Abstract :
In this paper, the wavelength assignment problem in distributed optical networks is studied. We propose an improved dynamic and priority-based wavelength assignment algorithm-DPWA (Dynamic and priority-based wavelength assignment algorithm). This proposed DPWA algorithm can effectively reduce the average blocking probability and improve the wavelength utilization ratio by adding two dynamic factors related to the present wavelength utilization state. This improved algorithm can also satisfy different wavelength resources assignment aware of different service-level connection requests, which is more necessary and important in practical networks.
