摘要
提出了一种基于逐段随机早期检测(RED)的网络层组播拥塞控制机制STSR,并对其有效性进行了数学推证,证明了STSR组播拥塞控制将具有更高的敏感度,组播传输链路也将具有更高的吞吐量。利用NS-2对STSR拥塞控制进行了模拟,结果证明它能保证对TCP流的友好,并实现了较粗粒度下的分布式控制。STSR在提高网络层组播健壮性的同时,最大限度地保证了其服务效率与质量。
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.
