Network) in the UK to the NSFnet at JvNC has been ordered. The router arrived and has been tested and configured. The circuit will be installed (as per Contel) before the end of March. Siemens Research is now operational and will be incorporated to the traffic report next month. The installation of the first group of the JvNCnet Phase II is in progress. We expect by the second week of March to see the Newark Backbone Node, as well as the following end nodes will become operational: Rutgers, NJIT, UMDNJ, Stevens Institute. A few weeks later the Phase I/Rutgers circuit will be disconnected. The next RCI/JVNC Implementation team will meet on the seventh of March at JvNC. The JvNC Network Operations Center (JvNCNet NOC) provides support to the JvNCNet network as well as the internal network of the JvNC. The NOC is staffed from 9am to 5pm Monday through Friday. The computer operators monitor and perform minor troubleshooting tasks between 5 p.m. and 9 a.m. and are the backup for the Network Operations Center. Network Staff are on call after hours and during weekends and holidays. The JvNC Network Information Services Center is now staffed, and provides support from 9am to 5pm Mondays to Fridays.

MRNET One new member, Honeywell, attached to MRNet during February. ARPAnet connectivity was often poor, and Internet access in Westine [Page 20]  Internet Monthly Report February 1989 general seemed to suffer as a result. On March 1, the U of Minn's ARPAnet line was officially cut (though still functioning). The effect on Internet access is not yet clear, but it will simplify network operations. In late February, CICnet lit up, promising substantially faster access to other NSFnet sites for U of Minn. and MSC users; other MRNet members are not yet using CICnet. We ran NNStat for part of this month with some interesting results: - our largest users are UofM/MSC and CDC; - most-used TCP/UDP services are NNTP, rlogin, telnet, SMTP, domain and FTP in about that order, with NNTP about 3 times FTP; - inter-member traffic is 50-65% of all non-routing traffic i.e. we're not all just talking across the Internet. by Stuart Levy (slevy@msc.umn.edu), and Tim Salo (tsj@ucmsc.umn.edu) NATIONAL CENTER FOR ATMOSPHERIC RESEARCH AND UNIVERSITY SATELLITE NETWORK PROJECT The National Institute of Standards and Technology (NIST), Boulder Division (net 132.163) is now gatewayed to the NSS via the NCAR node. The Boulder NIST was formerly part of the Gaithersburg NIST (129.6) and still maintains a direct link to that net. USAN statistics for February show the following daily average traffic received by the USAN hub from the various sites. Supervisory data between the hub and each site account for over 0.1 Mbytes. Naval Research Lab 4.53 Mbytes University of Maryland 0.18 Mbytes University of Miami 10.87 Mbytes University of Wisconsin 12.25 Mbytes Woods Hole 9.08 Mbytes Oregon State University 2.95 Mbytes Institute for Naval Res. 4.16 Mbytes by Don Morris (morris@windom.ucar.edu) Westine [Page 21]  Internet Monthly Report February 1989 NORTHWESTNET We are presently in the process of a major effort to understand and re-engineer the network. Some sites experience unacceptably long packet latencies due to multiple hops on 19.2Kb voice grade circuits. Although our network manager (Boeing Computer Services) has been unable to provide detailed outage or traffic data, we don't seem to have bandwidth problems -- despite a mix of 56Kb and 19.2Kb circuits (no T1 here in the boondocks!). A major emerging issue is the degree of path redundancy desired/affordable. Also, we have approved in principal a new class of network memberships targetted at small for-profit research organizations. Apart from one significant line failure in late February, the network has operated reliabily. by JQ Johnson (jqj@hogg.cc.uoregon.edu) NYSERNET No report received. OARNET No report received. PITTSBURGH SUPERCOMPUTING CENTER PSC has installed and is now testing a new gateway which will be the primary path between the NSFnet and the ARPAnet. The current gateways at Cornell and UIUC are scheduled to be disconnected from the ARPAnet by the end of March. by Matt Mathis (mathis@fornax.ece.cmu.edu) SAN DIEGO SUPERCOMPUTER CENTER On Friday, 13 Jan., SDSC began peering with the Buttergates. We are working with SRI/TGV to implement the FTP command PASV in Multinet. This will support BFTP, among other things. NFS is now in production use under Multinet on our VAX Cluster. Westine [Page 22]  Internet Monthly Report February 1989 During Feb. a T1 link to Naval Ocean Systems Center, Pt. Loma [San Diego], Calif. became operational. This link uses a pair of Bridge IB/3's together with a dual-Ethernet VAX 11/750 at NOSC to tie the two locations together while separating the two nets. The CERFnet test network has been expanded with a 56k link to UCLA provided by the University's Office of the President. SDSC's old NSFnet I Fuzzball is providing Stratum 1 NTP services. The University of Nevada has selected SDSC as its connection point into NSFnet for their statewide system. This system will make use of an upgrade to an existing microwave system to carry a data channel throught the state (as well as between the Reno and Las Vegas campuses). The 56k line to San Diego is expected to be operational about 15 March. Also, during the month we expect start carrying IP traffic over the 56k DECnet link to SAIC. This is a temporary measure to provide a continuation of Internet access to SAIC after the 17 March removal of their ARPAnet host connection. It will be replaced by a CERFnet link in early May. Finally, in March we expect to convert our 56K SDSCnet link to the Research Institutes of Scripps Clinic to a p4200 link carrying both TCP/IP & DECnet. by Paul Love (loveep@sds.sdsc.edu) SESQUINET No report received. 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 57 sites online and 71 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) Westine [Page 23]  Internet Monthly Report February 1989 WESTNET 1. T-1 Line Between University of Colorado at Boulder and NCAR: For large packets, we were experiencing high error rates on the T-1 line between UCB and NCAR. We had originally thought there was a problem with the Dowty Information System T-1 CSU's, as we had reported last month. This was incorrect; the problem was eventually tracked down to problems in the US West span between UCB and the Table Mesa Office. US West has provided a different span, and the performance is now satisfactory. 2. New Networks: The following networks were added to Westnet-East USGS 192.41.213 U.S. Geological Survey (Denver) VLA 192.43.204 Very Large Array Telescope (NM) AFWL 129.238 Air Force Weapons Lab (NM) 3. Collection of Statistics with SNMP Carol ward has this month begun using SNMP to collect statistics in "production mode." 4. New 56 Kbps Circuit from University of Wyoming to Colorado State University The link was upgraded from a voice grade circuit using compression modems (yielding 19.2 Kbps) to a 56 Kbps subchannel on a microwave circuit. The microwave circuit was a joint venture between UW and CSU for passing video traffic. by Pat Burns (pburns@super.org), and Carol Ward (cward@spot.colorado.edu)
