Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] see figure 1 Shown, the present invention is based on the approximate matching strategy of token set, comprises the approximate matching method based on token set, and method comprises:

[0018] Retrieve all token rules in the token set, filter the rules that can be effectively matched during data transmission, count the number of matches of the rule, and count the number of token matches at the same time; compare the number of token matches with the number of rule matches The weighted ...

Abstract

The invention discloses an approximate matching strategy based on a token set. Including the approximate matching method based on the token set, the method includes: retrieving all token rules in the token set, screening the rules that can be effectively matched during data transmission, counting the number of matches of the rule, and counting the number of token matches Number of times; weight the number of token matches and the number of rule matches, and put the feature value after rounding into the data after the token; count all feature values, and put all tokens in order from large to small according to the feature value Sorting; when receiving tokens, the host first filters the token set through rules, and then matches according to the order of characteristic values ​​from large to small. The present invention quickly filters the rules that cannot produce effective matching, and uses screening and sorting for pairwise matching of subsequent queries, and performs matching by referring to the highest-ranked matching based on frequency and the intersection of the results obtained by calculating the query and all rules, and more Efficient.

Description

technical field [0001] The invention belongs to the field of network technology, in particular to an approximate matching strategy based on a token set. Background technique [0002] The token is a special frame transmitted on the token ring. The token is 24 bits long and has three 8-bit fields, which are the first delimiter (Start Delimiter, SD), access control (Access Control, AC ) and the end delimiter (End Delimiter, ED) The first delimiter is a distinctive signal pattern, which is expressed as a non-data signal, and the purpose is to prevent it from being interpreted as something else. This unique 8-bit combination can only be identified as a Start of Frame Identifier (SOF). The medium access control mechanism of the token ring network adopts the circulation method of the distributed control mode. In the token ring network, there is a token (Token) which is passed along the ring bus between the network node computers in turn. The token is actually a frame in a special...
