The embodiment of the invention discloses a method for realizing the control on the packet microwave rate. The invention is characterized in that the method comprises the following steps: receiving a traffic shaping control message including a microwave idle transmission bandwidth message and a committed burst message; and shaping the output traffic of packet service data according to the trafficshaping control message. The method realizes the traffic control by using first-order data exchange unit architecture, reduces the time-lag of handling the packet service in equipment and the function complexity of the system, and reduces the equipment cost.
