Abstract
In this paper, we propose a solution, called DQDMR, for generating delay-constrained bandwidth- appropriated multicast routing trees to reduce end-to-end delay and conserved bandwidth resources. At the current router system the router keep the information of link which neighboring node in the routing table to guarantee QoS(Quality of Service). When we construct multicast tree, DQDMR algorithm dynamically adjusts the path in the least delay and appropriate bandwidth. Through simulations comparing to another multicast algorithms, we reach a conclusion that DQDMR algorithm can simply and dynamically adjusts the construction of multicast tree in hight-speed and conserve bandwidth resources.
