摘　　要：现有MPTCP的数据调度方案无法满足多路径的动态变化,出现链路传输性能降低的问题。通过对每条路径上的ACK数、往返时延进行预测,提出一种前向预测速度调度方法。利用NS-3对该算法仿真,表明该算法能提高吞吐量,更加合理,并使负载更加均衡。As the existing scheduling method of MPTCP could not satisfy the dynamic changes of the multi-path, the perform- ance of transmission was reduced. This paper gave a new data scheduling algorithm of MPTCP, named FPSA which used the knowledge of time and the number of ACK estimation on each path. The simulation results of NS-3 show that, this algorithm improves throughput, and is more reasonable and more balanced load.
