ALSO CALLED:
Protocol Independent Multicast
DEFINITION: Protocol-independent multicast (PIM) is a set of four specifications that define modes of Internet multicasting to allow one-to-many and many-to-many transmission of information. The four modes are: sparse mode (SM)dense mode (DM)source-specific multicast (SSM)bidirectional. The most common mode in PIM is the sparse mode. It is used for transmission of data to nodes in multiple Internet domains, where

PIM DEFINITION (continued):
it is expected that only a small proportion of the potential nodes will actually subscribe. Dense mode, in contrast to sparse mode, is used when it is expected that a large proportion of the potential nodes will subscribe to the multicast. In source-specific multicast, paths (also called trees) originate (or are rooted) at a single, defined source, whereas bidirectional PIM is not source-specific.The term "protocol independent" means that PIM can function by making use of routing information supplied by a variety of communications protocols. In information technology, a protocol is
