Abstract
A new source based multicast routing with heterogeneous and dynamic receivers is proposed. Besides the general state information of the topology and the available bandwidth, two classes of group-specific state information such as the distribution of multicast tree and the highest receivable layer of on-tree nodes are also maintained at a router. Based on the above four classes of state information, the routing algorithm is designed to find a feasible tree branch satisfying a new member with its heterogeneous QoS requirement in terms of data layer and corresponding bandwidth. Compared with other related routing schemes, the routing performs better in such metrics as the routing control overhead, the routing success ratio and the bandwidth resources of the multicast tree.
