To solve the dynamic traffic grooming problem in WDM mesh networks,we propose a resource efficiency grooming scheme based on the transceiver saving auxiliary graph model, The scheme considers both two network resources of transceivers and wavelength-links. It dynamically changes grooming schemes to improve the resource utilization according to the current network state. Using this scheme,it will not happen that all traffic are blocked for the shortage of one resource and another abundant resource is wasted,so both resources are utilized efficiently. The scheme can be achieved by the weight assignment to different edges on the auxiliary graph model according to the number ratio of the two resources, Simulation results show that the scheme achieves a good performance and reduces the network blocking probability.
