[IMR] IMR88-09.TXT SEPTEMBER 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. ---------------------------- No report received. Bob Hinden (Hinden@BBN.COM) ISI --- Internet Concepts Project Greg Finn is running simulations to determine the effectiveness of some end-to-end congestion control schemes that are implemented at the IP protocol level. Greg is also writing a short report of the results. Westine [Page 1] Internet Monthly Report September 1988 Greg Finn (Finn@ISI.EDU) Paul Mockapetris worked on the hosts requirements RFC, installed new domain software at the TOPS-20 root servers to correct some minor bugs and allow a larger database. Paul attended the Interop 88 Conference, September 27-30, at Santa Clara where he presented a two-day tutorial on the Domain Name System. Paul Mockapetris (pvm@ISI.EDU) Annette DeSchon made some additions to the Intermail mail forwarding system so that it would use a dial-out modem to exchange mail with two commercial mail systems, the IEEE Compmail system, and the NSFMAIL system. In addition some of the forwarding functions are being taken over by the new Commercial Mailer system that is being developed by the ISI Computer Center. Annette DeSchon (DedSschon@ISI.EDU) Jon Postel, Walter Prue, Joyce Reynolds and Ann Westine attended the INTEROP 88 Conference in Santa Clara. Jon Postel hosted the Board of Directors the Los Nettos meeting at ISI. Walter Prue attended the CISCO Systems Customer Training program, September 11-13. One RFC was published this month. RFC 1071: Braden, R., (ISI), D. Borman (Cray Research), C. Partridge, (BBN), "Computing the Internet Checksum", September, 1988. Ann Westine (Westine.ISI.EDU) Los Nettos As described last month, 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 greater Los Angeles area and from Santa Barbara to the San Diego area. It will provide connectivity to long haul networks for all the campuses and centers. All of the equipment, T1 facilities, and cables have been ordered for the first phase of Los Nettos. The five sites, ISI, UCLA, TIS, CalTech, and USC have T1 lines due in October. Some sites have a second line due early November. Cisco gateway routers have arrived. Westine [Page 2] Internet Monthly Report September 1988 A board-of-directors meeting was held September 16. Discussed were finances, management, appropriate use, back door use, and network usage billing. Los Nettos was represented by Walt Prue at the September 28, California Internet Federation meeting held at Interop 88. Discussed were federation goals, voting rules, and methods for Northern California to Southern California interconnection. The north-south interconnection looks promising. The next California Internet Federation meeting will be held at ISI December 9. Two sites have expressed interest in the next phase of Los Nettos. Any sites wishing to participate in phase 2 should contact Walt Prue soon. Walt Prue (Prue@ISI.EDU) Multimedia Conferencing Project This month Brian tested the packet voice echo canceler over the Wideband net with Vanessa Rudin and Lou Berger at BBN. In these tests algorithm constants were chosen for best performance. The cancellers are now in operation at ISI and BBN. A document describing the theory and implementation of the echo canceler is available. (Brian has completed his studies at USC and moved on to E-Systems, Inc. Inquiries on the echo canceller may be directed to Casner@ISI.EDU). PVP, the Butterfly-based packet video handler, was converted to be compatible with Chrysallis release 3.0 and the new Greenhills C compiler. The protocol between the multimedia conferencing control program (MMCC) and the Voice Terminal (VT) program has been augmented so that packets are now exchanged in both directions to open and close conference connections and to acknowledge the completion of conference set up. Demonstrations of multimedia conferencing were given to Yao-Sing Tao from Singapore's Information Technology Institute and to Dr. William Wulf and Dr. Charles Brownstein of the National Science Foundation. Eve Schooler attended the Computer-Supported Cooperative Work '88 Conference in Portland, Oregon. Steve Casner attended the 2nd Packet Video Workshop in Turin, Italy. Eve Schooler, Brian Hung, Steve Casner, Dave Walden, schooler@ISI.EDU, hung@ISI.EDU, casner@ISI.EDU, djwalden@ISI.EDU) Westine [Page 3] Internet Monthly Report September 1988 NSFNET Project Bob Braden presented a talk at the Interop '88 meeting on the Gateway Requirements and Host Requirements RFC's. One RFC was published. RFC-1071, "Computing the Internet Checksum" by Bob Braden, Dave Borman of Cray Research, and Craig Partridge of BBN which is an outgrowth of the efforts of the IETF Host Requirements Working Group. Annette DeSchon completed a BFTP software release and prepared an article on BFTP for the ConneXions newsletter. A compressed "tar" file is available for anonymous FTP on VENERA.ISI.EDU. Work continued on putting together the Host Requirements RFC. Two major critiques where received, extensively reviewed, and incorporated into the document. Substantive issues discussed by the Working Group during this month included: the effect of ICMP Destination Unreachable on TCP connections, legal names in Telnet Terminal Type options, the precise definition of the Nagle Algorithm, appropriate initial Type-of-Service values, and TCP listen concurrency. A new major draft (dated Sept 22) was reproduced for the Interop conference (thanks to the NIC and the NNSC for each reproducing 50 copies of this 150 page document!) A subset of the IETF Working Group on Host Requirements met at Interop '88 to consider a new proposal from Steve Deering for gateway discovery and dead gateway detection. Bob Braden and Annette DeSchon (Braden@ISI.EDU, DeSchon@ISI.EDU) MIT-LCS ------- Radia Perlman has happily finished her PhD dissertation (Title: "Network Layer Protocols with Byzantine Robustness", Supervisor: David D. Clark). She is now back to Digital Equipment Corporation. People interested in getting a copy of the thesis should contact her directly at "perlman%nac.dec@decwrl.dec.com". Lixia Zhang (Lixia@XX.LCS.MIT.EDU) MITRE Corporation ----------------- No report received. Westine [Page 4] Internet Monthly Report September 1988 NTA-RE and NDRE --------------- 1. Our SATNET connection was permanently taken down on August 17. 2. The long promised replacement, the 9.6 kb/s line between NTA- RD and RSRE finally became operational on September 28. NTA had promised to have the line installed by May/June, but could not live up to that for various reasons. And when the line was in place, the butterfly gateways at both ends were not prepared, among others due to delay in the upgrading of the RSRE-side. I would like to make use of this opportunity to thank all parties involved in the joint effort to reestablish our connectivity to the internet; John Laws of RSRE, Terry Brett of BTI, Mike Brescia of BBN, Mark Pullen of DARPA, Paul Ivar Myhren of NTA, and not to forget myself. If this line is a temporary solution or a permanent one remains to be seen. 3. NORSAR has for some time had an order for a 64 kb/s satellite link to CSS in Washington DC. The link is expected to be up late October, and will be terminated in Proteon gateways at both sides. Most probably the line capacity will be filled up with seismic information. It will be investigated if the line can be accessed by traffic from the other institutes at Kjeller. Academic traffic will definitely not be permitted over that line. 4. The academic community decided to go by a common Nordic solution, by establishing NORDUNET, with a 64 kb/s line from Stockholm to JVNC in the US. NORDUNET is a giant ethernet, spanning Trondheim, Stockholm, Helsinki and Copenhagen. Ethernet segments in the four cities are interconnected by means of VITALINK bridges, thus permitting TCP/IP, DECNET, ISO and X.25 traffic to flow between the national networks in the Nordic countries. NORDUNET will only contain gateways and a few servers or mail-bridges for EARN and HEPNET. The gateways connect to the various national academic networks, to NSF-net at JVNC and to COSINE somewhere in the Netherlands (X.25). The US-line is completely funded by the Nordic countries, and is expected to be up and operational in late October. 5. NDRE is currently considering its possible participation in ICB, evaluating the benefits it may have and weighing that against the utilization of its scarce resources. The evaluation was initiated by a letter from DARPA to the Westine [Page 5] Internet Monthly Report September 1988 director of NDRE, and will be prperly responded to in due cource. Tor Gjertsen (NDRE) and Paal Spilling (Paal@TOR.NTA.NO) SRI --- Zaw-Sing Zu attended Open Routing Working Group meeting held September 14 and 15 at BBNCC in Cambridge, MA. Zaw-Sing Su (zsu@tsca.istc.sri.com) UCL --- The UCL MAC Bridge implementation has been expanded to a four port (2 Ethernet, 2 2 Mbps serial) version, and now includes IEEE 802.1 Addendum B management protocols, using correct ASN encoding of management protocol data units (courtesy of Pepy/ISODE), over LLC1. A simulator has been completed for testing topologies, and measuring packet loss during Bridge reconfiguration, which incorporates that actual Bridge routing code. The Bridge also supports Telnet login, with passwords, for remote management from high level hosts. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Mike Minnich is experimenting with gateway congestion avoidance techniques. thus far has concentrated on the effectiveness of load estimators and end-node congestion indicators (source quench, packet drops, DEC bit). Preliminary trials with the DEC-bit scheme have shown that it possesses a relatively long time constant resulting in overestimation of the burst period and underutilization of the network. 2. Paul Schragger is modifying the MIT network simulator to support interactive experiments whose results can be analyzed using the S statistical package. There are two sets of experiments planned. One of these involves conservative M/M/1 queues and is designed to display a baseline manifold showing the queue behavior as a function of service time. The other set involves various preemption policies with end-end ARQ and Westine [Page 6] Internet Monthly Report September 1988 is designed to explore the control space for instances of classic cusp catastrophe behavior. 3. Jeff Simpson is finishing up his logical-list processor, which produces and validates policy-based routes. Both the lexical analyzer and parser are now defined and functional. A forthcoming paper will describe and summarize the existing routing policies and the concerns which are driving future routing algorithms/protocols. 4. As part of an undergrad project in VLSI, Chuck Cranor is working on a 3x3 digital crossbar switch for possible application to a high-speed reservation-based packet network. Digital Equipment has kindly donated a MicroVAX-I for possible use as an engine to drive such things. 5. The new timekeeping code has been deployed on all eighteen fuzzball time servers in the US and Europe. Louie Mamakos is now refitting the Unix 4.3bsd ntpd daemon to match. The NTP specification itself has been overhauled and an archival paper is on course. Two of the eight primary time servers have croaked and are suffering repair. One of them failed in such a way that its precision suddenly degraded to one 30-second monstertick every 30 seconds; however, the falseticker algorithms of its peers are chiming correctly with other peers to avoid timewarps. 6. Thanks to valuable input from Frank Kastenholz, the cause of the low-level problems reported with U Delaware access to the Internet has apparently been found. The problems are due to ARP cache timeouts in the Proteon gateways, which result in a packet being dropped about once every five minutes for each net. Besides causing low-level retransmissions at every level of traffic, this behavior destroys NTP peer associations at times when no other traffic is present and the polling rate drops below one per five minutes. We consider casual packet drops, especially under light-load conditions, as unclean, unneccessary and unmannered in any implementation, in spite of the well intentioned suggestions made in RFC-826. 7. Dave Mills presented a tutorial and chaired a session at the INTEROP 88 Symposium in Santa Clara. Work continues with Paul Schragger on developing a strawman proposal for a high-speed, reservation-switched network model suitable for early evaluation along with a strawman for the introduction of Maya calender-round timestamps for NTP. Dave Mills (Mills@UDEL.EDU) Westine [Page 7] Internet Monthly Report September 1988 NSF NETWORKING -------------- NSF NETWORKING UCAR/BOLT BERANEK AND NEWMAN INC., Staff of the NNSC met with Jim Sweeton of Merit at BBN to discuss the status of NSFNET information services and plan activities for the next few months. At the TCP/IP Interoperability Conference, Craig Partridge chaired a session on Internetwork Management and spoke at a session on Host and Gateway Requirements. by Karen Roubicek (roubicek@nnsc.nsf.net) NSFNET BACKBONE (MERIT) NSFNET Backbone With September over, the re-engineered backbone has been in full production for three months. Both traffic and network connections have increased dramatically in this period. The number of networks with primary connections to NSFNET through the mid-level networks has gone from 173 at the beginning of July to 292 by the end of September. Packet counts indicate traffic has more than doubled that carried by the old backbone. The figures below are packet counts on the new backbone for August and September 1988. (July statistics are not available.) As shown, September was over a third higher than August indicating rapid increases in usage of the new backbone. __________________________________________________ Packets in Packets out August 202,641,056 194,041,532 September 314,675,718 304,171,588 % increase 35.6% 36.2% __________________________________________________ The packet counts are taken at the token ring interface to the E-PSP in each Nodal Switching Subsystem (NSS) via SGMP. The counts are collected hourly and stored in a database on the Information Services host machine. As this database is Westine [Page 8] Internet Monthly Report September 1988 developed, it will be accessible to interested users. A software upgrade was made to all NSSs in mid-September. This included enhancements to priority-based traffic and filtering on the backbone. A number of Merit/NSFNET staff members participated in Interop 88, Sept. 26-30 in Santa Clara, CA. In addition to several formal presentations, including a technical session by Hans- Werner Braun, a fully-functional NSS was on exhibit and used to provide Internet connections to conference participants. This "travelling" NSS will be used in future conference exhibits. by Ellen Hoffman (Ellen_Hoffman@um.cc.umich.edu) NSFNET BACKBONE SITES & MID-LEVEL NETWORK SITES BARRNET BARRNet is entering a major expansion period. The US Geological Survey in Menlo Park and the Xerox Palo Alto Research Center (PARC) were added as "stub" members off the BARRNEt backbone network in September 1988. Scheduled Fall '88 additions included the Monterey Bay Aquarium Research Institute (Monterey, CA), Apple Computer, Hewlett-Packard Labs, 3Com, Excelan-Kinetics and SRI. BARRNet continues to have T-1 link problems the symptom of which is large (intolerable) numbers of receive aborts. The cause is not clear but the problem appears to be in the interaction between the T-1 serial line card and the CSUs. Disconnecting the link and reconnecting generally causes recovery (unless there are other problems present). The problem is being referred to Proteon for their analysis. Much time has been spent in the last two months preparing membership documents (agreements) for use as the legal basis for new BARRNEt members. The base document is in its third revision and expected to be available to interested parties by mid-October at the latest. Bill Yundt and David Wasley represented BARRNet at the first meeting of the California Internet Federation .... a California State equivalent to FARNet. by Bill Yundt (GD.WHY@forsythe.stanford.edu) Westine [Page 9] Internet Monthly Report September 1988 CERFNET We have four node test network that runs IP inside of X.25 connecting the San Diego Supercomputer Center, California State University at Fresno, California Polytechnic State University at San Luis Obispo and California State University at Stanislaus. The net has been up for approximately one month using cisco gateway products. Some problems have be encountered, the most serious being very dated firmware in the SDSC cisco gateway, which is also the gateway to the NSFnet. After some argument with cisco, we received updated ROMs. CERFnet has been running better for the last two weeks. by Susan Estrada (estradas@luac.sdsc.edu) CORNELL UNIVERSITY THEORY CENTER No report received. UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET NCSA/NCSAnet NCSAnet topology remained the same this month, we are working with several schools to try to get them connected within several months (Purdue University, Southern Illinois University at Carbondale). NCSA has been funded for two years to do research and development in the area of switched digital circuits. Specifically, the NCSA Telnet for PC's and Macintoshes will be enhanced so that a switched 56Kbps circuit can be used to connect to a remote host (another PC or a Sun workstation class machine). The availability of cheap switched 56Kbps service in Champaign-Urbana, for example, makes this an attractive offering for those of us without Internet connections to our homes. In addition, we are looking at the possibility of making the NCSA Telnet software (which also supports FTP) run on an ISDN Basic Rate Interface which may be available soon via the campus DMS-100 telecommunications switch. HDLC is the current forerunner for the link-level protocol, however suggestions are welcome. The project is co-directed by Charlie Catlett (NCSA) and Professor Roy Campbell (UIUC Dept. of Computer Science). by Charlie Catlett (catlett@ncsa.uiuc.edu) Westine [Page 10] Internet Monthly Report September 1988 JOHN VON NEUMANN NATIONAL SUPERCOMPUTER CENTER No report received. MERIT/UMNET Merit started implementation of the Merit Inter-Nodal Protocol over IP. Used within the Merit Computer Network, this project will allow Merit to use part of the Internet (for example, the University of Michigan's Pronet 80 fiber optic backbone) for interconnecting Merit Secondary and Primary Communications Processors (SCPs and PCPs). Previously, such interconnections required dedicated lines limited to Merit's internal protocols, while already allowing IP to run on top of Merit protocols. Submitted by Merit/NSFNET Information Services (NSFNET- info@merit.edu) by Ellen Hoffman (Ellen_Hoffman@um.cc.umich.edu) MIDNET No report received. MRNET One new network was attached to MRNet, 129.191 for Network Systems Corp. Another, for St. Olaf College, is just about to be connected. We ceased to advertise one net to UIUC, 192.35.44 (GECRD-ISONET), as GE is now connecting to NSF via NYSERNET, though we are still a backup ARPAnet path. Our connection remains fairly reliable, though we continue to see sporadic problems with "dropouts" on the Proteon link connecting us to UIUC, as well as transient local routing loops related to our use of remote-EGP to get complete NSFnet routing information for our ARPAnet gateway. Neither problem seems related to the NSF backbone. by Stuart Levy (slevy@uf.msc.umn.edu) NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY SATELLITE NETWORK PROJECT (USAN) No report received. Westine [Page 11] Internet Monthly Report September 1988 NORTHWESTNET General: The NorthWestNet annual meeting will be held in Portland, OR, October 10-12. For registration information, contact markwood@vaxf.colorado.edu. Configuration: The network and its links to the Internet seemed quite reliable during September. Boeing Corporation has joined NWnet as a full member, with NWnet providing Internet access to a number of internal systems. Proteon routers at the U of Washington have been upgraded to 8.1x and 1 MB memory; others to follow (DECNET routing doesn't work very well with less memory). Boeing is now providing a secondary domain name server for any NWnet member that needs one. by JQ Johnson (jqj@hogg.cc.uoregon.edu) NYSERNET No report received. OARNET No report received. PITTSBURGH SUPERCOMPUTING CENTER No report received. SAN DIEGO SUPERCOMPUTER CENTER Our upgraded p4200 (new CPU and Ethernet interfaces) has been installed along with 8.1X software. Much better. Now, if it would just advertise via EGP what it learns via EGP... The CERFnet evaluation cisco router has had the firmware on its CPU and X.25 cards updated to current levels - was shipped with OLD versions. Its MTTF has gone from apprx. 9 minutes to many, many hours. (See the CERFnet report for full details.) We have verified the operation of the VMS 5.0 version of SRI's MultiNet TCP/IP package in a multiprocessor (SMP) system (an 8350). Westine [Page 12] Internet Monthly Report September 1988 We are in the process of porting the Network Computing Forum's RPC package to VMS with SRI's MultiNet. We hope to have it in use by 1 Nov. by Paul Love (loveep@sds.sdsc.edu) SESQUINET On September 26th, Guy Almes chaired the initial meeting of a new IETF Working Group on Interconnectivity. This meeting, hosted by Milo Medin of NASA/Ames, focused on how EGP-3 could be used to do inter-autonomous-system routing of significantly more sophistication than currently done with EGP. We (tried to) limit ourselves to strategies that could be implemented within the next 18 months. We will meet again on the first day of the coming IETF meeting in Ann Arbor. 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 In addition we are advertising to NSFnet the following networks in cooperation with the University of Texas: Westine [Page 13] Internet Monthly Report September 1988 UT-Austin 128.83 UT-HSC-Houston 129.106 UT-Arlington 129.107 UT-ElPaso 129.108 UT-MB-Galveston 129.109 UT-Dallas 129.110 UT-HSC-SanAntonio 129.111 UT-HSC-Dallas 129.112 UT-PermianBasin 129.113 UT-CCSPRD 129.114 UT-CHPC-Hyperchannel 129.116 Texas Tech University 129.118 University of North Texas 129.120 UT-SanAntonio 192.6.201 THEnet 192.16.72 and UT-Austin-TestNetwork 192.16.73 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. The triangle connecting UT-Austin, Texas A&M, and Rice University is now up and operational. 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 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 Westine [Page 14] Internet Monthly Report September 1988 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 Tulane University Vanderbilt University Virginia Commonwealth University US Geological Survey University of Virginia Virginia Polytechnic Institute University of West Virginia College of William & Mary SURAnet NETWORKS THAT ARE BEING ADVERTISED TO 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 University Research Association Network 128.169 University of Tennessee 128.172 Viriginia Commonwealth University 128.173 Virginia Tech Westine [Page 15] Internet Monthly Report September 1988 128.175 University of Delaware 128.186 Florida State University 128.192 University of Georgia 128.220 John Hopkins University 128.227 University of Florida 128.231 National Institute of Health 128.239 College of William & Mary 129.6 National Bureau of Standards 129.43 NATIONAL CANCER INSTITUTE 129.57 Continuous Electron Beam Accelerator Facility 129.59 VANDERBILT 129.66 UNIVERSITY OF ALABAMA 129.71 WEST VIRGINIA NET 129.81 TULANE UNIVERSITY 130.11 United States Geological Survey 130.14 National Library of Medicine 130.18 MISSISSIPPI STATE UNIVERSITY 130.39 Louisiana State University 192.5.39 University of Delaware 192.5.45 Fox Chase Cancer Center 192.5.57 University of Delaware 192.5.82 Florida State University 192.5.214 DEC 192.5.215 George Mason University 192.5.219 Clemson Univeristy 192.12.121 FSUCS 192.12.122 FSUCS2 192.16.175 Georgetown Univeristy 192.16.176 Louisiana State University 192.26.10 Gallaudet Univeristy 192.26.11 National Research Laboratory-HUBNET1 192.26.12 National Research Laboratory-HUBNET2 192.26.13 National Research Laboratory-HUBNET3 192.26.14 National Research Laboratory-HUBNET4 192.26.17 National Research Laboratory-HUBNET7 192.26.26 National Research Laboratory-FIBER 192.31.192 IDA/Supercomputer Research Center 192.31.193 Catholic University of America 192.33.115 National Radio Astronomy Observatory 192.41.177 SURAnet Network Operations Center by Jack Hahn (HAHN@umdc.umd.edu) Westine [Page 16] Internet Monthly Report September 1988 WESTNET 1. Ron Uchida, the Executive Director of Colorado Supernet, one of Westnet's state networks, has resigned effective Oct. 15, 1988 to take a position with Sun Microsystems. Colorado Supernet is seeking a highly qualified director, with experience, who can act as a liaison with the Universities and the private sector within Colorado. Applicants will be sought during the month of October. 2. US West has yet to install the T-1 line between the University of Colorado at Boulder and NCAR. This line was ordered in June; we were promised installation within 45 working days. First, US west lost our order. Then, they found it necessary to formalize the agreement with a contract (not mentioned to us as a requirement upon our placing the order), resulting in further delay. Now, they are whining (there is no other word for it) when we ask them to expedite the order, and cite a cost of $20 per day for so doing. This is making even more attractive the possibility of a Colorado state microwave system (projected costs are about 1/3 those of US West). 3. On September 21, a progress report detailing networking in the Westnet region over the past two years was forwarded to NSF. Those interested in being transmitted a TROFF version (sans illustrations), may request one via e-mail from pburns@super.org. 4. Los Alamos National Labatory, connected now for over a month, may be reached at LANL.GOV (128.165). 5. The Second Westnet Annual Technical Workshop is scheduled for Nov. 9 to 11 at the University of Colorado at Boulder. Cisco-specific items will be covered, in addition to a DOMAIN tutorial from Mockpetris, and a SENDMAIL tutorial. There will be a nominal fee for attending (order $30), and attendance is not limited to those with cisco hardware, or those in Westnet. For additional information, contact Carol Ward at cward@spot.colorado.edu. by Patrick J Burns (pburns@super.org) Westine [Page 17] Internet Monthly Report September 1988 TASK FORCE REPORTS ------------------ APPLICATIONS -- USER INTERFACE No report received. AUTONOMOUS NETWORKS Work continues on policy routing summaries and interviews. A task force meeting is being planned for early November and a joint meeting with the Privacy Task Force is being planned for February. Deborah Estrin (Estrin@OBERON.USC.EDU) END-TO-END SERVICES No internet-related progress to report. Bob Braden (Braden@ISI.EDU) INTERNET ARCHITECTURE The next meeting of the INARC Task Force will be held in conjunction with the IAB meeting in Santa Clara, CA, for two days during the week of 9 January 1989. The workshop will include invited presentations by research contributors from throughout the Internet community and especially the IAB and its task forces. Important areas of research interest include policy-based technologies, advanced routing architectures, high-speed networks and interfaces, network management, congestion avoidance/control and advanced transport protocols. Present plans for the first day are for the IAB task-force chairs to present in-depth summaries of past activity and anticipated future work. This will include an assessment of other ongoing work in the area, with special emphasis on issues affecting the growth in size, scope and interoperability of the Internet. On the second day volunteers are solicited to present concise papers of 20-30 minutes in an area of specialization. Appropriate papers may be selected for publication in the ACM Computer Communication Review. Volunteers do not have to be members of the IAB, its task forces or their dependents. Prospective attendees do not have to volunteer a paper, but they must expect to be harassed and caught up in lively discussions. Please send a note expressing your interest and/or paper topic to mills@udel.edu.

PRIVACY The IAB Privacy Task Force had a productive two-day meeting at Xerox Special Information Systems' facility in Arlington, Virginia on 13, 14, and 15 September 1988. Attendees were: Dave Balenson, Curt Barker, Morrie Gasser, RussHousley, Steve Kent, John Linn, Rob Shirey, and Steve Wilbur. Jim Bidzos, of RSA Data Security Inc. (RSADSI), attended the 14 September session. The next PTF meeting was tentatively scheduled for 6 December at BBN Communications, Cambridge, MA in order to review anticipated RFC drafts; this date will be confirmed as work on the RFCs proceeds. Major topics included a review of privacy-enhanced mail implementation activities, followed by discussion of public- key certificate contents, certificate ordering and generation, support infrastructure, licensing issues, certificate management, and specifics of public-key algorithm usage. A paper by RSADSI concerning its anticipated involvement in the certificate generation process was presented at the meeting. The final day of the meeting was devotedto discussion of various privacy-relevant aspects of policy-based routing architectures.
