This work proposes a novel approach to reduce the power consumption of IP routers: freezing the forwarding engine of routers line-cards. In fact, recent studies showed that about 60% of the power consumption of a line-card is wasted to lookup the routing table during packet forwarding process. We first define the proposed approach, called Freezing Forwarding Functionality (F 3 ). Then, we...
Power consumption of information and communication technologies (ICT) has increasingly become an important issue in the last years. Both energy costs and environmental concerns call for energy aware “green” networking solutions in wired networks. Overlay routing is an attractive method to enhance the performance and reliability of routing mechanisms without the need to change the standards of the...
