==Dense mode==

'''Dense mode multicast''' is one mode that [[multicast]] can use to construct a [[Tree (data structure)|tree]] for sending [[Packet (information technology)|packet]]s to the multicast subscribers. It is thean oppositealternative ofto [[sparse multicast]]mode.

The basic assumption behind dense mode is that the multicast packet stream has receivers at most locations. Sparse mode assumes relatively fewer receivers. Dense mode is ideal for groups where many of the nodes will subscribe to receive the multicast packets, so that most of the [[router (computing)|router]]s must receive and forward these packets (groups of a high density).
