The policing mechanism with state-dependent control

A policing mechanism that can control the buffer read rate properly, according to the buffer state, is proposed. As this mechanism has the buffer with threshold, it has an intrinsically traffic shaping function and can control the bursty flow to some extent. Simulation results show that the authors´ model can easily manage the cell loss probability for a given buffer size by controlling the read rate according to the buffer state and has a certain margin in policing the peak cell rate, as well as the mean cell rate. If their read control scheme is combined with the connection admission control or the network resource management control function, bandwidth utilization can be optimized in the overall traffic control point of view
