Web service finding method based on balanced binary tree Chord network architecture

Abstract

The invention discloses a web service finding method based on balanced binary tree Chord network architecture, and the method is used for solving the corresponding service finding problem in a mixing mode and implementing a solution for semantic Web service finding through a provided Enhanced-AVLTree and Chord structure mixed architecture. A network model is divided into two layers; an upper layer is grouped by aiming at the classification of a semantic domain to which a service type belongs, and a corresponding service classification grouping node tree model is constructed by using Enhanced-AVLTree; a lower layer constructs resource publishing and implementation of the service of the classification by using the Chord structure, and the semantic domain to which a service belongs is quickly positioned under the condition of guaranteeing O(logn) by the Enhanced-AVLTree structure; a peer-to-peer (P2P) network is constructed in a manner of combining Enhanced-AVLTree and Chord, so that balance of a network load is facilitated, and the defect of non-uniform load of the conventional network is overcome; and due to the semantic Web, the query positioning result is relatively accurate.

Description

technical field [0001] The invention is mainly oriented to the problem of rapid release and discovery of large-scale semantic Web services, and in particular relates to a method for discovering Web services based on a balanced binary tree Chord network structure. Background technique [0002] In service computing, Web service is a concrete manifestation and functional carrier of the service concept. It is an application program based on the Web environment that is self-adaptive, self-describing, modular and has good interoperability. As a new distributed component model, Web service has played an increasingly important role in e-commerce, enterprise application integration and other fields. With the increase of the number and types of Web services in the Internet, how to discover services conveniently and effectively is one of the key issues to be solved by service-oriented architecture SOA. In recent years, scholars at home and abroad have devoted themselves to semantic-ba...
