摘要:对IP网络路径带宽的探测是目前网络研究领域的一个热点。本文提出了一种针对端到端的网络、基于包排队方式的双向双步长网络路径可用带宽的探测方法。该探测方法由时延监视和UDP发送两个进程组成,基于包的排队时延来获取路径的可用带宽,并通过采用双向双步长的方法来递增或递减UDP包的发送速率。所提出的探测方法可以明显减少探测次数和运行时间,从而降低探测带来的开销。实验结果显示,所设计的方法和技术是可行的和有效的。
The bandwidth measurement for IP network paths is a hotspot in network research area. A bi-direction bistep approach to the available bandwidth measurement for an end-to-end network path based on packet queuing is proposed in this paper. This approach consisting of delay tracing and UDP sending processes computes the available bandwidth of a path by the delay of packet queuing, and increases or reduces the sending rate of UDP packets through bi-direction bi-step. The proposed approach can obviously shorten the measuring times and running time, so the overhead of measurement is reduced. The experiment results show that the proposed approach and implementation are valid and effective.
