Detecting and handling network congestion in the Internet has, again, become a vital area of research. The provisioning of low latency together with high throughput is of particular interest due to the current mix of applications running in the Internet. Active Queue Management (AQM) mechanisms come with the promise of reducing queuing delays.

AQM stability in multiple bottleneck networks
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004In this paper, we highlight that multiple bottlenecks can affect the performance of active queue management controllers, which are usually configured on a single bottleneck basis, as if each controller were the only element regulating the TCP traffic along its path.

As an effective method for congestion control, active queue management plays an important role in improving the QOS of the Internet. We analyze the control mechanisms of typical transport layer protocols and AQM through dual theory, pointing out that although AQM is stateless, it has potential to improve flow fairness and stabilize queue length ...

Adaptive-CDM: A New AQM Controller to Cope with TCP/AQM Networks Dynamics
2005 5th International Conference on Information Communications & Signal Processing, 2006A new adaptive controller based on coefficient diagram method (CDM) as an active queue management (AQM) method is introduced. In the developed AQM (ACDM), the output feedback pole placement is implemented in an indirect model reference adaptive control (MRAC) scheme, in which the closed loop characteristic polynomial is determined by CDM and the system

Design of a robust AQM strategy for dynamic TCP/AQM networks based on CDM
Proceedings of 2005 IEEE Conference on Control Applications, 2005. CCA 2005., 2005A new robust AQM strategy for dynamically varying TCP/AQM networks is proposed. The developed AQM is designed based on coefficient diagram method (CDM), which is a new indirect pole placement approach that considers the speed, stability and robustness of the closed loop system in terms of the time domain specifications.

Constructive output feedback AQM design
Proceedings of the 2005, American Control Conference, 2005., 2005A novel constructive output feedback congestion controller is presented for asymptotically stabilizing a class of TCP networks at a desired operating point. An observer for the TCP window size is proposed to aid the task of designing AQM controller with only the output (queue size) measurement. Conditions under which the TCP window estimation converges

OpenFlow control for cooperating AQM scheme
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010OpenFlow is defined as a unified control plane and architecture for packet and circuit switched networks. We deal with the congestion control problem in the multi-layer network, and propose a cooperative congestion control scheme for a domain with multiple AQM routers based on the OpenFlow architecture. This scheme operates three different cases in the

The algorithms of queue management in IP routers determine which packet should be deleted when necessary. The active queue management, recommended by IETF, enhances the efficiency of transfers and cooperate with TCP congestion window mechanism in adapting the flows intensity to the congestion of a network.

Synthesis of PI–type Congestion Controller for AQM Router in TCP/AQM Network
2010This paper considers the problem of stabilizing network using a proportional-integral (PI) based congestion controller in active queue management (AQM) router, a necessary and sufficient condition on the network is determined for the existence of stabilizing PI controllers, which will present some general guidelines for the design of a stable PI AQM ...

The traditional adaptive Random Early Detection (RED) algorithm allows network to achieve high throughput and low average delay. However it uses a linear dropping probability function, which causes high jitter in the core router. To overcome the drawbacks of queue jitter in the traditional adaptive RED algorithm, this paper proposes a new Non-Linear ...
