Abstract

Routers and switches are major contributors to the energy consumption of modern networks. Today, many energy efficiency metrics for these high-capacity devices are coarse-grained, i.e., based upon a single energy per bit value given at peak load or averaged over several specific loads. In this paper, we develop a new power model and a vendor-agnostic methodology that permits quantifying the energy efficiency of Internet equipment at a more fundamental level, i.e., at the granularity of per-packet processing, and per-byte store and forward packet handling operations. We demonstrate the efficacy of the proposed technique by applying it to various types of routers and switches. We describe how ..
