Executive Summary

The goal of enabling ubiquitous video broadcasting on the Internet has been a long cherished vision in the networking community. Prior efforts aimed at achieving this goal based on the IP Multicast architecture have been unsuccessful. In recent years, Peer-To-Peer (P2P) streaming has emerged as a promising alternative technology, which has matured to the point that there are several commercial offerings available to users. While these developments are encouraging, P2P streaming systems are susceptible to attacks by malicious participants, and their viability depends on how effectively they can perform under such attacks. In this paper, the authors explore this issue in the context of mesh-based designs, which have emerged as the dominant architecture for P2P streaming.
