D.4 Protocol Independent Multicast - PIM
PIM, currently under development, is a multicast routing protocol
that runs over an existing unicast infrastructure. PIM provides for
both dense and sparse group membership. It is different from other
protocols, since it uses an explicit join model for sparse groups.
Joining occurs on a shared tree and can switch to a per-source tree.
Where bandwidth is plentiful and group membership is dense, overhead
can be reduced by flooding data out all links and later pruning
exception cases where there are no group members.
