> 中文摘要: 针对多路径并发传输模型的整体性能在路径性能存在差异时会急剧下降的原因进行分析,给出了获取通信路径传输时延的有效评估方案,并在此基础上提出了一种基于传输时延预测的多路径并发传输数据分配算法.该算法通过获取和预测数据块在各条路径上引入的传输时延,以按序到达为目标对多路径并发传输模型发送回合内和发送回合间的数据分配过程进行优化,能够有效地减少路径传输性能差异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,该算法相对于默认的轮询数据分配算法能够取得较好的运行性能.
Abstract:The performance of a CMT association degrades remarkably when the transmission capabilities of its paths are diverted. Based on the analysis of different network configurations, a transmission delay prediction based data allocation scheme is proposed to distribute data to different paths with a feasible delay measurement mechanism. To reduce the impact brought by out of order packet, the proposed scheme improves the data distribute process of inter and intra transmission round by accessing and predicting the arriving time of each packet in each path. The result of analysis and simulation reveal the performance of the presented scheme can achieve much better performance than the original round-robin scheme.
