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.
