In environment when power-saving routers and switches exist in an end-to-end path, since the amount of bandwidth-related resources of an end-to-end network path changes over time, the accuracy of existing end-to-end measurement methods of available bandwidth may degrade. Furthermore, the energy efficiency of power-saving routers also decreases due to additional traffic load by bandwidth probing. In...
The increase in energy consumption associated with ever-intensifying network traffic is becoming a major problem. A number of researchers have focused on technologies that dynamically adjust the processing performance and the link speed of routers according to the network traffic load in order to achieve energy-efficient networking. However, when such power-saving routers are present in an end-to-end...
