In this paper, a new design for the network traffic balance method is presented. In optical network, the wavelength is one of the most important resources, and wavelength assignment is one of the main factors that affect the efficiency of the network utilization. The performance optimization of networks is actually a control problem. Traffic engineering should provide sufficient control in an adaptive feedback control system. The tasks of a controller consist of the modification of traffic management parameters, the modification of routing parameters, and modifications of resource attributes and constraints. With the traffic balance, the network operation will be more efficient and the network blocking may decrease.
