MULTILEVEL FEEDBACK QUEUE WAVELENGTH ASSIGNMENT ALGORITHM IN SURVIVABLE OPTICAL WDM NETWORKS

Abstract
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. Our aim is to achieve better protection without the need for extra resources. In this paper, we propose a new multilevel feedback queue wavelength assignment algorithm (MFWA) to minimize the blocking probability of the connection requests considerably. Simulation results indicate that the proposed MFWA algorithm achieves reduced connection drop rate and delay with increased bandwidth utilization and throughput.
