一种基于pathchar算法的改进的网络端到端带宽测量方法

Improved Methods for Network Bandwidth Measurement Study Based on Pathchar Algorithm

在网络端到端带宽的测量中，Pathchar测量算法是目前网络链路带宽测量算法中最成功的算法之一，但是也存在不能对反方向路径上各段链路带宽进行测量、背景流量和逐跳误差累积影响等问题。本文提出一种改进的基于pathchar的测量方法较好的解决了上述问题，提高了测量的精度和抗干扰性。

In the network end to end bandwidth measurement, Pathchar measurement algorithm is the network link bandwidth measurement algorithm is one of the most successful method, but there can not reverse direction path to measure the link bandwidth of each paragraph, background traffic And the cumulative effect of per-hop error and other issues. This paper presents an improved measurement method based on pathchar better solve the above problems and improve the measurement accuracy and immunity.
