| 摘 要： | 在分析固定随机选择邻居节点算法的基础上，提出了一种适用于混合式P2P直播系统的邻居节点随机可变选择算法，新算法通过能力因子来衡量节点的良好度，对不同类的节点有不同的邻居数量的最大值，使得良好度高的节点能发挥更大的作用，仿真表明算法能降低数据传输的延迟，提高网络系统的性能。

| Abstract: | Based on the analysis of the algorithms of fixed random neighbor selection,a new variable random neighbor selection algorithm adaptable to hybrid P2P in live multimedia streaming networks was presented.The new algorithm measured fitness degree of node with its capacity factor.Different types of nodes have different maximum neighbors.Simulations show that the new algorithm can reduce the transmission delay and improve the performance of network system. |
