Today's network architectures are not able to cope with the Future Internet requirements, as they are too inefficient, power hungry, and ossified on the TCP/IP paradigm. In order to promote a viable evolution towards new protocols and paradigms, modern network routers should become programmable to allow a flexible management of both traffic flows and power states. In this respect, Software Defined...
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...
In this contribution, we focus on energy-aware devices able to reduce their energy requirements by adapting their performance. We propose an analytical model to accurately represent the impact of green network technologies (i.e., low power idle and adaptive rate) on network- and energy-aware performance indexes. The model has been validated with experimental results, performed by using energy-aware...
Due to the continuous growth of customer population, the spreading of broadband access, the increase in energy price, and the expanding number of services being offered by telecoms and providers, energy efficiency issue has become a high-priority objective for wired networks and services infrastructures. Current network devices are well-known to be over-dimensioned for rush-hour traffic loads, and...
