In the earlier chapter describing nodes in
nsChapterchap:nodes, we described the internal structure of the
node in ns. To briefly recap that description, the node entry for a
multicast node is the
switch
_. It looks at the highest bit to decide if the
destination is a multicast or unicast packet. Multicast packets are
forwarded to a multicast classifier which maintains a list of
replicators; there is one replicator per source, group tuple.
Replicators copy the incoming packet and forward to all outgoing
interfaces.
