An Empirical Model of Power Consumption in the NetFPGA Gigabit Router
Sustained exponential bandwidth growth of the Internet is threatened by concomitant increase in power requirements of network switches and routers. Recently, researchers have profiled the energy demand of commercial routing platforms and proposed ways to reduce network power consumption. However, the profiles are coarse-grained, and the platforms are inflexible for experimenting with new schemes for saving energy. In this paper, the authors consider the NetFPGA platform, which is a popular routing platform for networking research, and make three new contributions. They obtain fine-grained measurements of the power consumed by the NetFPGA Gigabit router over a range of packet rates and packet sizes.
