Sharing Simple Wavelength Converters in Optical Packet Switching: Performance and Power Consumption Evaluation

This paper considers simple fixed-output wavelength converters to implement shared-per-node optical packet switching with wavelength domain contention resolution capability. Scheduling algorithm and logical performance analysis are presented in synchronous context. Packet loss probability is evaluated and validated through simulation, and results are applied for comparisons with previously proposed sharing schemes. Power consumption evaluation is also presented. The results obtained outline that the proposed architecture performs very close to the general shared-per-node scheme, while employing simpler components.
