Designing optimal energy profiles for network hardware
The energy management of computer hardware
mainly relies on primitives defined in the ACPI industrial
standard. Network devices can borrow the same concepts as a
basis for their energy-efficient design; however, to effectively
tailor network processors for their specific applications, the set of
energy-aware states defined by the ACPI and their parameters
should be carefully chosen. In particular when designing network
hardware, one should address the problem of optimizing
parameter values (most often chosen in a discrete set) to trade-off
energy efficiency and network performance. In this paper, we
provide a methodology for such choice, by investigating this
trade-off over a continuous spectrum of parameter values. This
approach will allow us to gain insight in the behavior of the
optimal solutions that achieve different desired tradeoffs
