Abstract :
Fractional lambda switching (Flambda;S) is a novel proposal for the management of all-optical networks with sub-wavelength provisioning capability. The unique characteristic of Flambda;S is the utilization of the UTC (coordinated universal time) for alignment and switching. Several central research issues are still open in Flambda;S and need to be formally defined and analyzed. Within the scope of this paper, we introduce three novel switch architecture designs that are based on the use of tunable lasers. As an important goal, we introduce the notion "scheduling feasibility" that measure the number of possible different scheduling between an input and output time-frames
