SEM: a new small group multicast routing protocol
Ali Boudani, Bernard Cousin · 2003
Several multicast mechanisms, known as small group multicast, were proposed that scale better with the number of multicast sessions than traditional multicast does. 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.
