The Analysis and Simulation of a Hybrid Video Broadcast Architecture

摘要

Recent research efforts have demonstrated the promising potential of building cost-effective media streaming systems on top of peer-to-peer (P2P) networks. The P2P systems have long SETUP and SOURCE TO END delay. We proposes a hybrid architecture MTreeTV which combines the use of P2P networks with dedicated streaming servers, and was proposed to build on the advantages of both P2P and CDN paradigms. We offer a novel locality-aware overlay construction and scheduling algorithm to assure the effectiveness of P2P overlay. We also study the placement of the servers with constraints on the client to server paths and evaluate the effect of the server parameters. Through analysis and simulation, we show that MTreeTV supports fast channel switching (98%) with little CONTROL overload.
