基于P2P的分域分组流媒体直播系统研究
omain and group based P2P live streaming media system
本文提出了一种基于P2P的分域分组的流媒体直播系统GPBS（Group and Partner Based Streaming），并用OPNET对GPBS和data-driven结构的算法进行了仿真。由仿真结果可以看出本文提出的系统解决了目前商用的PPLive等流媒体直播系统没有充分考虑节点位置的问题，并可以解决ISP（Internet Service Provider）间的广域网出口带宽受到限制的问题；由于分组中各个节点明确分工的机制，可以有效利用每个节点的资源，从而减小了时延。
his paper proposes a domain and group based P2P live streaming media system GPBS（Group and Partner Based Streaming）and uses OPNET to simulate GPBS and data-driven system. The simulation results show GPBS can solve the problem that the live streaming media systems such as PPLive don’t consider the peer’s locality which leads to cross ISP (Internet Service Provider) traffic. Because of the group mechanism of GPBS, peer’s resources can be fully used, which can reduce the delay.
