DAVE CLARK CITED The IAB is pleased to note that IAB member Dave Clark has been selected by Federal Computer Week as one of the "Federal 100" movers and shakers in the federal government systems area. Their citation did not mention Clark's SIGCOMM award last year, nor his contribution to the development the Internet architecture that led the IAB to informally title him "The Internet Architect". The citation in Federal Computer Week [page S17 of the Feb. 25, 1991 issue] reads as follows: David D. Clark Senior Research Scientist Laboratory for Computer Science Massachusetts Institute of Technology You might say Clark is deep in the loop. Since the early 1970s, he has been intimately associated with the design and development of the nation's core data communications framework, first as a developer of the early ARPA network protocols and more recently as chairman of the Internet Activities Board and its research task force. This year, Clark received national attention for heading the National Research Council committee that produced "Computers at Risk," a comprehensive study of hazards facing computers and the data they contain. The report pointed out that computers have becomer more vulnerable because of poor system design, accidents, viruses and other attacks. It also noted that the evolution of computer networks and the growth of computer literacy have added to the risk. Clark was one of the developers of token-ring local area networks which led to current commercial products and was the origin of the IEEE 802.5 standard for token ring networks. He has been associated with MIT's Laboratory for Computer Science since receiving his doctorate from MIT in 1973." B. UPDATE ON INTERNET REGISTRY AND CONNECTED STATUS The policies recommended by the IAB in RFC-1174 ("IAB Recommended Policy on Distributing Internet Identifier Assignment, and IAB Recommended Policy Change to Internet `Connected' Status", August 1990) were approved by the Federal Networking Council (FNC). However, the Defense Communications Westine [Page 3] Internet Monthly Report February 1991 Agency (DCA), which funds the DDN NIC, was not willing to change the registration procedures while a procurement action was in progress to select a follow-on contractor. Subsequently, NSF agreed to consider for sponsorship any networks that wish to be registered under the RFC-1174 rules. NSF cannot provide a "blanket" sponsorship, since each instance has to be validated against existing US government policies. Once the procurement action has been consummated, the implementation of RFC-1174 will be somewhat easier, since the global Internet registry functions now performed by the DDN NIC will have been separated from the DDN registration functions to be performed under the new contract. The details of implementation are still being worked out, but the IAB is confident that the matter is well in hand. At the January IAB meeting, the IAB reaffirmed that the RFC-1174 registration process is necessary for global registration, to support an increasingly international Internet. C. STANDARDS ACTIONS The IAB has taken the following actions on standards since January 1991. The actions are in accordance with recommendations made by the IESG. * OSI Internet Management MIB II to Proposed Standard. * IP over SMDS to Proposed Standard * IP over ARCNET to Proposed Standard Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- Several members of the RG (Cocchi, Estrin, Shenker, and Zhang) have been working on a paper related to the issue of priority pricing in multiple-service internets. Send mail to estrin@usc.edu if you are interested. Westine [Page 4] Internet Monthly Report February 1991 I plan to organize a videconference meeting for May to discuss open issues in inter-domain routing and pricing. If you are interested in these or other related issues, please contact estrin@usc.edu. Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No progress to report. Bob Braden (Braden@ISI.EDU) INTERNET ENGINEERING REPORTS ---------------------------- IETF Report for February 1991 1) The IETF will be meeting at Washington University in St. Louis on March 11-15. The meeting will be hosted by Gurudatta Parulkar. A detailed report on the activities at the St. Louis meeting from the IETF Area Directors will be provided next month. 2) Status Report on IETF Working Group activities. The report below is for February 1991. There is always a great deal of activity right before an IETF. However, activity for the first week of March is not included below. Next month, as part of the report on the St. Louis meeting, we will give a cumulative report for the period from the Boulder IETF meeting (Dec 1990) through the St. Louis IETF meeting (March 11-15, 1991). -- 2 New working groups formed this period X.400 Operations (x400ops) Directory Information Services Infrastructure (disi) -- 3 Internet-Drafts were installed this month (Revised draft (o), New Draft (+) ) (bridge) o Definitions of Managed Objects for Bridges (osids) + X.500 and Domains Westine [Page 5] Internet Monthly Report February 1991 (osinsap) + OSI NSAP Address Format For Use In The Internet -- RFC's Produced RFC1206 (uswg) FYI on Questions and Answers - Answers to Commonly asked "New Internet User" Questions Phill Gross (pgross@NRI.RESTON.VA.US) Westine [Page 6] Internet Monthly Report February 1991 INTERNET PROJECTS ----------------- BARRNET ------- Two new 56 kbps connections and one dial-in connection were added in February, bringing the total number of connected members to seventy-six. An initial cutover to the use of the new T3 facilities and NSS was made in February, but had to be reversed due to bugs in the newest release of the software for the cisco routers in BARRNet's core. The bug was causing the system to fail to route traffic over the previously existing T1 circuits and NSS when the T3 system failed. BARRNet's Administrative Committee approved the addition of a new hub site in the South Bay area, probably to be located at Santa Clara University. This hub, to be implemented in the next 2-3 months, will initially be connected to Stanford University only, but will eventually become part of a separate South Bay loop providing redundant T1 connectivity to all sites connected to the hub. by Paul Baer CICNET ------- The transition to the new CICNet NOC at Ohio State University was completed on Feb. 14th. As part of the operating agreement with AT&T and OSU we also began received monthly network traffic and performance reports. These reports, which are under development by personnel at AT&T Bell Labs, are providing CICNet with detailed analysis of network traffic and performance issues. CICNet held a meeting of its Technical Board on Jan. 31 and Feb. 1. in Orlando, Florida. The meeting was hosted by AT&T and featured a tour of the AT&T internal network NOC and presentations by AT&T personnel on a variety of technical issues. During February Interim Executive Director John Hankins visited Minneapolis and made presentations to groups from the Minnesota Supercomputer Center, the University of Minnesota, and MRNet. Loyola University Chicago became a member of CICNet during February. Westine [Page 7] Internet Monthly Report February 1991 CICNet has finalized a consulting agreement with ANS. The agreement, which runs for three months and began on Jan. 1, 1991, specifies that ANS will provide consulting to CICNet, primarily, in the areas of general management and strategic planning. Pending evaluation by the CICNet Board and ANS, the agreement may be extended beyond the initial three month period. by John Hankins (hankins@cic.net) CORNELL ------- International Connections Equipment has been ordered for the new lines to NORDUNET and INRIA. The line to NORDUNET should be in on March 11th; the line to INRIA should be in on about April 8th. We are currently working out routing and operations agreements. Wide-Area Multicasting At the March IETF we will be presenting our designs for extensions to OSPF and BGP to route multicast packets over the Internet. This will be done in the Working Groups for those protocols. For OSPF we are presenting one solution; for BGP there are several with increasing capabilities for administrative control but also with increasing overhead. Gatedaemon Project Work was done to support variable length subnet masks, including updating the core routing table to properly handle netmasks supplied with route. The routing protocols were updated to provide netmasks when adding routes. Much of this code was generalized so it will work with other protocols, but a lot of it is still IP specific especially when applying netmasks. Much research into radix tree based routing tables needs to be done. The BSD 4.3 Reno reduced radix tree is one option as is the Patricia work done at Network Systems. This recent work will make it easier to support whichever method is used. Extensive testing (although only in the RIP/EGP environments) was done of the work done during the past few months. This has required cleanup and rewrite of some features, such as redirect processing and the kernel interface to fix unintended features (i.e. bugs). A lot of the more recent work is not yet tested. Westine [Page 8] Internet Monthly Report February 1991 Constant contact has been maintained with Dennis Ferguson at the University of Toronto, who has modified the gated BGP v1 to improve performance and support BGP v2 and v3. The intent is to merge this code into the current source as soon as it is available. Dennis claims to be testing his work right now. Scott Brim (swb@chumley.tn.cornell.edu) and Jeff Honig (Honig@chumley.tn.cornell.edu) CSUNET (The California State University Network) ------ We just completed installation of an additional (CSUNET's second) path to BARRnet via a T-1 span from San Francisco State University to Stanford University. This brings the total number of links to the Internet to four (two T-1 links in Southern California via CERFNET and two T-1 links in Northern California via BARRnet). CSUNET is continuing engineering work for the routing paths thru CSUNET to utilize the new T-1 links across the CSUNET backbone, the DWR (The California Department of Water Resources) aqueduct T-1 fiber path (CALiNET), and the four Internet paths. This is an on- going project with BARRnet and CERFnet. Using the Telenet commercial network to CSUNET X.25, BESTNET (Argentina, South America) is now able to gain password protected TCP/IP access to the Internet. During this and the next few months, CSUNET Access Ports (CAP) are being upgraded by Network Operations to provide more reliable student/faculty/staff asynchronous dialup access (up to 9600b/s) to CSUNET X.25 and IP hosts via X.25 PADs. CAP is available for use by CSU students and faculty/staff at all of the twenty CSU campuses. Upgrades to CSUNET this month include a new AGS+ at CSU Fullerton and San Francisco State University. CSU Fullerton now is utilizing the first backbone "ring" T-1 between the Fullerton campus and the Network Operations Center in Los Alamitos, CA (SWRL). X.25, IP, DECnet, and AppleTalk are using the new T-1 path. In order to facilitate early installation of additional T-1 links in the CSUNET backbone "ring", we are looking at using interim equipment. Mike Marcinkevicz (mike_marcinkevicz@qmbridge.CalState.EDU) Westine [Page 9] Internet Monthly Report February 1991 ISI --- INTERNET CONCEPTS PROJECT Bob Braden attended a GIGABIT testbed meeting in Washington D.C., February 12-17th. Seven RFCs were published this month. RFC 1201: Provan, D., "Transmitting IP Traffic over ARCNET Networks, Novell, Inc., February 1991. RFC 1202: Rose, M., "Directory Assistance Service", PSI, Inc., February 1991. RFC 1203: Rice, J., "INTERACTIVE MAIL ACCESS PROTOCOL - VERSION 3" Stanford, February 1991. RFC 1204: Yeh, S., and D. Lee, "Message Posting Protocol (MPP)", Netix Communications, Inc., February 1991. RFC 1205: Chmielewski, P., "5250 Telnet Interface", IBM Corp. February 1991. RFC 1206: Malkin, G., "FTP Software, INC., A, Marine (SRI), FYI on Questions and Answers - Answers to Commonly asked "New Internet User" Questions, February 1991. RFC 1207: Malkin, G., (FTP Software, Inc.), A. Marine, (SRI), J. Reynolds (ISI), "FYI on Questions and Answers - Answers to Commonly asked "Experienced Internet User" Questions", February 1991. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT On February 27th the SPARCstation implementation of VT, the packet voice host, was used in an audio conference over DARTNET connecting five sites: ISI, LBL, MIT, PARC, and UDel. Several additional sites were patched in via an AT&T conference call. The report from participants was that the technical aspects of the conference went smoothly and sound quality was good. For the DARTNET conference, which used no ST-Routers, VT was configured to send duplicate data packets to each of the sites Westine [Page 10] Internet Monthly Report February 1991 participating in the conference. To support multiple connectees without the use of ST-Routers, some additions were made in the (partial) ST-I implementation code within VT. The latest version of the VT source code, which includes these changes, as well as some bug fixes, is available via anonymous FTP; "vt.120.tar.Z" is located on "venera.isi.edu" in the "pub" directory. We will soon make a release of PVP, the packet video host, available through anonymous FTP as well. The final pieces were put in place to support multisite PictureTel conferences with receiver-selected floor control. Because the PictureTel codec can only display one video stream at a time, we had already implemented the ability in MMCC, the multimedia conference control program, to tell PVP which video stream to display as the user directed. This in itself was not enough. Whenever a site switched to a new image, the time for the background refresh to reconstruct the image was too long. We therefore have enhanced MMCC to instruct the PictureTel codec to refresh its video image as needed. MMCC also puts the PictureTel codec into the correct transmission mode (e.g., multipoint or point to point) depending on the number of conference participants. Steve Casner visited David Sarnoff Research Center and Sun Microsystems to discuss possible collaboration on the next stage in packet video -- scaling up to High Definition. At Sun, a talk was presented on "Workstation Conferencing with Packet Video". Steve Casner, Annette DeSchon, Dave Walden, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU) LOS NETTOS ---------- The T1 line supporting TRW's access location change is due soon. Pacific Bell was helpful in giving us an accelerated installation schedule. They are now able to provide B8ZS encoding with no charge on new installs. Walt Prue (Prue@ISI.EDU) MERIT/UMNET ----------- Just before the end of the month, we sent our grant proposal for upgrading our network backbone out to the NSF. As part of our progress toward that upgrade, Western Michigan University is now linked to our network using IP routers rather than the older PDP-11 Westine [Page 11] Internet Monthly Report February 1991 based network nodes. In affiliate news, we have added several new affiliates throughout February: Grand Valley State University, Kalamazoo College, and ArborText, Inc. In addition, Merit/MichNet has been picked to provide network services for FALCON (the Flint Area Library Cooperative Online Network). Saginaw Valley State University will become a Merit member in April, after having been an affiliate for some time. As part of this change, we are now able to provide public dialin in the Saginaw/Bay City area. After extensive work on review and redesign, the MichNet News came out the end of February with a new design and revised editorial policy concentrating more on applications and accessibility for our users. In February, Merit/MichNet added a new feature to the Authorization Server, its user authentication software. Previously, the Authorization Server was used only to authenticate users who wanted to telnet out of MichNet. In February, it began to handle charging for a MichNet service that doesn't have its own charging facilities. In March, the Authorization Server will also allow collect calls from X.25 networks such as SprintNet and Autonet to MichNet hosts that don't otherwise accept these calls; only three MichNet hosts currently do have the ability to accept collect calls from X.25 networks. This will give our users access to all MichNet hosts from public dial-in throughout the U.S. by Pat McGregor MITRE Corporation ----------------- Walt Lazear participated in the organizational meeting of DCA's PSTP working group on Network Management on 6 and 7 February. Shari Galitzer, Forrest Palmer, Mike Saintcross, and Walt attended demos of Trident Systems X-Touch products. The touch screen add on for PCs and workstations are well integrated into X Windows and offer excellent alternatives to mouse driven applications. During the month, detailed briefings and demonstrations were presented. Forrest presented SNMP to Government sponsors and MITRE personnel. Shari presented BBN's MMConf to a similar audience. Her demonstration included a NOC-to-NOC problem solving scenario that integrated the various applications within MMConf. Walt Westine [Page 12] Internet Monthly Report February 1991 presented a CALS like documentation mockup using Framemaker as the display interface. Walt began talks with UUNET (the Alternet provider to MITRE) to introduce OSI CLNP routing into their regional. Extending the OSI protocols on the I.E. Testbed to the attached regional will allow experiments to reach the rest of the Internet that has implemented the OSI infrastructure. MITRE is also designing its internal OSI structure for production usage of GOSIP applications as they become available. Walt Lazear (lazear@gateway.mitre.org) NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NEARnet has grown to 67 members. NEARnet's connection to the T-3 NSFNET backbone has been installed at MIT and testing is currently underway. Two new services were announced in February. Technical staff at member sites are now provided with a guest account on nic.near.net for remote diagnosis of network connectivity problems, and are provided with access to a "mail reflector" for testing mailer configurations. In addition, NEARnet sent the first monthly issue of its online bulletin of user information, "NEARnet This Month", in February. NTM contains news and information about NEARnet, tips on using the network, and a calendar of local and national events of interest. To include an event, send your announcement to nearnet- us@nic.near.net. A document on how to connect Macintosh networks to NEARnet is available in the public ftp directory, "docs", on nic.near.net, under the filename "macintosh-options.ps". by John Rugo NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- The NNSC began the evaluation process for the final version of the NNSC Tour of the Internet project. The NNSC Tour of the Internet is a MacIntosh HyperCard 2 (tm) stack. The NNSC has designed the Tour as a general introduction to the Internet. It contains information on the history of the Internet, network etiquette, Westine [Page 13] Internet Monthly Report February 1991 network applications and resources, as well as a glossary of networking terms. We've designed the Tour for the new network user. We want it to be an easy and enjoyable way to learn about the Internet. We would like to begin distribution of the Tour sometime next month. If you have any questions or would like to receive a copy of the Tour send your request to . The NNSC distributed additions to Chapter 2 of the Internet Resource Guide. The NNSC published the 9th issue of the NSF Network News. The NNSC continues to distribute many copies of both the Internet Manager's Phonebook and the Internet Resource Guide. Both of these publications are available online. For additional information contact the NNSC at nnsc@nnsc.nsf.net. by Corinne Carroll NSF BACKBONE (Merit) ------------------- NSFNET BACKBONE PROJECT (Merit Network, Inc.) During February 1991, the inbound packet count for the T1 NSFNET backbone reached 6,029,601,114 packets. This is an increase of 2.76% over the January total of 5,867,911,410 packets. A total of 2417 networks are configured for announcement on the NSFNET backbone as of the 28th of February. The National Science Foundation announced an addition to Merit Network, Inc.'s NSFNET cooperative agreement which will provide expansion to T3 service for all of the current NSFNET T1 backbone sites not initially scheduled for T3 access. These upgrades will bring T3 service to all 16 sites. A deployment plan and schedule are being developed for the eight additional nodes. Work continues on provisioning T3 service. The T3 Ithaca node was connected into the T3 infrastructure on 25 February. As part of an ongoing review of T3 hardware and network monitoring tools, T3 Technologies and T3 PLUS demonstrated their equipment in Ann Arbor at the Merit Network Operations Center. Representatives of the Merit NOC, IBM and MCI met to discuss the continued growth and evolution of customer service for T3 hardware and software. FDDI interfaces have been deployed at NCSA, Urbana-Champaign; SDSC, San Diego; and PSC, Pittsburgh. Traffic is being actively routed Westine [Page 14] Internet Monthly Report February 1991 at NCSA, while testing continues at SDSC and PSC. Dr. Stephen S. Wolff, Division Director, Division of Networking and Communications Research and Infrastructure, at the NSF, visited Merit Network, Inc. and the Network Operations Center on February 19th. Douglas van Houweling, member of the Merit Network, Inc. Board of Directors, spoke at a conference sponsored by the Office of Technology Assessment on the 14th of February. Elise Gerich, of the Merit Internet Engineering group, attended the February meeting of the FNC-FEPG. Merit/NSFNET Information Services will sponsor a two-day seminar in Ann Arbor, Michigan, May 20 and 21. "Making Your NSFNET Connection Count" will be an informative seminar focusing on issues of interest to campus computing leaders, information systems and networking administrators, educational liaisons, librarians, and educators who want to learn more about national networking. The keynote address will be given by Paul Evans Peters, Director of the Coalition for Networked Information. Carol Parkhurst, ALA/LITA; Al Rogers, The FrEdMail Foundation; Jim Knighton, NASA; John Hankins, CICNET; Dana Sitzler, MichNet; and Douglas Van Houweling, the University of Michigan are among the scheduled speakers. For further information send an electronic message to seminar@merit.edu or telephone 1-800-66-MERIT. Jo Ann Ward (jward@merit.edu) NDRE and NTA-RD --------------- There is nothing to report from NDRE or NTA-RD this month. Anton B. Leere (leere@ndre.no) PREPNET ------- No progress to report this month. PREPNET NIC (prepnet+@andrew.cmu.edu) Westine [Page 15] Internet Monthly Report February 1991 SAN DIEGO SUPERCOMPUTER CENTER ------------------------------ The FDDI concentrator from DEC has arrived - should be in our ring by the time you read this. UC Irvine has turned off their 9.6 DECnet & BITnet link to the Center. Both ar now carried to SDSC via the tcp/ip T1 link of CERFnet; BITnet via the BITnetII code from Joiner Assoc., DECnet via MultiNet's DECnet over tcp/ip software. During January we gatewayed over 190,000 mail messages through our SoftwareTools mail software. Paul Love (loveep@sdsc.edu) SRI ---- In February, we assigned 922 numbers to new IP networks. The total of all IP numbers assigned is now 26,938. The total number of assigned Autonomous System numbers (ASNs) is now 1,224. There are currently a total of 2,449 registered domains which includes 60 at the top level, 2,334 at the second level, and 55 third-level MIL domains. Cumulative Statistics Month/Year Class A B C Total Feb. 1991 39 4,347 22,552 26,938 Jan. 1991 39 4,246 21,731 26,016 Dec. 1990 36 4,305 21,811 26,152 Nov. 1990 35 4,198 21,149 25,382 Douglas MacGowan (macgown@nisc.sri.com) Mary Stahl (stahl@nisc.sri.com) Westine [Page 16] Internet Monthly Report February 1991 UCL ---- Much of the work this month has been to do with setting up pilot IP network services in London & the UK. The London project is based on a fiber net used for Analogue Video, but with a 2 Mbps Data Network overlayed - Livenet Data Network. The UK IP project is overlayed on the current JANET backbone and is called `shoestring'. The Advisory Committee to the JNT reported recently as follows: "At the 1990 Networkshop the JNT invited members of the JANET community to advise it on the response to the requirement within the community for significantly improved interworking with international Internet networks and for a national service to support service using Internet Protocols (IP) across the wide- area network. ... The provision of IP represents a major change in strategy that will have consequences in all aspects of networking in the JANET community, now and in the future, and the DoDAG will continue to study these during 1991. The OSI transition program is an area of particular concern and the group will focus on this in collaboration with other JNT advisory and management groups." It should be stressed that this is a pilot. A Service will not be in place until October. One of the motivations for our involvement has been the wish to extend Packet Video Conferenceing further into the UK. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. The specification and implementation document for the Network Time Protocol Version 3 has been updated with minor revisions as the result of comments from the implementors. While this document was submitted to the standards process some months ago, there is no report on its progress. The new version provides higher accuracy, reliable error bounds and requires reduced network resources. Westine [Page 17] Internet Monthly Report February 1991 2. A preliminary report on our Highball high speed, wide-area network has been completed. The design is based on a high speed crossbar switch and an adaptive, distributed scheduling algorithm. Progress to date in this project includes the design and testing of a suite of scheduling algorithms, construction of a software reservation/scheduling simulator and design of a strawman hardware and software implementation. 3. Erik Perkins, Mike Davis and Dave Mills participated in a DARTnet audioconference using a SPARCstation and ISI packet- voice software, which worked wonderfully. Dave Mills (Mills@UDEL.EDU) WISCNET ------- All sites are now operational. Most of the members have completed integration with the campus environment and are making service available to end users. Two sites are not currently using their connectons. The user services committee completed work on model end user documentation and it was distributed and made available over the net. A series of meetings of user services and consulting staff are planned for March. Michael Dorl (dorl@vms.macc.wisc.edu) Westine [Page 18] Internet Monthly Report February 1991 FOX PROJECT ----------- SRI --- SRI hosted the third meeting of the IETF Directory Services (OSI- DS) Working Group on February 12-13. 17 members attended this productive meeting. Because a majority of the FOX participants attended the OSI-DS meeting, an informal FOX project meeting was held after its conclusion. In attendance were Marshall Rose (PSI), Mark Knopper (Merit), Chris Weider (Merit), Jose Garcia-Luna (SRI), Ruth Lang (SRI). The main topic discussed was how to offer WHOIS information via X.500. Work has been done toward that end. PSI has populated @o=Internet of the White Pages Pilot with FYI and RFC information. Merit has populated @o=Internet with autonomous system and network contact information. In order to work with (rather than against) existing procedures and policies for registration, and advertisement of this information via WHOIS, it was decided that SRI would master a portion of the DIT to maintain the WHOIS information (possibly, @o=Internet@cn=WHOIS). SRI has begun work on identifying the Internet related information that will be transitioned, and on defining how that information will be represented in the Directory. All were in agreement that the fundamental issue which needs to be addressed is one of developing new methods of supporting distributed registration and management of Internet information among autonomous administrations.
