A Multi-constrained Application-layer Multicast Routing Algorithm
Dong Wang · Science Technology and Engineering · 2006
Due to the difficulties in application of IP multicast, the application-layer network is being increasingly recognized as a general multicast service infrastructure. Aiming at the require in bandwidth and delay constrains, a new heuristic algorithm based application-layer multicast is put forward to build a minimum delay diameter multicast tree, which combining the breadth-first search with the adjustable depth selects the path that saves network resources without violating the constraints by the strategy function of bandwidth and delay . The results of the simulated experiments show that PCT could reduce diameter and delay of multicast tree and has an extensive adaptability.
