Proposal and Implementation of P2P Streaming System with Smooth Stream Switching Mechanism

With the spreading of broadband Internet access widely, live contents streaming service is now popular, and besides, Application-Level Multicast using peer to peer technique has been emerged as one of the best solution to reduce distribution costs on a server. However, the existing peer to peer streaming system has problems which cannot switch stream contents smoothly because a peer finds the parent peer which can send new stream contents only after decision of switching. In this paper, We present the design, implementation, and evaluations of a peer to peer media streaming system with smooth switching. In this system, peers construct backup routes beforehand and use one in case of switching stream channels. Each peer which has similar contents forms a group and constructs the backup routes on the other. Keyword P2P, Media Streaming, backup route, grouping, channel switching
