Large-scale validation and benchmarking of a network of power-conservative systems using ETSI's Green Abstraction Layer

The increasing energy demands of networks and networked devices represent a threat to the development of the Future Internet. In this respect, recent research projects were devoted to extending next generation networks, architectures and protocols in the green direction. This paper presents a complex demonstration network specifically designed to assess the viability and the real impact of green networking mechanisms on industrial prototypes. The demonstrator reproduces a complete wire-line network chain from the core devices to the subscriber terminals, integrating quite a few green mechanisms able to interoperate efficiently and achieve significant reductions in energy consumption. The experimental results and the ensuing impact analysis show how the aggregation of multiple devices with green capabilities can guarantee a satisfactory performance level, while also allowing huge energy savings.
