Abstract

A novel alternate routing algorithm is proposed on the basis of balanced load of links and tabu-search and the optimization of solution search and the link load variance and congestion realized.After the routing is chosen

the wavelengths are assigned to each optical channel by using the first-fit method on the ’longest first’ principle.Different routing algorithms are simulated under the static traffic pattern of the ring and mesh networks.The simulation results indicate that using the new algorithm

the best routing can be arranged by the full use of the network resources

thus effectively reducing the demand for wavelengths.
