Abstract

An embodiment of the invention discloses an application type recognition method and network equipment. The method includes: extracting first server address information from a first data message of a received data stream; matching the first server address information with sever application information which is stored with corresponding relation of server address information and application types; and when the first server address information is matched with the server application information, recognizing an application type corresponding to the first server address information as an application type of the data stream. By creation of the server application information, when a data message is received, keyword extraction and rule matching are not needed, but server address information of the data message is matched with the server application information, and accordingly an application type of a data stream of the data message is recognized quickly, and application type recognition efficiency of message is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an application type identification method and network equipment. Background technique [0002] Deep Packet Inspection (DPI) technology is a traffic detection and control technology based on the application layer. Network devices can use DPI technology to identify Internet Protocol (IP) packets. IP packets are usually sent by Composed of IP quintuple and application layer data, the network device can detect and analyze the source IP address, destination IP address, source port number, destination port number, transport layer protocol, etc. in the quintuple, and can analyze the IP packet Analyze the application layer data to identify the specific application of the IP packet. [0003] In the prior art, when identifying the application of a message, it is necessary to extract keyword information from the application layer data of the message, match the keyword informa...
