Problems solved by technology
Because multiple games can share the same special port, the identification method based on the port number cannot identify the network protocol of each game in detail for multiple games that share a port; because the traffic differences between multiple web games are very small, based on The identification method of traffic statistical characteristics cannot identify the network protocol of each web game in detail; the message structure of different games is very different, and the method of artificially establishing regular expressions can only identify the game network protocol of a certain fixed message structure

Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0024] In one embodiment, the network protocol identification method, such as figure 1 shown, including the following steps:
[0025] Step S101: Perform a packet capture operation on the game to obtain a preset number of network data packets containing the name of the game;
[0026] Step S102: Compare the messages of preset lengths in each of the network data packets, and find the user information messages of the game according to the comparison results;
[0027] Step S103: Perform a game control operation and an image transmission operation on the game respectively, c...

The present invention discloses a network protocol identification method and system. The method comprises: performing a packet-capturing operation to obtain a preset number of network data packets that contain game names; separately performing comparison on a preset length of a packet in each network data packet, and finding a user information packet of a game; separately performing a game control operation and an image transmission operation on the game, and finding a game control packet and an image transmission packet of the game; separately performing regular expression matching on the user information packet, the game control packet and the image transmission packet; separately filtering the user information packet, the game control packet and the image transmission packet subjected to regular expression matching; and according to a filtration result, determining a network protocol of the game by combining the user information packet, the game control packet and the image transmission packet. According to the method and system disclosed by the present invention, the characteristic of the game is distinguished from that of other network applications, and the network protocol of the game is analyzed reversely, so that accuracy of game network protocol identification is improved.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a network protocol identification method and system. Background technique [0002] With the continuous development of network technology, various network download tools, online shopping, entertainment media and online games have also emerged, and various network protocols support the normal operation of these applications. Existing network protocol identification methods mainly include identification based on port numbers, identification based on traffic statistical characteristics and identification methods based on manually established regular expressions. Because multiple games can share the same special port, the identification method based on the port number cannot identify the network protocol of each game in detail for multiple games that share a port; because the traffic differences between multiple web games are very small, based on The identification meth...
