Statistically Quality Assured Streaming Architecture For Dynamic Peer To Peer Networks

Abstract

In a peer to peer streaming system, the server usually provides multiple channels. Peers may form multiple groups, each corresponding to a channel for content distribution. A peer can freely switch from one channel to another. We propose a shared or distributed overlay framework (called SMesh or subset mesh) for dynamic groups where users may frequently hop between different groups. SMesh first builds a relatively stable mesh consisting of all hosts for control messaging and supports dynamic joining and leaving host in between the groups. And will guide the construction of overlay delivery trees. Through simulations on Internet, we show that SMesh achieves low delay and low link stress with efficient and low cost maintenance. Secondly we focus on providing statistically guaranteed streaming quality at channel level and individual peer level.
