The paper addresses two issues: (i) modeling dynamic flows transmitted in vast TCP/IP networks and (ii) modeling the impact of energy-saving algorithms. The approach is based on the fluid-flow approximation, which applies first-order differential equations to analyze the evolution of queues and flows. We demonstrate that the effective implementation of this method overcomes the constraints of storing large data in numerical solutions of transient problems in vast network topologies. The model is implemented and executed directly in a database system. It can analyze transient states in topologies of more than 100,000 nodes, i.e., the size which was not considered until now. We use it to investigate the impact of an energy-saving algorithm on the performance of a vast network. We find that it reduces network congestion and save energy costs but significantly lower network throughput.

“…Five home networks (HN‐1, HN‐2, HN‐3, HN‐4 and HN‐5) have been deployed for highlighting the impact of the different HG power states. The access network cloud includes two distinct devices provided by Ethernity Networks, namely, a very‐high‐bit‐rate digital subscriber line digital subscriber line access multiplexer, labelled AN‐1, for residential or small business network terminations, and a customer premises equipment switch (AN‐2) for enterprise network access or backhauling of wireless terminations. The metro network cloud is composed of a typical ring topology of three metropolitan carrier Ethernet switches (MN‐1, MN‐2 and MN‐3), provided by Ericsson. The data centre cloud contains the most representative building blocks of a data centre, namely, a server equipped with a Mellanox high‐speed network adapter and a Mellanox high‐speed interconnection switch. Both the server interface and the switch work with the 40Gigabit Ethernet standard. The core network cloud contains two instances of the Distributed SW ROuter Project (DROP) , an open‐source router prototype composed of multiple modular elements based on the network functions virtualization scheme, envisaged by the ETSI as the next‐generation approach to router architecture. Two emulation networks, including a number of virtual routers implementing green routing strategies and protocol extensions, have been interfaced with the two DROP instances. The transport network cloud is composed of two physical nodes (TN‐1 and TN‐2) designed by Alcatel‐Lucent and of an emulation network aimed at representing the optical backbone transport network.…”

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

SummaryRecent studies have shown that a large amount of energy consumption in the communication medium occurs at the data processing plane. The data plane executes the forwarding decisions in the routers and switches. Through initial studies, the line card was identified as the most granular component of the router and later forward engine, a sub component of line card has been recognized as the most power intensive component of routers. Fundamental techniques like link rate adaption, sleep and wake‐up have been imposed to reduce the energy at line cards and forward engines. On the other hand, router's architectures undergo drastic changes like empowering data plane with parallel processing due to the rise of gigabit routers. In this paper, to increase the degree of local autonomy and better energy savings, we have adopted the parallel processing design and imposed a variable amount of traffic on different line cards. The existing parallel forward engines perform load balancing in synchronous manner. In our design, asynchronous behavior is imposed such that every line card could independently decide to wake up or turn off their forward engine based on the traffic parameters. We have done simulations and witnessed increased energy savings (average sleeping time) without compromising the completion of lookup process.
