Applying Principles of Active Available Bandwidth Algorithms to Passive TCP Traces

Free registration required

Executive Summary

While several algorithms have been created to actively measure the end-to-end available bandwidth of a network path, they require instrumentation at both ends of the path, and the traffic injected by these algorithms may affect the performance of other applications on the path. The goal is to apply the self-induced congestion principle to passive traces of existing TCP traffic instead of actively probing the path. The primary challenge is that, unlike active algorithms, the authors have no control over the traffic pattern in the passive TCP traces.
