Abstract

The embodiment of the invention discloses a rule matching method, a device and a system, wherein the rule matching method comprises the steps of: obtaining the characteristic of the matched data; determining the target state machine from a plurality of state machines according to the characteristic of the matched data; obtaining the plurality of state machines by compiling a plurality of sub-rulesets; obtaining the plurality of sub-rule sets according to the division of different characteristics of the rule; the characteristic of each sub-rule set is used for respectively identifying the state machine which corresponds to each sub-rule set; and carrying out the rule matching by matching an engine according to the target state machine. The embodiment of the invention effectively reduces the size of the rule set in the state machine and causes the branch of the state machine to reduce and the depth of the state to becomes small, thus being capable of reducing the matching period of therule matching and saving the cost and time of the system resources, and further increasing the matching efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a rule matching method, device and system. Background technique [0002] At present, the explosive development of IP (Internet Protocol, Internet Protocol) services and the rapid growth of broadband services have brought opportunities and also challenges to operators. DPI (Deep Packet Inspection) technology, as an enhanced filter for network equipment, organically integrates capabilities such as user management, security control, and fine service control. Realize the dynamic perception of various services, policy control, QoS (Quality of Service, service quality) and service security and other functions. It not only provides operators with a basic operation platform for telecom services, but also reduces the capital of operators. Expenditures and operating expenses. [0003] The key role of DPI technology is to identify the application category of data in...
