Title: METHOD AND SYSTEM FOR CLASSIFYING NETWORK DATA STREAM
Abstract:
Disclosed in the present application are a method and system for classifying a network data stream, the method comprising: collecting an information set of a data stream to be processed comprising a plurality of dimension information; establishing a static behavior model and a dynamic behavior model of each dimension information in the information set, the static behavior model characterizing a value selection rule of the dimension information, and the dynamic behavior model characterizing an association relationship between dimension information at a prior and subsequent moment; using the static behavior model and the dynamic behavior model respectively to acquire a static model distance and a dynamic model distance between the data stream to be processed and a data stream to which each target application type belongs; and determining an application type of the data stream to be processed on the basis of the static model distance and the dynamic model distance between the data stream to be processed and the data stream to which each target application type belongs.
