| 摘 要： | 提出了一种基于逐段的网络层组播拥塞控制机制，对其有效性进行了数学推证，证明了信息包在不同优先级的转发约束下，STSR拥塞控制模型的缓冲区共享策略发生拥塞的概率小于分用策略，证明了在组播信息包的优先级高于非组播信息包的前提下，具有组播转发优先的STSR组播拥塞控制模型其缓冲区共享策略，更优于具有同等优先级的组播拥控模型的共享策略，这一结果的取得对于拥塞控制的相关研究具有很大的指导意义。

| Abstract: | This paper puts forward a kind of IP layer multicast congestion control algorithm according to hop to hop,and proves its usefulness based on mathematics,proves the STSR congestion control algorithm has a smaller congestion probability under the buffer area sharing than separating on the information frames transmit under the different priority policies,the STSR congestion control algorithm responding sensitively to network congestion and having larger networks throughput.It simulates the STSR model with NS-2,proving the STSR algorithm can ensure the TCP friendly and realize the distributed control theory of coarser granularity.This conclusion has great realistic significance to the multicast congestion control research. |
