ABSTRACT:
A “PeerStreamer” provides receiver-driven peer-to-peer (P2P) media streaming for loosely coupled P2P networks. Peers in the network perform only simple operations, may cache all or part of the streaming media, do not collaborate with other peers, may be unreliable, and may drop offline or come online during any given streaming session. Clients in the network operate in real-time to coordinate peers, stream media from multiple peers, perform load balancing, handle online/offline states of peers, and perform decoding and rendering the streaming media. In one embodiment, the PeerStreamer uses high rate erasure resilient coding to allow multiple serving peers to hold partial media without conflict, such that clients simply retrieve fixed numbers of erasure coded blocks regardless of where and what specific blocks are retrieved. In another embodiment, the PeerStreamer uses embedded coded media to vary streaming bitrates according to available serving bandwidths and client queue status.
