Abstract
In order to provide high quality communications over a best-effort network, an alternative to complex QoS control procedures is represented by generously over-provisioning the network resources. This approach has guaranteed in the near past reasonably performance for many applications, but it implies a waste of energy that today is unsustainable. This paper proposes an autonomous measurement mechanism, named G-Router, to allow an access node in the Internet to align its power consumption to either the maximum capacity the user traffic requires, or the minimum available capacity in the network path between source and destination. Simulation results show that allowing access network nodes to adapt the switching and transmission resources to the minimum between the above values, the G-Router guarantees the maximum QoS while minimizing the energy consumption.

QoS aware dynamic power scaling algorithms for deploying energy efficient routers
ANCS '14: Proceedings of the tenth ACM/IEEE symposium on Architectures for networking and communications systemsEnergy efficient routers (EERs) are promising devices to achieve green communications for ISP to save energy and cost. However, deploying this kind of routers may introduce severe accumulated packet delay, especially for high-end optical routers. In ...
