| 摘 要： | 本文研究了多路径并行传输情况下接收缓存阻塞问题产生的原因及对传输性能的影响。同时提出了一种适用于多路径并行传输吞吐量分析的建模方法。该模型能够通过链路丢包率、往返传输时间等参数对吞吐量进行估计，并综合考虑了快速重传、拥塞窗口与接收缓存容量的关系对结果的影响。通过与仿真结果进行比较可以看出，该模型能够在网络性能参数发生变化时很好的预测吞吐量的变化情况。

| Abstract: | The reasons and influence of receive buffer blocking in Concurrent Multipath Transfer(CMT)environment are studied.A modeling method which is suitable for analyzing the throughput of CMT is also proposed.This model can be used to estimate the throughput according to the drop rate,round trip time and other parameters.It considers whether the fast retransmission is applied and the relationship between the size of congestion window and the volumes of receive buffer.Comparing with the simulation results,the mode... |
