The Asymptotic Behavior of Minimum Buffer Size Requirements in Large P2P Streaming Networks

Free registration required

Executive Summary

The growth of real-time content streaming over the Internet has resulted in the use of Peer-To-Peer (P2P) approaches for scalable content delivery. In such P2P streaming systems, each peer maintains a playout buffer of content chunks which it attempts to fill by contacting other peers in the network. The objective is to ensure that the chunk to be played out is available with high probability while keeping the buffer size small. Given that a particular peer has been selected, a policy is a rule that suggests which chunks should be requested by the peer from other peers.. The authors consider a number of recently suggested policies consistent with buffer minimization for a given target of skip free playout.
