Minutes of the IP over Asynchronous Transfer Mode Working Group (ATM)

Agenda


   o Review Agenda.
   o Discussion of ``Multiprotocol Interconnect over ATM'' Internet
     Draft.
   o Status of other ATM Groups.
   o MAC Layer Proposal by John Burnett.
   o Presentation on ``Network Layer Architecture for ATM Networks'' by
     Fong Liaw, Sun.


The first half of the meeting was spent discussing the ``Multiprotocol
Interconnect over ATM'' Internet Draft written by Juha Heinanen.  The
document describes three approaches to encapsulating datagrams in ATM.
These can be divided into two classes:  VC Based Encapsulation, and
Multiplexing Encapsulation.

There is general agreement on the VC Based encapsulation method.  In
this approach, one protocol per virtual circuit, the Virtual Circuit
identifier is used to identify the protocol being carried.

The two approaches proposed for the multiplexing are roughly equivalent.
They differ in the manner used to identify the protocols being
encapsulated.  One uses NLPID (from Frame Relay) and the other uses
LLC's (from 802.x LAN). The Group was not able to agree on which was
preferred.  There was some agreement that it would be better to select
only one and that it was not good for uses of ATM to have to choose
between the two, but no consensus was reached.  The Group agreed to
change the name of the document to ``Multiprotocol Interconnect over ATM
using AAL5'' because it better describes the method chosen to do the
encapsulation.  A separate document may be written that describes doing
encapsulation using other ATM adaptation layer protocol.

Dan Grossman gave a presentation on the recent CCITT meeting.  He
reported that the differences between AAL3 and AAL4 have been resolved.
The have been merged to from AAL3/4.  AAL5 specification has been
completed and all major technical issues have been resolved.

Doug Hunt gave a presentation on the status of the ATM Forum.  The forum
completed its first major Document ``UNI Specification''.  They have
begun working on signaling for switched virtual circuits and traffic
management.

Fong Liaw gave a presentation titled ``Network layer Architecture for
ATM Networks''.  It addressed issues which have not been resolved in

                                   1





private ATM network architectures.  The topics included addressing,
routing, multicast, signaling and connection management, and
connection-less services.
