Peer-to-peer (P2P) on-demand streaming systems inevitably suffer from peers churn that is the inherent dynamic characteristic of overlay network. With frequent peer departure, a large amount of media data cached on peer disk turns offline and unavailable, which becomes the major reason of heavy server load. To address the above issue, a new proactive data replication mechanism is proposed and implemented...
How to improve the scalability and QoS of peer-to-peer on-demand streaming system based on unstructured overlay is still a problem. Researchers have proposed some memory based buffering schemes to archive the targets. Considering the limited space of memory on one peer, a new caching strategy, which can integrate memory-caching strategy with disk-caching strategy, is proposed to make full use of peers...
