In this paper, the congestion control problem in a single virtual circuit of a connection-oriented network is addressed. The network is modeled as a discrete time. n-th order system. On the basis of the state space description of the plant a feedback control law is derived by minimizing linear quadratic cost functional. Two controllers are proposed. The first one is obtained when the whole state vector is considered in the optimization procedure, while in the latter case the emphasis is placed on the output variable, with its influence on the cost functional moderated by a weighting coefficient. Closed loop system stability is demonstrated, and conditions for no data loss and full bottleneck link bandwidth utilization in the network are presented, and strictly proved, Since the rates generated by the controller are always nonnegative and bounded, the proposed scheme can be implemented in real systems.

    IEEE 802.16 standard suite defines a reservation-based bandwidth allocation mechanism. A SS (Subscriber Station) has to be polled to request bandwidth reservation before transmits uplink data to a BS (Base Station). In this mechanism exist two main polling modes: the unicast polling mode and the...
