Performance Analysis of a Simple Power Saving Scheme for Energy Efficient Ethernet

Abstract:

In order to improve the energy efficiency and build a green Ethernet, we propose a simple power saving (SPS) scheme with a burst transmission for Energy Efficient Ethernet. In SPS scheme, let the link transfer to the sleep mode as soon as no packets are ready for transmission, whereas let the link return to the awake mode when a fixed number of packets arrive during the sleep mode. We build a vacation queueing model with N strategy to describe the working principle of SPS scheme. By using the method of embedded Markov chain, the formulas of performance measures are given. Finally, numerical results are provided to show the impact of traffic load on system performance.
