In constructing an efficient multicast tree of application-level multicast, not only the delay of link should be considered, but also the process delay of many end systems in sending and transmitting data cannot be ignored. To solve the problem of "Minimum delay spanning tree", this paper proposed two routing models including the Minimum Radius, Degree-Limited (MRDL) model based on optimum delay and the LRRB model based on load balance. Moreover, this paper proposes corresponding heuristic algorithms. Simulation results prove these algorithms can transmit the media stream efficiently.
