Abstract :
In this paper, we have designed a Multi-Frequency Scaling scheme for energy conservation of network devices, especially routers and switches. The frequency of components in a network device is scaled dynamically according to the real time workload. A Markov model is developed for performance analysis of this mechanism. We implement a prototype of this scheme in the data path of a general IPv4 router based on a real hardware platform - NetFPGA. Experimental results show excellent energy savings at the cost of a tolerable latency, under various ranges of traffic loads. Our work indicates the feasibility and possibility of deploying this mechanism into real network devices for energy saving.
