Heuristic Protection Algorithm in Multicast Multi-Domain Optical Networks
In this paper, we propose a new heuristic algorithm called Multicast Multi-domain Dedicated Protection (MMDP) to provide survivability in multicast multidomain optical networks. In route computation, MMDP considers the load balancing. To provide the intradomain protection, MMDP uses the modified Minimalcost Path Heuristic (MPH) algorithm to compute the intra-domain survivable multicast tree. To provide the inter-domain protection, based on multi-domain logical topology, MMDP firstly uses MPH algorithm to compute the inter-domain logical multicast tree and then uses Dijkstra algorithm to compute the interdomain logical backup sub-path for each inter-link on this logical multicast tree. Simulation results show that MMDP has better performances than traditional algorithm.
