Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- No progress to report. Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No progress to report. Bob Braden (Braden@ISI.EDU) PRIVACY AND SECURITY -------------------- The Privacy and Security Research Group spent much of November recovering from the incredibly productive meeting in October, the description of which prompted me to way overstep my allotted half-page in this space last month. In the area of Privacy-Enhanced Mail, representatives of BBN, RSADSI, and TIS have been coordinating with regular conference calls to track the progress toward the Internet distribution. At least 12 sites now have P-E Mail beta test software. A general distribution is now expected for some time in Spring 1991. In the meantime, BBN will be working on certificate- issuing software and hardware and TIS will be finishing the mail processing software to reflect updates to the protocol (see next paragraph). Progress at the October meeting and the continued heavy volume on the "pem-dev@tis.com" mailing list has been keeping the RFC 1113-15 editors (Balenson, Kent, Linn, Rossen) busy. Publication of the revisions as Internet Drafts is now planned for January 1991. Westine [Page 3]  Internet Monthly Report November 1990 Other editing and review activity occurring behind the scenes involves Rob Shirey's draft of an Internet Security Architecture, and a review of comments and a new document returned by the SNMP Authentication draft authors. Addditional RG comments on the SNMP documents were sent to the authors in late November. Ken Rossen (kenr@BBN.COM) COLLABORATION TECHNOLOGY ------------------------ It is with considerable regret that I must announce the passing of the CTRG. From June 1987 through February 1990, the CTRG held 8 full meetings, three special working group meetings (on audio servers, desktop video, and connection architectures), and is felt to have strongly influenced R&D efforts at most of its members' institutions. Activities spanned the general areas of user interfaces, multi-media technologies, and, of course, collaboration technologies--in particular, desktop teleconferencing. For approximately the last 18 months of its active life the CTRG also served as collaboration technologies- -in particular, desktop teleconferencing. For approximately the last 18 months of its active life the CTRG also served as a vehicle for promoting the development and deployment of collaboration technologies on a national scale. The CTRG was disbanded not for lack of a continued need for a working group covering its areas of interest. Rather, with the demise of Olivetti Research California and my move into start-up land I was unable to continue as chairman, and no other member felt they could afford to succeed me. I encourage anyone in the larger community who has the necessary resources to take a shot at rebuilding an equivalent group.

Orders were also placed for the next four 9600 bps dedicated lines, following completion of the evaluation of the first such circuit. Six new applications for membership were received and approved, bringing the total membership to 81,of which 70 will be connected by the end of December. Work is continuing on the installation of the MCI DS-3 microwave and the associated equipment for the upgraded NSS at Stanford University. Activation has been postponed from the projected late November date until mid-December. As of the end of November, BARRNet is running OSPF on 11 of the 14 "core" routers, with the other three scheduled for cut-over as soon as we receive upgraded Ethernet boards. Also, a redundant T1 link between Northern and California, using fiber provided by the California Department of Water Resources, is scheduled to go into full operation shortly according to a plan implemented by the California Internet Federation (CalINet), to which BARRNet belongs. by Paul Baer BOLT BERANEK AND NEWMAN INC. ---------------------------- Terrestrial Wideband Network (TWBNet) and ST/IP Gateway Video conferencing was used heavily in November. There were a total of 16 conferences and demonstrations. Of these, 7 were multipoint connections -- one 4-site conference and six 3-site conferences. The remaining nine were point-to-point. Two conferences were held with UCL in London, UK. Conferences were held for discussions in the following areas: IETF User Services Area, IETF Router Requirements Working Group, Autonomous Networks Research Group, Dartnet experimenters, and ACTS/Gigabit Studies. Conferees included Mark Pullen, Peter Kirstein, Ira Richer, and Paul Mockapetris. ST gateways were also used to support SIMNET exercises among 3 sites, Ft. Rucker, AL, Orlando, FL, and the Air Force Human Resources Lab at Williams AFB in Phoenix, AZ. These were held to Westine [Page 9]  Internet Monthly Report November 1990 demonstrate SIMNET during the I/ITSC show in Orlando. Work continued on preparations for the new "southern loop" to be added to the TWBNet. This will provide added robustness in the form of an alternate path between the east and west coasts and will also allow shorter tail circuits to Southern sites such as Ft. Rucker and Los Alamos. Current plans call for Wideband Packet Switches (WPSs) to be installed in Mobile and Albuquerque. Inter-Domain Policy Routing We are currently organizing two separate IDPR "testbeds" - one at USC and another at SAIC. The purpose of these testbeds is to provide facilities where we can perform our integration testing and where we can exercise the IDPR protocols without disrupting other users. Most portions of the IDPR protocol suite have already been integrated and tested at USC. Once BBN becomes fully attached to DARTNET, we will continue our IDPR experiments using DARTNET. Internet O&M / ICBNet Infrastructure US Internet connectivity for the "Human Genome Project", a cooperative international research activity, was implemented this month via the 384 Kbps shared-bandwidth channel of the US-UK fat pipe. No IP routing problems have been experienced in the US Internet. However, the circuits implementing the US-UK shared fat pipe channel were re-routed by the international carriers from the TAT-8 cable to a backup satellite link for the majority of November. The US-UK fat pipe provides connectivity to the ULCC, UCL, RSRE, STC, WPC, and NTA ICBNet sites. A break currently exists in the TAT-8 cable which is expected to be repaired in early December. IP routing configuration changes are being put in place that will allow backup routing to the US Internet for various ICBNet sites via the NORDUNET connection at the NTA site. This backup capability will be automatically used during outages in the US-UK fat pipe. It should first be implemented and tested for the RSRE site next month; other ICBNet sites will then follow. Jil Westcott (westcott@BBN.COM) Westine [Page 10]  Internet Monthly Report November 1990 CERFNET ------- Three new industrial facilities will be connected to CERFnet in January. Micro Technology (Anaheim, CA), Sparta Inc. (Laguna Hills, CA), and Unocal Corporation (Brea, CA) will connect to the network via 56 kilobits-per-second (kbps) leased line circuits to the node at the University of California, Irvine. In December, CERFnet will install a new backbone node in San Jose, California. This node provides access to the Internet through a T1 leased line circuit to the University of California Office of the President (UCOP). UCOP is connected to the San Diego Supercomputer Center (SDSC) where CERFnet is connected to the NSFNET. On November 29, from 8:30 a.m. (PST) to 10:40 a.m. (PST) CERFnet suffered a major network outage. A MCI fibre cut isolated sites beyond the San Diego-area from the NSFNET. These sites, however, did have connectivity to one another. The AGS cisco Systems Gateway Servers at SDSC were upgraded to AGS+. The remaining AGS servers at the other CERFnet backbone nodes will be upgraded in December. Karen McKelvey (mckelvey@sds.sdsc.edu) CICNET ------- In early November CICNet held a meeting of scientific computation support personnel from CICNet member institutions. The meeting included a review of the scientific computational facilities at each site as well as presentations on parallel processing and scientific visualization. The next meeting of this group is scheduled for March, 1991. CICNet staff members John Hankins and Kimberly Shaffer managed an exhibit at the annual meeting of the Radiological Society of North America. The meeting, held from Nov. 26 through Nov. 30 in Chicago, IL had attendance of over 40,000. The exhibit included two Sun workstations linked via a cisco Systems router and56 kbs circuit to the Internet. The exhibit, developed and staffed in conjunction with Merit/NSFNET, MichNet, and CERFnet, provided a live demonstration of some of the many resources available via the Internet to the meeting attendees. During early November CICNet completed negotiations with AT&T and Ohio State University on a three year contract to provide CICNet Westine [Page 11]  Internet Monthly Report November 1990 with Network Operations Center services. NOC services are currently provide by Merit, Inc. The contract, which became effective Nov. 15, includes a 90 day transition period. Active monitoring is expected to be implemented by AT&T/OSU in December with the transition from Merit services to be completed by early February. Personnel changes - Joel Maloff, formerly Executive Director of CICNet, has joined ANS as Vice President for Client Services. The CICNet staff wishes Joel good luck in his new role. John Hankins has assumed Joel's responsibilities on an acting basis. Paul Holbrook, currently a staff member at CERT, will be joining the CICNet staff as technical manager in mid-December. by John Hankins CORNELL ------- No report received. FARNET ------- FARNET has had a busy couple of months. In September, a meeting was held in Boulder, Colorado to discuss various topics of interest to FARNET. Proceedings from this meeting should be available by mid-December and can be obtained by sending e-mail to roblesc@farnet.org. At the meeting, FARNET decided to write an RFP for a consultant to help write a strategic plan. During November, the RFP was let and Northeast Consulting Resources, Inc. was selected. New officers for calendar year 1991 were elected. The results are as follows: Glenn Ricart - chair Joel Maloff - vice chair (resigned due to job change) Bill Yundt - treasurer Tom Bajzek - secretary A new election will be held prior to the next meeting to elect a new vice-chair. The next FARNET plenary meeting is scheduled to be held in Las Vegas on January 14 and 15 with the primary topic of discussion being the strategic plan. by Susan Estrada Westine [Page 12]  Internet Monthly Report November 1990 ISI --- INTERNET CONCEPTS PROJECT Bob Braden attended the End-to-End research group meeting at Stanford University, Stanford, Ca., November 7-11, 1990. An automated tool for testing the configuration of DNS nameservers was developed. The first implementation, "Doc", is a shell script which uses "dig" to query the nameservers for a specified domain. Doc (version 1.0) primarily tests that delegation information is consistent between the authoritative and delegating nameservers for a given domain. Doc is available for anonymous ftp from venera.isi.edu, file: pub/doc.1.0.tar.Z The latest version of the DNS query tool ("dig" version 2.0) was also made available for anonymous ftp from venera.isi.edu, file: pub/dig.2.0.tar.Z. This version includes support for zone transfer, a more convenient way to make an address to domain name query, and various bug fixes. Four RFCs were published this month. RFC 1191: Mogul, J., (DECWRL), S. Deering, (STANFORD), "Path MTU Discovery", November 1990. RFC 1192: Kahin, B., "Commercialization of the Internet, Summary Report", Harvard, November 1990. RFC 1193: Ferrari, D., "Client Requirements For Real-Time Communication Services", UC Berkeley, November 1990. RFC 1194: Zimmerman, D., "The Finger User Information Protocol", Center for Discrete Mathematics and Theoretical Computer Science, November 1990. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT Now that the ST protocol specification is an RFC, we have turned our attention to the application program interface. Through teleconferences and e-mail, we have been working with BBN to design extensions to the BSD socket interface to add the ST protocol. Westine [Page 13]  Internet Monthly Report November 1990 The SPARCstation version of the teleconferencing system is on the brink of being released. Many refinements were made to both the packet voice host, VT, and the packet video host, PVP. These included more complete microphone and speaker control in VT, and PVP performance improvements. To accommodate interoperability between Butterfly and SPARCstation versions of PVP, the Butterfly version was enhanced to allow byte swapping of video data. This feature will allow big-endian SPARCstation PVP's to communicate with little-endian Butterfly PVP's. The multimedia conference control program, MMCC, was changed to support multiple conference rooms at BBN. This is an example of the need to support different site configurations. Toward this end, we worked with Tim Cowans at UCL on a generic video server interface that will allow MMCC to control different types of video crossbar switches. We are also considering rewriting the control program to be more easily configured. MMCC now uses feedback via the host control protocol, HCP, to ensure that voice and video connections are successfully completed. Extensions were also made to HCP to control stream selection in VT and PVP. This will be used by MMCC during multisite PictureTel codec conferences to select which PVP video stream to display, since only one video stream can be displayed at a time. As part of a panel on "Collaborative Design", Eve Schooler gave a presentation about the ISI/BBN Multimedia Conferencing Project at the IEEE International Conference on Systems, Man, and Cybernetics in Los Angeles. Steve Casner participated in the workshop on Network and Operating System Support for Digital Audio and Video at ICSI in Berkeley.

Her email address is waters@nisc.jvnc.net. The next JvNCnet regional meeting will take place January 25, 1991 at the Computer Science Building at Princeton University. Megabytes, the JvNCnet newsletter will be distributed very soon. Its purpose is to inform, acquaint and familiarize our current, potential users, and other individuals interested in networking about information, activities, and programs concerning the JvNCnet. In addition, the newsletter will communicate issues and events concerning the global Internet. We welcome the opportunity to have our users and readers collaborate and participate with us on this newsletter. We feel collaboration is a necessity in order for us to produce the best newsletter, one that provides a wealth of helpful and useful information. We also want to make it interesting reading. Availability for the month was 99.46%. The average network uptime for the six month interval May 1990 to October 1990 equals 99.37%. The amount of traffic (in billions of packets) equaled 3.57 (incoming: 1,773,111,727 and outgoing: 1,733,125,315). The figure of 3.57 reflects an increase of 23% compared to September's traffic. JvNCnet ranks first this month for the amount of traffic sent to the NSFnet. Approximately 850 million packets were transmitted and it represents 16.17% of the total NSFnet traffic. Router configurations for the default route on a number of ENS gateways were changed to ensure these gateways would not lose connectivity to the JvNCnet if the route for the NSS was lost. Planning is in progress for a network reconfiguration. The plan includes firmware upgrade, software upgrade, new BNS model and topology changes. Significant improvements in backbone topology, overall performance and capacity, and robustness will result from the reconfiguration. The new backbone shape will decrease the backbone routing diameter and upgrade switching performance. Westine [Page 15]  Internet Monthly Report November 1990 For providing economical Internet connectivity for small institutions and individuals, Engineering has started a SLIP pilot project. In development stages are addressing, security, store- and-forward mails, and other value-added services for SLIP connections. Trinity College, located in Storrs, Connecticut, has been connected to JvNCnet. Rochelle Hammer LOS NETTOS ---------- Nothing unusual to report in Los Nettos this month. Walt Prue (Prue@ISI.EDU) MERIT/MICHNET ------------- Significant progress has been made on the initial backbone upgrade experiment. Routers have been installed at Oakland University, Wayne State University, The University of Michigan, and Michigan Tech. Additionally, we have installed a 56K link between MTU and UM, substantially improving service to that university. Expected to be added to the new backbone soon are WMU, MSU and UM- Flint. In other news, the asynchronous PPP protocol code is now being loaded into production on terminal server nodes. MichNet staff participated at the Internet booth at the Radiological Society of North America conference in Chicago, along with representatives from CICNet, the Merit/NSFNET project, and CERFNet.

Karen Roubicek and Corinne Carroll gave an presentation on introducing the Internet to researchers at the Harvard Herbarium. by Corinne Carroll Westine [Page 17]  Internet Monthly Report November 1990 NORTHWESTNET ------------ The NWNet Annual meeting took place Nov 14-17, and the focus of the meeting was to enumerate and discuss the strategic goals of our regional network as we look to the next decade of internetworking. Key components of these goals included: o A focus of providing programmatic support for other complimentary regional development projects. It is recognized that other regional efforts in distributed health care, economic development and educational renewal can benefit from the telecommunications and programmatic infrastructure provided by NWNet. o Formation of a Customer Services Committee to peer with the existing Technical Committee in an advisory role to the Executive Board. The realization is that the services needs of the our widening customer base are as important as the technical problems faced in running a regional network. o A dedication to bring internetwork access to the K-12 community either through the selection or emulation of successful programs in place at other regionals. o To increase the reliability and robustness of NWNet connectivity while reducing the operational overhead of operating and managing NWNet, it was recommended by the Technical Committee that NWNet provide, maintain, and manage all necessary equipment for connection to the regional. o To facilitate the successful implementation of the new directions and promotion of the new programs presented in the strategic plan, the NWNet Board of Directors has created an Executive Director's office. In other news, the Fred Hutchinson Cancer Research Center in Seattle was connected to NWNet via T1 to the University of Washington, and the UW-Seattle to OGI-Portland connection was upgraded from 56kbps to T1. by Dan Jordt Westine [Page 18]  Internet Monthly Report November 1990 NSF BACKBONE (Merit) ------------------- The count of packets coming into the NSFNET Backbone during November 1990 was 4,857,386,823. This represents a 7.40% decrease from the October 1990 total of 5,245,630,461 packets. As of November 30th, 2125 networks are configured for announcement on the NSFNET backbone. IBM's newly developed T3 router has been deployed at four sites on the NSFNET backbone, where T3 testing continues successfully. An architectural change has been implemented so that the NEARnet router peers individually with NSS 8 at Princeton. Visitors to the Merit/NSFNET Network Operations Center included Jean-Luc Borsotto of France Telecom. Eric Aupperle, President of Merit Network, Inc., attended the Information Infrastructure for the 1990's conference held at Harvard University. Glee Cady, Manager of Merit/NSFNET Information Services, and Ellen Hoffman, assistant to the President of Merit, gave presentations on Michnet and NSFNET at the University of Western Ontario, London, Ontario, Canada. Glee also spoke to the New York State Department of Education on internetworking and the NSFNET project. Laura Kelleher, of Merit/NSFNET Information Services, was its representative to the second meeting of the Coalition for Networked Information. The mission of CNI is to promote the creation of and access to information resources in networked environments in order to enrich scholarship and to enhance intellectual productivity. Laura participated in the Directories and Resource Information Services working group. The three-day conference, "Making Your NSFNET Connection Count," was presented by Merit/NSFNET staff and national and regional experts in networking November 12 -14th in Ann Arbor, Michigan. More than 80 educators, reseachers, and administrators attended the seminar which encouraged participants to use available NSFNET connections to foster education and research. Pat Smith and Susan Calcari, of Merit/NSFNET Information Services, were on hand to discuss internetworking and the NSFNET Backbone Project with attendees of the 76th Annual meeting and conference of the Radiological Society of North America held in Chicago, November 25-30th. As part of InfoRAD, an instructional and informational exhibit presenting topics of interest to radiologists as a whole, Westine [Page 19]  Internet Monthly Report November 1990 representatives from Merit/NSFNET, Merit/Michnet and CERFNET demonstrated internet resources with connectivity provided through the University of Chicago and CICNET. Susan Hares, of Merit/NSFNET Internet Engineering, attended a meeting of Westnet, presenting information on the current state of the backbone as well as plans for T3 and OSI implementation. Elise Gerich, also of Merit/NSFNET Internet Engineering, attended the Australian Academic and Research Network workshop in Sydney, Australia where she spoke on the current state of the NSFNET and plans for implementing T3. Elise also spoke to network operations and user services staff at the University of Sydney about NSFNET and Merit/NSFNET NOC and IS services.

PREPNET ------- During November, Wilkes University and Pine Creek Software joined PREPnet. Wilkes University will be connected to the Scranton hub at 56Kbps, and Pine Creek Software will be connected to the Pittsburgh hub at 56Kbps. On November 13th, PREPnet held its second Annual General Member meeting in Philadelphia. Seventy people attended the meeting. Topics included: security issues, suggestions for informing faculty members about the uses of PREPnet, and special projects at member sites. Westine [Page 20]  Internet Monthly Report November 1990 Tom Bajzek, PREPnet's Executive Director, attended a three-day workshop on "Information Infrastructure for the 1990s" at Harvard University. PREPnet NIC (prepnet+@andrew.cmu.edu) PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- The PSC has received, and is in the process of installing, all FDDI equipment needed to peer with the T-3 NSS. The PSC is currently reconfiguring its machine room to accommodate T-3 equipment. The gigabit Ultra link between the PSC (site of NSS#5) and the Westinghouse Energy Center (site of the Cray YMP) has successfully been used as a transport mechanism for both graphical data and IP traffic. Equipment is currenly on order which will allow interconnection of the Ultra link and FDDI networks at each site. The number of networks announced by the PSC to the NSFnet is now 44, an increase of 4 since our last report. Greg Dobrich SAN DIEGO SUPERCOMPUTER CENTER ------------------------------ No report received. SESQUINET --------- No report received. SRI ---- DDN NIC In November, we assigned 2,114 numbers to new IP networks. The total of all IP numbers assigned is now 25,382. (This includes numbers that fall within assigned "blocks" and numbers that were previously tagged as being "unconnected"). The total number of assigned Autonomous System numbers (ASNs) is now 1,190. Westine [Page 21]  Internet Monthly Report November 1990 There are currently a total of 2,159 registered domains which includes 54 at the top level, 2,051 at the second level, and 54 third-level MIL domains. Four new top-level domains have been registered: the People's Republic of China (CN), the Arab Republic of Egypt (EG), Hungary (HU), and South Africa (ZA). Seventy-three new second-level domains were registered in November. NIC staff have been working with Matti Rendahl at the Royal Institute of Technology in Stockholm, SE, to assist with the activation of a root domain name server for Europe. On a related note, after being off the net for over a month in order to undergo a system upgrade, the host GUNTER-ADAM.AF.MIL was reactivated as a root domain name server on 9 November.

UCL ---- Professor Kirstein and Steve Kille had a video conference with Paul Mockapetris between UCL & DARPA/Wahington to discuss Directories and other work. ULCC/UCL and BBN had a video conference to discuss some operational problems and some possible further users of UK-US connectivity. Westine [Page 22]  Internet Monthly Report November 1990 Several IETF dratfs and other documents were issued by Steve Kille on IETF Directory Work, including: IETF Directory Working Group Scope (Version 3) S.E.

John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. DARTNET is now alive and kicking at UDel. Our DARTNET router is hooked to our research net DCNET, which bristles with SPARCstations, fuzzballs, PCs and timekeeping paraphernalia. Mike Davis systematically solved problems with misconfigured smartjacks, noisy cables and feisty interfaces only after gobs of hardworking overtime. Westine [Page 23]  Internet Monthly Report November 1990 2. An initial configuration for DARTNET time servers has been built, including primary time servers at ISI and UDel. Local routes were forged at ISI and UDel so that the primary servers can reach DARTNET, although these routes are not published elsewhere. Initial observations suggest that timekeeping within the DARTNET community can probably be maintained to better than a millisecond as long as the SPARCstations are not stressed with lots of disk traffic. 3. The specification document for the Network Time Protocol (NTP) Version 3 has been forwarded to the IETF for processing. The Version-3 protocol has been running in the fuzzball time servers for several months and is backward-compatible with earlier versions. Version 3 provides more accurate time, cer- tifiable error bounds, a revised clock-selection procedure, including algorithms developed by Marzullo and Owicki, and an adaptive-parameter local- clock model which significantly reduces network overhead. Dave Mills (Mills@UDEL.EDU) UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET -------------------------------------------------- No report received. WESTNET -------- No report received. WISCNET ------- Meetings with WiscNet site technical staff were held in Wisconsin's four LATAs to discuss site preparations for WiscNet. Sites have been busy installing TCP/IP software and electronic mail user and delivery agents on their various (primarily DEC VMS) systems and are now fairly well prepared for the advent of the network. The design of the network has been finalized. It consists of a well connected fractional T1 backbone riding on the State of Wisconsin Department of Administration's T1 network with 56K DDS end node sites connected to the backbone through central office multiplexing equipment. A committee of user service staff has been formed to prepare some "model" documentation. It's intended that this documentation set Westine [Page 24]  Internet Monthly Report November 1990 will be a starting point for each site to use in preparing its own end user documentation. We'd like to hear form anyone who might have developed a similar documentation set. All equipment has been ordered with delivery expected in mid- December. T1 lines between the State of Wisconsin Department of Administration's T1 network and WiscNet's backbone sites have been ordered. 56K DDS lines will be ordered soon. We expect to have the backbone and a few end node sites operating in early to mid- January and to have all sites operational by the end of January. We'd like to hear from anyone using cisco routers with Tellabs or AT&T T1 multiplexors.
