Recently, energy expenditures of the Internet have increased dramatically, raising energy issue of routers an urgent problem in relative research areas. In fact, much device surplus and redundancy are introduced during network planning for rarely appeared traffic peak hours and device failures, wasting energy most of the time. In this work, an energy-aware architecture is proposed for routers, which...
Energy efficient routers are important and promising devices in the roadmap toward green networking. In this paper, we explore this topic with a traffic aware design that can automatically adapt the router’s energy consumption to the network traffic in real time with transitions at the scale from microseconds to nanoseconds. In this paper, we make three contributions. First, we propose an energy efficient...
Due to the ever increased energy consumption, large research effort has devoted to the energy efficiency area. In this paper, a frequency scalable publish-subscribe filter forwarding node has been proposed and implemented for addressing this challenge. The frequency scaling filter can operate on three different frequencies, which adapts its capacity and power on different network throughput. Our work...
In recent years, a new internet architecture based on the publish/subscribe paradigm has been adopted by organizations such as the FP7 EU project PSIRP (Publish/Subscribe Internet Paradigm) and its follow on FP7 EU project PURSUIT (Publish/Subscribe Internet Technology). Furthermore, a publish/subscribe based zFilter forwarding node has been developed and implemented on the NetFPGA platform. The zFilter...
As efforts focus towards meeting the EU 20-20-20 targets, energy efficiency in wired networks is a key component not only because of the impact ICT can make in helping the 20% reduction target in greenhouse gases (e.g. replacing flights with video conferences) but also because of the energy savings that network operators can and need to make in running ICT Networks. Especially, as Internet traffic...
