Abstract:

A new measurement method based on adaptive network framework was presented, which can dynamically adjust the resources allocated to each measurement task, so as to ensure that the user level requirements for measuring accuracy. A prototype system was designed, implemented and verified with three different kinds of network measurement business. The experiment data show that the proposed method has advantages in task accuracy satisfaction ratio and task rejection ratio. And it is proved the proposed method has higher accuracy compared with the traditional method.
