Abstract

The invention provides a virtual deep packet inspection traffic analysis method and system. The virtual deep packet inspection traffic analysis method combines the network function virtualization (NFV) technology and the deep packet inspection (DPI) technology organically, and comprises the following steps: a stream information table based on a five-tuple array is set; an I/O receiving core allocates corresponding stream identifiers to received data streams based on elements of the five-tuple array, and adds the stream identifiers and the corresponding elements of the five-tuple array into the stream information table; and a working core parses the received data streams, acquires the stream identifiers, and identifies and counts up WEB accessing traffic according to a preset regular expression feature library file and the stream information table. The virtual deep packet inspection traffic analysis method and system are high in service identification accuracy, flexible in deployment process and high in expansibility, and can effectively improve the operation and maintenance costs and benefits.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a virtualized deep packet detection traffic analysis method and system. Background technique [0002] Network technology has become an indispensable part of people's daily life. In order to provide a good network environment and network services, network administrators or network service providers (ISPs) need to manage the stability and security of the network. Recognition and analysis also present higher requirements. [0003] In the prior art, a DPI (Deep Packet Inspection, deep packet inspection) technology is usually used to identify and analyze network traffic. Through DPI, we can understand the real needs of users, make full use of network resources, develop attractive value-added services, increase users' dependence and loyalty to the network, and build a better profit model. However, the implementation of the existing DPI technology requires a variety of ...
