An Agent-Based Synchronization Method of Information Resource Directory

Abstract

The invention discloses an agent-based information resource directory synchronization method, comprising: deploying an information resource directory node in each organization domain, and deploying a directory synchronization agent node on a gateway server of each organization domain; when the first organization domain When data changes occur in the information resource directory node, the operation message is sent to the directory synchronization agent node, and the directory synchronization agent node sends the synchronization message to the directory synchronization agent node of the second organization domain; when the directory synchronization agent node of the second organization domain receives When synchronizing messages, judge whether to synchronize with the first organization domain according to the synchronization message; if not, the directory synchronization proxy node of the second organization domain pulls the changed information resource metadata to update the information resource directory node. By adopting the above-mentioned method, it is possible to realize the direct synchronization of the information resource directory mesh, break through the bottleneck limitations of the synchronization server performance and load in the central synchronization method, and avoid the synchronization failure problem caused by the destruction of the synchronization server.

Description

technical field [0001] The invention relates to the technical field of information resource directory synchronization, in particular to an agent-based information resource directory synchronization method. Background technique [0002] The catalog of information resources is a group of information sorted and coded according to the standardized metadata description of resources in various fields and according to a certain classification method, which is used to describe the information characteristics of each resource and realize the registration, discovery, Sharing, retrieval and other capabilities. The catalog of information resources is currently widely used in government affairs, transportation, services and other fields. [0003] Information resource catalogs are generally distributed and deployed in different organizational domains according to hierarchical relationships. For example, an information resource catalog node is deployed in each organizational domain such a...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an agent-based information resource directory synchronization method to solve the problem that in the existing centralized information resource directory synchronization method, if there are too many information resource directory nodes, the load and traffic of the synchronization server will show a linear upward trend. Cause synchronization performance bottlenecks and decrease the timeliness of synchronization

If the central synchronization server goes down, the synchronization function of all information resource directory nodes will be unavailable, resulting in the problem that the resource directory synchronization method cannot be effectively and smoothly implemented
