APPLEIP Minutes

Minutes of the InterOp '91 meeting of the Apple-IP IETF Working Group.

The meeting started with the following Agenda:


   o MacIP
   o AURP
   o AppleTalk and SNMP
   o AppleTalk and PPP


The consensus of the Group was that the MacIP document should be
supplemented with some of the comments made by Tom Evans in an appendix
to the document as a set of implementers notes.  The Group also felt
that the specification is riddled with problems and that this
specification should be worked on to provide a long term solution.  The
author was willing to do this if he is not chartered to work on the long
term direction of this specification.

The MacIP document will be moved to the draft stage as soon as these
changes are made.

The AURP discussion then began Alan Oppenheimer of Apple led this
discussion.  The discussion started with a description of the protocol
changes between this document and the previous version of the document.
The changes are as follows:


   o Addition of Open-Req and Open-Rsp packets
   o Changes to zone-based packets

      -  Move into connection stream
      -  Combined into one packet type

   o Packet header changes
   o Changes to details of connection teardown

      -  Keep the one-way connections independent
      -  Only reset tickle timer on AURP packets

   o Calling out of transport as a separate layer ``AURP-Tr''


On the last subject there was heated debate on if this was the correct
way to design the protocol and it was stated that this may tie the
protocol to IP and not make it portable to other protocols.  The
following points were thought to be essential to allowing the protocol

                                   1





to be accepted as an internet standard.  The type of service required by
the underlying media should be called out specifically.  The transport
should be separated from the rest of the protocol so that other
transports could be used.  A state diagram should be included in the
document.

Some discussion on the ability of AURP to solve the problems of the
mythical customer were held.  Some real customers (Boeing and NASA)
expressed their doubts as to the need of this functionality in their
networks.

The state diagram of the AURP protocol will be specified and then the
document will be put in the Internet Drafts directory.

The next topic was AppleTalk and PPP. A preliminary document specifying
the use of SNMP over DDP was presented by Mike Ritter from Apple.  This
document is available on apple.com in the directory /pub/apple-ip.  The
AppleTalk MIB II document is also available there.  These documents are
also available on AppleLink in the Developer Support folder.

The final topic that was discussed was the start of work by this Group
on the AppleTalk over PPP specification.  Brad Parker has been working
with others on a preliminary specification for this functionality and
this will be available from him shortly.  This specification supports
much of the functionality that is available with the ARAP (Apple Remote
Access Protocol) specification that is available through APDA. Brad is
also working with the PPP Extensions Working Group to arrive at a
specification for dial back and security on PPP links.

The next meeting will be held in conjunction with the IETF meeting in
Sante Fe New Mexico Nov.  18-22, 1991.
