P2P Traffic Localization by Traceroute and 2-Means Classification
Liufei Wen, Yunfei Zhang · 2008
Most P2P system performance suffers from the mismatch between the randomly constructed overlays topology and the underlying physical network topology, causing a large burden in the ISP and a long RTT time. This document describes how DHT overlay peers can interact with the routers by traceroute to get the path information, and execute 2-Means Classification, thereafter peers leverage the DHT itself to build efficient closer cluster. This scheme only requires the infrastructure to enable traceroute queries. Conventions used in this document In examples, C: and S: indicate lines sent by the client and server respectively.
