Multiple Tree Multicast in a Dynamic Environment
Multiple multicast trees have been shown to increase the performance of data distribution when compared with single tree multicast. Node loss and congestion changes the performance characteristics of the multicast trees. Multicast tree performance feedback can be used to determine the optimal tree to use based on the feedback. We further examine an optimizing methodology, Probabilistic Multicast Trees (PMT), for multiple multicast trees which makes use of the performance feedback, generates a probability of usage for each multicast tree based on that feedback and then makes intelligent choices about which multicast tree to use for a given packet in the presence of node loss and congestion.
Keywords: Dynamic Multicast, Application-Level Multicast, ALM, Probabilistic Multicast Trees, PMT, Adaptive tree selection, Content distribution.
