RE: can ssm and non-ssm colide ?

Ross,
I feel and have felt for some time the same way about the naming of ISM.  It
isn't symmetric with the naming of SSM, and does give the impression that
one is a standard and the other is something else.  I like your suggestion
of calling the original model of multicast SIM instead of ISM, it seems to
be the perfect name!
Mike

The term "ISM" ("Internet Standard Multicast") describes the current IP
multicast model, in which joins are done to multicast group addresses only,
and packets are received regardless of the sender.

By the way, I have to say that I dislike the term "ISM".  It's misleading,
because SSM is likely to also be a standard someday.

Instead, I'd like to suggest the term "Source-Independent Multicast"
("SIM").  This is not only more descriptive, but also more contrasts better
with "Source-Specific Multicast".
