IAB TASK FORCE REPORTS
----------------------
 
  APPLICATIONS -- USER INTERFACE
 
     The task force met February 7-8 at SRI International.  Principal
     topics of discussion included telco futures, real-time
     teleconferencing (principally, BBN's latest version of MMConf and
     HP Lab's tV), and nation-wide inter-organizational multi-media
     testbeds.  Specifically:
 
     - It is widely believed that the regional Bell operating companies
     are hesitant to deploy ISDN, and would prefer to place their bets
     on B-ISDN.  Doing so would certainly reduce their long-term costs
     (one deployment versus two).  Some might suggest such a tactic
     would also let them avoid significant embarassment over the current
     state of ISDN (e.g., there is still no standard for placing calls
     outside an ISDN switch).  In the near term, however, significant
     opportunities for experimentation--with a widespread, medium-speed
     network--could be lost.
 
     - MMConf now offers much the same functionality as "shared window
     systems" in that it supports existing applications.  At the same
     time, facilities are provided that support the development of
     "conference aware" applications.  On the down side, MMConf still
     runs only under SunWindows and it suffers from all the well-known
     problems intrinsic to a replicated architecture.  However, given
     the potential performance benefits of the replicated architecture,
     BBN and Olivetti Research Center are continuing to plug away at
     those problems.
 
     - Lester Ludwig (Bellcore), with assistance of several task force
     members, has been promoting the creation of a wide-area broadband
     network for experimentation in multi-media communications and
     computer-supported cooperative work.  Each of the contributors to
     this effort believes it is critical to their own research program
     to evaluate their technologies in a wide-area, inter-organizational
     setting.  Since no single participant is currently capable of
     putting together such a network, the proposed testbed is itself a
     collaborative venture.  The proposal has already attracted
     significant attention, including endorsement "in spirit" by the
     National Science Foundation.  It is currently under review by the
     Corporation for National Research Initiatives for consideration
     under their research program in high-speed networking.  The Task
     Force has recently formed a working group, chaired by Lester
     Ludwig, to coordinate further development of such a testbed.
     Further details will be provided in the next Monthly Report.

Internet Monthly Report                                       April 1989
 
 
     - A working group on "connection architecture" has also been
     formed, chaired by Dan Swinehart (Xerox PARC).  Its purpose is "to
     define an architecture that captures, at a sufficiently high level,
     the notions of voice [and video] connections and of the services
     that use them."  Further details will be provided in the next
     Monthly Report.
 
     Other selected items of interest:
 
     - Xerox currently has a software implementation of a DES-like
     encryption algorithm running at 8 Mbits/sec on a Sun-4.  It
     includes a 1-way hash to cope with viral infections, etc.
 
     - The NeWS Development Environment (NDE) is supposed to be included
     in the System V Release 4 distribution.
 
     - The newly-formed Entry Systems Division of Sun intends to
     emphasize wide-area networking.
 
     - Chris Schmandt (MIT Media Lab) is researching the use of speech
     synthesis and recognition as the interface to window managers, as
     well as "object-oriented cut and paste" (e.g., pasting an e-mail
     message into a rolodex tool should result in the computer placing a
     phone call to the sender of the message).
 
     The next meeting of the full task force will take place June 13-15
     at Bellcore, Red Bank, NJ.
 
     AUDIO SERVER WORKING GROUP
 
     The Audio Server Working Group held a teleconference on March 22
     between SRI and BBN.  After much debate, it was decided to adopt
     the new Natural Micro Systems VBX voice board for the next version
     of VOX.  A copy of said board has subsequently arrived at Olivetti
     Research Center (ORC) and work is underway to integrate it into the
     VOX environment.  This selection does not, however, preclude the
     use of other voice boards in the future; indeed, there was general
     agreement that multiple boards must be supported in the long term.
 
     The ORC implementation of VOX is moving to the Mach operating
     system platform.  Eventually, ORC intends to take advantage of
     Mach-specific features, including IPC and threads.  However, in the
     short term none of the these features will be used, such that VOX
     will run in a standard BSD 4.3 system.  This will expedite
     collaboration with other organizations, including Sun and MIT.  As
     ORC migrates to using Mach-specific features every attempt will be
     made to provide a "bi-lingual" interface such that VOX continue to
     support BSD clients.

     Finally, efforts continue to make VOX available with as few
     restrictions as possible.  The current tack is to create a VOX
     Consortium along the lines of the MIT X Consortium.

        1)   The IETF met April 11-14, 1989 at Cocoa Beach Florida.  The
             meeting was hosted by Kennedy Space Center.  The 3.5 day
             meeting followed the new format of Working Group (WG)
             meetings on the first two days, technical briefings on the
             third day, and WG reports on the concluding half day.
             Sixteen Working Groups met and reported.  The preliminary

     INTERNET MANAGEMENT
 
        As chairman of the Internet Management Task Force, I presented
        an IAB recommendation to the DoD Protocol Standards Steering
        Group.  It was recommended that a memorandum from the PSSG or
        from the Director, DCA, be sent to all DoD procurement
        authorities stating that references to the TCP/IP MIL-STDs be
        accompanied by references to matching RFCs. One way to do this
        is by referencing or copying the OFFICIAL PROTOCOL LIST RFC
        (i.e., 1100). The PSSG has confirmed it will prepare such a
        memorandum.
 
        Along with Dave Mills, I will represent the IAB at a RARE
        (European Association of Research Networks) meeting in Trieste,
        Italy, May 8-10. I will present an overview of the IAB and its
        Task Forces. An article on this subject will appear in a later
        issue of Computer Networks and ISDN.

     PRIVACY
 
        The activities this month included continued work on the RFC for
        Privacy Enhancement for Internet Electronic Mail: Part II
        Certificate-Based Key Management and RFC 1040, Privacy
        Enhancement for Internet Electronic Mail: Part I: Message
        Encipherment and Authentication Procedures.  These will be
        distributed shortly.
 
        A one-day workshop to discuss standards for a "commercial
        version" of the IP Security Option (IPSO) will be held on
        October 6, in conjunction with Interop '89 in Santa Clara.
        Participation in the workshop is on an invitation only basis, in
        order to ensure that the participants will all be contributors
        to the process, not just interested attendees.  All participants
        are preparing a brief presentation and an accompanying position
        paper expressing their thoughts on what an IPSO for the
        commercial environment should encompass.  Presentations will
        address topics such as requirements, functionality, processing

     WIDEBAND NETWORK
 
     April saw a great deal of activity associated with the
     reconfiguration of the Wideband Network from a satellite-based to a
     terrestrial fiber-based transmission medium.  The transition effort
     is described elsewhere in this report.
 
     Throughout the month the six remaining Wideband Satellite Network
     nodes (ISI, Lincoln Laboratory, DCEC, SRI, RADC, and BBN) continued
     to exhibit stable behavior and continued to support multimedia
     conferences and ARPANET long-haul inter-PSN connectivity.  Both of
     these current Wideband applications will be moved to National
     Network Testbed (NNT) terrestrial fiber facilities, and access to
     the Wideband satellite channel will be terminated, in the near
     future.

     TERRESTRIAL WIDEBAND NETWORK
 
     This month, we began the transition of the Wideband Network to
     terrestrial links.  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.  After
     having previously burned in the software and hardware in a testbed,
     we are currently going through shaking down the systems for any
     problems that might only show up in the real network.
 
     The first two WPSs were installed at BBN and the Washington POP.
     Later, a third WPS was connected at the LA POP.  The IP gateways at
     BBN, DARPA and ISI were switched to the new network as soon as each
     local WPS was in place.  The ST gateways at these sites were not
     switched over until all the local WPSs were installed.  This was so
     that we could move the three ST gateways at the same time and thus
     minimize disruption of ongoing conferencing work.  At this point,
     the only ST gateway left on the satellite-based Wideband is at SRI.
 
     A successful demo of the terrestrial Wideband was held at DARPA on
     4/20.  BBN demonstrated the effect of the higher throughput of the
     new network on the performance of SLATE (multimedia communications
     software). This was done by comparing the performance of some new
     conferencing tools over the terrestrial Wideband between DARPA and
     BBN and over the ARPANET between DARPA and RADC.
 
     Future installation work will include:
 
     RADC, Ft. Monmouth (NY WPS) -- Next month, we plan to install a WPS
     at the NY POP and transition the Wideband gateway at RADC to the
     new network.  The site at Ft. Monmouth will be connected to this
     WPS as soon as the tail circuit is available.  We have been told
     that the on-site wiring could take approximately 60-90 days.
 
     SRI, Stanford (SRI WPS) -- Until the ARPANET IST trunks are moved
     off of the Wideband to the new T500 backbone (or until the Wideband
     satellite channel is turned off), the ISI and SRI BSATs will not be
     freed up for use as the SRI and CMU WPSs in the new network.  For
     use as WPSs, both machines will need to be upgraded and cabled to
     CSU/DSU equipment, fail safe box, etc.  As soon as the BSAT
     hardware becomes available, we will do the installation work to
     connect SRI (WPS, IP and ST gateways) and Stanford (IP gateway) to
     the new network.
 
     CMU (Pittsburgh WPS) -- We have been informed that work on power
     and wiring at the POP was begun on 4/28.  We will have to wait for
     the SRI/ISI BSAT hardware in order to build a WPS for the
     Pittsburgh POP.  On campus wiring for CMU is scheduled for early

     Statistics collected by ISI showed an average of 99+% uptime for
     the remaining SIMPs -- Fucino, Italy and Roaring Creek, USA.  There
     were a couple of outages of the CNUCE gateway.  In both cases,
     before we were able to reach the site contacts, the gateway came
     back up.
 
     Our most recent information indicates that the Italian half of the
     point-to-point link between CNUCE, Italy and DARPA, U.S. should be
     installed in mid-May.  We expect the US half of the link to be
     ready before this.  Once the point-to-point link is in place, the
     DARPA and CNUCE gateways will be switched from the SATNET to the
     new link.  As soon as end to end testing is done and the overall
     path is operational, the SIMPs will be retired.

     INTERNET R&D
 
     The Butterfly version of the VAN Gateway was installed.  We are
     currently doing beta testing with the VAN users.  We also wrote a
     note that was distributed to the ICB on recommendations for using
     the VAN gateway as a backup path in the event of other
     communication failures.
 
     We are preparing to ship and install three Butterfly Gateways for
     SURAN sites.  These will be installed at SRI (1) and Ft. Monmouth
     (2) in late May / early June.
 
     We installed new gateway software (Release 4.1) in the gateways
     (ARPA-WB, ISI-WB, BBN-WB) associated with the new Terrestrial
     Wideband Network and that were used in the demo on 4/20.  Over the
     next month or so we will be updating the software in the other
     Wideband sites as they transition to the new network.

CERFNET
-------
 
     Over the past month there has been a great deal of activity as
     CERFnet embarks upon it's turn-up period. New links were initiated
     and various meetings and conferences were attended by the CERFnet
     staff. In addition, plans were initiated for two CERFnet sponsored
     seminars, one on Simple Network Management Protocol (SNMP) and the
     other on network security, tentatively scheduled to be held this
     summer.
 
     The installation of the CERFnet backbone has been rescheduled for
     the first week of May. The University of California at Irvine, part
     of that backbone, will be one of the first sites to be brought up.
     The California Institute of Technology (Caltech), also a backbone
     site, will be brought up the following week. Shortly thereafter,
     the University of California at Los Angeles will follow as the last
     of the backbone sites to be brought up. Installations for the
     remaining sites will commence the last week of May, assuming all
     goes well with the installation of the backbone.
 
     On April 11th, Los Nettos to CERFnet routing was implemented via
     the University of California at Los Angeles (UCLA)-SDSC 56 kilobit
     link. During this process, the SDSC cisco box had to be rebooted
     due to configuration problems.  Restrictions in the cisco software
     prevented the box from being configured in the desired manner and
     this resulted in the box having to be rebooted.
 
     Los Nettos has agreed to loan CERFnet a port on the California
     Institute of Technology (Caltech) Los Nettos cisco gateway. The
     port was used to turn-up a connection to Hughes Aircraft Company on
     April 27. Hughes' ARPAnet connection was scheduled to be
     disconnected on May 1. In addition, cisco Systems is providing a
     loaner gateway to be used at the Hughes end of the link until the
     CERFnet hardware is delivered in May.
 
     The Research Institute of Scripps Clinic has decided to accept an
     Associate Membership with CERFnet in lieu of their proposed Regular
     Membership. Scripps intends to use their SDSC provided
     telecommunications equipment to access CERFnet and will upgrade
     those facilities to T1 in the near future.
 
     The Claremont Colleges; Pomona, Harvey Mudd, Pitzer, and Claremont
     Men's, will be provided with a 56 kilobit CERFnet link to Caltech.
     They are tentatively scheduled to be brought on line during August,
     1989. We look forward to the participation of the Claremont
     Colleges.

CICNET
-------
 
     CICNet has been fully operational since March 3, 1989 and has
     experienced no major outages.  Currently, Merit is testing the
     options for running DECnet traffic over CICNet.  The major
     advantage of providing DECnet capabilities is that DECnet schools
     can make use of the T1 bandwidth of CICNet to exchange information.
     Merit is in the first phase of testing these capabilities.  DECnet
     has been enabled to run concurrently with IP on the cisco routers
     located at the University of Michigan and Michigan State
     University.  This testing is intended to ensure that DECnet routing
     information is being exchanged properly between routers and to
     assess the impact of DECnet on router performance.  In the next
     phase of testing, DECnet traffic will be routed from a MicroVAX
     located at the University of Michigan (not yet in place) to a VAX
     at Michigan State University.  Once these machines are in place,
     Merit can determine if DECnet traffic significantly impacts the
     performance of the already operational IP network.
 
     Now that implementation is complete, CICNet is concentrating on
     building an active user support organization.  Each CICNet campus
     has technical and network information support services.  Merit is
     contracted to provide support services to these campus resources.
     Operations support is provided by the Merit Network Operations
     Center (NOC).  Cathy Aronson, of Merit Internet Engineering, will
     provide technical support to campus sites.  As of May 1, Dana
     Sitzler, of Merit Information Services, will provide network
     information support.  Meetings are planned for May and June to
     address technical and information support issues.

     INTERNET CONCEPTS PROJECT
 
     A plan for evaluating the IP/SQ congestion control scheme was
     decided.  This involves producing a modified Unix IP in a select
     group of SUN workstations resident on an ISI LAN.  After that,
     local gateways will be altered to produce Source Quench messages
     whenever a gateway queue overflow occurs.  Subsequently, a series
     of data transfer tests will be run from the modified SUNs, through
     the altered gateways to receiving hosts.  Statistics will be
     gathered and the results compared with simulation data to determine
     whether or not the congestion control algorithm works as well in
     vivo as in simulation.  The first portion of this plan, to produce
     a modified SUN kernel, is now being undertaken.

     MULTIMEDIA CONFERENCING PROJECT
 
     We have made the transition from satellite to terrestrial Wideband
     Net, and we aren't looking back.  Packet voice and video have been
     transmitted over the new net, but teleconferencing service is not
     available yet because there is still some shakedown to complete.
 
     Before the transition, we brought up packet video connections
     between the ISI and DARPA sites using Widcom codecs.  Since the
     Widcom is less tolerant of lost data than the Image30 codec, the
     packet order-restoration algorithm in the Packet Video Host (PVP)
     had to be enhanced to handle ST packets four packet positions late.
     and sometimes six positions late.  This algorithm was also made
     more robust to tolerate arrival of duplicate packets that were
     produced by a now-fixed bug in the terrestrial Wideband Net.  So
     far we have tested the Image30 codec over the new net; next we will
     test with Widcoms and possibly other new codecs.
 
     The multimedia conferencing control software (MMCC) continues its
     migration from SunView to the Diamond Toolkit.  This month, MMCC's
     video control functions were converted to run under the toolkit.
 
     Annette DeSchon continued work on a Multiple-host Background File

JVNCNET, NORTH EAST RESEARCH REGIONAL NETWORK
---------------------------------------------
 
     The major events of the month can be summarized as (i) record
     traffic volume, (ii) JvNCnet Phase II starts to provide service,
     (iv) International Connections, (vi) new JvNCnet members welcomed.
 
     The overall up-time for the network this month was 98.12% (higher
     than last month).
 
     The "estimated" amount of traffic in and out of the JvNCnet system
     for this month was 1,093,752,716 packets.  This traffic is a very
     significant increase from last month (947,074,662 packets).  The
     traffic coming from the NSFnet was approximately 26.44% (a
     percentage decrease from last month), the traffic coming from the
     ARPANET amounted to approximately 7.54% (similar percentage than
     last month), the traffic from NORDUnet was 2.07% (a similar
     percentage than last month), traffic from JANET amounted to 0.72%
     of the total traffic.  The traffic on the JvNCnet Regional Network
     this month corresponded to 63.23% of the total traffic (larger than
     last month).
 
     The JvNCnet II network backbone node in Newark, NJ, and its
     connections to Rutgers U., NJIT, Stevens Institute of Technology
     and the University of Medicine and Dentistry of New Jersey has been
     performing well.  All the routers for the backbone nodes in:
     Boston, Philadelphia, Trenton, New York City, Stamford and
     Providence arrived and are undergoing testing before being deployed
     in the field.
 
     The connection to the Joint Academic Network (JANET), is fully
     operational since the 25th of April.
 
     Bell Laboratories, and Bell Core have been connected to the JvNCnet
     network.  Both sites are connected "temporarily" at 56kbps to a
     JvNCnet gateway in Columbia until their T-1 circuits into the
     Newark JvNC-BNS are operational (some time in June).
 
     The JvNC Network Operations Center (JvNCNet NOC) provides support
     to the JvNCnet network as well as the internal network of the JvNC.
     The NOC is staffed from 9am to 5pm Monday through Friday.  The
     Computer Operations staff monitor and perform minor trouble
     shooting tasks between 5 p.m. and 9 a.m.  and are the backup for
     the Network Operations Center.  Network Staff are on call after
     hours and during weekends and holidays.  The JvNC Network
     Information Services Center is now staffed, and provides support
     from 9am to 5pm Mondays to Fridays.

LOS NETTOS
----------
 
     CERFnet brought up a 56K link from UCLA to SDSC.  This gave Los
     Nettos NSFNet access.  We are using this path as the perfered path
     for all of the NSFNet advertised networks.  This came up at a time
     when we were having problems with our BBN gateway access.  It
     considerably helped resolve a lot of our routing problems at a most
     opportune time.
 
     Because of the new path for much of our member's traffic we have
     new routing configuration changes to make.  We need to make the
     routing decision to use NSFNet when it says it can get to the
     destination otherwise use the Arpanet who also advertises the same
     routes plus many more.
 
     We have received 10 Datatel 3552 units in the last couple of
     months.  Of those, four were D.O.A. unable to successfully pass
     data at 1.536 Mb/s in a loop configuration. Three others had
     console port problems.  Datatel appears to have a quality control
     problem!
 
     Hughes, a CERFnet member, was attached to a spare Los Nettos port

     presented partial results of our simulation tests on the
     effectiveness of random drop as a congestion avoidance/control
     mechanism.  The results show that random drop does not prevent
     misbehaving connections from taking an unfair share of network
     resources.  More research and simulation tests are now being
     conducted on various fair queueing algorithms and random drop
     strategies, to further identify their effectiveness and

     are now coding the libraries that will extend our instrumentation
     to OSI.  Some experiments will take place entirely in our
     artificial Internet.  Others have involved a few last measurements
     using ARPANET paths.  MITRE will be the site of an NSFNET-MILNET
     mailbridge, and as part of this, the testbed connectivity to NSFNET
     will be added to our measurement capabilities.

MRNET
-----
 
     MRNet continues to provide Internet service to the domestic, albeit
     somewhat smaller, supercomputer industry; the closing of ETA
     Systems was the major focus of MRNet this month.
 
     Several key MRNet volunteers were adversely affected by the events
     at CDC and ETA.  MRNet hopes they will find employment in the area
     and continue their contributions to MRNet.
 
     ETA's MRNet connection was severed somewhat abruptly. This caused
     router and mail confusion for several days.  Bethel College, which
     was receiving mail through ETA, is still without Internet mail
     service. Some ETA employees can again receive mail at ETA, though
     this is expected to last only a limited time.  CDC may be
     disconnected from MRNet for a few weeks in the near future while
     their MRNet connection is moved within CDC.  The CDC division which
     provides MRNet service to CDC was eliminated.  Nonetheless, CDC is
     still very interested in remaining an MRNet member.
 
     Some progress has been made by the business plan, membership, and,
     bylaws committees.  More progress is required and is planed to be
     made prior to the MRNet June meeting.

     At its February meeting, the NWnet Technical Committee recommended
     that we reengineer our network to reduce maximum delay times by
     moving from the current mostly-ring to a mostly-tree topology.  We
     instructed our network manager, Boeing Computer Services, to
     provide cost data for the change, and based on the cost data they
     provided voted to go ahead with the change at our April meeting.
     However, BCS has since that time concluded that their network
     operations staff is not competent to manage a non-redundant
     network, and hence that the labor cost of such a design would be
     very high as their engineering staff became involved in routine
     operations.  We are currently negotiating with them to determine if
     a reasonable compromise design is possible and desirable.

     Development of Network Planning Tools
 
     Since becoming operational in July 1988, traffic in the NSFNET
     backbone has more than tripled.  In the ongoing planning for future

     growth, Merit/NSFNET continues to develop tools for observing
     traffic patterns and usage in order to predict future needs and
     "tune" the network accordingly.  One of the tools under development
     will produce criteria for configuring the network based on
     historical and current real-time network data.  Some of the input
     for this tool includes data on traffic patterns, packet length
     distributions, and link costs. The output will consist of
     peak/average link utilization, load/delay trends, and optimum
     topologies along with current and predicted network performance.
     Ultimately, repeated iterations of this process will yield a set of
     information from which network parameters can be derived.  These
     criteria will then provide a rationale for timely network
     adjustments using the Digital Reconfiguration Service (DRS is a
     product of MCI) and will also be used in planning for the future of
     NSFNET.
 
      Comparison of Traffic Counts

     While packet counts continue to grow, network traffic has leveled
     off slightly after the dramatic increases of the past two months
     (30% in March and 23% in February).  Network connections also
     continue to increase and, as of 4/30/89, stand at:

     PSC is now providing primary NSFnet to ARPAnet connectivity via
     psc-gw4.  It carries all of the traffic between NSF only networks
     and ARPA only networks.  Psc-gw4 and its 56k link to PSN14 have
     been very stable and are relatively unstressed.  The number of VC's
     in use has been dropping steadily over the past month.
 
     However our connection to the ARPAnet, PSN14, is still seriously
     congested.  Psc-gw4 discards 15-20% of the traffic presented from
     the NSFnet because PSN14 refuses the traffic.  This is the long
     term average: During prime time it often discards more than it
     delivers.  PSN14 has also had some congestion related down time.
 
     Below is a summary of the routing table from psc-gw4.  These are
     the best known routes to the all of the networks connected to the
     national internet.  Since the data was collected from dynamic
     routing protocols it reflects the actual state of the internet,
     including outages, rather than the designed quiescent state.  Note
     that MILnet contributes almost half of remaining ARPA networks.
     The top two of the remaining gateways contribute the next quarter.
 
     Total NSF nets:  423 (Including 12 PSC nets)
     Total nets via Mailbridges (Milnet nets): 159

     The NNSC ran a 2-1/2 day conference on Wide-Area Networking for
     members of NSF's Long Term Ecological Research project, part of the
     Directorate of Biological, Behavioral and Social Sciences.  The
     workshop, which combined lectures and lab sessions, was sponsored
     by NSF and hosted by the National Center for Supercomputing
     Applications at UIUC.  Speakers covered general networking topics
     as well as resources available to researchers on the Internet.
 
     Craig Partridge gave a presentation at the Internetworking Seminar
     run by Merit and Karen Roubicek attended National NET'89 and IETF.

     RFC 987 (1988):  Steve Kille has written an upgrade of RFC 987 to
     use the X.400(1988) / ISO/IEC 10021 (MOTIS).  This specifies a
     mapping between X.400 and RFC 822 over a number of common RFC 822
     based message transport protocols (including SMTP).  The forum for
     discussion is ifip-gtwy@tis.llnl.gov.  It is intended that this
     document will become an RFC in about two months time.
 
     We are investigating the representation of Domain Name Scheme and
     associated information in the OSI Directory (X.500).  It is

     proposed to make some small experiments with this.
 
     The QUIPU Directory system was distributed with ISODE 5.0.  This is
     believed to be the first implementation of the OSI Directory which
     supports both the Directory Access Protocol and Directory System
     Protocol.  It has been installed at a number of internet sites
     (including: NASA; Nysernet; The Wollongon Group; Columbia
     University), as well as in Europe.  An informal pilot is evolving,
     and participation is encouraged.

     1.   Our swamprunners continue hacking theses and various odd jobs.
          Jeff Simpson finished his Masters thesis on a formal model and
          grammar for a policy-based routing protocol. Mike Minnich has
          several chapters done of his Ph.D. dissertation on rate-
          controlled flow management. Paul Schragger built a rough-hewn
          simulator for our proposed gigabit network and obtained some
          preliminary results.  Dave Mills attended an IAB meeting at
          MCI in Washington, DC. Vint Cerf presented his thoughts on
          information infrastructure to an enthusiastic mob at a
          department colloquium.
 
     2.   Significant activity occured this month on our proposed wide-
          area TDMA gigabit network. Prof. Charlie Boncelet worked out a
          first-cut, collision-free scheduling algorithm. He came up
          with a cute idea where the scheduler can even divert a burst
          to an idle trunk to take advantage of a later unoccupied slot.
          We have secured fiber trunks between the laboratories of the
          principal investigators, as well as a couple of uVAXen that
          can be used as experiment platforms. We are investigating
          candidates for the transceiver and crossbar components.
 
     3.   Effort continued on testing the new NTP Version 2 beta
          implementations for Fuzzball and Unix systems. Louie Mamakos
          at U Maryland updated the beta release several times. Dennis
          Fergusen at U Toronto made major improvements in the code, as
          well as added support for authentication and an interface to
          the Precision Standard Time WWV receiver. Most of the eleven
          Fuzzball primary time servers now have between fifty and
          ninety regular secondary peers.
