“…Although multilayer resources can be joint scheduled, but the algorithm is too complex and the constraints are not reasonable. Now, many literatures are about IP/MPLS over WDM two-layer network [4][5][6][7][8][9][10][11][12][13][14]. In paper [8][9][10][11] ant colony optimization(ACO) is used for routing and can efficiently reduce blocking probability of two layer network.…”

In paper [12][13][14] genetic algorithm(GA) is adopted to solve routing and wavelength assignment(RWA) problem and can obtain a good performance. But these algorithms based on two-layer network can not be used in threelayer network.…”

IP/MPLS over WDM is regarded as the best solution for NGN (next generation network), but in current and future for a long time, network architecture is still three-layer of IP/MPLS over SDH over WDM. In order to make full use of resources and reduce the blocking probability in three-layer dynamic network, an integrated resources optimization algorithm is proposed. We propose two optimization modes in our algorithm: in optimization mode 1, the service blocked in upper layer can be transmitted in lower layer by its idle resources; in optimization mode 2, we regard the three-layer network as an integrated network and search route for each service in the integrated network. In order to transport each service in synchronous manner, an ACO-based routing approach is adopted in these two modes. The simulation results show that compared with other algorithms, our algorithm gets better performance than other routing approaches in terms of service blocking probability.

A dynamic equilibrated heuristic algorithm based on the D* principle and mixed-strategy game theory is proposed to resolve the restoration problem at the wavelength level in an automatically switched optical network (ASON). The cost of each edge and the wavelength occupancy was taken into account comprehensively. Nash equilibration between wavelength occupancy and path cost is solved and the evaluation function of the D* algorithm is constructed dynamically using game theory with a mixed strategy. Then, the system restores broken connections rapidly through dynamic route and wavelength assignment (RWA) and ensures a more balanced distribution of network resources in the process of dynamic channel restoration. Simulation results show that the blocking probability is reduced and the restoration probability is promoted effectively by this algorithm. In addition, the rapid and intelligent performance behavior of this algorithm can meet the requirements of restoration time.
