Parallel transmission model for real-time multi-source streaming of multimedia data in scalable networks

摘要

In a peer-to-peer (P2P) overlay network, large number of peer processes are cooperating 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. Scalable and reliable streaming service is required in P2P overlay networks since large number of leaf peer processes asynchronously issue requests. In this paper, we propose a new model named asynchronous multi-source streaming (AMSS) model where multiple contents peers transmit packets of multimedia contents to each requesting leaf peer. Here, each of the contents peers transmits different packets with some redundancy to the peer in order to be tolerant of faulty contents peers and packets lost. Even if some contents peers are faulty and packets are lost, each leaf peer can receive all the packets in real-time manner. Furthermore, even if a large number of leaf peers issue requests, each contents peer can support the leaf peers with enough quality of contents service.
