Evaluation of adaptability of resource reservation methods for multiple multicast trees based on multiagents by simulation experiment

摘要

There are many research results for reserving an optimum multicast tree in the network. On the other hand, few research work has been done for reserving an optimum set of multiple multicast trees in the network. In this optimization problem, links shared by multiple multicast trees have to be taken into consideration. To solve the problem in a cooperative way, we have proposed multiagent based methods. In the design of these methods, not only optimization of multicast trees but also adaptability to successive changes in the network such as failure and recovery of nodes and links and addition and deletion of multicast members should be evaluated. We also proposed a function for evaluating such an adaptability. This paper evaluated adaptability of multiagent based methods by its function.
