In this thesis, we study the method to optimize topology for DHT-based multicast. We propose a DHT-based bandwidth adaptive multicast system that forcus on host heterogeneity, scalibility, fault tolerate. In our system, node’s bandwidth is firstly considered, result of this process is the basis for determining the level of the node and correlatively caculating node’s identify. Level of a node is used to define maximum number of its child nodes. As a result, in our model, each node is assigned an optimal numbers of child nodes to forward multicast data. Thus, our method can make tradeoff between depth of the multicast tree and bandwidth of every node and take advandtages of DHTs in main taining multicast tree in churn overlay. System chosen for implementation and avaluation is Chord. This model is called Bandwidth Adaptive Multicast over Chord: BAM-Chord.
