In this paper, we focus on power-aware network devices, and propose a stochastic model to evaluate their performance quantitatively. More precisely, applying the Markovian additive process (MAP) to the arrival stream for network devices, we develop a stochastic dynamic power management (DPM) model with shutdown policy. Two performance measures for power-saving and processing; steady-state power consumption and throughput, are derived analytically for the DPM model. In numerical examples, we investigate the performance of the power-aware communication device with shutdown in terms of power-saving and processing.
