追踪路由算法在P2P流媒体节点分配的研究

纵观现有P2P流媒体技术,伙伴节点（Peer）的分配都采用随机策略,而忽略了伙伴节点之间的距离远近和通信连接状况,从而导致网络的总体传输能力下降。论文针对上述问题,提出了追踪路由的算法发现并分配伙伴节点,提高节点间的带宽利用率和数据共享能力。同时还对追踪路由算法建立数学模型,对其仿真进行了分析,收到良好效果。

Research on Trace Route Algorithm for P2P Streaming Peer Distribution

As known to all that the current P2P streaming uses the randomized policy to assign peers. It ignores the distance and condition of the network connection between peers. The randomized policy would lead the narrow band or large delay between peers. So this paper proposes the Tracer Route algorithm to find and group the peers. And with the Trace Route algorithm one can fully use the capability between peers to share the data. Meanwhile, one can construct the math- ematical model to calculate the Trace Route algorithm and analyze its performance by simulations, and obtains good results.
