In this paper, we present a reactive control policy which adapts the source bit rate to the reserved resources in order to ensure performance guarantees for multimedia applications. The proposed method called flatness based trajectory tracking deals with drastic traffic flow rate changes and limits the traffic in order to respect the time constraints. We show the contribution of the reactive control and the dynamic regulation using purely control theoretic approaches which stabilize the network and avoid undesirable oscillations for the transmission of such critical flows. Here, we present a performance analysis for such rate control mechanism, and illustrate its feasibility through its implementation on MPLS-TE control plane of SSFnet/Glass simulator.
