Using energy criteria to admit flows in a wired network

Admission control in wired networks has been traditionally used as a way
to control traffic congestion and guarantee quality of service. Here, we propose an
admission control mechanism which aims to keep the power consumption at the
lowest possible level by restricting the more energy-demanding users. This work
relies on the fact that power consumption of networking devices, and of the network
as a whole, is not proportional to the carried traffic, as would be the ideal case [1].
As a result some operating regions may be more efficient than others and ”jumps”
may arise in power consumption when new traffic is added in the network. The
proposed mechanism aims to keep power consumption in the lowest possible power
consumption level, hopping to the next level only when necessary.
