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 ...

Integrated ARM/AQM mechanisms based on PID controllers
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005The paper presents integrated mechanisms for differentiated service (DiffServ) architecture consisting of active rate management (ARM) at the edges of the network and two-color active queue management (AQM) controllers at the core of the network. The AQM controller is a robust linear quadratic regulator based proportional-integral-derivative controller

Adaptive AQM Routers Supporting TCP Flows
Dynamic Systems and Control, 2001Abstract This paper describes the development of an adaptive algorithm for active queue management (AQM) routers supporting a dynamically varying number of long-lived TCP flows. We use a nonlinear dynamic model of TCP behavior which was recently developed from fluid-flow and stochastic differential equation analysis.

CDM-based design and performance evaluation of a robust AQM method for dynamic TCP/AQM networks
Computer Communications, 2009A new robust AQM strategy for dynamically varying TCP/AQM networks is proposed and its performance is investigated through computer simulations in MATLAB and ns-2 environments. The developed AQM is designed based on coefficient diagram method (CDM), which is a new indirect pole placement method that considers the speed, stability and robustness of the ...

Small‐gain theorem and finite‐frequency analysis of TCP/AQM system with time varying delay
IET Control Theory & Applications, 2019In this study, for the first time, a stabilisation criterion is derived for the TCP/AQM system with time-varying delay and finite-frequency (FF) specifications. Two important results are established.

Stability analysis of PD AQM control for delay models of TCP networks
International Journal of Control, 2020This paper focuses on the local stability analysis of nonlinear delay models of transmission control protocol/active queue management (TCP/AQM) networks by using a Proportional-Derivative (PD) controller as AQM strategy.

A New DiffServ Supported AQM Algorithm
2006 8th international Conference on Signal Processing, 2006This paper gives a new active queue management algorithm for differentiated service (DiffServ) network, which is based on an new adaptive random early detection (RED) algorithm called pre-estimation RED, so we name it DiffServ PERED. PERED utilizes a short term discrete-time Markov queuing model to estimate the future queue state, then self-adjusts the
