Forwarding state reduction for sparse mode multicast communication
Tian, Jining · cIRcle (University of British Columbia) · 2009
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.
