Performance and Power Consumption Analysis of a Hybrid Optical Core Node

Hybrid optical switching (HOS) is a switchingparadigm that aims to combine optical circuit switching,optical burst switching, and optical packet switching on thesame network. This paper proposes a novel integrated controlplane for an HOS core node. The control plane makes use ofa unified control packet able to carry the control informationfor all the different data formats and employs an appropriatescheduling algorithm for each incoming data type. Threepossible node architectures are presented and an analyticalmodel is introduced to analyze their power consumption. Also,the concept of increase in power efficiency is introduced tocompare the considered architectures. The performance andpower consumption analysis of the node have been carried outthrough the use of a simulation model developed specificallyfor the scope. The obtained results show the effectiveness ofHOS networks.
