In this paper, the control of Hopf bifurcation in an Internet congestion model with a single link accessed

by a single source is presented. By choosing the gain parameter as a bifurcation parameter, it is found that

the system without control cannot guarantee a stationary sending rate. Furthermore, Hopf bifurcation occurs

when the positive gain parameter of the system exceeds a critical value. For Internet congestion model,

a control model based on delayed feedback is proposed and analyzed for delaying the onset of undesirable

Hopf bifurcation. Numerical simulations are given to justify the validity of delayed feedback controller in

bifurcation control.
