Abstract
A mechanism is provided by which a transport tree identifier can be generated using one or more identifiers for a multicast datastream. The transport tree identifier can then be used in the process of building a transport tree across a transport network. A transport network egress router can receive a request to join a multicast datastream from a downstream node outside of the transport network. The information contained in the join message that identifies the desired multicast datastream can be encoded in the transport tree identifier. The transport tree identifier can be related to one or more of a multicast group destination address, a multicast datastream source address, and a broadcast domain identifier.
