Characteristics of Network Delays in Wide Area File Transfers

Free registration required

Executive Summary

In this paper, the authors present an analysis of over 236,000 file transfers between 10 widely distributed Internet hosts. The goal of this paper is to broaden the understanding of how network path and congestion properties contribute to delays in TCP file transfers. The first part of the analysis investigates how end-to-end path properties (e.g. physical distance, router hops, autonomous system hops, or bottleneck bandwidth) relate to file transfer latency and variability. They evaluate end-to-end path properties as a predictor of file transfer latency, and employ dimensionality-reducing techniques to identify clustering in path space.
