SEM: a new small group multicast routing protocol
Résumé
Recently several multicast mechanisms [3], known as small group multicast, were proposed that scale better with the number of multicast sessions than traditional multicast does. In this paper, we propose a new approach, Simple Explicit Multicast (SEM), which uses an efficient method to construct multicast trees and deliver multicast packets. SEM is original because it adopts the source-specific channel address allocation, reduces forwarding states in non branching node routers and implements data distribution using unicast trees.
