Research of Application Level Multicast for Streaming Media
Wu Hui · 2007
Because most of end hosts in today’s Internet have limited access bandwidth and the Internet does not support IP multicast, a general end host can hardly provide service of real time streaming media applications. Application layer multicast is a novel communication method to solve this problem. The paper puts forward a two-tier application layer multicast framework for large-scale real time streaming media applications such as IPTV and VOD. Then how to construct and maintain overlay network between multicast service nodes is discussed. After that an application level multicast routing mode for overlay network and a routing algorithm based on intelligence ant colony are devised. A simulation experiment compared the routing algorithm with some other heuristic algorithms and the result shows that the routing algorithm is efficient.
