Minimax Congestion Control for a Class of TCP Network Systems

doi:10.12068/j.issn.1005-3026.2019.08.001

Abstract

Abstract: The congestion control for TCP network systems with UDP(user datagram protocol)flows is studied. Firstly， a nonlinear TCP network model with a strict-feedback structure is established. Afterwards， a novel congestion control algorithm is proposed by using backstepping approach and minimax scheme， and a sufficient condition is provided. Furthermore， a state-feedback congestion controller is constructed by considering the maximum UDP flows to make the TCP networks stable. Finally， four different cases are simulated. Especially in the presence of maximum interference， the four different control methods are compared. The simulation results show the feasibility and superiority of the proposed method.

Key words: network congestion control, backstepping, minimax algorithm, UDP flow, disturbance
