CONTENTION AVOIDANCE SCHEME IN QOS-BASED DATA INTENSIVE ALL-OPTICAL NETWORKS
In this paper, a new contention avoidance scheme called WLC (wavelength-weight Limited Constraint) has been proposed to extend a Path Computation Element (PCE) for lightpath establishment in QoS-based data intensive all-optical networks. WLC assigns a wavelength-weight to denote the concurrent reservation probability and then PCE could select several preferable wavelengths according to the weight for source node. It will block the new request step by step according to QoS level when the weight overflows. The experimental results show that WLC based on QoS level performs better in total blocking than the others under various traffic loads.
