Minutes of the Inter-Domain Multicast Routing Working Group (IDMR)

The 27th IETF meeting in Amsterdam was the first official meeting of the
IDMR Working Group.  The working group met over two 2-hour sessions.

During the first session, Deborah Estrin gave a presentation on ESL
(work done in collaboration with Steve Deering, Dino Farinacci, and Van
Jacobson), one of the new proposals for inter-domain multicast routing.
The motivation behind the design of ESL was, for groups with a
relatively small number of senders (sources), to allow receivers to
receive data from those sources either over a shared tree, or over a
shortest-path tree rooted at the source.  The latter is useful for
applications requiring minimal delay between senders and receivers.  It
was agreed that, because ESL is in its early stages of development,
there remains specification and engineering details that need to be
resolved.

The second session was mostly dedicated to discussing the IDMR charter.
It was unanimously agreed that the current charter is lacking with
respect to many aspects of inter-domain multicasting, and it should be a
goal of the working group to try to resolve many of these, for example,
user group management and interoperability.

The conclusion of this discussion was that the charter should be
re-worked and re-submitted to the Routing Area Director after the items
to be worked on have been enumerated in order of priority.
