[IMR] IMR88-08.TXT August 1988 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). BOLT BERANEK AND NEWMAN INC. ---------------------------- WIDEBAND NETWORK The Wideband Net and associated Arpanet IST lines suffered a degradation in service during the past month as frequent resets plagued the network. Work is in progress to correct this problem. Software to support IP multicasting over the Wideband Net was distributed in August. The software extends the HAP group addressing scheme to allow extra-HAP (32 bit) destination addresses to be specified in messages sent to the Wideband Net. Network hosts may join such an address and will receive copies of all messages sent to the address. Westine [Page 1]  Internet Monthly Report August 1988 SATNET The operation of the SATNET was very stable during August. There were no unscheduled outages. The antenna at the Tanum Earth Station was repointed to a different satellite on August 17th, thus removing it from the SATNET. Jon Crowcroft (University College London), Claudio Topolcic (BBN), and Karen Seo (BBN) attended the ACM SIGCOMM 88 Symposium held at Stanford University, Stanford, California. Karen presented a paper, "Distributed Testing and Measurement across the Atlantic Packet Satellite Network (SATNET)", which summarized the results of the SATNET Measurement Taskforce. The taskforce plans to write several additional reports that will contain more detailed descriptions of this work. INTERNET R&D We shipped hardware and software to RSRE and NTA to support the installation of a line between the gateways at NTA and RSRE. This will get NTA back on the air after their Satnet earth station was pointed at the wrong satellite. Bob Hinden (Hinden@BBN.COM) ISI --- Internet Concepts Project Work on a network simulator sufficient to test some congestion control ideas has been pretty much completed. It is intended for testing several differing approaches for IP congestion control that depend upon the host IP module maintaining separate congestion control queues indexed by destination network. For that purpose it is assumed that gateways generate Source Quench messages when their queues overflow. That information, when it returns to the source host, is used to clock out IP packets to the affected destination network much the way cars are clocked onto freeways when a freeway is congested. The simulator will allow testing these approaches under differing topologies, loads and with differing link characteristics. Greg Finn Joyce Reynolds attended the InterNICs meeting at Stanford University, Stanford, CA, August 16th. Paul Mockapetris presented Westine [Page 2]  Internet Monthly Report August 1988 his paper "Development of the Domain Name System", at the ACM SIGCOMM 1988 Conference, at Stanford University, 16-19 August.

Ann Westine (Westine.ISI.EDU) Los Nettos A user-supported regional network has been formed in the Los Angeles area to provide connectivity between sites such as individual campuses and research centers in the area and to provide connectivity to long haul networks for all the campuses and centers. This regional network is called "Los Nettos". Los Nettos will connect to several long haul and national networks, such as the ARPANET, the NSFNET, the WBNET, and the DRI. Los Nettos is operated by the member organizations, not by DARPA, or NSF, or DOE, etc. Westine [Page 3]  Internet Monthly Report August 1988 Los Nettos is being developed in phases. Each phase will add a group of sites together. This phased approach allows a reasonable topology for Los Nettos to evolve. The technical committee assists in the development of the system design and the topology. One important feature of Los Nettos is that it is "high speed", all connections and links are (and will be) at least T1 (1.5 mb/s) rate. Five organizations have already joined Los Nettos and the first phase of implementation is under way. The sites in phase 1 are: Site Representative ------------------------------ -------------- Caltech Computer Science Chuck Seitz ISI Jon Postel TIS Steve Crocker UCLA Computer Science Len Kleinrock USC Academic Computing (UCS) Dick Kaplan Sites wishing to participate in phase 2 should contact Walt Prue (PRUE@ISI.EDU) before 30-Sep-88. Walter Prue attended the FARNET meeting. Jon Postel and Walter Prue attended the CAL Internet meeting in Irvine, August 23, 1988. Walter Prue (Prue@ISI.EDU) Multimedia Conferencing Project The voice echo canceller implemented for the packet voice system is now operational and ready for testing over the Wideband Net. It is implemented on an NEC 77P20 digital signal processing chip and is mounted on a Switched Telephone Network Interface (STNI) card. The STNI, developed by ISI and BBN, sends and receives TouchTones and digitizes voice signals to interface between a telephone line and the packet voice terminal program. Echo occurs when the far-end signal is reflected from the 2-to-4 wire hybrid circuit required in each STNI to couple voice signals from the packet system into the two-wire telephone network. The echo canceller uses the well known transverse filter technique to estimate the echo and subtracts this estimate from the near-end signal. We have fine-tuned the echo canceller algorithm parameters for the local ISI environment and will proceed with testing over the satellite. Improvements were made in the software implementations of MMCC (for conference control) and PVP (the video packet host in the Butterfly). The I/O interfaces in PVP, which communicate with the video codec and the Voice Funnel gateway, were modified to use a newer version of BBN's synchronous I/O library. This is in Westine [Page 4]  Internet Monthly Report August 1988 preparation for interfacing with BBN's upcoming Butterfly ST Gateway. A first draft of a document describing the multimedia conferencing system was composed this month. Its purpose is to give an overview of the system and to define the requirements for installation of a new MMC site. It outlines the major components of the teleconferencing system, provides some cost estimates, and states current impressions as well as future directions. This document was prepared in Diamond and includes several pretty diagrams. After review it will be available for distribution. Dave Walden, Eve Schooler, Brian Hung, Steve Casner (djwalden@ISI.EDU, schooler@ISI.EDU, hung@ISI.EDU, casner@ISI.EDU) NSFNET Project Annette DeSchon continued work on the BFTP programs, adding some new features and making some minor repairs. The BFTP programs include an internet server, a TTY-style interface for BSD machines, and a "bftptool", which runs on a Sun workstation. Sources will be available via anonymous FTP in the next few days. A BFTP server is currently running on "hobgoblin.isi.edu", port 152, and can be accessed via the "telnet" protocol. Bob Braden hosted the IETF-Hosts meeting at ISI August 4, and chaired a meeting of the End-to-End Task Force at Stanford on August 16th. Bob also presented his paper, "A Pseudo-Machine for Packet Monitoring and Statistics" at the ACM SIGCOMM'88, Conference at Stanford University, Bob Braden and Annette DeSchon (Braden@ISI.EDU, DeSchon@ISI.EDU) Supercomputer and Workstation Communication Project Alan Katz continued to debug and test the remote split editor and has been working on which runs under GNU Emacs. Alan also began work on a paper on Supercomputer-Workstation interaction. Alan Katz (Katz@ISI.EDU) MIT-LCS ------- No report received.

UCL --- Jon Crowcroft attended the End to End Task Force meeting, and SIGCOMM 88 symposium at Stanford. A great deal of effort on the Directory Service and Mail (X.500 and X.400) applications for ISODE was carried out, and a number of steps forward made. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Jeff Simpson continues to work on policy issues in network routing. This past month he toiled with the OPSNET network simulator and now has it running on a Sun workstation. He will be using the simulator as a testbed for policy routing strategies. Additionaly, he is collecting and organizing information on network policy in order to write a summary of policy systems now popular in the Internet. 2. Paul Schragger is reviewing the literature on catastrophe theory and its application to network performance and behavior analysis. The goal of this work is to evolve control schemes that globally optimizes network utlization in the face of congestion and misengineered implementations. Also, Paul continues to work on the MIT network simlator, in particular to construct a Poisson packet source. Both the delay between packets and the packets lengths can be fixed or exponentially distributed. He is using this to explore the standard queing Westine [Page 6]  Internet Monthly Report August 1988 models and their behavior compared to a simple catastrophe model. 3. All of the original six NSFNET Backbone fuzzballs are back on the air, two (NCAR and UIUC) configured as primary time servers and the remaining four as secondary time servers. Precision Standard Time, Inc., kindly furnished a Model 1020 WWV-synchronized clock for evaluation. A driver for it instantly materialized and it is now ticking happily on one of our U Delaware fuzzballs. Also, the fuzzball timekeeping code was extensively revised to improve its resistance to falseticking radios, some of which are becoming increasingly cranky as Solar Cycle 22 ramps up to the max. 4. Continued low-level problems with U Delaware access to the Internet via SURANET have not been resolved. The problems result in occasional loss of packets, sometimes accompanied by ICMP error messages, under conditions of very low traffic and general tranquillity. The problems are readily noticeable in the logs for the various time servers, both here and elsewhere in the internet, and are almost certainly not new. As SURANET is now claiming reachability of about 200 networks, we suspect its switching fabric might be RIPping in some places. 5. Dave Mills presented a paper and chaired a session at the SIGCOMM 88 Symposium IAB meeting in Palo Alto, presented a briefing on the Dissimilar Gateway Protocol at DCEC in Reston and attended a NAS meeting on Telecommunications Network Survivability in Washington. Work continues with Paul Schragger on developing a strawman proposal for a high-speed reservation-switched network model suitable for early evaluation. One of the weekend projects was a close examination of ancient and modern calender systems and their synchronization principles for the lunar, solar and ritual year. Well, this rather got out of hand and may result in a new timestamp format for Maya Long-Count dating of Internet events. Dave Mills (Mills@UDEL.EDU) Westine [Page 7]  Internet Monthly Report August 1988 NSF NETWORKING -------------- UCAR/BOLT BERANEK AND NEWMAN INC., NNSC Craig Partridge attended the End-2-End Task Force meeting at Stanford and spoke on a panel at the SIGCOMM conference. Karen Roubicek attended the FARNET meeting and will participate in the FARNET committee established to improve network information and operations services within NSFNET. An NNSC/CSNET representative attended the Internics working group meeting and discussed X.500 Directory Services. by Karen Roubicek (roubicek@nnsc.nsf.net) NSFNET BACKBONE (MERIT) August was the second month of production mode for the NSFNET backbone. Activity on the NSFNET backbone is running smoothly. Facilities for the formal collection of data are beginning to be implemented. New campus nets are still being added. As of August 31, 241 NSFNET known campus nets were in our routing tables and 247 ARPAnet networks were also reachable through the NSFNET backbone. Thus, over one half of the networks in the Internet are directly reachable via the NSFNET backbone. IBM and the Merit/NSFNET Internet Engineering group are experimenting with slow-scan motion packet video. Video images are now being transmitted between IBM's research facility in Yorktown and Ann Arbor. A demonstration has been given to Steve Wolff at the NSF through the NSFNET backbone. In its present state, packet video would use a significant amount of bandwidth. Currently, video packets are not compressed. The future promises a number of changes and enhancements. Full-duplex is a logical step to explore, so that video images can be sent and received at the same time. Development of multi-cast images would allow more than one location at a time to receive the same video image. The NOC is now operating on a twenty-four hour schedule. To combat "air traffic controller syndrome" an innovative, flexible scheduling system is being implemented. by Laura Kelleher (lkelleher@merit.edu) Westine [Page 8]  Internet Monthly Report August 1988 NSFNET BACKBONE SITES & MID-LEVEL NETWORK SITES BARRNET No report received. CERFNET No report received. CORNELL UNIVERSITY THEORY CENTER Development continues on the gated software. EGP3 is being revised and will be implemented in the gated code. International connectivity has become an important project this fall. The Ontario regional network will be connecting into NSFNet via Cornell early this fall. A connection to CNUSC (Centre National Universitaire Sud de Calcul) in Montpellier, France should be implemented by mid-fall. The issue of user support in a national, multi-networked environment has always been a concern for Cornell and is now gaining attention on a national level. FARNET has created a committee to discuss this issue. Martyne Hallgren will be participating in it. by Martyne M. Hallgren (martyne@tcgould.tn.cornell.edu) UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET A problem with our Arpanet gateway machine (uxc.cso.uiuc.edu) that involved running out of network mbufs after two to four days of operation was resolved. The solution was to replace the 3Com Ethernet board with a second Interlan 1010A card. Our WWVB clock (truechimer.cso.uiuc.edu) is still ticking in tune with NBS despite the steel framework of the building addition going up around the antenna. A second Class B address was approved by Hostmaster (uiuc-ncsa 130.126) and will be used to bring some regularity to the hodgepod of regional connections that terminate at UIUC. by Paul Pomes (paul@uxc.cso.uiuc.edu) NCSAnet Illinois Institute of Technology is not connected to NCSAnet via the Chicago Area Hub at 56Kbps. The current NCSAnet Westine [Page 9]  Internet Monthly Report August 1988 topology is a two hub topology with T1 interconnecting the hubs at NCSA and UI-C: NCSA Hub: Indiana University (T1) University of Wisconsin-Milwaukee/Parkside (56Kbps) Fermi National Accellerator Laboratory (14.4Kbps) UI-C Hub: University of Chicago (T1) Northwestern University (T1) University of Notre Dame (56Kbps) Argonne National Laboratory (56Kbps) Illinois Institute of Technology (56Kbps) The NSFnet and ARPANET connections are via NCSA/UIUC. Work is currently under way to provide email only connectivity to AMOCO.COM (Tulsa and Naperville labs) and Motorola.COM (Schaumburg) via existing NCSAnet private connections to these sites. Charlie Catlett (catlett@ncsa.uiuc.edu) JVNCNET This report is designed to inform the JVNC Consortium and JVNCnet network members as well as the Internet community of monthly status of the JVNCnet network. The data used on this report is collected using a number of techniques developed at JVNC. Monthly Status Overview: The overall uptime for the gateways this month was 84.85% (worst case, this number considers that all gateways are unreachable when JVNCA is down). The measured uptime when JVNCA was available (94.70% of the time) was for an average on all the gateways 80.35% available. The "estimated" amount of traffic in and out of the JVNCNet system for this month was 340,000,000 packets. This is a very high number (specially considering that 15 of the 25 gateways are VAXs, and their performance was highly degraded). Of this traffic, approximately 30% was coming from the NSFNet, 10% from the ARPANET, and 60% from JVNCNet sites. The NSFNet network (as seen from JVNC) is performing very well. Interactions between the MERIT staff and the JVNC staff is a demonstration of the high degree of cooperation that exists between the two organizations. The result is a smooth operation, which we expect will develop even further. Westine [Page 10]  Internet Monthly Report August 1988 Plans are moving ahead for the connection of the JANET (Joint Academic Network) in the UK to the NSFNet at JVNC and the connection of the NORDUnet (Nordic Countries Network) to the NSFNet at JVNC. Both connections will be on 56kbps circuits (over satellite), the connection to JANET will be X.25 protocols, while the connection to NORDUnet will be a TCP/IP connection. In either case, CISCO routers will be utilized. Both routers will be connected to the JVNC External network (ethernet) joining the NSS, and two JVNC (core) CISCO routers (which are both connected to PSN16). 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 by the network staff from 9 a.m. to 5 p.m. Mon-Fri, and is on call between 5 p.m. and 9 a.m. and during weekends and holidays. The computer operators monitor and perform minor troubleshooting tasks between 5 p.m. and 9 a.m. and provide for backup network operations center.

NATIONAL CENTER FOR ATMOSPHERIC RESEARCH AND UNIVERSITY SATELLITE NETWORK PROJECT One noticible effect of the cutover to the new NSFNET has been the sudden increase in file traffic for in the 5Mbyte-10Mbyte range and even one of 21Mbytes. These files are generated as output from the NCAR CRAY computers from jobs submitted by the the NCAR developed IRJE (Internet Remote Job Entry) job submittal system. Files this Westine [Page 12]  Internet Monthly Report August 1988 large are automatically staged to be delivered back to the user during the middle of the night.

PITTSBURGH SUPERCOMPUTING CENTER The network has been getting much more reliable as we correct residual problems left from the complete reorganization over the summer. There were only 4 transient and no sustained outages in external connectivity during August which were caused by PSC resources. The SURAnet T1 link is now isolated by a new gated agent, psc- gw2.psc.edu. PSC and SURA are providing full secondary NSFnet access for each other through this link. PSC is also providing secondary NSF access for PREPnet sites who are using JVNC as their primary. The affected networks are Penn State, Univ of Penn, Drexel, Temple and Lehigh. The DEC VMS 8810 front ends to the Cray are now running SRI Multinet TCP/IP. This has solved many problems with network access to the Cray, but there is still an intermittent serious problem with the DEC DELUAs. This affects DECNET and all of the TCP/IP implementations we have tested. Our next step is to upgrade VMS to version 4.7. There have been other internal problems only affecting access to the Cray, including a flaky ethernet interface in a Proteon P4200 and a power interruption to the Cray machine room. by Matt Mathis (mathis@faraday.ece.cmu.edu) SAN DIEGO SUPERCOMPUTER CENTER Our ARPAnet PSN has had its first offsite host line installed. The DSU is still pending. Our upgraded p4200 (new CPU and Ethernet interfaces) has arrived. It will be installed during the second week of Sept. Westine [Page 15]  Internet Monthly Report August 1988 The CERFnet evaluation cisco router has been installed on our Ethernet. Some minor difficulties have been experienced in configuring it. (See the CERFnet report for full details.) The VMS 5.0 version of SRI's MultiNet TCP/IP package is up and running on our VAX 6210 (topgun.sdsc.edu). We have ported an X11 client to our Cray and CTSS. by Paul Love (loveep@sds.sdsc.edu) SESQUINET The complete initially proposed SesquiNet configuration has been operational for a year now. The following campus networks are being served, and are advertised via EGP to NSFnet and (currently via UIUC) to the Arpanet core: Baylor College of Medicine 128.249 BCM-Technologies 192.31.88 Houston Area Research Center 192.31.87 Prairie View A&M University 129.208 Rice University 128.42 Texas A&M University 128.194 Texas Southern University 192.31.101 and the University of Houston 129.7 The new NSFnet backbone node at Rice University became operational during the last week of June, and has proved quite reliable. FTPs of 96kb/s across the new NSFnet are typical. In cooperation with the University of Texas, we are building a triangular network including UT-Austin and the Sesquinet sites at Rice and Texas A&M. This triangle will connect Sesquinet (and NSFnet) to THEnet, a multi-campus network centered at the University of Texas. We hope this will be the first of several such cooperative projects. by Guy Almes (almes@rice.edu) SURANET The following SURAnet sites are presently on-line: University of Alabama at Birmingham Alabama Supercomputer Network University of Alabama at Tuscaloosa Catholic University of America Westine [Page 16]  Internet Monthly Report August 1988 Clemson University Continuous Electron Beam Accelerator Facility University of Delaware Department of Energy/Oak Ridge Operations Office University of Florida Florida State University Fox Chase Cancer Center Emory University Gallaudet University George Mason University Georgetown University George Washington University Georgia Institute of Technology University of Georgia Johns Hopkins University University of Kentucky Louisiana State University University of Maryland Mississippi State University NASA/Goddard NASA/Langley National Bureau Of Standards National Cancer Institute/Frederick Cancer Research Center National Institute of Environmental Health Sciences National Institutes of Health National Radio Astronomy Observatory National Science Foundation Naval Research Laboratory Oak Ridge National Laboratory Old Dominion University Supercomputer Research Center (IDA) University of Tennessee Triangle Universities Computation Center Duke University North Carolina State University University of North Carolina Vanderbilt University Virginia Commonwealth University US Geological Survey University of Virginia Virginia Polytechnic Institute University of West Virginia College of William & Mary Westine [Page 17]  Internet Monthly Report August 1988 SURAnet Networks that are being advertised to the NSFnet: 128.4 DCN 128.8 University of Maryland 128.60 Naval Research Laboratory 128.61 Georgia Tech 128.82 Old Dominion University 128.109 Triangle Universities 128.140 Emory 128.143 University of Virginia 128.150 National Science Foundation 128.163 University of Kentucky 128.164 George Washington University 128.167 Southeastern Univ.
