A queueing network model is used to analyse the performance of flow-control techniques. Analytical expressions for throughput and mean end-to-end delay are derived. Numerical results show that, under isarithmic control, the total network throughput is degraded significantly when the demand from one user is increased. Throughput degradation can be avoided if an end-to-end or a two-level control is used. Of these two schemes, the two-level control gives a higher throughput to the user with increased demand. This often results in a higher total throughput. The mean end-to-end delay of the various flow-control techniques is also characterized.
