Peer-to-Peer ( P2P) Multicast
The technology to distribute identical data simultaneously to multiple hosts is essential for large-scale applications such as file distribution, video distribution, and network collaboration. Although IP multicast, which is achieved in the network layer, is expected for such applications so far, several problems inherent in its original architecture delays the deployment of IP multicast into the Internet. We are now investigating Peer-to-Peer ( P2P) multicast architecture achieved in the application layer. In P2P multicast, data are duplicated at hosts and are transmitted to other hosts using multiple unicast connections. Therefore P2P multicast incurs no problem of IP multicast. P2P multicast, however, is subject to partition of the multicast tree caused by host´s leave or failure, because the tree is formed by end-hosts only. For the purpose of fast tree rebuilding, we are developing multi-path routing algorithm for P2P multicast.
