Approximate matching method, related device and communication system

Abstract

The embodiment of the invention discloses an approximate matching method, a related device and a communication system. The approximate matching method can include the steps that an unknown flow rate is obtained; similarity between the unknown flow rate and a sample flow rate is respectively calculated according to N dimensionalities; weighting harmony is carried out on the calculated similarity corresponding to all the dimensionalities to obtain matching similarity between the unknown flow rate and the sample flow rate, wherein N is an integer larger than or equal to two, and the N dimensionalities include the following dimensionalities: n1 dimensionalities related to a message of the flow rate, n2 dimensionalities related to a conversation corresponding to the flow rate, and n3 dimensionalities related to the flow rate, wherein n1, n2 and n3 are positive integers. According to the technical scheme of the embodiment, the improvement of efficiency and accuracy of a flow rate analysis is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an approximate matching method, related equipment and a communication system. Background technique [0002] Currently, broadband services bring opportunities as well as challenges to operators. Operators need to face a series of new issues such as bandwidth management, content billing, and information security. Among them, in the face of increasing service flow, Deep Packet Inspection (DPI, Deep Packet Inspection) technology is considered to be an effective method to deal with the management and control challenges brought by network multi-services. Regional traffic coverage is an important indicator to measure DPI capabilities. [0003] With the popularity of smart terminals such as smart phones, the number of applications has seen a blowout growth. And more and more applications (such as Skype, Vbuzzer, etc.) often evade the detection of DPI manufacturers by automaticall...
