Abstract:The design of a service bus platform for cross-domain sharing of information technology data in the pan-government industry is proposed. The underlying hardware is designed based on one-way optical transmission to achieve secure isolated transmission of data between different network domains. The upper system software realizes cross-regional and cross-domain service authorization access, resource authorization invocation and data security forwarding through the ESB service bus architecture and the definition of a unified request invocation interface. The whole system is composed of request protocol conversion, security inspection and control components, health assessment, MQ data services, node resource scheduling, flow restriction and fuse management, channel task management, resource monitoring and reporting modules, which can realize request services, equipment status reporting, channel task management, security access control and other functions, and set different application modes according to different business levels. In short, the proposed platform can meet the safe and efficient transmission between data resources of cross-domain mobile police request services.
