[IMR] IMR88-01.TXT JANUARY 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). BBN LABORATORIES AND BBN COMMUNICATIONS CORPORATION --------------------------------------------------- SATNET The SATNET's performance was very good during the month of January. There were no major unscheduled outages. A scheduled test of new SIMP software early in the month reduced the availability of the SATNET. Tests run by ISI indicate, the Goonhilly site was affected the most. Its availability was 94%. The Tanum, Fucino and Roaring Creek sites all had availabilities of 98%. Westine [Page 1]  Internet Monthly Report January 1988 Steve Blumenthal, Bob Hinden, Karen Seo and John Leddy attended the SATNET/Infrastructure and SATNET Measurement Taskforce meetings at NOSC, San Diego, USA on 1/11-1/13. WIDEBAND NETWORK A number of bugs have been identified and corrected in the BSAT's processor node and channel I/O device software. Some of these bugs were responsible for sporadic BSAT system-level restarts and temporary site connectivity losses which have been observed in recent months. A BSAT software release with the appropriate corrections will be distributed early next month. An effort is underway to determine the sources of unusually large intersite frequency offsets which have been observed in the Wideband Network since its transition to CONTEL ASC's transponder on the Westar-IV satellite. The goal of this activity is to determine which satellite channel subsystem components are responsible for the observed site frequency distribution so that this network parameter can be restored to its nominal range. Too large a frequency distribution can result in degradations in satellite link performance. A coast-to-coast meeting of the End-to-End Task Force was supported by the Wideband Network and the multimedia conferencing facilities at BBN and ISI on January 15. INTERNET RESEARCH & DEVELOPMENT We completed the development of the software for the Low Cost Packet Radio (LPR) interface and are now planning the deployment of Butterfly Gateways for the LPR testbeds. We shipped the Butterfly Gateway for Ottawa. It is configured for 1822, X.25, and Ethernet. A fifth Ethernet interface was added to the Purdue Butterfly Gateway. This brings the total number of interfaces to six. We started working on the software for the VAN gateways. The main issue we are looking at, other than the Telenet certification of the X.25 interface, is how to manage which of the two VAN gateways will advertise a route to network 14 so as to keep the datagrams going to the gateway which has an open virtual circuit. We are also fielding a new Butterfly Gateway software update (Rel. 3.11) which fixes a few bugs which were causing some of the gateways to restart. Bob Hinden (Hinden@BBN.COM) Westine [Page 2]  Internet Monthly Report January 1988 ISI --- Internet Concepts Project Walter Prue attended a meeting at the San Diego Super Computer Center, January 26, and attended a local meeting on the 28th at UCLA regarding forming a Southern California Regional Network. Jon Postel attended the IAB and ICB meetings at the San Diego Super Computer Center, 10-15 Jan. Three RFCs were published this month. RFC 1038: St. Johns, M., "Draft Revised IP Security Option", IETF, January 1988. RFC 1039: Latham, D., "A DoD Statement on Open Systems Interconnection Protocols", DoD, January 1988. RFC 1040: Linn, J., "Privacy Enhancement for Internet Electronic Mail:Part I: Message Encipherment and Authentication Procedures", January 1988. Multimedia Conferencing Project New color video peripheral equipment was received this month for use with the Concept Communications IMAGE 30 codec. Until we receive the codec, the new cameras and monitor are being tested with our experimental codec. The new setup was used for a tele-meeting of the End-to-End Task Force; the second camera, mounted on a copy stand to view printed material, and the larger monitor were both appreciated. Also for that meeting we had a Shure acoustic echo canceller at ISI on loan. This device allowed the ISI participants to listen to a loudspeaker rather than using headphones. While this was a clear improvement at ISI, it may have degraded the sound quality as heard at BBN. More testing is needed with echo cancellers at both sites. Steve Casner (Casner@ISI.EDU) Conversion of the Packet Video Processing program continues in order to make it work with the commercial Image 30 codec by Concept Communications. We received some information in mid- month about some of its operational parameters, and some more at the end of the month. This should be enough to let us the Image 30 codec in its currently-microded form. Dave Walden (DJWALDEN@ISI.EDU) Westine [Page 3]  Internet Monthly Report January 1988 Brian Hung is continuing his work on the echo canceller assembly language program. Currently he is working on a method to convert PCM uLaw to binary code. Brian Hung (Hung@ISI.EDU) NSFNET Project Annette DeSchon and Bob Braden worked on Release 2 of NNStat. This version will correct a number of problems which have been found at various NSFNET backbone sites running Release 1 versions, and will also include a number of new features. For example, remote attach and detach commands will be available, to allow remote adjustment of the statistical configuration or problem diagnosis. Release 2 will be available early in February. Annette also worked on a document describing the Background File Transfer program. Bob Braden attended an IAB meeting held at the San Diego Supercomputer Center, 11-12 Jan, held a one-day video teleconferencing meeting of the End-to-End Task Force, January 15 at ISI. Bob also served as a guest expert on a panel representing they networking needs of the high-energy physics community to review the design of ESNET (MFENET II). This panel met for two days at Cal Tech, 21-22 January 1988. Bob Braden & Annette DeSchon (Braden @ISI.EDU, Dechon@ISI.EDU) Supercomputer and Workstation Communication Project Alan Katz continued work on a split editor under GNU Emacs written in Emacs Lisp.

Please send requests to gomberg@gateway.mitre.org -- be sure to enclose your US Mail address. Gomberg, David A., "A Model of Inter-Administration Network User Authentication and Access Control", The MITRE Corporation, McLean, VA. The purpose of computer communications networks is the controlled sharing of resources among users. While most research, development, and standardization efforts in networking have concentrated on the sharing of resources, the control of this sharing has received much less attention. Many services must be provided to ensure that the proper persons and processes, and only these, are allowed to access the shared resources. These services are usually referred to as network security services. The purpose of this paper is to present a model of technical operations for two closely related network security services: user authentication and user access control. User authentication is the process of verifying that persons are indeed who they represent themselves to be. User access control, as used in this paper, refers to the process of verifying that authenticated users are authorized to exercise particular applications at a specific host. However, access control for specific data (e.g., files) within a host is considered to be a host operating system function that is outside the scope of the model. The model is designed to promote controlled sharing of resources. Particular attention is given to the problems and constraints raised when users and resources are within the purview of different administrations. Chirieleison, Don, "A Communications Protocol for User Authentication and Access Control", The MITRE Corporation, McLean, VA. A model of user authentication and access control has been proposed to promote controlled sharing of resources among a diverse community of computer systems and networks. This report describes a communications protocol that will meet the functional requirements of the proposed model. This document stands alone as a protocol specification but does not repeat the theoretical background contained in the description of the model. The report on the model should be thoroughly read and understood before reading this document. The purpose of the protocol defined in this report is to enable elements of the model to communicate among themselves. It may be used to enable model elements in separate machines within an access control domain to interact. It must be Westine [Page 5]  Internet Monthly Report January 1988 used when model elements in different domains exchange information. It may also be useful for communication between model elements implemented as separate processes on a single machine. Dave Gomberg (gomberg@GATEWAY.MITRE.ORG) SRI --- Transaction Transport Protocol (TTP) Paul McKenney has been implementing TTP on the SUN, including Jim Stevens' ongoing updates to the design. The drivers have been written so that most of the code can be used on both the SUN and the NIU (Network Interface Unit of the SURAN Project). Zaw-Sing Su (ZSu@sri.com) UCL --- Infrastructure: Direct connectivity from UCL to SATNET may disappear in mid Febuary, and this may affect availability of hosts. This may be of concern to anyone who has probes/pingers looking in the European direction. We have a latest release of Diamond, and should be running this very soon. Currently we are running 3.0. Research: Work continues on SATNET TCP performance, and has just started on NETBLT. Currently both TCP and NETBLT are hitting a maximum user data throughput of around 12 kbps. This would seem to be caused by a queue limitation, and we are investigating exactly where this queue limit is. A possible candidate for suspicion is a gateway bunching packets together and causing a SIMPs receive queue to overrun. The Thorn pilot name service is running on all machines at UCL, and provides full O/R name lookup, including a picture service. Westine [Page 6]  Internet Monthly Report January 1988 UCL has designed and implemented an awk based database for account, mailbox and machine configuration management. Distributed access is via NFS. This replaces a previous relational database system, which used ISO Remote Operations for distributed access and update, which was found to be too heavyweight. John Crowcroft (jon@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Traffic on the NSFNET Backbone continued to escalate throughout the month, reaching new levels of unimaginable chaos on 28 January, when two key gateways at U Maryland crashed, leaving only the gateway and fuzzball at PSC to carry the entire load. The traffic was so intense and so overloaded the NSFNET Backbone that it fell into a state very close to complete system collapse. Radical surgery was performed on the fuzzball buffer management system to avoid blocking upstream nodes when storage at downstream nodes becomes so badly fragmented that the preemption policy is unable to find an input buffer of sufficient size. Rebuilding the system after the collapse required crashing nodes from the outside in to break up congestion and then rebooting the system with the new software from the inside out. 2. Work continued on robust clock-synchronization algorithms to improve accuracy and resistance to broken clocks. The fuzzball NTP implementation was modified to include recording and retrieval of delay/offset samples collected from neighbor peers. Using this facility a series of experiments were performed using the five primary radio clocks now operating at ISI, NCAR, Ford Research, U Maryland and U Delaware. The data from these experiments was reduced to scatter diagrams and processed by a number of candidate algorithms, including the median-filter algorithm now used by the fuzzball. Examination of the scatter plots suggested a new algorithm, called the minimum-filter algorithm, which performs better and requires less computational support. It was implemented for the fuzzball and is now in operation at all fuzzball time servers. 3. Further analysis, design and experiment resulted in a clock- synchronization model using a network of hierarchical clocks and algorithms evolved from the majority-subset algorithms suggested in RFC-956, which use a weighted voting technique to cast out broken clocks. The algorithms were implemented for the fuzzball and are now in operation at all fuzzball time servers. In carefully orchestrated tests involving simulated failures the five primary time servers remained synchronized Westine [Page 7]  Internet Monthly Report January 1988 to at least one radio clock, even to the point where all five primary (WWVB and GOES) radio clocks had failed and secondary (WWV) radio clocks at U Michigan and U Delaware kicked in. In other tests the algorithms correctly identified and discarded deliberately broken radio clocks. 4. Work began on a revision of RFC-958, which describes the Network Time Protocol (NTP), to incorporate the latest algorithms and models. 5. Mike Minnich and Dave Mills attended the IAB meeting at SDSC on 11-12 January. Dave Mills attended an NRC meeting on survivable networks in Washington on 19-20 January. Dave Mills (Mills@UDEL.EDU) Westine [Page 8]  Internet Monthly Report January 1988 NSF NETWORKING -------------- NSF NETWORKING UCAR/BBN LABS NNSC As part of the transition plan to the new NSFNET backbone management, Merit representatives Christine Wendt and Jim Sweeton visited the NNSC in mid-January. The discussions at the meeting focused on how the two organizations will work cooperatively to deliver information services to the NSFNET community. All NSFNET mailing lists that the NNSC maintains have been moved to the nnsc machine. Mail to lists such as nsfnet, nsfnet-ops, and nsfnet-responsible-people should be addressed to . By Karen Roubicek (roubicek@nnsc.nsf.net) NSFNET BACKBONE SITES CORNELL UNIVERSITY THEORY CENTER Much of this month's work has been dedicated to stabilization of the NSFNET backbone. Many new networks (see following list) have been added, even though the backbone performance has been inconsistent. Major attention is being given to the problem of the fuzzballs' ethernet interface locking up unpredictably, which in turn, causes major routing problems throughout the internet. At this time the fuzzballs lock up several times daily, and this usually breaks all user telnet connections and times out FTP transmissions. The users are then forced to reinitiate their access routines to whatever node they had been connected to. As a result, the NISC is reporting markedly increased complaints from the users as well as an increase in use of alternate methods of connection to CNSF from users throughout the country. Two people have been added to the staff of the Network and Systems group. Jeff Honig, who replaces Mark Fedor, watches over the gateway daemon and handles complex problems relating to keeping the backbone running well. Martyne Hallgren is working on the Network Outreach program. The NISC is running STATSPY, a program written by Bob Braden and Annette DeSchon, on Cornell, NCAR, and UIUC. STATSPY collects data on traffic between unique source-destination pairs on NSFNET. This is the first time this type of data has been collected on the backbone. Doug Elias is working on a series of analysis and statisical programs which use as input the data collected from STATSPY. These programs will compress the data and generate Westine [Page 9]  Internet Monthly Report January 1988 summary reports. An example of the report generated is shown below. The data shown only represents Cornell traffic. SRC and DEST define a unique source and destination pair. With an identified SRC-DEST pair, #RECS represents the number of times that pair was found in the data sample. The values under FTP, TEL, SMTP, and SRC-Q are the actual number of packets of that type seen in the data sample for that source-destination pair. (FTP - file transfer protocol, TEL - telnet, SMTP - mail, SRC-Q - source quench). The TOTAL represents the percentage the total number of packets for each source-destination pair is over the total number of packets found in the data sample.

Monthly Status Overview: The gateways were available an average of 93.11 % of the time. This represents an improvement over last month. With the exception of the Rochester's gateway (which has been having continuous problems from last month), all the other gateways have been operational. This month we didn't experience any line problem. The only link affected was IAS due to a mux power problem which was corrected promptly, and the TransLAN box at Colorado due to a snow storm. The PSN is still not connected, at this point we don't know when it will be. We are still rerouting all traffic between Penn State and NCAR via JVNCnet and the University of Colorado. The users are very satisfied with the access that they now have to NCAR. Westine [Page 11]  Internet Monthly Report January 1988 The new circuits between JVNC, Yale, Wesleyan, Brown, Harvard, Boston University, Northeastern University, Dartmouth College, and the University of Massachussetts (at Amherst) will be installed in April 9th. We expect short after to bring up JVNCnet service to those institutions, closing the double ring part T1 and part 56kbps. Montclair State College has been awarded a connection to JVNCnet by the New Jersey Department of Higher Education, and it is scheduled for connection by spring time.

There yet remains for the Lab to complete installation and completion of their ethernet equipment and router. Severe problems, apparently from buffer preemption on the local fuzzball, restricted the use of the USAN-NSFnet pathway. The gateway was observed to fail to pass packets for periods ranging Westine [Page 12]  Internet Monthly Report January 1988 from 20 seconds to 5 minutes with this condition occuring with periodicity ranging from 30 seconds to an hour. By Don Morris (morris@scdsw1.ucar.edu) PITTSBURGH SUPERCOMPUTING CENTER Our Fuzzball experienced many problems during January which were apparently congestion related. The links to each of its network partners bounced at least daily. Most often the Fuzzball loses its connection to PSC-GW, even though the ethernet between them appears to be fine and PSC-GW is sending hello packets as expected. This link's bouncing has a great effect on the NSFnet as the primary ARPANET connection is lost for a period of time ranging from a few seconds to a few minutes and the default route shifts from gateway to gateway. A new version of software on Jan. 29th seems to have cleared the problem to an extent, but it remains unresolved. Clock problems early in the month have abated. PSC-GW continues to push the limit of 64 virtual circuits imposed by the ACC 5250 board. Problems with PSN 7.0 software seem to be resolved for our site. New versions of gated and gated configurations have been installed in attempts to close back door routes and stabilize routing. Early in the month a Proteon gateway was installed at Ohio State University but remained unconnected to the internet due to line problems. As of the end of the month, the connection to Ohio State is working and equipment problems are being resolved at Case Western Reserve University which will bring them on line. The local loop on the DS/1 circuit to the University of Michigan is installed and equipment is being sent there for installation. By David O'Leary (oleary@morgul.psc.edu) SAN DIEGO SUPERCOMPUTER CENTER Our PSN's first trunk line (to USC/ISI), installed on 29 Oct.,is still awaiting the Telco folks to come finish testing. The second line to UCLA has just been installed and is ready for Telco testing. Our Proteon p4200 has had its memory increased to 1 meg and is now running 7.4. The combination has resulted in much improved flow. The problem with large FTP'd files to BARRnet, thought to be a Proteon problem, has been resolved to a 1's sensitivity by the Verilink's. We have brought up a 56k line to UC Irvine to connect their campus network to NSFnet. This was via a pair of existing Bridge GS/3's. They will be put into Gated on 12 Feb by the NSFnet NOC. Westine [Page 13]  Internet Monthly Report January 1988 Finally, we are testing a FTP server for our Cray (the client has been operational for several months). The server is based on the work done by NCSA. By Paul Love (loveep@sds.sdsc.edu) NSFNET REGIONAL AFFILIATED & CONSORTIUM NETWORKS BARRNET No report received. JVNCNET (Refer to JVNNSC backbone report) MERIT Merit, MCI, and IBM are making good progress with the preparations for the new NSFNET backbone. IBM is continuing to work on the NSS (Nodal Switching Subsystem) software development, network management, and the deployment schedule. MCI expects all of the data circuits to be installed by the beginning of April. A piece of the circuit for the four-node experimental network has already been installed, with the rest to be completed by the beginning of February. The three partners continued their regular biweekly management meetings. In preparation for the installation of the data circuits and the NSS's, MCI has conducted a site survey of all thirteen mid-level sites and IBM has prepared and mailed out a site survey of its own. We have had discussions with the developers of the University of Wisconsin's OSI implementation (ARGO) regarding the applicability of their code to the new NSFNET backbone. ARGO allows an IBM RT/PC running 4.3/RT to communicate with other computers via the OSI protocol suite. We have installed the code in two machines here for beta testing and anticipate further tests via the bridged USAN satellite network. We briefed the Internet Activities Board this month on the plans for and status of the new NSFNET backbone. IAB members also got copies of the proposal which resulted in our award from the National Science Foundation to manage the new backbone. In other liaison activities, members of the Merit Technical Support Group visited the NNSC at BBN to learn more about their operation and to pursue our working relationship. Other Activities: FTP into and out of MTS (the Michigan Terminal System) is now working and ready to be released to users. This will allow Internet users to communicate with our MTS main frames. Westine [Page 14]  Internet Monthly Report January 1988 MSU (Michigan State University) has moved their 56kbps link to the Internet from their Fuzzball node to their Merit link and is now running their IP traffic through the Merit Network. Both MSU and the University of Michigan are still waiting for the completion of connections to the Purdue ARPANET PSN. By Jessica Yu (jessica_yu@um.cc.umich.edu) MIDNET Midnet is operating quite nicely. The individual campuses are making a lot of progress in getting their local area networks running and connected to Midnet. As a result usage of the network is increasing all the time. Some users have had some problems over the last few weeks with timeouts and slow response times but everyone seems to be getting their work done. We will have release 7.4 running on all of our proteon routers by the second week in Feb. I hope to make some use of SGMP when this happens. Our road show is scheduled for several sites toward the end of Feb. We believe that this will spur quite a lot of interest in using Midnet and the resources it gives us access to.

The following campus networks are being served, and are advertised via EGP to the core: Baylor College of Medicine 128.249 Houston Area Research Center 192.31.87 Rice University 128.42 Texas A&M University 128.194 Texas Southern University 192.31.101 and the University of Houston 129.7 The serial line from NSFnet/NCAR to SesquiNet/Rice has been operational for six weeks, and routes to SesquiNet via NSFnet are now being advertised. Performance is very good. We have had about three outages, typically for two hours each. We have begun testing cisco's support for dual protocol (IP and DECnet) routing. This is strictly experimental. There should be results to report next month. We plan to add Prairie-View A&M University this month.

Proceedings from the November meeting in Boulder are complete (thanks to Allison Mankin, Mitre) and a limited number of copies will be available in San Diego. The goal for March 1 is to have arrangements completed so that copies will be available through the NIC. 3) Since there is a longer than normal period between meetings this time, we scheduled an offline Steering Group meeting in DC for the first week of February. The Steering Group is roughly composed of technical representatives from various government agencies. A rough outline of the topics to be Westine [Page 18]  Internet Monthly Report January 1988 discussed include: - A technical agenda for the IETF (to be used to guide the creation of Working Groups) - Progress of current Working Groups - Relationship with other groups (eg, NPAG) - Meeting dates/locations for the next 4 meetings - How to deal with growth 4) During a progress report on Internet Engineering Task Force activities at the IAB, we discussed the efforts to upgrade the Core EGP servers and some mailbridges with LSI 11/73 CPU's and more memory. This effort has been spearheaded by Bob Enger (Contel). Both BBN and I were able to present data that showed how this simple action made significant short-term improvements in Internet delay and drop rate. I think Bob and everyone else involved in this effort deserve hearty thanks. Bob plans to be at San Diego to give us some more details, like who were all the gracious lendors of the equipment. 5) Four new IDEAs have been installed at the NIC.
