Empirically modeling how a multicore software ICN router and an ICN network consume power

Abstract

ICN (Information Centric Networking) has received much attention due to its built-in functionalities such as caching and mobility-support. One of the important research challenges is to reduce the power consumed by ICN networks because ICN's packet forwarding and packet-level caching are power-hungry. As the first step to achieve power-efficient ICN networks, this paper develops a power consumption model of a multicore software ICN router while taking into account the power consumed by power-hungry computation. This paper makes the following three contributions: First, the model is one of the first realistic models which consider ICN packet forwarding and packet-level caching. Second, the model is represented as a concise set of equations with just a few parameters. Third, we apply the model to estimate power consumed by simple networks.
