Description
In this contribution, we focus on energy-aware devices
able to reduce their energy requirements by adapting their
performance. We propose an extension of an analytical model to
accurately represent the impact of green networking technologies
– namely, low power idle (LPI) and adaptive rate (AR) - on
network- and energy-related performance indexes. We focus on a
packet-processing engine within a switching node, where LPI and
AR are applied in the presence of multiple services that require
different processing times of the packet headers. Given a discrete
set of processing times with their probabilities, we extend our
previous modeling framework based on an Mx/D/1/SET queueing
system to take into account the presence of multiple service times.
We use the model to perform various numerical computations to
evaluate energy consumption and packet delay. The results
highlight how the proposed model can effectively be used to
produce analytical estimates of performance indexes that can be
the basis for the optimization of energy consumptionperformance
tradeoffs.
