Method and equipment used for inquiring, increasing, updating or deleting information processing rules

Abstract

The invention aims at providing a scheme used for inquiring information processing rules and realized through network equipment. The scheme comprises the steps of obtaining at least one identifying information from the network transmission information to be processed; and conducting the following steps according to each obtained identifying information : conducting digital signature processing on the identifying information so as to obtain one or more query index information of the identifying information, and inquiring in the index rule base related to the one or more query index information so as to obtain the information processing rule contained in the index rule base and matched with the network transmission information. In addition, the scheme also comprises the scheme used for increasing, deleting and updating the rules and realized through network equipment. The scheme can greatly improve the efficiency for inquiring, increasing, updating or deleting the rules.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for querying, adding, updating or deleting information processing rules. Background technique [0002] In many network environments, network transmission information needs to be processed according to corresponding information processing rules. In the prior art, network devices usually implement addition, deletion and query of information processing rules in the following ways: [0003] 1) Realized by hardware. In this way, configuration and query of information processing rules are realized by putting information processing rules into TCAM (Tri-State Content Addressable Memory). [0004] 2) Realized by software. This method puts information processing rules into memory, and uses complex algorithms to organize information processing rules. [0005] However, using the above method to configure and update information processing rules is often very complicat...

AI Technical Summary

Problems solved by technology

[0005] However, using the above methods to configure and update information processing rules is often very complicated, especially when the number of information processing rules is large, for example, when it reaches hundreds of thousands of levels, the efficiency of adding and deleting information processing rules is very low , and the way of hardware implementation will also generate higher cost
