摘要
In this paper, we introduce active network technologies to a video multicast system that can satisfy heterogeneous client requests in an efficient and effective way. We employ active nodes that adapt incoming video streams at the user's request by using transcoders or filters and then dynamically reorganize multicast sessions to accommodate clients. Simulation experiments demonstrate that our methods can appropriately split, merge, and move multicast groups to handle client-to-client heterogeneity.
