Network service searching method based on P2P network double-layer ring-shaped routing structure

Abstract

The present invention discloses a network service searching method based on a P2P network double-layer ring-shaped routing structure, and belongs to the computer network service retrieval field. The present invention aims to resolve a technical problem that network service searching efficiency and accuracy are significantly reduced because a conventional searching manner is only limited to keyword matching. A used technical solution is: the method organizes network service registered nodes based on a double-layer ring-shaped routing structure P2P network, integrates with difference of node capabilities in an actual network, fully uses a dynamic mechanism of searching and positioning nodes in the P2P network, and clusters the registered nodes by using a service field ontology concept mapping range according to types of services provided by the registered nodes, so that network service registration and discovery of a specific field is concentrated on a small quantity of continuous nodes of an outer ring in the double-layer ring-shaped structure.

Description

technical field [0001] The invention relates to the field of computer network service retrieval, in particular to a network service search method based on a double-layer ring routing structure of a P2P network. Background technique [0002] The main function of network service search is to retrieve some functional services provided by the network. The traditional network search method uses a centralized architecture UDDI registration model for service search. With the rapid increase in the number of network services, the ever-increasing real-time requirements and the lack of necessary semantic information in service search descriptions, it is difficult to search and match in the search and match process. Using service functions as search elements leads to the traditional search method being limited to keyword matching, which greatly reduces the efficiency and accuracy of network service search.
