              NOTES ON THE NETWORK WORKING GROUP MEETING

Wednesday Evening, February 17

   Mike Sher opened by welcoming the group to Urbana and briefly

   indicated that ILLIAC IV was expected to be running this summer.  The

   ILLIAC IV Project has been split into two projects; one on basic

   system hardware and software, and the other on applications.  Their

   IMP is not yet connected to their PDP-11.

   Steve Crocker asked for topics to be discussed at this meeting; these

   are indicated below.

   Peggy Karp of Mitre has been summarizing the old RFC's.  She has a

   list of about 30 topics and is summarizing their present status.  She

   expects to finish around the end of February.  See RFC #100,

   NIC(5761).  It was suggested that someone write an RFC indicating

   which ones are obsolete.  It was also suggested that the Network

   Information Center (NIC) help sites in organizing their hardcopy

   material.

   There then followed brief discussions of experiences in using the

   Network.  John Melvin (SRI-ARC) summarized SRI's experience in using

   the Utah PDP-10 to help in SRI's transfer from an XDS 940 to a PDP-

   10.  In April-May 1970 it was clear that SRI was headed toward a

   PDP-10 in order to have the capacity and reliability to fulfill their

   role as the Network Information Center.  They had had some previous

   experience in connecting with Utah, and so it seemed logical to try

   to use the Utah 10 to aid the transfer.

      In June use of the Network began.  SRI uses higher level languages

      extensively, so the first task was to transfer the compiler-

      compiler Tree Meta.  Source code was generated on the 940 to run

      on the PDP-10.  Binaries were then transmitted to Utah and run and

      debugged.  Patches were performed where possible, and source

      changes accumulated.  A new source and binaries would then be made

      periodically.

RFC 101        NOTES ON THE NETWORK WORKING GROUP MEETING  February 1971

      Once Tree Meta was running, a new high level language (called L-

      10) for programming the On-Line System (NLS) was implemented in

      the same way.  When L-10 was running the core device independent

      parts of NLS were rewritten and debugged.  NLS was completely

      reorganized during the transfer.

      At the SRI and Utah ends a control program allowing three users to

      connect to Utah was written, which ran as a user process and

      allowed character interaction and files to be transmitted.  The

      scheme worked well and much useful work was accomplished in the

      July--December period with some people on 4-5 hours per day.  The

      voice link was used when something would go wrong in trying to

      determine where the problem existed and to reset.  At times they

      would go 2 weeks with no problems.  SRI has an IMP interface

      diagnostic which ran as a T/S process.

      Generally, echoing was handled at the SRI end.  DDT was used at

      Utah end.  Round trip character delays of 4 seconds were not

      uncommon, and at certain points delays of 8 or 10 minutes were

      experienced.  Thes...
