Energy Efficient Optical Burst Switched (OBS)Networks

This paper presents an energy saving technique for optical burst switched networks that reduces energy consumption without significantly degrading the quality of service (QoS) and the connectivity of the network. We propose a distributed algorithm using anycasting an communication paradigm, where the wavelength routed nodes (WRNs) adopt a sleep mode cutting the traffic routed through them. This paper also provides a mathematical framework for calculating the energy per bit (Eta) across the fiber and the wavelength routed node.
