Active Queue Management (AQM) takes a trade-off between link utilization and delay experienced by data packets. From control point of view, it is rational to regard AQM as a typical regulation system. In this paper, a new fuzzy adaptive second order sliding mode controller is designed for the objective of AQM. In the proposed method, the sliding parameter is adapted using fuzzy logic. Some comp...

This paper describes and evaluates the use of steady-state TCP behavior knowledge for proactive queue management (PQM). We show how routers can use flow parameters and the knowledge of TCP end-host behavior to intelligently mark packets to prevent queue build-up, and thus prevent congestion from ever occurring, while at the same time provide high link utilization and low packet loss. This is in...

In this paper, we propose a per-class queue management and adaptive packet drop mechanism in the routers for Internet congestion control. We model active queue management as an optimization problem and our proposed mechanism provides congestion control and fairness for different types of traffic flows. An optimal packet drop rate is obtained to maintain a relatively small queue occupancy, which...

—This paper presents and analyses the implementation of a novel active queue management (AQM) named FavourQueue that aims to improve delay transfer of short lived TCP flows over a best-effort network. The idea is to dequeue in first packets that do not belong to a flow previously enqueued. The rationale is to mitigate the delay induced by long-lived TCP flows over the pace of short TCP data req...
