Characterizing end-to-end internet performance

摘要: The Internet has undergone dramatic growth in connectivity, use, and quality of service over the past several years. As this continues is used for increasingly diverse demanding purposes, it vital to understand how network applications behave across a wide range scenarios. In thesis, we have attempted characterize end-to-end performance at both layer application layer. At layer, concentrate on fundamental question constancy path properties. Today's networking practices often assume various forms underlying In order provide general guidance about when what time scales these assumptions are valid, gathered large measurement dataset using NIMI infrastructure then examined notions context four core properties: routes, loss, delay, throughput. At detailed discussion analysis large-scale application, content distribution networks (CDNs). CDNs recently emerged as popular mechanism delivering behalf origin Web sites. To test whether improve reality, conducted first based study CDNs, focusing they well perform terms client download time. Our not only timely, but also provides baseline an effective way evaluate systems applications. Throughout our study, paid considerable effort deal with difficulties introduced by tremendous diversity Internet. We hope that such allowed us draw realistic picture today's useful insights effectively design provision future network. Meanwhile, gather right set concepts tools can be applied aspects even traffic condition changes. might long-lived value.
