针对多路径并发传输模型的整体性能在部分通信路径性能突变时会急剧下降的多种原因进行分析,选取对性能影响最大的因素(传输延迟)进行了优化,提出了一种针对多路径并发传输模型的传输延迟感知的路径数据分配算法.通过结合各条通信路径的实际传输延迟来分配多条通信链路的数据发送量,以及各条路径上发送的数据分组序号,减少路径性能恶化对多路径并发传输模型整体性能带来的影响.分析和实验结果表明,所提算法能够相对默认的轮询数据分配算法取得较好的运行性能.

The performance of CMT association degrades remarkably when the performances of parts of paths deteriorate. Based on the analysis of different network configurations, a delay sensitive data allocation scheme was proposed to dis-tribute data to different paths over multi-diversity network with reference of their transmission delay, which is a key fac-tor to the whole performance. Meanwhile, the transmission sequence number of each chunk will also was considered. The result of analysis and simulation reveal the performance of our scheme can achieve much better performance than the original round-robin scheme.
