A scalable multimedia streaming model based-on multi-source streaming concept

In a peer-to-peer (P2P) overlay network, a large number of peer processes (peers) cooperate by exchanging messages. In multimedia streaming applications like music streaming, multimedia data is required to be efficiently and reliably delivered to processes in a real-time manner. A scalable and reliable streaming service is required in P2P overlay networks since a large number of leaf peers asynchronously issue requests. In this paper, we propose a new model called the asynchronous multi-source streaming (AMSS) model where multiple content peers transmit packets of multimedia contents to each requesting leaf peer. Here, each of the content peers transmits different packets with some redundancy to the peer in order to be tolerant of faulty contents peer and packets lost. Even if some content peers are faulty and packets are lost, each leaf peer can receive all the packets in a real-time manner. Furthermore, even if a large number of leaf peers issue requests, each content peer can support the leaf peers with sufficient content service quality.
