Redesigning an active queue management system
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005A robust proportional-integral-derivative (PID) controller is proposed for active queue management (AQM). A linear quadratic regulator (LQR) method is used to design the controller, named LQR-PID. LQR is a robust design technique as compared to classical gain-and-phase margin and dominant pole placement methods. The LQR-PID controller marks the packets

Auto-tuning active queue management
2017 9th International Conference on Communication Systems and Networks (COMSNETS), 2017Active queue management (AQM) algorithms preemptively drop packets to prevent unnecessary delays through a network while keeping utilization high. Many AQM ideas have been proposed, but none have been widely adopted because these rely on pre-specification or pre-tuning of parameters and thresholds that do not necessarily adapt to dynamic network ...

CHOKeD: Fair Active Queue Management
2015 IEEE International Conference on Computer and Information Technology; Ubiquitous Computing and Communications; Dependable, Autonomic and Secure Computing; Pervasive Intelligence and Computing, 2015This paper proposes CHOKeD, a novel stateless Active Queue Management (AQM) scheme, to provide fairness among competing flows in the Internet. CHOKeD protects responsive flows by penalizing unresponsive flows, and by allocating bandwidth fairly. CHOKeD features such as fairness, high throughput and stateless design are promising for its deployment over

Edge-based active queue management
IEE Proceedings - Communications, 2006In the paper, a new framework of active queue management, namely, edge-based active queue management (EAQM), is proposed. Conventional AQM schemes are required to be deployed at all routers in the network, and this involves significant upgrading to current drop-tail routers.

Although powerful and necessary to prevent network collapse, the congestion control mechanism of the TCP is not sufficient to avoid congestion. Since TCP sources exert a limited control of the network, and unresponsive flows, which do not slow down their sending rates when congestion occurs, may be present, the efficacy of end-to-end congestion control

Analysis of active queue management
Second IEEE International Symposium on Network Computing and Applications, 2003. NCA 2003., 2003Active Queue Management (AQM) is intended to achieve high link utilization with a low queuing delay. Recent studies show that RED, one of the most well-known AQMs, is difficult to configure and does not provide significant performance gains given the complexity required for proper configuration. Recent variants of RED, such as Adaptive-RED are designed

Active Sense Queue Management (ASQM)
2015 IFIP Networking Conference (IFIP Networking), 2015Active Queue Management (AQM) algorithms have seen a lot of attention in recent academic literature as well as in the popular press. The problem with traditional AQM is that it is designed to operate on queues at the IP layer. However, the problem popularly called bufferbloat can move about among many queues some of which are resistant to traditional ...

Active Queue Management in EGPRS
2006 IEEE 63rd Vehicular Technology Conference, 2006Active Queue Management (AQM) schemes such as Random Early Detection (RED) or Explicit Congestion Notification (ECN) for TCP-based traffic are important components of the General Packet Radio Service (GPRS) system performance because of potential traffic bottlenecks caused by, e.g., limited radio capacity.

Reduction-based robust active queue management control
Control Engineering Practice, 2007Abstract This paper is concerned with the design of improved active queue management (AQM) control schemes for time-delay systems taking into account explicitly the presence of delays in the controller design. A robust controller coping with uncertainties on the network parameters such as round-trip time and load variations is proposed. This is based

Active Queue Management Algorithms in DiffServ Networks
Journal of Software, 2005Summary: Current Assured Forwarding (AF) service in differentiated services (DiffServ) networks can provide stable guarantees in throughput, but is lacking of efficient schemes in ensuring queuing delay and loss ratio. By analyzing the steady state operating point of RIO, this paper proposes two active queue management algorithms with adaptive control ...
