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

Abstract

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

Energy Aware Data Centers and Networks: a Survey

“…RAPL for Intel processors [10] or PAPI specification [11], and, to some extent, the IPMI interface [12], allow to access power measurements related to some components of a computer system 2 . Unified interfaces, such as the green abstraction layer (GAL) [13], [14], are the next generation solution having the form of a generalized interface providing the functionality of setting energy states for all computer system components and also, which is another in- 2 Running average power limit (RAPL) provides access to various processor registers containing, inter alia, measurements of power consumed by processor components, cache memory, etc. While the original aim was primarily to provide power capping, these measurements are precise, short term averages relevant for designing dynamic processor frequency controllers [7].…”

“…The constraint (11) forces the cluster to work in a single energy-aware state, (12) and (13) are processing and memory capacity constraints. The most complicated, non-linear constraint (14) is the makespan limitation. Although the constraint (14) may be easily linearized, the resulting task complexity resembles that of the network control case.…”

Energy-saving Algorithms for the Control of Backbone Networks: A Survey

“…Modern network components, equipped with mechanisms for dynamic power management (e.g. InfiniBand cards switching between 1x and 4x mode or bundled WAN links [10], [11]), can operate in a number of energy states (K > 2), differing by power usage. Those extra states stand for power scaling and standby techniques.…”

Selective wakeup for parallel forward engines under variable load towards energy conservation in IP routers

“…6 Bolla's study on energy consumption describes, for a higher number of nodes, reduction of first 50%-80% of links doubles the energy savings. 9 The background studies reveal that the reduction of energy consumption in the communication medium is highly encouraged for the preservation of the environment and the minimization of operational cost. In this paper, we have designed an energy saving burst transmission technique for the router architecture with parallel FEs which has been designed in accordance with the emerging needs.…”

“…On an average, 1375nJ per packet is being consumed by metro IP router and Edge IP router consumes 1707nJ per Packet 6 . Bolla's study on energy consumption describes, for a higher number of nodes, reduction of first 50%–80% of links doubles the energy savings 9 . The background studies reveal that the reduction of energy consumption in the communication medium is highly encouraged for the preservation of the environment and the minimization of operational cost.…”
