Publish-subscribe matching method based on demand management tree model

Abstract

The invention discloses a publish-subscribe matching method based on a demand management tree model, the method comprises the following contents: 1, customizing a content label specification of an information product, and processing newly produced information products through the content label specification; 2, building a center directory database based on the demand management tree model, and summarizing subscription demands of all users; 3, realizing inquiry to the center directory database through content labels, and acquiring a to-be-sent subscriber list. The method provided by the invention provides a concentrated publish-subscribe implementation thinking and can easily implement management and user subscription of massive published themes, and processing modes are manageable, controllable and expandable. Compared with a conventional relational database, the method provided by the invention improves access efficiency of one order of magnitude and realizes effective consideration of both matching complexity and matching efficiency. A unified content label specification provided by the method can be used for unified management of various information based on content, and the method has better standardized generalization conditions.

Description

technical field [0001] The invention relates to a publish-subscribe matching method based on a demand management tree model. Background technique [0002] As a flexible event-based communication paradigm, the publish / subscribe system realizes the complete decoupling of the communication parties in terms of time, space and synchronization, and meets the communication needs of large-scale distributed systems. Among them, the content-based publish / subscribe system is a technological development trend, which is widely used in content distribution, information filtering, e-commerce and online games and other fields. Therefore, whether the matching method is content-oriented, flexible and fast is the most important thing in the design or selection of the publish / subscribe system. At present, there are three common publish / subscribe matching methods: central configuration file matching method, central relational database matching method, and distributed configuration file matching...
