Deep packet inspection system and packet processing method

Abstract

The invention provides a deep packet inspection system and a packet processing method. The system comprises a management unit, a control unit and an execution unit, wherein the execution unit comprises an inspection module and a strategy control module; the management unit is used for saving and managing system information and is provided with a first interface used for interacting with an entity of the next generation network; the inspection module is used for performing deep packet inspection on data packets according to a recognition rule to acquire a first inspection result, and the recognition rule is a rule transmitted by the entity of the next generation network through the first interface; the control unit is used for transmitting a control strategy generated according to the first inspection result and the system information; and the strategy control module is used for controlling service flow in the next generation network environment according to the control strategy. The invention can control any service in the next generation network (NGN), so the quality of service can be ensured and the user requirement can be met.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a deep message detection system and a message processing method applicable to both NGN (Next Generation Network, next-generation network) and non-NGN environments. Background technique [0002] As operators increasingly demand controllable network traffic, devices with DPI (Deep Packet Inspection, Deep Packet Inspection) functions are more and more widely used in the network. DPI devices Capable of business data flow identification and business data flow control, working from the transport layer to the application layer (layer 2 to layer 7) of the OSI (Open System Interconnect) model, with high data flow processing capabilities, capable of network The carried services are identified and managed, and can be deployed on backbone networks, metropolitan area networks, and network devices within enterprise networks. [0003] In the NGN environment, RACF (Resource Access Control Faci...

Problems solved by technology

[0004] However, the above two methods cannot be applied to all services in the NGN network and are not universal. For example, the above two methods cannot be applied to certain services (such as games and key network services)
