Abstract
Multicast addresses on a computer network are dynamically assigned to a temporary node task. In particular, a server dynamically assigns a multicast address to a data stream in response to a request for the data stream from a client. The server assigns the multicast address in cooperation with other servers from a pool of network-allocated but unassigned multicast addresses. Once the data stream is terminated, the assigned multicast address is deassigned and returned to the pool of unassigned multicast addresses for possible reuse by the nodes.
