Due to complicated implementation of IP multicast, application layer multicast has attracted the attention of researchers. Tree overlay has some challenges such as resiliency problems caused by peer churns and also network resources may not be efficiently used. Mesh overlay doesn't have such problems, but has a high delivery latency and overhead caused by pull mechanism. Using a hybrid mesh/tree overlay...
Peer-to-peer (P2P) video streaming over the Internet plays an important role in reshaping today's Internet traffic. The performance of a P2P system is typically bottlenecked by the limited upload bandwidth of the participating peers, which typically have asymmetric upload/download bandwidth connections to the Internet. Increasing the streaming bitrate in P2P systems beyond what is sustainable with...
In a P2P network, the same content can derive from multiple sources, which is to say that there can be multiple incomings. As RTP used popularly in video streaming cannot handle multipoint-to-point data streams, R2CP was proposed to resolve this drawback. However, R2CP does not discriminate the data packets which are critical to the quality of video streaming, so there is a great risk that the critical...
