An aggregated-based multicast strategy for MPLS

In this paper, on the basis of researching existing MPLS multicast approaches, we propose a new strategy named aggregated- based MPLS multicast (AMM). It merges group aggregation and tunnel technology, and can alleviate limited label space, reduce multicast forwarding states and strengthen robustness. This paper describes multicast tree setup and tear, aggregated and tunnel mechanism, and group members´ join and quit of the AMM.
