Based on analyzing the basic packet pair bandwidth measurement algorithm, a theoretic proving of the algorithm is proposed. A measurement method named non uniform packet pair sequence bandwidth measurement is designed. This method can be used to solve the bottleneck link congestion problem existing in bandwidth measurement. In our measurement method, the basic back off time in generating packet pairs is defined and it can be adjusted with the change of the network traffic. The experiment results show that this method can generate measurement results which more accruately reflect the real bandwidth
