我们报告了一种为监控几 Mbps 到 1000 Mbps 范围内的可用带宽而开发的新工具。该工具基于数据包对分散技术。它已经在 SLAC 进行了几个月的实验使用，并在 iGrid2002 和 SC2002 上进行了演示。它可用于检测由路由或拥塞引起的带宽变化。我们研究了交叉流量和路由器行为对探测数据包延迟的影响。本文介绍了这些分析的一部分以及对美国、日本和欧洲 12 条路径的监测结果。索引术语——可用带宽、色散技术、高吞吐量、测量工具、监控、网络、调谐、TCP。
We report on a new tool developed for monitoring available bandwidth in the range from several Mbps to 1000 Mbps. The tool is based on the packet pair dispersion technique . It has been in experimental use at SLAC for several months and it has been demonstrated at iGrid2002 and SC2002. It can b e used for detecting bandwidth changes caused by routing or congestions. We have studied the influence of cross traffic and the behavior of routers on the delay of the probing packets . The paper presents part of these analyses together with results from monitoring of 12 paths in US, Japan and in Europe. Index Terms—available bandwidth, dispersion technique, high- throughput, measurement tools, monitoring, networks, tuning, TCP.
