在对等（P2P）覆盖网络中，大量对等进程（对等点）通过交换消息进行协作。在音乐流等多媒体流应用中，多媒体数据需要以实时的方式高效、可靠地传送到进程。由于大量叶子节点异步发出请求，P2P 覆盖网络中需要可扩展且可靠的流服务。在本文中，我们提出了一种称为异步多源流（AMSS）模型的新模型，其中多个内容对等点将多媒体内容数据包传输到每个请求叶对等点。这里，每个内容对等体向该对等体传输具有一定冗余的不同分组，以便容忍有故障的内容对等体和分组丢失。即使某些内容对等体出现故障而丢包，每个叶子对等体也能实时接收到所有的报文。此外，即使大量叶对等点发出请求，每个内容对等点也可以以足够的内容服务质量支持叶对等点。
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.
