Based on a delay differential equations model of TCPs congestion-avoidance mode different control schemes have been proposed. Here a robust controller is designed based on the known techniques for H∞ control of systems with time delays.EnglishActive queue management (AQM)Communication networksControl of uncertain systems with time delaysH∞ controlCongestion control (communication)Control system synthesisDifferential equationsFeedback controlMathematical modelsNetwork protocolsNonlinear control systemsRoutersTelecommunication networksUncertain systemsActive queue managementTransmission control protocolRobustness (control systems)On the design of AQM supporting TCP flows using robust control theoryArticle10.1109/TAC.2004.829643
