Since the packet processing delay,propagation delay and the impaction of the router clock skew greatly affect the probing results,the probing results are processed with the link utilization statistic(LUS) algorithm and the queuing delay of each probing packet is therefore obtained.

The article tries to syncretize enterprise′s Life cycle with economic cycle and innovation cycle and products cycle and enterpriser life cycle to build multisynthetic cycle curvy as bell-curvy.
