Protecting Bursty Applications Against Traffic Aggressiveness

In this paper a new mechanism called aggressiveness protective queuing (APQ), is described to control traffic in network devices. The method is based on the principles of the WFQ scheme and which uses dynamic weights for its operation. APQ uses a simple mechanism for tracking the resource usage by the flows and uses this accounting to properly and dynamically control the weights of WFQ. Also analytic results and simulation results are provided to demonstrate the effectiveness of APQ in controlling bursty traffic
