Novel Differentiated Service Methodology Based on Constrained Allocation of Resources for Transparent WDM Backbone Networks

Current Internet traffic comprises diverse service requirements. Service providers differentiate connections characteristics according to demand's requirements and pricing policy. In this paper we propose a differentiated service methodology that implements constrained resources allocation according to demand's priority level for WDM networks. With our proposed mechanism higher priority connections are guaranteed a larger amount of resources, still, lower priority demands are guaranteed a minimum level of service.
