Fluid-based analysis of a network of AQM routers supporting TCP flows with an application to RED
TL;DR: This paper uses jump process driven Stochastic Differential Equations to model the interactions of a set of TCP flows and Active Queue Management routers in a network setting and presents a critical analysis of the RED algorithm.
Proceedings ArticleDOI
On designing improved controllers for AQM routers supporting TCP flows
TL;DR: A previously developed linearized model of TCP and active queue management (AQM) is studied, and the proportional integral (PI) controller is shown to outperform RED significantly.
Proceedings ArticleDOI
A control theoretic analysis of RED
TL;DR: This work uses a previously developed nonlinear dynamic model of TCP to analyze and design active queue management (AQM) control systems using random early detection (RED) and presents guidelines for designing linearly stable systems subject to network parameters like propagation delay and load level.
Journal ArticleDOI
Analysis and design of controllers for AQM routers supporting TCP flows
TL;DR: A recently developed dynamic model of TCP congestion-avoidance mode relates key network parameters such as the number of TCP sessions, link capacity and round-trip time to the underlying feedback control problem and analyzes the present de facto AQM standard: random early detection (RED) and determines that REDs queue-averaging is not beneficial.
Proceedings ArticleDOI
SOS: secure overlay services
TL;DR: This work proposes an architecture called Secure Overlay Services (SOS) that proactively prevents DoS attacks, geared toward supporting Emergency Services or similar types of communication, and demonstrates that such an architecture reduces the likelihood of a successful attack to minuscule levels.
