Bob Braden (Braden@ISI.EDU) INTERNET RESEARCH REPORTS ------------------------- AUTONOMOUS NETWORKS ------------------- Discussion continues on the subject of resource usage feedback in internets. D. Estrin and L. Zhang are drafting a related position paper/RFC. In collaboration with S. Shenker (Xerox PARC and E2E Rsch Group) we are planning some related simulation work as well. Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No progress to report this month. Bob Braden (Braden@ISI.EDU) PRIVACY AND SECURITY -------------------- Matt Bishop of Dartmouth College distributed a draft security analysis of Network Time Protocol to the PSRG for review. This report is the result of work initiated during joint sessions between the PSRG and the End-to-End Research Group at the Xerox PSRG meetings in January of this year, and of subsequent consultation over the past months between Matt and NTP founding father Dave Mills. Russ Housley of Xerox presented his work to date on a security labelling framework RFC at a workshop on Security Labels for Open Systems held at NIST at the end of May. A current version of the draft RFC was recently distributed to the PSRG for review. In conjunction with this work, Russ has been invited to speak on a security labelling panel at the 13th National Computer Security Conference in Washington this October. Westine [Page 3] Internet Monthly Report June 1990 TIS has begun distributing its Privacy-Enhanced Mail software for beta test. It is currently in use at TIS offices in Maryland and California, and a phased distribution to other PSRG and IAB member sites (NIST, BBN, NRI) is planned for this month. In the meantime, BBN continues development on hardware and software in support of the P-E Mail registration process, and has been continuing to meet with developers at TIS to exchange and review documentation pertaining to integration issues. The PSRG will meet in Vancouver July 31-August 3 in conjunction with the upcoming IETF meeting, and some joint meetings with IETF WGs are anticipated. An agenda for this meeting will appear in the next PSRG monthly. Ken Rossen (kenr@BBN.COM) COLLABORATION TECHNOLOGY ------------------------ No report received. INTERNET ENGINEERING REPORTS ---------------------------- 1. CNRI is developing a database facility for tracking all online IETF information. When completed, we will be able to provide the capability to query for general information on IETF (including logistics information for upcoming meetings), and for specific information about working groups (including working group objectives, projected dates for accomplishing objectives, meeting minutes, and Internet-Drafts). Not only will this provide a very useful way for interested parties to obtain information about IETF, but it will also serve as a way to track the activities and progress of the numerous working groups. As an example, I will give some information below about IETF activities using tools and data from the database. Thanks go to Greg Vaudreuil (CNRI) for developing the database tools. It is our goal that most of the information now available in the quarterly IETF Proceedings will eventually be available through the database tools and reports. 2. The following information about IETF attendance and growth is from the database. Westine [Page 4] Internet Monthly Report June 1990 Attendance for the last six IETF meetings: - 12th IETF, Jan 1989, University of Texas 121 - 13th IETF, Apr 1989, Kennedy Space Center 112 - 14th IETF, Jul 1989, Stanford University 215 - 15th IETF, Oct 1989, University of Hawaii 138 - 16th IETF, Feb 1990, Florida State Univ. 191 - 17th IETF, May 1990, PSC/SEI/CMU 243 With the exception of the Stanford meeting (which may have been overly large because of proximity to computer industry), this appears to represent a steady growth from the around 100 to over 200 in the last year. Total attendance at these six meetings represents attendance by 500 different persons from 166 different organizations. 3. Repeat attendance by individuals is high enough to show a dedicated core of key IETF contributors. There are 23 persons who have attended all of the last 6 meetings, 28 who have attended 5 meetings, and 46 who have attended at least 4 of the last 6 IETF meetings. That is almost 100 folks who have attended at least 2/3 of the recent meetings. This is impressive when you realize that attendance was only just over 100 for 3 of the those meetings. When the attendees are grouped by categories, we found that about 1/3 were from vendors, about 1/3 from goverment (DoD and civilian agencies), and over 1/4 from universities and regional network operators. 4. Perhaps a more important measure of IETF activity is the number of active working groups and the number of RFCs produced over the same period. The following list shows the total number of working groups and the number which actually met at each meeting: Date Location Total WGs # met - Jan 1989, University of Texas 12 12 - Apr 1989, Kennedy Space Center 19 17 - Jul 1989, Stanford University 20 18 - Oct 1989, University of Hawaii 19 18 Westine [Page 5] Internet Monthly Report June 1990 - Feb 1990, Florida State Univ. 38 32 - May 1990, PSC/SEI/CMU 40 33 - current (for UBC) ~50 Notice that the number of working groups has shown a sharp increase since the creation of the IESG last fall. The IESG first met at the University of Hawaii. After that meeting, the number of WGs doubled. 5. During this approximate period, there were over 80 RFCs published relating to Internet technical activities. Of those RFCs, around 30 pertained to Internet standards. The IETF accounted for almost 30% of the total RFCs published and for ~55% of all RFCs pertaining to standards. The IAB itself, together with the IRTF, accounted for almost another 30%, meaning that the IAB as an organization (ie, including IETF and IRTF) accounted for almost 60% of all RFCs published in this period. 6. The current list of IETF working groups by IESG area is given in Attachment 1. The standard WG abbreviation is also noted. We use the standard WG abbreviation when naming the online files and Internet-Drafts. 7. A history of WG meetings and attendance is given in Attachment 2. 8. A version of this information will be presented and discussed at the UBC IETF meeting.

BOLT BERANEK AND NEWMAN INC. ---------------------------- No report received. CERFNET ------- Connections Testing on a link to the Federal University de Rio de Janeiro began in June. The university will be connected to CERFnet in the near future. The university has a 4.8 kbps connection via New York to UCLA. Eventually, they will be connected to the San Diego Supercomputer Center directly. The Federal University de Rio de Janeiro needs access to the Internet to communicate with researchers at the Latin American Center at UCLA and to access online library and database catalogs such ORION, also at UCLA. The university currently has BITNET access but would like to install a direct link to the Internet. Eventually, the university will serve as a hub for a collection of Brazilian universities that require access to the Internet. Also in June, CERFnet started to advertise routes via IGRP to ESNet. ESNet is connected to CERFnet at the UCLA and Caltech backbone nodes. Installations A new industrial member will be brought online in July. Emulex Corporation, located in Irvine, will have a 56 kbps link to the University of California, Irvine. Emulex builds TCP/IP terminal servers, among other things. Several new sites will begin using DIAL n' CERF in July. Among them are Stardent Computer, Duke Childrens Clinic, and Baker and McKenzie. Westine [Page 12] Internet Monthly Report June 1990 Quarterly Seminar CERFnet hosted a seminar on June 5, "The Future of Computing: Fact and Fantasy" at the University of California, San Diego. This one day seminar was led by Dr.Stephen Lundstrom. The seminar outlined some of the important trends in technology, the direction technological advances need to take, and what capabilities these new advances will provide. New Service CERFnet announced a new product, CERF 9.6, in June. CERF 9.6 is a subscription service at 9.6 kilobits-per-second (kbps), and provides an economical alternative for sites with lower startup needs. This new service eliminates the cost of the gateway box which reduces the initial startup costs. A typical CERF 9.6 member will have only one mainframe computer or similar such as a VAX or MicroVAX. Because there is only one such computer, a gateway to route traffic is not needed. Also, CERF 9.6 lets organizations upgrade to CERF 56 (56 kbps) and CERF 1544 (T1) easily. CERFnet provided Internet connectivity to the USENIX conference in Anaheim. by Karen Armstrong CICNET ------- Four major activities have been at the forefront for CICNet during June: the completion of our FY 1991 Business Plan, the issuance of our Request for Proposals for Network Management and Operations Support Services, the directions issued from our Technical Board, and the announcement by the NSF of a third NSS access point on the CICNet backbone. The Business Plan, which is expected to become effective in July, continues to emphasize the development of end-user applications rather than simply the deployment of technology. The Plan also addresses the relationships between CICNet as the regional network organization and the state or subregional networks functioning within the CICNet states. We believe that our approach will work well in this potentially difficult area. Copies of the Business Plan will be available from CICNet upon approval. Westine [Page 13] Internet Monthly Report June 1990 On June 14, the Bidder's Conference for our NOC services procurement was held in Ann Arbor. Seven organizations were represented, with an additional three organization not in attendance indicating an intention to submit a bid. The closing date for submissions was extended to July 6. A team of four evaluators will analyze the proposals and make recommendations to CICNet. An announcement of award is expected in September. The CICNet Technical Board has created two new task forces: one to guide CICNet's OSI Technology Integration, and the other to plan for an experimental DS-3 network within the CICNet region. Linda Winkler, Argonne National Laboratories, is chairing the OSI task force. No chair for the DS-3 group has yet been appointed. Lastly, the NSF has announced that a new NSFNet node is to be located at Argonne National Laboratories in the Chicago area, and will provide service to and from CICNet. Efforts have already begun in the CICNet Network Planning and Design Subcommittee to accomodate the expansion. by Joel Maloff CORNELL ------- No report received. ISI --- INTERNET CONCEPTS PROJECT Bob Braden chaired a meeting of the End-to-End Research Group at CMU in Pittsburgh, and attended an IAB meeting at BBN in Boston. He also organized and chaired a meeting on the research program on DARTNET. Work was begun on an RFC, with Van Jacobson and Lixia Zhang, concerning TCP extensions for high-speed paths. Greg Finn tested the IP/SQ algorithm using random drop against TCP for equivalently long file transfers. Interference effects between IP/SQ and TCP appear small. A first draft paper that describes IP/SQ performance in the test network setting has been completed. Paul Mockapetris atended the IAB meeting in Boston, Mass, 28 and 29 June. Joyce Reynolds hosted an IETF meeting at ISI, June 12. Jon Postel attended the DEC, ANSI and IAB Meetings, in Boston, MA., 25-29 June. Westine [Page 14] Internet Monthly Report June 1990 Six RFCs were published this month. RFC 1159: Nelson, R., "Message Send Protocol", Clarkson University, June 1990. RFC 1161: Rose, M., "SNMP over OSI", Performance Systems International, Inc., June 1990. RFC 1162: Satz, G., "Connectionless Network Protocol (ISO 8473) and End System to Intermediate System (ISO 9542) Management Information Base", Cisco Systems, Inc., June 1990. RFC 1163: Lougheed, K., (CISCO), Y. Rekhter (IBM), "A Border Gateway Protocol (BGP)", June 1990. RFC 1164: Honig, J., (CORNELL), D. Katz (MERIT)/NSFNET), M, Mathis (PITT/SUP) Y. Rekhter, (T.J. WATSON), J. Yu, (MERIT/NSFNET), "Application of the Border Gateway Protocol in the Internet", June 1990. RFC 1165: Crowcroft, J., UCL, J. Onions, Nottingham University, "Network Time Protocol (NTP) Over the OSI Remote Operations Service", June 1990. Ann Westine (Westine@ISI.EDU) MULTIMEDIA CONFERENCING PROJECT Work continues on porting the Voice Terminal (VT) program to run on a Sun Sparcstation and on upgrading the Multimedia Conferencing Control program (MMCC) to handle multiple codecs and a variety of site configurations. Tim Shepard from MIT LCS visited ISI to learn about the hardware and software we use for packet video. Tim will use the same video codec we do, the Concept Image30, to implement packet video on a 386 PC-AT hardware base. We plan to work together so our implementations can interoperate. Steve Casner, Annette DeSchon, Dave Walden, Eve Schooler (casner@ISI.EDU, deschon@ISI.EDU, djwalden@ISI.EDU, schooler@ISI.EDU) Westine [Page 15] Internet Monthly Report June 1990 FAST PARTS No relevant Internet news from FAST to report this month. Anna-Lena (Alneches@ISI.EDU) JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK --------------------------------------------- No report received. LOS NETTOS ---------- Walt Prue attended the Cisco User Symposium in Redwood City, June 13th and 14th. It gave the attendees a chance to tell cisco what new products and enhancements we wanted to see from cisco. Cisco did appear to be taking note of all comments. Walt Prue attended the Calinet meeting in Oakland June 21st. It appears that Los Nettos and CERFnet will be able to get backup routing of our routes through BARRNET to the NSFNET. The DWR T1 line appears to be close to being brought up and will provide a path to BARRNET. BARRNET has installed OSPF within their network. This will allow them to install the appropriate routing controls to make this alternate path safe from long term routing loops. Los Nettos and CERFnet are still getting only a handful of routes from the ESnet connection at Caltech and none through UCLA's connection. We therefore don't use ESnet for any significant load. Walt Prue (Prue@ISI.EDU) MERIT/UMNET ----------- Continuing with our plans to upgrade the statewide network backbone, Merit staff met with representatives of several vendors who answered our RFI for backbone router equipment. A recommendation for router technology will be made shortly. In the meantime, and in preparation for a faster backbone and better connectivity for our members, Merit is assisting many of our campuses in applying for their own network numbers. This process is proceeding well, and we expect several of our campuses to convert to the new numbers before the beginning of the fall 90 academic term. Several workshops and planning sessions have been held with staff and administrative personnel from member institutions to help Westine [Page 16] Internet Monthly Report June 1990 with planning for changeover of campus network numbers. Expansion of access for educational institutions and research facilities was part of the Merit Board's mandate after their special meeting this winter. To meet these new goals, we have hired new staff members whose main goals are marketing Merit and its services across the state of Michigan. Merit central staff are assisting member staffs with user education issues as well as technical issues, including presentations, planning for documentation changes, and newsletter articles. Pat McGregor (patmcg@merit.edu) MIDNET ------ No report received. MIT-LCS ------- MIT hosted a two-day meeting to discuss inter-domain routing issues. Work also began on development of a version of the video packetizing code to run on a 80386 platform. Chuck Davin (jrd@PITT.LCS.MIT.EDU) MITRE Corporation ----------------- This is a report on the past six months and some of the current activities in Internet Engineering research at MITRE. OSI TRANSITION We have produced a prototype implementation of X Windows in OSI. This prototype implements an Association Control Service Element (ACSE)-based strategy for mapping X to OSI. It was presented at the ANSI X3H3.6 meeting in Durham, North Carolina, April 9-10, and the National MAP/TOP User's Group Meeting in Washington, D.C., May 2-3. With the assistance of Bellcore, the performance results were also put before the European Joint Network Team. For our participation in the University of Wisconsin X.400 pilot project, we have installed the software on a Sun workstation on the Westine [Page 17] Internet Monthly Report June 1990 Internet Testbed. In order for the pilot to be Internet-wide, the participation is with X.400 over TCP using RFC 1006. MITRE will additionally measure the performance of the X.400 over the Wisconsin TP4-CLNP in the Internet Testbed. We are now testing a TP4 module we have written for the MIT Network Simulator. This has congestion avoidance algorithms and mixed DoD and OSI traffic cases among its option settings. INTERNET MEASUREMENT We have completed a report analyzing performance data collected on the Integrated Tactical Demonstration Network demonstration. With traffgen, toptrace, and Slow-start TCP modified to enforce a chosen sending TCP maximum segment size, experiments were carried out on the TCP performance available from paths traversing VSAT, TACSAT, Line of Sight radio, and DAMA links. A paper on the results is to be presented at the SHAPE Technical Centre Military OSI Symposium June 7. INTERNET TESTBED The East Coast Federal Internet Exchange, or FEBA-East, is going to change configurations and the Ethernet connecting the MILNET Mailbridge and NSS 9 will no longer be located at MITRE. The Defense Communications Agency Internet Testbed has had to find a new way to reach NSFNET. As of early June, testbed connectivity will be through a fractional T-1 link with Alternet. We are using the testbed now to do multiple topology testing of the DEC-bit implementation for BSD TP4-CLNF. University of Maryland testing of the UNIX OSPF implementation is continuing. Allison Mankin (mankin@gateway.mitre.org) MRNET ----- No report received. NCAR/USAN --------- No report received. Westine [Page 18] Internet Monthly Report June 1990 NEW ENGLAND ACADEMIC AND RESEARCH NETWORK ----------------------------------------- NSF announced in early June that NEARnet has been awarded an NSS, which will be connected to the NSFnet at T3 rates. Details of the installation are not yet final but it is anticipated that the connection will be established during the fall of this year. NEARnet is actively investigating the use of dark fiber in its metro Boston hub, to run at FDDI speeds. This change could be accomplished in the same time frame as the installation of the NSS. Shiva Corporation, Banyan Systems, Atmospheric and Environmental Research Corporation and the Massachusetts Regents Computer Network were connected to the network during June. NEARnet has experienced significant problems with the current connections to the NSFnet through the JvNCnet. The JVNCnet operator is aware of the problems and is in the process of upgrading its equipment to resolve them. NEARnet has completed its start-up phase. It reached financial self-sufficiency at the end of June, demonstrating that high quality network services can be provided at a cost which is attractive to members. It will continue to maintain a high standard of service and to add new services, particularly in the applications area, that can be of benefit to its members. Laura Breeden (breeden@SH.CS.NET) NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Karen Roubicek attended the FARNET Meeting at NRI in Reston, VA. The NNSC distributed several copies of the Internet Resource Guide, NSF Network Newsletter, and NSFNET posters at the Special Libraries Association meeting in Pittsburgh, PA. The Interim NSFNET Acceptable Use Policy and the NSFNET Expansion Announcement have been added to the list of online documents on the NSFNET portion of the Info-Server. To retrieve either of these documents send a message to: info-server@nnsc.nsf.net. In the body of the message type: request: nsfnet, topic:nsfnet-acceptable-use, topic: nsfnet-expansion.jun.90. by Corinne Carroll (ccarroll@nnsc.nsf.net) Westine [Page 19] Internet Monthly Report June 1990 NORTHWESTNET ------------ Ron Johnson, Co-principal Investigator for NorthWestNet; Eric Hood, Chairman of the Technical Committee; and Dick Markwood, Project Director visited NSF on June 21 to report on NorthWestNet to the NSF Networking Staff. The presentation focused attention on large distances that NorthWestNet traverses to serve its constituents and on the related costs of circuits. The public telecommunications infrastructure is largely underdeveloped or non-existent in large areas of the six member states. For example 56 kbps circuits have not been available in North Dakota and Montana until within the last month. The presentation also highlighted features of the NorthWestNet Strategic Plan expected to be completed in July. The link between Seattle WA and Fargo ND was upgraded from 19.2 Kbps to 56 Kbps on the 28th. by Dan Jordt NSF BACKBONE (Merit) ------------------- The NSFNET Backbone inbound packet count for June, 1990, totalled 3,272,564,511 packets. This is an increase of 3.78% over the May total of 3,153,325,456 inbound packets. The number of networks announced on the NSFNET backbone increased to 1639 at the end of June. The National Science Foundation announced a $7.9 million expansion of the NSFNET. In addition to adding three new nodes to the backbone, data transmission speed on several key links of the existing network will be increased to 45 million bits of information per second. The sites that will be linked by the new higher speed connections are Cambridge, MA, Ithaca, NY, Pittsburgh, PA, Ann Arbor, MI, Urbana-Champaign, IL, Argonne, IL, San Diego, CA, and Palo Alto, CA. The new nodes on the NSFNET backbone network will be located in Cambridge, MA, Argonne, IL, and Atlanta, GA. The Cambridge node will be at the Massachusetts Institute of Technology and will connect the New England Academic and Research Network (NEARnet) to the NSFNET. Argonne National Laboratory, located near Chicago, will provide connections to ANL and additional connections to CICnet, which serves institutions in the upper Midwest. The Atlanta node will be at Georgia Institute of Technology and will provide additional connections to the Southeastern University Research Association Network, SURAnet. Westine [Page 20] Internet Monthly Report June 1990 The NSS relocation at Ithaca (NSS 10) was rescheduled for the week of July 1. College Park (NSS 9) is scheduled to be relocated the week of July 9 and Princeton (NSS 8) the week of July 16. It is planned that none of the sites will be completely isolated for extended periods of time as the changes take place. Any questions may be directed to the regional network or nsfnet-info@merit.edu. An NSFNET Technical Seminar was held in Ann Arbor, MI on June 21 and 22. Members of the Merit/NSFNET partnership addressed topics of network analysis and latencies, OSI in the NSFNET, and T3 technology and plans for the NSFNET backbone. Guest speakers were Van Jacobson, of LBL, on network performance considerations, Darleen Fisher, of NSF, on gigabit testbeds, Joel Replogle, of NCSA, on advanced graphics applications, and Dory Leifer, of U of M, on internetworking with ISDN. A technical meeting for EASInet was also hosted on June 22. The process by which international networks register for an IP address and network status is now facilitated by addressing requests to IP-register@merit.edu. Foreign nets requesting network status as a member of CA*Net, JANET, IRIS, Inria, EUnet, EASInet, DFN or Nordunet are encouraged to use this procedure. The replacement of IDNX equipment with Cylink ACSUs was completed and work continues on an OSI implementation. The SRI-NIC and NSFNET staff have been working to better rationalize the manner in which Milnet hosts are announced on the backbone. The Border Gateway Protocol (BGP) has been implemented between CA*Net and NSFNET, on the link from Toronto to Ithaca. BGP is documented in RFCs 1163 and 1164. Glee Cady, manager of Merit/NSFNET Information Services, spoke about the current state of the NSFNET to attendees of Networking '90, the Canadian Networking Conference hosted by the University of Victoria, British Columbia. Eric Aupperle, President of Merit Computer Network, Inc., represented Merit/NSFNET at the FARNET meeting. Hans-Werner Braun, principal investigator on the NSFNET project, and Elise Gerich, of Merit/NSFNET Internet Engineering, attended the FEPG meeting. Hans-Werner also attended a meeting of the IAB. Elise participates on a committee with Scott Brim, of the Cornell University Theory Center, and Tony Hain, of ESnet, to draft an architecture for the NREN.

Westine [Page 22] Internet Monthly Report June 1990 SRI ---- DDN NIC In June, we assigned 158 new numbers to government-sponsored IP networks and 106 numbers to new independent IP networks. The total number of all assigned IP numbers is now 5,001 which includes 2,872 sponsored networks and 2,129 independent networks. The total number of assigned Autonomous System numbers (ASNs) is now 690. There are currently a total of 1,741 registered domains which includes 49 at the top level, 1,644 at the second level, and 48 third-level MIL domains. Douglas MacGowan (MACGOWAN@NIC.DDN.MIL) SURANET ------- No report received. TEXAS HIGHER EDUCATION NETWORK ------------------------------ No report received. UCL ---- Jon Crowcroft attended the End2End meeting at CMU. Protocol Migration: Work continues on NTP and ROS. A paper was presented at Networks 90 on an implementation of a mapping of X Windows communication onto OSI. Work on hybrid Analog/Digital conferencing included integrating a laser video disk system for quality image storage and retrieval into our model conferencing system. Policies: We are trying to model the policies for the agencies involved in the UK-US "Fat Pipe" upgrade so that we can simplify the enforcement (of access as well as share policies) without impacting on cost benefits of sharing. Its difficult! John Crowcroft (j.crowcroft@CS.UCL.AC.UK) Westine [Page 23] Internet Monthly Report June 1990 UNIVERSITY OF DELAWARE ---------------------- I am proud to say our efforts on behalf of the Internet community have been faithfully reported each and every month since the inception of the Internet Monthly Report many years ago. However, our efforts are primarily to support research and only secondarily to support infrastructure. The nature of other contributions to this report, as well as the perceived needs of the readership, have led us to alter the nature of our own contributions. In future only activities important to the conduct of collaborative experiments and infrastructure will be reported. Our research activities and results will be reported as usual in various technical reports, symposia and archival publications. No progress to report this month. Dave Mills (Mills@UDEL.EDU) UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET -------------------------------------------------- No report received. WESTNET -------- 1. Two new sites were added to Westnet: George Washington High School in Denver, CO and Unisys in Salt Lake City, UT. 2. The circuit between Colorado State University and the University of Colorado at Boulder (UCB) has been upgraded to T-1. The circuits between the University of Colorado at Colorado Springs and the University of Colorado at Denver (UCD), and UCD and UCD are in the process of being upgraded to T-1. 3. Utah has formed a state network UNet. It has the initial mandate to provide interconnectivity for all university libraries within the state, 4. Westnet has entered into a software maintenance agreement with cisco. We are in the process of collecting serial numbers for gateways and terminal servers within the region. Westine [Page 24] Internet Monthly Report June 1990 5. There will be a Westnet Steering Committee meeting July 20, 1990 at the University of Denver beginning at 10:00 AM. Interested parties are invited to attend. by Pat Burns, pburns@csupwb.colostate.edu, Carol Ward, cward@naiad.colorado.edu WISCNET ------- Articles of Association, policies for acceptable use, and membership policies were drafted. The Articles of Association were approved at a June 26th meeting of the board of directors at Carroll College in Waukesha. A second draft on the Site Planning Guide was developed and distributed at the June 26th meeting. Orders for a 56k DDS line, DSUs, and routers to support the test connection between UW-Madison and UW-Platteville were issued in early June. We expect to begin installation in late July. Evaluation of communication services bid responses were completed and tentative winning vendors were selected. Actual awards and orders for communication services are delayed pending discussions with the Wisconsin Department of Administration concerning possible use of their T1 network. Bids for TCP/IP hardware and software for IBM mainframe and mid- size hosts were received and analyzed. A new award was made to Intel and old contracts with IBM and Interlink (formerly ACC products) were updated. Michael Dorl (dorl@macc.wisc.edu) Westine [Page 25]
