可用带宽是网络路由、流量工程、QoS控制中的一个关键参数,在可用带宽的测量参数中,除了与其密切相关的TCP吞吐量以外,缓冲区大小也在测量中起着重要的作用。本文讨论了现有的一些可用带宽测量技术,并通过在校园网环境中的实验测量结果,分析了在基于自拥塞和基于模型的两种测量方法中,缓冲区大小对可用带宽测量的准确性造成的影响。通过大量实验也可以看出Kperf 2.0.2在测量可用带宽时误差较大。
Available bandwidth is a key parameter in network routing, traffic engineering and QoS control. In addition to its closely related TCP throughput, the buffer size also plays an important role in the measurement of available bandwidth. In this paper, we discuss some of the available bandwidth measurement techniques and analyze the accuracy of the buffer size measurement of available bandwidth in both self-congested and model-based measurement methods through experimental measurements in a campus network environment The impact of. It can also be seen through a large number of experiments that Kperf 2.0.2 has a large error when measuring the available bandwidth.
