The paper investigates the balance between Quality of Service (QoS) and power consumption for a traffic queue. Automatic adaptation to the power of the packet processing engine is sought through a heuristics and an optimal control strategy. The study allows to track the behavior of the system over time, thus avoiding the optimization of the steady state behavior of the system, which is hardly applicable...
This letter addresses the problem of energy saving in packet processing engines of network devices. The case of a single traffic queue is considered. The aim is to guarantee a delay constraint while adjusting the power consumption and the queue service rate. A feedback control is used, which is adaptive to the statistical behavior of traffic sources. The feedback is exploited by a heuristics and an...
