Embodiment Construction

[0042] The in-depth message inspection system and method according to the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] First, the in-depth message inspection system according to the embodiment of the present invention will be described in detail with reference to FIG. 1 to FIG. 3.

[0044] As shown in Fig. 1, the hardware deep packet inspection engine according to the embodiment of the present invention specifically includes:

[0045] The input data buffer unit 101 is configured to receive a message to be checked from the main processor chip, and buffer the received message to be checked in the input data buffer unit, and wait for further checking; the input data buffer unit It is a standard first-in, first-out queue, so the first-arrival packets are always sent for inspection first;

[0046] The data distribution control unit 102 is used to read messages from the input data buffer unit 101, ...

Abstract

A inspecting system of deep message comprises data dividing-controlling unit for judging initial position of message inspection according to preset control information and for sending out message data before said initial position through speed-up channel as well as for send out message data behind initial position then making inspection, analysis unit for making inspection on message data behind initial position and for controlling said dividing-controlling unit to send out message data after key character through speed-up channel when required key character is inspected out.

Description

Technical field [0001] The present invention relates to the field of data communication technology, in particular to an in-depth message inspection system and method. Background technique [0002] With the rapid development of Internet technology, network service providers provide customers with more and more service contents, and differentiate these service contents according to different applications. This requires network equipment to provide more complex message processing capabilities, be able to distinguish different applications, and provide different levels of bandwidth for different applications. [0003] At present, network equipment distinguishes unused applications through packet header information below layer 4, and commonly used layer 2 MAC addresses, quintuples, etc. However, as network applications become more and more abundant, it is no longer possible to completely distinguish different applications by simply relying on the header information below the 4th layer...
