IAB TASK FORCE REPORTS
----------------------
 
     APPLICATIONS -- USER INTERFACE
 
        The task force met June 13-15 at Bellcore in Red Bank and
        Morristown, NJ.  Significant topics of discussion included audio
        servers, floor control in the context of real-time
        teleconferencing, connection architecture, and broadband
        testbeds.  Further details will hopefully appear in the next
        monthly!

     AUTONOMOUS NETWORKS
 
        ANTF is planning for a small meeting in July in conjunction with
        ORWG.  Plans are underway to begin experimental implementations
        of various Policy Routing functions.  Our next two-day meeting
        will be in September or October on the East Coast.
 
        Deborah Estrin (Estrin@OBERON.USC.EDU)
 
     END-TO-END SERVICES
 
        The End-to-End task force met on June 7-8, 1989 at Lawrence
        Berkeley Laboratory (LBL), hosted by Van Jacobson.  Major
        discussion centered on three topics.
 
        Congestion Control
 
            Scott Shenker described research on congestion control, and
            in particular on Fair Queueing, at Xerox PARC.  Dave Clark
            and Van Jacobson each described their work on congestion
            control, and the group then held a lively discussion of
            these issues.
 
            Gateway queueing algorithms control the interactions among
            the different source hosts' datagram streams; this
            indirectly controls congestion through the operation of the
            end-to-end flow control of the hosts.  Shenker presented
            analysis and simulations demonstrating the performance
            benefits of Fair Queueing (FQ), resulting from the
            insulation it provides between sources.

            Jacobson advanced the thesis that a "sufficiently
            complicated net" will exhibit a phase transition leading to
            large spatial oscillations of traffic.
 
            The following questions emerged from the discussion:
 
            1.  Is FQ too fair?  (How about large server hosts with
                multiple connections?)
 
            2.  How rapidly is steady state reached, both in theory and
                practice? For example, if steady state is reached very
                slowly, theoretical stability results may not be very
                useful for real systems.
 
            3.  For a steady-state traffic pattern, can we devise a flow
               control algorithm that will prevent long-lived oscillations?
 
            4.  Can we demonstrate the phase transition phenomenon, by
                analysis and/or simulation?
 
            5.  Do the gateways need to estimate time constants and
                actively anticipate congestion, in order to damp
                oscillations?
 
        VMTP
 
            Dave Cheriton reported on some further thinking he has been
            doing on VMTP.  He outlined some changes that would modify
            the protocol without changing the external model (user
            interface).  The proposed changes are designed to improve
            efficiency (lower overhead and delay) for larger transfers,
            and embody a partitioning of functions between those that
            are performed seldom and those required for actual data
            streaming.
 
            VMTP now supports the socket routine "select", to provide an
            asynchronous interface.
 
        IP Multicasting
 
            Steve Deering reported on progress of IP multicasting work.
 
            *  An IP multicast Mazewar program will be out very soon.
 
            *  IP multicasting is being installed into NTP at Maryland,
               and into the ISIS system at Cornell.  Sun RPC has been
               modified to use multicasting.

Internet Monthly Report                                        June 1989
 
 
            *  There is serious interest within the OSPFIGP WG of IETF
               on incorporating multicast routing.  This appears to be a
               natural extension, although it is too large an addition
               to be included in the initial OSPFIGP version.
 
            One problem with using IP multicasting at present is the
            general scarcity of multicast-capable interface hardware.
            We hope that the vendors will soon recognize this need and
            fill it.
 
            The group began discussion of plans for performing a major
            demonstration of multicasting, perhaps using the upcoming
            Defense Research Internet lines for a national testbed.
            Suggested applications include an interactive game (e.g.,
            Mazewar), teleconferencing, and the multicast distribution
            of data (e.g., netnews).
 
        Finally, Scott Shenker of Xerox PARC and Lixia Zhang of MIT have
        joined the task force.

     INTERNET ARCHITECTURE
 
        The Workshop on the Future of the Internet System Architecture
        and TCP/IP Protocols was held 1-2 June 1989 at the University of
        Delaware. About 77 souls attended the workshop, which included a
        day of individual presentations and a day of panel discussions.
        The proceedings are now being edited for early publication in a
        special issue of the ACM Computer Communications Review.

        1. Two drafts documents are now being circulated by the Point-
        Point Protocol Working Group.  One is a white paper on
        requirements.  The second is the preliminary protocol
        specification.  See 3. below for information on obtaining
        copies.
 
        2. The IETF will meet at Stanford University on July 25-28,
        1989.  Eighteen Working Groups are scheduled to meet.  Send to
        ietf-request@venera.isi.edu for a copy of the preliminary
        agenda.

        Following a suggestion at the April IETF meeting, another
        refinement was suggested to the agenda format to give even more
        time for Working Groups activity.  The suggested schedule was:
 
             Days 1 and 2
                9 am - 12  WG Morning session
                1 pm - 4pm WG Afternoon session
                4 pm - 5:30 Technical Presentations (in Plenary)
 
             Day 3
                9 am - 12 WG Morning session
                1 pm - 5:30 pm Technical Presentations (in Plenary)
 
             Day 4
                9 am - 12 WG Reports
 
        This gives an additional period for WG sessions, making a total
        of five session, but retains the overall time available for
        technical Plenary presentations.  This goal is to reduce the
        number of overlapping WG meetings.  This format will be tried as
        an experiment at the next several meetings.
        3. The "IETF:" and the "INTERNET-DRAFTS:" directories at the
        SRI-NIC.ARPA contain information about IETF activities,
        available by anonymous FTP.  These directories have been
        reorganized and brought up-to-date.
 
        The "IETF:" directory contains:
 
             - a general description of the IETF (history, organization)
             - a summary of active Working Groups within the IETF
             - IETF meeting dates/locations
             - upcoming meeting information
             - the upcoming meeting agenda, and
             - README file with an overview of directory contents.
 
        In addition, the directory contains the charters, status updates
        and current meeting reports for each Working Group.  These WG
        files are named in the following fashion:
 
             <WG NAME>.charter
             <WG NAME>.status
             <WGNAME>.report
 
        This Working Group information corresponds to the information
        from the most recent IETF Proceedings.
 
        The "INTERNET-DRAFTS:" directory contains draft documents that
        will be submitted ultimately to the RFC Editor to be considered

     PRIVACY
 
        During June, three RFCs were revised in preparation for release
        during July.  The revisions were required because of differences
        in X.400 and X.500 naming conventions and because of changes to
        the X.509 spec which resulted from suggestions put forth by this
        task force.  The RFCs undergoing revision are : Privacy

     SATNET
 
     Last month, we reported the retirement of the SATNET and its
     planned replacement by two point-to-point links from Europe to the
     US.  In January, the UK to US link was installed.  As of the end of
     June, Contel and Italcable were checking out the final piece of the
     point-to-point link from CNUCE (Italy) to DARPA (US).  The tail
     circuits at each end have passed testing and only the international
     satellite circuit remains.  As soon as the entire circuit is
     available, the gateways at each end will be connected up and final
     systems integration and test will be done.  In the meantime, CNUCE
     can be reached via BITNET and the VAN Gateway at BBN.
 
     TERRESTRIAL WIDEBAND NETWORK
 
     During June, we installed WPSs at SRI and New York and transitioned
     the gateways at SRI to the new network.  Work is underway to
     connect the RADC gateway to the NY WPS.  We also installed a
     gateway at NRL and connected it to the Washington WPS.  Over the
     summer, we will be continuing to install Wideband Packet Switches
     (WPSs) as power at the POPs and tail circuits between the backbone
     and the gateways become available.
 
     Throughout the month, the network continued to behave well with
     minimal software or hardware problems.  A line-error problem
     appeared at the end of June between NY and BBN.  This is currently
     being worked on and is expected to be corrected by the replacement
     of a bad CSU at the NY POP.

     as soon as the tail circuit is available.  We do not yet have a
     confirmed date for the on-site wiring but the current estimate is
     for some time in August.
 
     CMU (Pittsburgh WPS) -- Negotiations concerning on campus wiring
     are proceeding, but we do not yet have a confirmed date.  POP
     equipment installation and wiring will be scheduled once the CMU
     circuit is available.
 
     NCSA (Chicago WPS) -- A T1 circuit from the Chicago POP to NCSA,
     Urbana was ordered 6/13.  Circuit and Chicago POP facility upgrade
     are expected to be available in July.  WPS and gateway installation
     plans will be finalized as soon as there is a confirmed date for
     the circuit.
 
     TERRESTRIAL WIDEBAND TELECONFERENCING SYSTEM
 
     The conversion from the satellite-based Wideband to the terrestrial
     network is complete. The system will be available for use in 2-site
     and 3-site conferences on July 10.
 
     INTERNET R&D
 
     The VAN Gateway is now running EGP with CNUCE over Telenet.
 
     We have seen a number of outages on the line between BBN and RSRE.
     We are looking to see if there any common failure patterns.  So far
     we have not seen any.  The latest outage occured when RSRE (the
     building, not the gateway) was struck by lightning.
 
     We finished an overview paper on the Open Routing work for
     "Connexions."  This paper discusses the major architectural
     decisions of the protocol and why those decisions were made.  It is
     a complement to the architecture paper which goes into greater
     depth on what we plan to do and less depth on why.

CERFNET
-------
 
     SITE OUTAGES:
 
     The California State University's Office of the Chancellor's SWRL
     Facility was temporarily down on June 14th.  The AGS cisco gateway
     box suffered a major malfunction.  (This is the AGS that was used
     in the CERFnet pilot.) The new MGS cisco box designated for the
     SWRL facility was shipped out immediately to replace the loss.
 
     CIRCUIT OUTAGES:
 
     On June 5th, the University of California, Los Angeles (UCLA) link
     to San Diego Supercomputer Center (SDSC) was down from 10:00 a.m.
     to 11:00 a.m..  This was due to fiber vendor at UCLA mistakenly
     running test on the CERFnet link and rendering it out of
     service.for this period of time. Traffic to NSFnet from Hughes,
     UCLA and Los Nettos were consequently effected.
 
     On June 20th, Caltech reported a circuit outage.  Apparently the
     ethernet used between Caltech CERFnet cisco Box and their ethernet,
     was disconnected from the cisco box for an indefinite period of
     time. However, they did not lose any connectivity because the Los
     Nettos cisco box which is connected via a different ethernet was
     able to route the CERFnet traffic.
 
     Also, on June 19th and 20th, a major outage occurred on CERFnet.
     The PSN (the ARPAnet connection at SDSC) went down on the 19th at
     approximately 18:00 hours.  The link was down until 14:14 hours on
     June 20th.  Our PSN is used to advertise Net 10.0.0.0 which is the
     default network in the ciscos used for CERFnet.  When Net 10
     announcements disappeared the cisco boxes did not know where to
     route packets because many sites were unknown.  The reason for this
     outage is attributed to both ends of the SDSC PSN link to ISI and
     UCLA going down.
 
     OTHER NETWORK ACTIVITY:
 
     The installation of the CERFnet Backbone was completed in June. The
     University of California, Irvine (UCI) was installed on June 1st.
     Susie Arnold of CERFnet commented about the installation, "Because
     UCI is hooked to SDSC through a connection involving a 3-Com Bridge
     Box, there were some circular routing paths running for awhile."
     This bridge box has since been removed from the loop.
 
     UCLA, followed UCI and was brought on-line June 7th. The
     installation went smoothly. Again initially, routing issues

Internet Monthly Report                                        June 1989
 
 
     presented the only minor problem and were quickly solved.  However,
     once the link was in use other routing problems arose.
 
     Routing between CERFnet and Los Nettos (at UCLA and Caltech) was
     affected.  Several routing loops were discovered running between
     CERFnet, Los Nettos, and outside networks, such as NSFnet.  These
     needed to be evaluated and eliminated accordingly to ensure
     efficient routing of all traffic. Walt Prue of Los Nettos and Susie
     Arnold of CERFnet, continued to work on routing at UCLA and Caltech
     between the two networks throughout June.  During this process,
     Caltech suffered some difficulties when both of its cisco's, moon-
     doggie and cisco-kid, routed to each other, apparently each
     believing that the other was the best route for reaching UCLA.
     These problems have since been resolved and routing between the two
     networks is functioning well.  Cooperation between Los Nettos and
     CERFnet continues to be advantageous.
 
     The CERFnet circuit between cisco routers at UCLA and SDSC has been
     upgraded from 56 kbps and is now operating at 512 kbps.  UCOP
     recently conducted emergency testing and problem isolation work on
     the IDNX node sites running T1 at UCLA, UCOP,  and UCSB on June
     21st between 6:00 and 7:00 hours.  (This was necessary because of
     recent upgrades to T1 circuits.)  The UCOP IDNX was restarted,
     causing a short outage of all circuits between northern and
     southern campuses, and circuits at UC Berkeley and UC Davis.
     However, southern campuses were not effected.
 
     Some additional testing was required because the T1 between UCLA
     and UCSB continued to experience excessive errors UCOP scheduled
     testing late on June 22nd.  This testing effected all traffic to
     UCSB, however circuits to other campuses were not effected.
 
     The line from SDSC to UCLA was moved at both ends to the correct
     cisco box at UCLA and SDSC.  Routing to UCLA is following the same
     path that it did previous to the switch.  The preferred route is
     via the T1 link to Caltech, across the Ethernet to the Los Nettos
     cisco box, across the T1 link to the UCLA Los Nettos cisco box.
 
     UCSB was to be brought on-line on June 23rd but the V.35 cable
     which connects the IDNX to the cisco box wasn't correct.  The cable
     problem is being resolved and a new installation date for UCSB is
     pending the arrival of the correct cable.
 
     The CERFnet newsletter was distributed to over 200 recipients.

     "National High-Preformance Computer Technology Act of 1989".  We
     collected timing data for actual transfers of images across the

     incorporated this data into the demo program they prepared to
     display still images and "movies" at these different speeds.
 
     Development of an integrated conferencing environment continues.
     File distribution modes optimized for conferencing scenarios were
     added to MBFTPTOOL.  Refinements were made to the packet video
     host's operator interface and its coordination with the packet
     voice host in our efforts to make the system more operational and
     robust.

     There was much discussion about how to make routing work when a
     planned north-south line between Los Nettos/CERFnet and BARRnet is
     brought up.  The routing is made complicated by the fact that the
     Arpanet and the NSFNet are connected to both regionals already.
     Additionally CSUnet and the U.C.DLA-Net are both connected to both
     regionals but do not wish to be transit networks.
 
     SNMP was brought up on several nodes of the network.  We are using
     the MIT development kit.  We have found SNMP useful for debugging
     routing problems and for obtaining traffic statistics
     programmatically.

     Expansion Proposal Approved
 
     In June, the National Science Foundation approved $6 million in
     funding for Merit's NSFNET expansion proposal to add nodes to the
     NSFNET backbone.  This approval raises the total amount authorized
     for the five-year project to $20 million.  In the near future, the
     NSF will solicit proposals from organizationswishing to become
     nodes on NSFNET.  The NSF, in consultation with Merit, will then
     choose the new node sites by October or November of this year with
     implementation following, probably early in 1990.

     NSFNET Reconfiguration update
 
     Phase A of the NSFNET reconfiguration has been completed and
     production trafficis running at T1 rates with redundancy at all
     nodes.  The move to a more robust network is nearing completion.
 
     Interagency Connections
 
     Within the past six months efforts have been underway to design
     closer interconnection points between agency peer networks in order
     to rationalize routing and improve the manageability of those
     connections.  Two major points of interconnection between the
     NSFNET, the ARPANET/MILNET, and the NASA ScienceNetwork were
     proposed and authorized as the first phase of this process.  On the
     west coast the NSN connection at Ames via the Split-E-PSP
     connection to Palo Alto became operational on June 22.  On the east
     coast the NSN connection to the NSFNET at College Park was
     implemented on June 15.  Support from Milo Medin and Tony
     Villasenor of NASA, Bill Yundt of BARRNet and Jack Hahn of SURAnet
     was critical to this endeavor.  The phaseover of networks from old
     to new gateways will continue throughout July.
 
     These changes represent significant progress architecturally as
     well as from the perspective of managing peer network
     interconnections, with implications for security and policy- based
     routing.  The direct peer-to-peer interaction represents a
     transition in technology to establish EGP sessions with the
     mailbridges providing access to the ARPANET and MILNET.  With the
     implementation of a split E- PSP, EGP peers do not need to be co-
     located with an NSS (Nodal Switching Subsystem).  Changes in
     "routed" to support the new configuration were made in cooperation
     with IBM.
 
     Comparison of Traffic Counts
 
     Traffic on the NSFNET continues to increase with June packet counts

     A 56K link to LANL, via cisco's, has been put into operation.
     Currently only traffic between LANL, SDSC, and UCSD is being

     The PSN (26) at SDSC will be removed during July.  To that end, we
     have routed traffic that was aimed at it to ISI's PSN via CERFnet
     and Los Nettos.  We elected to do this now rather than retain a
     host link until the fall as our path is now all T1 (3 hops) vs the

     1. We have put up the Nottingham (J.Onions) Remote Operations version of
     the Network Time Protocol (NTP). This is peering over X.25 (JANET) with
     Nottingham, and with several US sites over the Internet. We will
     shortly be getting a Rugby Clock Receiver so that we can run a stratum
     one clock for the UK.

     1.   The Workshop on the Future of the Internet System Architecture
          and TCP/IP Protocols was held 1-2 June 1989 at the University
          of Delaware. Paul Schragger and Mike Davis spent some days
          transcribing and editing the workshop proceedings. Since this
          project produced rather more output than originally
          anticipated, work continues on further editing and preparation
          for publication.
 
     2.   Final touches are now being added on a detailed analysis and
          commentary of the Border Gateway Protocol (RFC1000). A plan
          for proposed experiments using resources of the Research
          Internet Backbone is nearing completion. The plan is based on
          relatively simple modifications to selected hosts and gateways
          which allow participation of research nets located far from
          the Backbone itself.
 
     3.   Mike Davis brought up the current version of SNMP, which now
          runs in assorted Suns and PCs. We are now watching our campus
          nets and selected SURA paths to the NSF backbone Point of
          Internet Presence (PIP, hereby introduced). Our system staff
          brought up traceroute, which immediately boggled minds
          demonstrating tortuous routes used by our clockworking
          friends.
 
     4.   The various Fuzzball time servers scattered throughout the
          Internet are logging increasing numbers of ICMP messages in
          patterns which suggest occasional massive routing loops

          lasting in the order of a half hour. Most of these appear to
          involve contorted ARPANET/NSFNET paths and occasionally
          involve MILNET. Logging procedures have been modified to
          select additional related information for subsequent analysis.
 
     5.   New NTP sites have come online in Australia, Hawaii and
          Norway. It is reported that Japan, New Zealand and Finland
          will shortly be next and soon the first WACC (Worked All
          Continents Clocks) certificate should be awarded. Following
          suggestions by several people, the NTP spec was amended to
          revise the authentication mechanisms and move the text to an
          appendix. Also, a new appendix on control messages was added.
          Finally, a precision oven-controlled crystal oscillator
          arrived and began begging for an interface it a handy Fuzzball
          time server.

     1.   Hewlett Packard in Fort Collins, Colorado (Westnet is
          secondary to BARRNET) and the Idaho National Energy Laboratory
          in Idaho Falls, Idaho became connected this month.
 
     2.   We expect Idaho State University in Pocatello, Idaho to become
          connected during the month of July.  This will result in a
          minor topological change in the circuits in Idaho.
 
     3.   We are investigating upgrading all of Westnet's interstate
          circuits to T-1 for next year, and add a redundant link to run
          between the University of Arizona in Tucson and New Mexico
          Technet in Albuquerque. There is a need for faster response
          time during interactive sessions, and for greater bandwidth
          for research applications.
