Distributed index resources integration and sharing method across internal and external networks

Abstract

The invention discloses a distributed index resources integration and sharing method across internal and external networks. The method comprises the following three modules: a distributed storage module used for dividing data produced by the industry into different categories according to the specific requirements, registering the data and generating an index, and storing different categories of data on different physical nodes; a sharing module: data of the internal and external networks are distributed in different physical nodes of the same cluster, an internal network provides part or all information of index data for an external network platform by using a file ferrying way of a gatekeeper, and the external network provides requests for the internal network; and a distributed retrieval module used for performing distributed retrieval on different data indexes integrated on the external network in a concentrated way, and calling back to the internal network and acquiring detailed information according to a retrieval result. According to the distributed index resources integration and sharing method across the internal and external networks provided by the invention, a distributed indexing mechanism of different categories of data and a data sharing mechanism between internal and external network gatekeepers can be realized, based on a big data platform, large amounts of data can be processed in a near real-time distributed way, and the retrieval, sharing and other requirements of users can be satisfied.

Description

technical field [0001] The invention relates to information processing technology, in particular to a method for integrating and sharing distributed index resources across internal and external networks. Background technique [0002] Effective integration and timely sharing of data resources between internal and external networks and methods are technical bottlenecks that have attracted much attention in many industrial applications that focus on data and information security. In order to ensure data security, many industrial informatization applications use hardware devices such as physical isolation cards or security gates to divide the network into internal and external systems to achieve appropriate information isolation between networks. However, simple one-way data isolation often creates obstacles to specific business process practices. [0003] In the actual production process of various industries, for the convenience of project management, two different systems ar...
