Translucent OBS Network Architectures With Dedicated and Shared Wavelength Converters

The deployment of translucent optical networks is considered the most promising short term solution to decrease costs and energy consumption in optical backbone networks. Indeed, due to the technological maturity of translucent Wavelength Switched Optical Network (WSON) architectures, they have already caught close attention from the research community. Moreover, recent advances and enhancements in optical devices are now (re-)fostering research interest in sub-wavelength technologies like, among others, Optical Burst Switching (OBS) and optical packet switching (OPS). Hence, in this paper, the authors evaluate and compare two novel node architectures for a Translucent OBS (T-OBS) network.
