Green traffic grooming in zone-based scalable optical networks
|
Abstract:
In the view of high blocking probability of Traditional Green traffic grooming algorithm in optical networks, a Green traffic grooming in zone based scalable optical networks is proposed and studied in this paper. On the basis of W+5 Auxiliary Graph Model, generating an auxiliary graph which only contains parts of network nodes, it is possible to find a suitable and shorter route by flexibility to expand the auxiliary graph. Simulation results show that in comparison with the Traditional Green traffic grooming algorithm, the proposed algorithm can effectively reduce the blocking probability and achieve the lowest average power consumption when traffic load is relatively high.
