Abstract:

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 net twork topology. Then we calculate the correlation cost between the primary path and other paths, and choose the multiple paths by the order of the corre   lation 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.
