Following diagrams depict the architecture of the PIM:
SM operation is employed in environments where group members
are sparsely distributed throughout the network and bandwidth
is a constraint. For example, across many regions of the Internet
or if users are connected via ISDN lines.
DM operation is employed in networks where receivers are densely
populated in the network. It operates in a flood and prune approach.
Multicast trees are built by the data sent from the source.
