Abstract
A method is implemented by a networking device functioning as a computing node. The method resolves sub-trees of a loosely specified multicast distribution tree (MDT). The method utilizes global identifiers for sub-trees of the MDT to enable differentiation of traffic destined for different sub-trees of the MDT at shared replication nodes. The method can be implemented at or for each of the nodes of the network that are part of the MDT.
