Spatial composition method for end-to-end network measurement avoids lengthy measurements of a path and the path is divided into some sub-paths when multiple measured paths share the underlay network route. The performance of the overall path is estimated by spatially composing measurement results of the sub-paths. This method is quite effective for measurement in overlay networks where many paths...
The available bandwidth on an end-to-end network path is an important metric for detecting network congestion, adapting transmission rate, configuring paths and topologies on overlay networks, and so on. The existing available bandwidth measurement techniques aimed only at knowing available bandwidth of the bottleneck part on the path and most of them do not specify where is the bottleneck, and they...
