摘要:

针对以吞吐量性能为目标的多径并行传输协议设计,基于精确Padhye吞吐量模型,分析了活跃路径选择中带宽、时延、丢包率等表征路径性能的主要属性参数差异对多路径合成吞吐量性能的影响. 在此基础上,通过对等价参数和不等价参数情况下,路径差异对吞吐量性能影响的仿真,获得以吞吐量性能为目标的多径并行传输协议. 设计中,确定了活跃多路径选择的路径度量基本方法,为带宽合成的多径并行传输活跃多路径选择提供了理论参考.

关键词: 多径并行传输, 吞吐量, 活跃路径选择

Abstract:

Focusing on the active multipath selection of concurrent multipath transfer protocol, the influence of path metric disparity on the throughput performance of concurrent multipath transferring system was studied based on exalt Padhye model. With qualitative analysis, the influence caused by the path differences under equal and unequal path parameters was simulated and validated on the system throughput. Some basic conclusions on how to determine the path measurements were then presented; they can provide help to the selection of active multipath in theory.

Key words: concurrent multipath transfer, throughput, selection of active multipath
