摘要
For building a high-performance application-level multicast system, the key part is how to construct a stable distribution tree and adapt to network dynamics. CPN is a Peer-to-Peer overlay network with small world characteristic, the features of CPN grouping were utilized to propose an application-layer multicast model of multiple multicast source and multi-session, which uses each group to provide redundant services and perform good fault tolerance. The results show that CPN-Multicast has high performance, expansibility and good robustness to meet the demands of transmitting of large files on large scale networks.
