On Exploiting Flow Allocation With Rate Adaptation for Green Networking

Network power consumption can be reduced considerably by adapting link data rates to their offered traffic loads. In this paper, the authors exploit how to leverage rate adaptation for green networking by studying the following flow allocation problem in wired networks: given a set of candidate paths for each end-to-end communication session, determine how to allocate flow (data traffic) along these paths such that power consumption is minimized, subject to the constraint that the traffic demand of each session is satisfied. According to recent measurement studies, they consider a discrete step increasing function for link power consumption.
