MULTI-REGION SOURCE ROUTED MULTICAST USING SUB-TREE IDENTIFIERS
摘要
A controller transmits a data packet to a node in a source routed forwarding network having a plurality of nodes configured to transfer data packets to one another via a plurality of links. The data packet includes a header. The header includes a source routed hop list defining a path of the data packet. The data packet is associated with a flow of data packets from a source to one or more destinations. The hop list includes a sub-tree identifier indicative of a multicast sub-tree.
