In survivable optical WDM networks, finding physical routes and assigning wavelengths to light paths plays a vital role in the information transmission systems. Wavelength Assignment (WA) problem is a major concern than assigning routes to the light paths. Earlier wavelength assignment algorithm suffers from unbalanced utilization of wavelength that leads to blocking probability for any connection request. The authors' aim is to achieve better protection without the need for extra resources. In this paper, they propose a new Multilevel Feedback queue Wavelength Assignment algorithm (MFWA) to minimize the blocking probability of the connection requests considerably.
