Abstract

The invention discloses a deep packet inspection method and a system. The method comprises: a preset data flow applied in a network is provided with an inspection template, wherein, the inspection template comprises a packet characteristic, a template characteristic and template action, and the packet characteristic, the template characteristic and the template action are stored in a characteristic repository; the template characteristic is used for specifying relation of different packet characteristics in the template; packet characteristic matching is carried out on the packet; template characteristic matching is carried out according to the packet characteristic matching result; corresponding template action is performed according to the template characteristic matching result. By means of the above technical scheme, the distinguishing ability of the deep packet inspection system is strengthened, the system design process is simplified, and popularity, expandability and the integral design efficiency of the system can be improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method and system for deep message detection. Background technique [0002] With the rapid development of Internet technology, more and more content is carried on the network, and network service providers also provide customers with more and more service content. At the same time, these services are differentiated according to different applications. This requires network devices to provide complex packet processing capabilities, to distinguish different applications, and to provide different levels of bandwidth for different applications. [0003] In the past, network devices used packet header information below layer 4 to distinguish unused applications. Commonly used ones were layer 2 MAC addresses and quintuples. However, as network applications become more and more abundant, different applications cannot be completely distinguished by packet header informat...
