Contrastive research on node selection strategy of ALM forwarding trees

Application Layer Multicast(ALM) has resolved the issue of deployment,but effectiveness inferiors to IP multicast.To build a high efficient multicast tree,the research is focused upon the influence on the communication efficiency of the multicast tree using three kinds of node selection strategy,which are based on Min-delay,Max-bandwidth,and Nearest network topology.The degree of nodes is limited to build the multicast tree at different network scale.Simulation experiments show that the strategy based on Min-delay is the lowest in average delay and average joining time,and is much more suitable for the delay-sensitive application.
