Embodiment Construction

[0018] according to figure 1 Schematic diagram of the structure, the system includes multiple receiving buffer modules and multiple corresponding CPU modules developed on the professional network card on the multi-core server, so as to accurately match the keywords of the received message content in parallel. At the same time, with the help of the dynamically maintained TCP connection flow table module, it is used for real-time identification and statistics of 102 Internet message protocols.

[0019] The present invention firstly opens up a plurality of packet receiving buffers on the professional network card, and binds the threads for processing buffer messages with multiple CPUs one by one, so as to realize accurate matching of the keywords of the received message content in parallel and Match result output.

[0020] Then, with the help of the flow table of the TCP connection, the real-time identification and statistics of the packet protocol are realized. Among them, the...

Abstract

The invention provides a system and a method for realizing a deep packet inspection technology based on multi-core and multi-thread. The system comprises a plurality of packet receiving buffer modules and a plurality of CPU (Central Processing Unit) modules. The system is characterized in that the packet receiving buffer modules are corresponding to the CPU modules so as to realize parallel accurate matching of keywords of the received packet contents. In the method, a plurality of packet receiving buffers are created, and the threads of the packets in the buffers are bound with the plurality of CPU one to one, so as to realize the parallel accurate matching of the keywords of the received packet contents. With the provided system and method for realizing the deep packet inspection technology based on multi-core and multi-thread, the load on the CPU is reduced, and the processing procedure of deep packet inspection is accelerated.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a system and method for realizing a deep message detection technology based on multi-core and multi-thread. technical background [0002] At present, the implementation of deep packet inspection technology is mainly carried out in the way of single-thread pipeline operation. When the amount of data processed is very large, the CPU burden is heavy, and the phenomenon of packet loss is prone to occur if the processing is not timely. [0003] Patent No. CN200710198554.7 (deep message detection equipment and method) discloses a deep message detection device and method, the method includes the following steps: (a) sending the message to be detected to the deep message detection device by the network processor Text data, including the message to be detected and the additional control information of the network processor, the control information includes the current...
