Multi-cores uni-directional shared trees multicast routing protocol

CBT and PIM-SM are two typical intradomain multicast routing protocols. However, CBT lacks an efficient member management mechanism such as admission control and authentication for senders of multicast group, and PIM-SM lacks robustness. This paper proposes a new one, which can effectively solve the both problems through admitting senders at multiple cores and transporting packets in a uni-direction. Furthermore, the protocol is easy to implement.
