Abstract: The traffic grooming problem in wavelength division multiplexing(WDM) mesh optical networks was investigated. Two dynamic traffic grooming algorithms using the fixed alternate routing (FAR) were proposed. The average block probability could be reduced by pre-balancing the traffic in the network, and lower time complexity could be acquired simultaneously with the algorithms. The simulation results show that the network performance can be improved significantly by these algorithms.
