“…Moreover, the Fig .2 (a) and (b) also show that the RCP and the PTP do not affect the effectiveness of the frequency scaling [9,10]. With the RCP router as an example, its power consumption at 125MHz occupies the range of about 11.1W~12.3W with varying the traffic load from 100Mb/s to 1000Mb/s, and significantly reducing the core frequency, from 125MHz to 62.5MHz, can considerably lower the power to the range of 9.9W~10.7W over the same traffic load region.…”

“…From Fig .3 and Fig .4, it is also interesting to note that the frequency loweringinduced power reduction mainly comes from the 3.3V power component. This can be explained by the fact that the frequency scaling is undertaken by toggling the core frequency of the FPGA and the SRAM [8,9]. …”

“…For having an insight into the power consumption distribution of the router and more importantly, for the future green technology design, the explorations have also been undertaken in the NetFPGA-enabled gigabit reference router [9,10].The reasons for adopting the NetFPGA as a router platform [10] include (1) NetFPGA can provide a fast and convenient way to implement a practical router; (2) NetFPGA is an open source and reprogrammable hardware platform, based on which researchers can easily realize novel power-optimized network algorithm; (3) NetFPGA can offer fine-grained energy measurements for per-byte storage and per-packet processing.…”

Abstract-Energy efficiency is one of the most important issues in designing the future Internet. For examining an energy efficient router, in this paper, differnet routers such as rate control protocol (RCP) router, precision time protocol (PTP) router and reference router are compared in terms of the power consumption. The experimental measurements demonstrate that with varying the traffic load, the RCP router and the PTP router consume almost identical power which is about >1% higher than that of the reference router. This power degradation is observed to be from the 3.3V power component of the total power consumption and arises from the increased design complexity for implementing the RCP and the PTP onto the router. In addition, the down scaling of the NetFPGA core operational frequency is promising for reducing the energy consumption of the RCP router and PTP router.

“…Our previous work [4] [5] [6] implemented a proof-of-concept prototype, an energy efficient reference router with frequency scaling, on NetFPGA platform [7], showing the feasibility and stability of the design. This prototype can adapt its frequency dynamically on five stages, from 125MHz to 42MHz.…”

Energy efficient router is one of the most important and promising devices in the roadmap towards green communication and networking. In recent years, automatical power scaling adapting with real-time network traffic in a router has been proved to be practical on real hardware, which is an implementation under the traffic aware philosophy. In this paper, we further explore this direction, and present four real-time power scaling algorithms for the fine-grained energy management within a router. These algorithms are all based on the traffic aware philosophy. We first classify the traffic characteristics into three categories of the core router, access router and home router and analyze the differences among them. Then, we propose two design methodologies, periodical scaling and threshold scaling, and address four algorithms in details. Finally, we use real network traffic to evaluate these algorithms and draw the conclusions. The experiments on real traffic show that more than 40% of the energy in a router can be saved by using proposed system-level power scaling methods. Based on those evaluations, we also find that three status modes with two working frequencies and a sleep in a router are enough to achieve near-optimal energy efficiency by using our algorithms, which indicates an easy and practical hardware modification.
