InstantLeap: An Architecture for Fast Neighbor Discovery in Large-Scale P2P VoD Streaming

Free registration required

Executive Summary

In large-scale Peer-To-Peer (P2P) Video-on-Demand (VoD) streaming applications, a fundamental challenge is to quickly locate new supplying peers whenever a VCR command is issued, in order to achieve smooth viewing experiences. For many existing commercial systems which use tracker servers for neighbor discovery, the increasing scale of P2P VoD systems has overloaded the dedicated servers to the point where they cannot accurately identify the suppliers with the desired content and bandwidth. To avoid overloading the servers and achieve instant neighbor discovery over the self-organizing P2P overlay, the authors design a novel method of organizing peers watching a video.
