 IAB MESSAGE
 
      The IAB held a video teleconference on April 26, 1990.  Minutes of
      this meeting are still in preparation.  The following decisions
      were made at this meeting.
 
      A. CONNECTIVITY
 
         Permission to connect to the Internet is currently controlled by
         Federal agencies that fund much of the US Internet
         infrastructure.  To handle the increasing number of
         international connections, the IAB will recommend to the Federal
         Networking Council (FNC) that they:
 
            o  Tolerate delegated responsibility and informal controls in
               the near term.
 
            o  Develop policy-based routing for the long term.
 
         The US-centric nature of the administrative actions to connect a
         new network to the Internet could be significantly improved as
         the number of international IP connections increases.  The IAB
         will draft recommendations on distributed connection procedures
         for FNC.
 
      B. ANSI STANDARDIZATION OF CORE INTERNET PROTOCOLS
 
         As announced last month, procedures are being worked out between
         the IAB and the ANSI group X3S3.3 to turn the core Internet
         protocols -- IP, ICMP, TCP, and UDP -- into ANSI standards.  The
         IAB proposes that the process be to:
 
            o  Assemble the existing documents, without trying to rewrite
               them.
 
            o  Remand any technical problems or NO votes back to the
               IETF/IAB.
 
         Other Internet protocols might be submitted to ANSI for
         standardization in the future, but only after they have reached
         a final stage of development and Internet standardization.
         Parallel development in ANSI and IETF should not take place,
         although joint work may be appropriate in some cases.

      C. PROPRIETARY PROTOCOLS
 
         The question was discussed: under what conditions, if any,
         should a vendor proprietary protocol be designated an Internet
         standard?  The following two requirements were agreed upon:
 
            o  The IETF and IAB must believe that such a standard is
                needed for the operation and evolution of the Internet.
 
            o  The standard must be under full IETF/IAB control.  If it
               is a vendor proprietary protocol, the IAB must have a
               letter from the owner giving the IETF change control over
               the protocol.
 
      D. STANDARDS
 
         The standards actions taken at the meeting were listed in last
         month's IAB REPORT.
 
         Since the teleconference, the IAB has taken the following
         additional standards actions, following IESG recommdations:
 
            o  The Point-to-Point Protocol (PPP), RFC-1134, was approved
               for advancement to Draft Standard state.  Designation of
               the PPP Options document as a Proposed Standard is awaiting
               review of its security provisions.
 
            o  The Border Gateway Protocol (BGP), defined by a pair of
               documents -- the protocol specification and an Internet
               application description -- has been designated a Proposed
               Standard.

      PRIVACY AND SECURITY
      --------------------
 
         The initial version of the reference implementation of Privacy-
         Enhanced Mail per RFCs 1113-1115 will begin beta test in the
         coming month among PSRG members and the IAB, thanks to the
         efforts of TIS.  BBN has begun development work on hardware and
         software in support of the registration and certificate
         management process in the distribution version of P-E Mail, and
         has been meeting with RSADSI to establish procedures for this
         process.  In the meantime, a list of anticipated changes to the
         RFCs has been compiled by David Balenson, reviewed by PSRG
         members, and distributed to the "pem-dev" mailing list.
 
         Additional activity among PSRG members has included an increased
         effort, in cooperation with IETF Security AD Steve Crocker, to
         review protocol security facilities proposed by IETF WGs (e.g.,
         telnet).  To this end, the PSRG is planning its next meeting at
         UBC in conjunction with the upcoming meeting of the IETF.

      INTERNET O&M
 
      An implementation plan has been developed for the connection of the
      TWBNet to the "FIX-West" ethernet, located at the NASA Ames
      Research Center.  This connection will support all routing between
      the DARPA TWBNet/ICBNet networks and the remainder of the Internet,
      after the ARPANET is terminated and until the FIX-West connection
      is supplemented by the connection of the TWBNet to "FIX-East" at
      SURANet/UMd.  The implementation plan includes the relocation of
      the video/multimedia conferencing system currently operating at SRI
      to RIACS facilities, with the associated ST gateway support to be
      located at Ames.
 
      Phil Park and Steve Storch attended the IETF meeting, held at the
      Pittsburgh Supercomputer Center, May 1-4.
 
      TCP-TP4 PROTOCOL TRANSLATION
 
      Hunter Barr has come on the project to work with live network
      interfacing.  He is getting the X.25 interface up on a test
      machine, and then will begin coding some interfacing to the
      protocol conversion.  We have been expanding the ISO interface to
      the Estelle code, and beginning the definition of interface between
      the protocol conversion and the live networks, both for the TCP and
      ISO sides.
 
      J. Wilkes of SHAPE T.C. has expanded the finite state machine
      definitions in Estelle to include most of the TCP and TP4 opening
      and closing transitions.
 
      REAL-TIME MULTIMEDIA CONFERENCING
 
      Release 3.0 of the BBN MMConf Multimedia Conferencing System is now
      available.  The MMConf system allows multiple people on different
      workstations to collaborate over text documents, rasterfiles,
      generated maps, terminal-based applications, video tools and
      presentations made up of all of these tools.  Release 3.0 includes

 Internet Monthly Report                                         MAY 1990
 
 
      these changes from previous versions:
 
       o   The conferencing infrastructure has been made more robust.
 
       o   The text editor has been significantly improved.  It is now
           possible for any participant to easily include new private
           files or paste text from other private windows into the
           conference windows.
 
       o   The text editor now supports viewing and sketching over
           rasterfiles.
 
       o   The presenter, a tool for organizing and making presentations
           or "talks", has been significantly improved.  It is now much
           easier to manage multiple talks and to add new slides created
           from private information.
 
       o   This release includes a set of tools for managing video
           resources and conferencing over them.  Programs include servers
           for managing shared video resources for multiple clients
           distributed over a local area and applications programs for
           accessing and displaying the video information.  Applications
           include a video map navigator, a video database browser, a tool
           for creating and editing video edit decision lists (as well as
           directly controlling video devices) and a tool for dubbing from
           one device to another.
 
       o   This release includes binaries for Sun3's and Sun4's running
           Sunview and for Sun3's and Sun4's running the X11 window system.
 
      The complete list of tools distributed with this release includes:
 
        mmconf       The conference manager.
        in.confd     The conference daemon.
        presenter    The talk creation and presentation tool.
        mmslide      The text and rasterfile editor/viewer.
        viewshell    A terminal emulator.  The application run by
                     the emulator only runs at one site in the
                     conference. This tool makes it possible to run
                     any terminal-based program in the conference.
        sketch       A simple sketching tool.
        Xnavigate    A video map browser.
        vlens        A video database browser.

      INTERNET ROUTING
 
      We completed the Inter-Domain Policy Routing (IDPR) protocol
      specification document and distributed it to members of the
      Internet community for review.  At the May IETF meeting we gave
      tutorials (in our working group) on the architecture and on the
      protocol suite.  As we proceed with implementation, we are awaiting
      detailed comments on the IDPR protocol suite, which was well-
      received at the working group meetings.  Protocol implementation
      has been split between people at USC and people at BBN.  We expect
      to complete implementation in August and begin experiments in
      October.
 
      TERRESTRIAL WIDEBAND NETWORK AND ST/IP GATEWAY
 
      During May, the ST Gateway and Terrestrial Wideband projects
      supported 3 SIMNET exercises/tests, eight video conferences and
      three conferencing demos.
 
      One of the video conferences included four sites, two involved
      three sites, and eight involved two sites.  Conferences were held
      by the Internet Open Routing Working Group, members of DARPA, and
      NIST OSI Implementor's Working Group on Security and Network
      Management.  This month we also introduced echo cancellers at ISI
      and at DARPA.  These echo cancellers permit the use of room audio
      speakers.  Previously, room echos were avoided through the use of
      personal headphones.
 
      SIMNET activity included the support of three two day exercises.
      One of these exercises was held to demonstrate the system during DC
      area Armor Conference.  This month we also supported the first
      simultaneous usage of the Terrestrial Wideband Network by a SIMNET
      exercise and a two way video conference.

      As a result of activities begun in the CICNet Video Applications
      Study Group, aproposal has been submitted to the National Science
      Foundation for the "Parallax Project", a program designed to
      evaluate the impact of a unified Europe, circa 1992, on research,
      educational collaboration, and business relationships.  At the same
      time, or in "parallel", the effectiveness of various electronic
      information transport techniques will be evaluated.  This includes
      electronic mail, database access, compressed video and full motion
      video. By the end of 1992, the 12 member states of the European
      Community will have integrated their economies with one another
      forming a "Unified Europe". A team led by Professor Steve Acker,
      Ohio State University, representing CICNet and our members, has
      proposed research on the impacts of a unified European economy,
      focusing on both the technical and social issues of collaboration
      theory. The proposed research includes industrial and academic
      participation, as well as American and European partners. More
      information on this project is available through CICNet.

      INTERNET CONCEPTS PROJECT
 
      The majority of testing of the IP/SQ algorithm in a small network
      setting is now finished.  The results are being written up.
      Essentially, the testing regime had four senders simultaneously
      transferring one Mbyte through a congested gateway with no
      limitation (no window) to transmission speed except Source Quench
      feedback from that congested gateway.  Hundreds of test runs were
      done.  If random drop is utilized in the gateway, across a range of
      round-trip delays from 0.02 to 1.0 seconds with multiple senders,
      the algorithm utilized 86% of available gateway capacity with a
      std. dev. of 6%.  The algorithm is also quite fair in conjunction
      with random drop.  As gateway capacity was changed during testing,
      the amount of source data transferred was altered to keep the ideal
      fair completion time constant.  Mean completion time was 854
      seconds with a std.  dev. of 89 seconds.

      Current Implementation and Future Evolution", in a symposium given
      by Technology Transfer Institute in Washington, D.C., 18-22 May,
      1990.  The topic of the symposium was "TCP/IP and OSI: The
      Interoperability Challenge".  Braden's talk was mostly concerned
      with the technical limitations of the TCP/IP protocol suite and the
      current and projected efforts in IETF and IRTF to address these
      limitations, significantly extending the domain and lifetime of
      TCP/IP.

      MULTIMEDIA CONFERENCING PROJECT
 
      PictureTel video codecs have been installed at the ISI and DARPA
      teleconference sites, and additional units will be installed at BBN
      and SRI soon.  These codecs provide better video quality, but can
      only be used for 2-site teleconferences for now.  The existing
      Concept codecs are still available in parallel for multi-site,
      multi-quadrant teleconferences.  Switching between codecs, and
      between 12th-floor and 1st-floor conference rooms at DARPA, is
      controlled by the MMCC user interface on the conference workstation
      plus RPC-based codec and audio/video switch servers.
 
      NEC echo cancellers have also been installed at ISI and DARPA, and
      were first put to official use during a telemeeting of the IETF's
      ORWG on May 29th.  The echo cancellers eliminate the need for
      conference participants to wear headphones at these sites.
 
      A new debugging feature has been added to the Packet Video Host,
      PVP, to intentionally mis-order, delay or drop out-going packets in
      a specified pattern.  This feature has been helpful in testing the
      new packet-reordering algorithm.  Progress continues on porting the
      Voice Terminal (VT) program to run on a Sun SPARCstation, working
      toward the goal of personalized conferencing.
 
      Several multisite conferences and demos were held again this month.
      One of the demo groups, PIs for the National Photonics Center,
      would like to use teleconferencing to coordinate the Center's work.

      This month a great deal of effort has been concentrated on the new
      statewide network backbone upgrade. A RFI went out to interested
      vendors at mid-month, with results expected in a few weeks.
 
      Along with the backbone redesign, a major upcoming problem is
      resolution of ourrouting complications due to multiple access
      points (CICNET and NSFNET) intothe Internet. Currently, all the
      Merit member institutions share a single ClassA address (35.0.0.0),
      and this does not allow for optimal routing. Several of Merit's
      member's campus networks are looking at getting class B and class C
      addresses, to help get more efficient and reasonable routing for
      their campuses. To that end, Merit is sponsoring a workshop on
      practical steps which should be taken to get new addresses,
      configure the campus nets more efficiently, and other local
      troubleshooting. This workshop will be held in early June in Ann
      Arbor, and many of the Merit members' technical and user staff will
      be attending.
 
      Our authorization server to allow access off net 35 (Merit) from
      dialin and public ports, as well as allowing charging for
      surcharged services to previously inaccessible nodes, is in beta
      test mode now.  We expect this service to come online within the
      next few months.
 
      Merit has been working on an appropriate use policy for its
      statewide infrastructure and a draft has been submitted to the
      board of directors for their consideration and approval at their
      June board meeting.

      The T1 link to the NSFnet backbone was down for several hours one
      night. Discussions were held with both our carrier and our router
      vendor concerning strategies to avoid and more quickly correct a
      similar outage.
 
      The P4200 supporting three sites died.  It took eight days to get
      the router back in operation.  About the only lessons to be learned
      are the value of common equipment, (which the P4200 is not), and
      hot spares, (which we don't have for the P4200).  Credit is due
      Jeff Wabik for persistence in finally repairing the router.
 
      The MRNet NIC was moved to Supercomputer Systems Engineering and
      Services Co. (SSESCO) space about 50 feed away.  The temperature of
      the MRNet room dropped about eight degrees, satisfying the primary
      objective of the move.
 
      The next MRNet general meeting is tentatively scheduled for
      Thursday, July 26.  The agenda is expected to include:
 
      o    Election of an MRNet chair
 
      o    Discussion of the MRNet Executive Committee's vision for the

      initially be IP only, providing distributed access to an SQL
      database engine running on a Bull mainframe.  Planned
      implementation date is July 1990.  Discussion centered around
      OSSHENet providing circuits (multiples of DS0) to NWNet, rather
      than the sharing of routers or router ports.  Once a working
      relationship is established at this level, perhaps more
      collaboration will result.
 
      On May 22, 23 and 24 in Seattle, there were face to face meetings
      of a number of NWNet committees.  The Training Committee met the
      first night, mostly in preparation for the NWNet annual meeting in
      which the regional members have theopportunity to send
      representatives from the User Services area and from the research
      community.  The Configuration Subcommittee worked on issues
      regarding router upgrades, OSPF integration, policy requirements
      for NWNet connections, low cost services offerings, backdoor
      connections to MRNet and ESNet and operational concerns. The
      Technical Committee meeting then addressed issues relating to

      As of 31 May 1990, the number of configured nets on the NSFNET
      Backbone totals 1591.
 
      Plans for facility upgrades at four nodes on the NSFNET backbone
      will necessitate NSS relocations.  The sites involved are Ithaca
      (NSS 10) the week of June 25, College Park (NSS 9) the week of July
      9, Princeton (NSS 8) the week of July 16, and Seattle (NSS 14) the
      week of August 6.  Members of the Merit, IBM and MCI technical
      staffs are involved with these moves to assist in minimizing any
      disruption in service.  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 by contacting nsfnet-info@merit.edu.

      The Ultranet link from the Pittsburgh Supercomputing Center (site
      of NSS#5) to the Westinghouse Energy Center (location of Cray YMP)
      described in our last report has been brought up to full (1
      gigabit) capacity over single mode fiber.  Experimental data will
      soon be used to exercise this link and determine its performance
      characteristics.
 
      The number of networks connected through the PSC NSS and PSCNET
      increased by six since our last report.

      We have begun using the UltraNet's frame buffer code in production
      on our Y-MP.  Problems remain with TCP/IP services over the Ultra
      and with its "tsock" service.

      ESnet software has been moved to a production VAX.  We continue to
      use the NSFnet link to NERSC - the direct connection should be
      inplace by the end of June (via the General Atomics ESnet
      connection).

      In May, we assigned 49 new numbers to government-sponsored IP
      networks and 141 to independent IP networks.  The total number of
      all assigned IP numbers is now 4,721 which includes 2,677 sponsored
      networks and 2,044 independent networks.  The total number of
      assigned Autonomous System numbers (ASNs) is now 677.
 
      There are currently a total of 1,676 registered domains which
      includes 48 at the top level, 1,580 at the second level, and 48
      third-level MIL domains.

      The infrastructure for the UK tails of the upgraded UK-US links are
      now mostly tested. A 2nd video conferencing room is nearly
      prepared, and a Lab for video work has been set up.
 
      Work on our very own distributed networks simulator is now well
      under way.  We are studying ways to reproduce/verify the MIT FQ and
      virtual clock results. The question is being asked - "What is the
      analogy video source that is conformant with the network congestion
      control algorithms, in the way that a >4.3BSD TCP is "conformant"
      with some network mechanisms"?
 
      A third JANET site (Cambridge) has joined in the NTP over ROS peer
      community.  UCL are bidding for a decent clock.
 
      The X Windows protocol work over other Comms Stacks has thrown up
      an interesting finding - a research implementation of X.25 on
      Ethernet was measured to be within 2% user data throughput of TCP
      on the same machines - unexpected to say the least; further
      investigation is deemed necessary.

      1.   Paul Schragger demonstrated initial simulation results of the
           routing algorithm proposed for our gigabit project. The
           provocative simulation scenario involves the existing NSFNET
           backbone network topology with the sites connected by 1-Gps
           fibre loops. Erik Perkins, Mike Davis and Ken Monington
           produced a detailed report on the experimental VLSI crossbar
           chips for the project. The project sprouted two new

           contributors, Professor Charles Boncelet and grad student
           Alden Jackson. Charlie's field is algorithms, especially those
           used in digital signal processing, while Alden is working in
           routing technology.
 
      2.   Our DARTNET connection via the DC point-of-presence is now
           operating. Paperwork has been completed to acquire a
           SPARCstation for use as a router.
 
      3.   Using a precision timer board built by Stefan Levie,
           appropriate statistical procedures and exquisite care, Ken
           Monington managed to determine the frequency offset of our
           cesium clock at minus 170 nanoseconds per day relative to the
           East Coast LORAN-C chain. While this represents the
           culmination of a lot of hard work, he does not consider even
           this degree of precision sufficient for use in NTP to measure
           continental drift.
 
      4.   Mike Davis completed a report on a statistical study of NSFNET
           backbone network delays. Mike is using correlation methods to
           pry forth subtle interdependencies in time and space which
           might prove useful in characterizing congestion events.
 
      5.   Further work on the NTP specification and implementation
           continues.  After a good deal of simulation and experiment,
           the new algorithms have been implemented and tested in the
           fuzzball time servers now operating in the Internet. The
           results indicate a worthwhile improvement in robustness and
           accuracy, while at the same time providing reliable
           indications of correctness and timekeeping quality to the
           users of the service. The specification (RFC-1119 as amended)
           has been updated and will soon be circulated for review.

      We received official notification from the NSF that our proposal
      has been funded.
 
      The WiscNet Board met 5/2/90 at UW-Eau Claire.  The agenda included
      a proposal for a test installation between UW-Madison and UW-
      Platteville, mebership policies and fees, and appropriate use of
      the network.
 
      Bids for DSU and multiplexor equipment and for communication
      services have been received and are currently undergoing analysis.
      Awards will be made in early June.
