Abstract：Based on experimental analysis, this paper firstly find that the throughput of concurrent partial path transfer is better than that of concurrent all path transfer when there are more difference of path characteristic parameters among paths in Concurrent Multipath Transfer (CMT) of Internet end-to-end transport layer, so, the necessity and influence of transmission path selection in Concurrent Multipath Transfer environment are discussed. Then, fitting relations to path throughput with a variety of loss rate and delay are establish. As path throughput to path welght, a transmission path selection strategy based on path weight (i.e., CMT-PW) is proposed, the realization of algorithm and pseudocode is given. The simulation reveals that CMT-PW policy outperforms than traditional CMT policy.
