BEAMBTS: A Distributed Bi-dirEctional Protocol of Aggregated Multicast Based on Tree Splitting
一种基于分发树切分的分布式聚集多播协议

With the enormous group communication applications,IP multicast confronts a severe scalability problem due to state explosion and control explosion.In backbone networks,this state scalability problem is exacerbated,since there are potentially enormous multicast groups crossing backbone domains.To improve the state scalability of multi- cast in backbone domains.This paper proposes a scalable protocol,called BEAMBTS(Bi-dirEctional Aggregated Multi- cast Based-on Tree Splitting),which uses the concept of aggregated multicast based on tree splitting.The analyses and simulations show that BEAMBTS can greatly improve state scalability:the number of aggregated trees is bounded in a small fixed number,and the multicast routing entries in transit nodes can be dramatically decreased.
