摘　　要：本文提出一种基于流媒体服务的覆盖网络多路路由方案(SSONM)。本方案考虑了备选路径与主路径的关系,路径之间相交比较小,数据流出现拥塞的可能就比较小,提高了网络的性能和利用率。SSONM结合物理网络找出最短路径作为主路径,并计算其他路径与主路径之间的相关率,在进行多路选择时按照相关率从小到大顺序选择多路路径。该方案是一种简单可行的覆盖网络QoS多路选择策略,可以达到较少的包丢失率和较高的QoS请求满足率,可以很好地满足流媒体服务。An overlay network multipath routing scheme （SSONM）based on streaming media services is presented in this paper. The scheme takes into account the correlation cost between the primary path and other paths. If the primary path has little joins with other paths, the possibility of congestion is lower, the network＇s performance and utilization can be improved. The scheme selects the shortest path as the primary path by combining with the physical network topology. Then we calculate the correlation cost between the primary path and other paths, and choose the multiple paths by the order of the correlation cost. The scheme is a simple and efficient overlay QoS multi-path strategy. It can achieve a less packet loss rate and a higher QoS satisfaction rate.
