Flow Driven Energy-Aware Routing Algorithm in Data Center Network

摘要

Recently, many energy-aware routing algorithms are proposed to decrease the energy consumption of data center network. However, these methods ignore the effect of working time on energy consumption. In this paper, we analyze the energy consumption model and propose an energy-aware routing algorithm by jointly considering power consumption and working time. According to the simulation results, the flow driven energy-aware routing algorithm saves nearly 50 percent of energy compared with flow preemption energy-aware routing algorithm when transmission rate is limited by the available bandwidth, while it saves about 58.3 percent of energy compared with flow aggregation energy-aware routing algorithm when the transmission rate is limited by the forwarding rate of server's NIC.
