Delay Asymptotics and Scalability for Peer-to-Peer Live Streaming

Free registration required

Executive Summary

A large number of peer-to-peer streaming systems has been proposed and deployed in recent years. Yet, there is no clear understanding of how these systems scale and how multi-path and multi-hop transmission, properties of all recent systems, affect the quality experienced by the peers. In this paper, the authors present an analytical study that considers the relationship between delay and loss for general overlays: they study the tradeoff between the playback delay and the probability of missing a packet and they derive bounds on the scalability of the systems.
