System and method for classifying deep packet inspection facilities

Abstract

A system and method for performing classification on deep packet inspection (DPI) devices are provided. In the scheme of the present invention, a collection process module of the device information classifies each DPI device arranged in the same network layer into DPI controlling device group or DPI identifying device group based on the function types of the DPI devices, the DPI controlling device group implements management and control of service traffic, and the DPI identifying device group implements DPI identifying, DPI division and DPI sign; it is simple and efficient to perform uniform management and control on all the DPI devices arranged in the network, to satisfy various linkage requirement of the DPI devices, furthermore to make each DPI device to be able to cooperate in harmony and credibility, to implement linkage control based on all network DPI identifying devices, such as traffic partaking, fault processing and relating identifying etc.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a system and method for classifying Deep Packet Inspection (DPI, Deep Packet Inspection) devices. Background technique [0002] With the rapid growth of Internet business, the management and control based on various services is a concern of all links in the industry chain, but the first condition to realize the management and control based on various services is to identify the corresponding applications. Using DPI equipment is undoubtedly the best choice as a service identification function. [0003] DPI equipment has the ability of business data flow identification and business data flow control, works from the transport layer to the application layer of the Open System Interconnect (OSI, Open System Interconnect) model, has high data flow processing capabilities, and can perform services carried by the network Identification and traffic management are network devices that ca...

Problems solved by technology

[0004] In the current network deployment, multiple DPI devices, or other existing network devices integrated with DPI functions, are usually used for service identification and control. When multiple DPI devices are jointly used for service identification, detection and control, if one of If one DPI device fails, the identification of the traffic passing through the DPI device, that is, the business, cannot be completed, which will lead to subsequent processing errors. Therefore, it is urgent to conduct unified management and control of all DPI devices, so that each DPI device can be linked and coordinated.

However, due to the multi-level deployment of DPI equipment and the diversity of function implementation methods, it is difficult to realize the unified management and control of existing distributed deployment of DPI equipment.
