Abstract: A clampdown traffic method is proposed to control the volume of QoS link state advertisement(LSA). The simulation results prove that by using the clampdown traffic method, the higher network utilization efficiency and lower rate of link failures can be obtained, comparing with the currently used clampdown time method for the same LSA. Furthermore, a new method utilization prediction is proposed based on the characteristic of clampdown traffic method. The results show that the clampdown traffic method gets more characteristic improvements than the clampdown timer method when using the utilization prediction.
