* September AIW minutes

  The third APPN Implementers Workshop was held at the Sheraton
  Imperial Hotel in Research Triangle Park, NC on September 28-30, 1993.
  40 companies were represented at the AIW with over 150 attendees.

  Gerry Williamson, Senior Systems Programmer for Provident Life and
  Accident Insurance Co., began the meeting with a presentation on
  Provident's experiences with APPN. He spoke about Provident's
  computing background and why they chose APPN, identified problems
  they have encountered, and provided tips for APPN network planning.

  Lee Rafalow presented an overview of the AIW Process and Technical
  Plan.  This meeting was conducted using the AIW procedures except
  for the provision about membership.  The membership provision will
  be used at the next AIW in February.  Requests for signature
  copies of the Membership Agreement should be sent to Lee Rafalow
  ([email-masked]).  The Technical Plan, as amended during
  the workshop, was granted AD status at the closing session.

  John Waclawsky presented 'A Performance and Stability Comparison
  of SNA and TCP/IP'. He described the differences between connection
  oriented and connectionless transports, examined window protocol
  and timer repercussions, and discussed the techniques of data
  encapsulation and protocol conversion.

  The Data Link Switching SIG met to review the status of the seven
  working groups. Four of the groups then held breakout meetings.
  Minutes for these meetings can be found in the DLSw mail exploder.
  The SIG expects to achieve AD status on all of the first 'release'
  issues at AIW 4 (Feb 94).

  Ed Tremblay presented an introduction to the DLUR architecture,
  Walt Smith presented an overview of the LAN Address Resolution
  architecture, and Dave Bryant held two sessions on APPN architecture
  updates. In addition to technical discussion on the architecture
  updates, the following items were discussed:

    - How to communicate architecture changes to external vendors
    - How to verify deviations have been corrected

  Recommendations on these items are solicited from the AIW via the
  APPN Architecture Reference mail exploder
  (aiw-appn-reference @ ibmstandards.cary.ibm.com).

  Meetings of the IETF SNA NAU MIB and SNA DLC MIB workgroups were held
  in which work continued on the definition of these standard MIBs.

  On the second day, Louise Herndon Wells summarized a research
  effort undertaken by Vedacom Corporation, in which comparisons were
  made between APPN and TCP/IP. Marcia Peters discussed the positioning
  of HPR. Kendall King discussed SNA over ASYNC and how vendors can
  expand product offerings to allow low-end users to take advantage
  of SNA and public networking. An update on APPN Implementation
  Validation was presented and a BOF on this subject also met over
  lunch.  Minutes for the Validation BOF can be found on the BOF mail
  exploder ([email-masked]).

  The Dependent LU Requester SIG met to continue work on the DLUR
  architecture. The architecture was granted AD status from the AIW.
  Minutes for the DLUR SIG can be found on the SIG mail exploder
  ([email-masked]).

  The High Performance Routing BOF met, with more than 52 attendees from
  more than 30 companies. The initial draft of the HPR specification
  was distributed and a brief introduction to the document was given.
  The group defined an objective and deliverables for future work,
  and a schedule was defined. The group requested SIG status, which
  was granted in the AIW wrapup meeting.  Minutes for this meeting
  can be found on the SIGs mail exploder
  ([email-masked]).

  The 'Vendor/Consultant' BOF met for the first time. This BOF was
  moderated by Tim Zeiher of LSI. Also meeting for the first time
  was the Bisync BOF, which explored BSC over APPN, and was moderated
  by Terry Bishop of Insession.

  On the third day, Terry Bishop, Insession, discussed markets for
  APPN End Node and opportunities for adding value to End Nodes.
  Diane Pozefsky presented an MPTN update which focused on vendor
  opportunities. Marcia Peters moderated a question-answer session,
  addressing questions which had been submitted by AIW participants.

  The meeting concluded with SIG/BOF reports and a wrap-up session.
