Abstract


Flow - based measurement model is the focus of the study of high-speed network flow direction and the basis for the optimization and improvement of the measurement algorithm is directly related to the effectiveness of the flow measurement , flow measurement algorithms international and domestic development , and on this basis Difficulties and development direction of flow measurement algorithm , has a positive role for the further study of the high-speed network flow measurement algorithm . Bloom Filter - based algorithm , this paper data collection elements frequency of occurrence was the heavy-tailed distribution characteristics proposed algorithm - multidimensional the Bloom Filter algorithms ( MDBF ) the frequency of occurrence of a statistical collection of disparate elements . Characteristics of heavy-tailed distribution network mid-stream length was proposed in this paper MDBF algorithm is very suitable for convection in the high - speed network statistics and analysis . Characteristics of network measurements , timing algorithm proposed update method and repeat the minimum value method to reduce the calculation error, there may be to ensure the accuracy of the algorithm ; design based on high-speed networks based on multi-dimensional Bloom Filter flow measurement model , the model of the prototype and the C language , and clear the value and use of the measurement model . Published data sets by selecting from NLANR PMA group to test the validity of the measurement model . The experimental results show that the measurement model not only can effectively find long stream to take up a lot of resources in the network , and prepare for further network control and optimization , and can explore that may exist in the network worms and DDoS attacks , which proved herein designed flow measurement model can be used for the actual measurement process .
