Several studies in the last decade have pointed out that many devices, such as computers, are often left powered on even when idle, just to make them available and reachable on the network, leading to large energy waste. The concept of network connectivity proxy (NCP) has been proposed as an effective means to improve energy efficiency. It impersonates the presence of networked devices that are temporally...
Today, backbone networks of telecom operators deploy a large number of devices and links. This is mainly due to both redundancy purposes for network service reliability and resource overdimensioning for maintaining quality of service during rush hours. Unfortunately, current network devices do not have power management primitives, and have constant energy consumption independent of their actual workloads...
