A Fault-Tolerant Strategy for Multicasting in MPLS Networks

Multicast is an effective way for increasing the efficiency of network resources utilization. But when designed, MPLS did not consider the support of multicast. So multicast in MPLS has many problems. To solve this, we introduce and propose a new multicast strategy in this paper that combines ERM and AMFM. Compared with the previous multicast algorithms, it simplifies LSP setup and has less forwarding states. And it is fault-tolerant. So if implemented in MPLS networks, it can get a better performance.
