Abstract To eliminate the affect of the change of resource information on the QoS multicast routing, an algorithm for Distributed QoS Multicast Routing with Resource Reservation(DQMTR) is put forward in this paper. Using resource reservation in the process of path-detecting, DQMTR overcomes the issue. By noting the number of reserved resource, DQMTR resolves the issue of over-reservation. This paper considers the characteristic of differentiated services model to which DQMTR is adapted. The simulation reveals that the algorithm improves the success ratio, and optimizes the average path cost.
