Abstract: This paper proposes an efficient distributed multicast routing algorithm that can always construct a QoS-constrained sub-optimal cost multicast tree if such a multicast tree exists. Analyses and simulations have been done to show that the algorithm has better performance than some other existing algorithms, especially under a tight QoS constraint, in terms of success rate, tree cost and stability. The characters above make the algorithm fit well the broad-band multimedia applications in the wide area networks which have a strict QoS requirement.
