Forwarding state reduction for sparse mode multicast communication Tian, Jining

Abstract

Reducing forwarding state overhead of multicast routing protocols is an important issue towards a scalable global multicast solution. In this paper, we propose a new approach, Dynamic Tunnel Multicast, which utilizes dynamically established tunnels on unbranched links of a multicast distribution tree to eliminate unnecessary multicast forwarding states. Analysis and simulation results show promising reduction in the state overhead of sparse mode multicast routing protocols.
