Based on a delay differential equations model of TCP's 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 managementTransmission control protocol (TCP)Congestion control (communication)Differential equationsMathematical modelsNetwork protocolsPacket switchingQueueing networksTelecommunication networksRobustness (control systems)Conference Paper10.1109/CDC.2003.1271812
