AQM Mechanism with the Dropping Packet Function Based on the Answer of Several $$PI^{\alpha }$$ Controllers

In this paper the performance of AQM mechanism based on three \(PI^{\alpha }\) controllers and the impact of traffic self-similarity on network utilization are investigated with the use of discrete event simulation modelling. The queue is divided into several thresholds. Each segment of the queue is controlled by a different \(PI^{\alpha }\) mechanism. We analyze in tests the length of the queue and the number of rejected packets. The results obtained by the proposed approach are compared to the results obtained for AQM mechanism based on single \(PI^{\alpha }\) controller.
