Problems solved by technology

[0004] However, there are the following disadvantages in the prior art: first, the order of magnitude of the large-flow media data service request is very large, and the authentication in the service request needs to be completed by the gateway system, and the performance pressure of the gateway system is very high; second, due to the huge amount of DPI rule data , will reach the level of millions or tens of millions. Therefore, in the process of issuing DPI rules in batches, it will also put a lot of pressure on the performance of the gateway system; third, the DPI rules saved in the gateway system are regularly batched in the rule server It will take effect after being sent to the gateway system. This implementation method has a certain delay and the user experience is not good

Embodiment Construction

[0039] In each embodiment of the present invention, in order to overcome the problem existing in the prior art, the large-flow media data service request authentication function is completed in the gateway system, which causes a lot of performance pressure on the gateway system, and the DPI rule batch During the sending process, the performance pressure on the gateway system and the real-time performance are not strong, and the user experience is poor. A new authentication and dynamic rule server is added. When the user equipment uses the subscription service, if the DPI rule corresponding to the subscription service The authentication and dynamic rule server proposed by each embodiment of the present invention receives the service use request sent by the user equipment and authenticates the service use request. After the authentication is passed, The rule server sends the corresponding DPI rules to the gateway system. In this way, the DPI rule set of the gateway system is supp...

Abstract

The embodiment of the invention provides a DPI (Deep Packet Inspection) rule issuing method. The method comprises steps: an authentication and dynamic rule server receives a business use request sent by user equipment; the authentication and dynamic rule server authenticates the business use request according to pre-cached user information; and after the authentication is passed, the authentication and dynamic rule server sends the DPI rule corresponding to the business use request to a gateway system. The embodiment of the invention also provides a DPI rule issuing device.

Description

technical field [0001] The present invention relates to the network communication field based on Deep Packet Inspection technology (Deep Packet Inspection, DPI), in particular to a method and device for issuing DPI rules. Background technique [0002] DPI technology is a traffic detection and control technology based on the application layer. When Internet Protocol (Internet Protocol, IP) data packets, Transmission Control Protocol (Transmission Control Protocol, TCP) When the data flow passes through the gateway system based on DPI technology, the gateway system reads the content of the IP packet load in depth, and performs relevant refined operations on the flow according to various management rules defined by the system. [0003] In the prior art, requests for large-traffic Internet media data services, especially video streaming services, are authenticated through the gateway system, and the DPI rules used by the gateway system for data packets are batched by the rule se...
