Multicast congestion control based on hop to hop limited
基于逐段约束的组播拥塞控制机制研究

A new IP layer multicast congestion control algorithm based on hop to hop Radom Early Detection(RED),which is named STSR,was put forward,and its effectiveness was verified by means of mathematics.It was proved that STSR multicast congestion control had greater sensitivity and multicast transmission link had larger throughput.Simulation by applying NS-2 show that the STSR algorithm might ensure the TCP friendly as well as the distributed control theory of coarser granularity.While raising the IP layer multicast reliability and scalability,STSR guarantees the efficiency and quality to its greatest extent.
