This paper deeply and experimentally analyzes the efficiency of low power idle techniques when applied to packet processing engines of network devices. To this purpose, we set up a complex testbed that allowed us to perform several measurements on energy- and network-performance indexes. The reference device platforms that we selected for this evaluation are new generation software routers based on...
Many network-based applications require full time connectivity of the hosts for fate sharing and responding to routine applications/protocols heart-beat messages. Past studies revealed that network hosts are most of the time unused or idle but still kept powered on just to maintain network connectivity. Thus, significant energy savings are possible if the network hosts can sleep when idle. Unfortunately,...
The expansion of the telecommunication market to a wider number of customers, along with the increasing of services being offered, has brought the CO2 emissions to a dangerous level. Concern is due both to the impact on the environment and to the high costs caused by such energy consumptions. For these reasons, the scientific community is producing many researches to introduce power management capabilities...
