| 摘 要： | 组播作为一种节约网络带宽、降低网络负载的有效手段,在视频传输中具有广阔的应用前景。本文针对组播中的会话内公平性问题,深入研究了多速率组播分层解决方案的实现机制,并基于目前的研究现状和进展指出了分层组播现存的有关问题。同时为分析分层解决方案在解决组播会话内公平性问题中的有效性,文中通过网络仿真器NS进行了实验评价。

| Abstract: | As an effective method to economize the bandwidth and reduce the load of networks,muliticast will be widely applied in video information transmission in the future.Aiming at solving the problems of intra-session fairness that block multicast's advance,this paper penetrates with the research of layered mltirate multicast mechanism,and based on the research developments of layered multicast,some problems interrelated are proposed.In order to analyze the effectiveness of layered strategies in solving the intra-session fainess problems of multicast,an experiment by NS simulator is carried out in this paper. |
