Abstract

The invention discloses a multi-dimensional searching method for rules. The method comprises the following steps of: creating a rule array consisting of all the rules; taking each matching item of therule as a search dimension, respectively constructing a search structure corresponding to each search dimension of all the rules, constructing an index structure of the rule array, and associating the search structure with the index structure; when rule matching is carried out, searching a search structure corresponding to each search dimension so as to respectively obtain tree nodes or array items matched with each data item of the to-be-matched data from each search structure; and based on the association relationship between the tree node or the array item in the search structure and the index structure, respectively determining a rule matched with each data item of the to-be-matched data. The invention further discloses a rule multi-dimensional searching device and equipment and a computer readable storage medium. According to the method, on the premise that the search performance is prevented from being greatly reduced, the matched rules can be quickly obtained from mass rules through one-time search.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a regular multi-dimensional search method, device, equipment and computer-readable storage medium. Background technique [0002] In the field of data processing technology, it is usually necessary to search for corresponding matching rules to process data. For example, packets need to match corresponding routing rules before they can be forwarded. If there are multiple data items in the data to be matched, multiple matchings are required. That is, it is not possible to obtain all rules matching all data items through one search. In addition, existing rule matching algorithms are usually only suitable for a small number of rules. If tens of thousands of rules are matched, the performance will plummet as the number of rules increases. Contents of the invention [0003] The main purpose of the present invention is to provide a rule multi-dimensional search method,...
