Wavelength routed network is capable of carrying the traffic grooming situations. The assigning of wavelength to routed path is one of the major facts that affect the blocking probability. This paper proposes a novel idea for assigning of wavelength called Max-Weighted Routing and Wavelength assignment algorithm for reducing the blocking probability and better performance. This algorithm focuses on weight factor which is calculated from number of total available wavelength, free wavelength and hop count along with load balancing factor. The results are compared with first fit, random, least used wavelength assignment with fixed, fixed alternate, adaptive routing, adaptive alternate routing.
