Design and analysis of a dynamic Weighted Fair Queuing ( WFQ ) scheduler
نویسندگان
چکیده
This work aims to analyse different design proposals for a dynamic Weighted Fair Queuing (WFQ) scheduler to provide Quality of Service (QoS) guarantees in general at IP level and specifically for the applications of the PHOENIX project. Several possible design options and configuration parameters have been investigated and studied for a dynamic scheduling discipline able to support QoS in a relative manner according to factors pre-assigned to each queue at a given interface. Simulation results have demonstrated that this system can perform well in various network working conditions. Finally, guidelines for a designer and a network operator have been carried out on the basis of the analysis of several collected simulation results.

متن کاملE WFQ: An Energy Efficient Fair Scheduling Policy For Wireless Systems
As embedded systems are being networked, often wirelessly, an increasingly larger share of their total energy budget is due to the communication. This necessitates the development of power management techniques that address communication subsystems, such as radios, as opposed to computation subsystems, such as embedded processors, to which most of the research effort thus far has been devoted. ...

To improve the Quality of Service (QoS) ability of TNPOSS (To Next-hop Port Sequence Switch) network, this paper proposes a QoS-enhanced TNPOSS (QTNPOSS) network model by introducing Fractal Leak Bucket (FLB) shaper and Weighted Fair Queuing (WFQ) scheduler. In the proposed model, packets of multimedia traffic are shaped by the FLB shaper and scheduled by the WFQ scheduler. Moreover, the servic...
