| 摘 要： | 近年来,基于P2P的大规模流媒体直播系统得到了广泛应用,但是应用层覆盖网与底层物理网络存在失配问题。针对该问题,提出了一种基于Vivaldi网络坐标算法的流媒体系统拓扑优化机制——NCSTO(Network Coordinate System in P2P StreamingTopology Optimization),通过采用双重采样和样本过滤器,能够有效地针对覆盖网进行拓扑优化,减少网络失配,提高系统运行效率,降低带宽浪费。

| Abstract: | With the wide deployment of P2P-based live streaming media system in recent years,the mismatch does exist between overlay network in application layer and physical network in base layer.To address this issue,in this paper,the NCSTO mechanism,a topology optimisation mechanism for streaming media system based on Vivaldi network coordinate algorithm,is proposed.By using dual sampling and sample filter,the NCSTO can effectively optimise the topology aiming at overlay network,and decrease the network mismatch,im... |
