Integrated routing protocol for multicast and anycast messages

A novel efficient and dynamic integrated routing protocol for multicast and anycast messages is presented. The contributions of the protocol differ from well-known shared-tree systems in two aspects: (1) Off-tree anycast configuration and routing: multicast sources use anycast routing to select a better path from the source to one router in the group in order to avoid congestion or any fault in the network. (2) On-tree router anycast configurations: The nodes in the shared-tree are formed into a virtual anycast group. The shared-tree approach is extended with capability of a group cores (anycast group). The simulation data demonstrates the efficiency of the protocol.
