The Application of EVOC Industrial Server Products in the Federal Data Exchange System
First, system overview
The Federal Data Exchange System is mainly used for distributed data exchange in wide area networks, metropolitan area networks, and e-government networks. Applicable to data aggregation, data distribution, data exchange and sharing applications. Each large-scale enterprise can apply integration technology and design a data exchange platform and research data exchange platform to support the application system based on the layered services and determine the data exchange mode. Utilizing the Federal Data Exchange System platform and using virtual databases to solve the data exchange between multiple data sources across multiple platforms can basically satisfy the data integration of various existing information systems.
Second, the system requirements
The Federal Data Exchange System is mainly composed of three parts: data acquisition probes, exchange operation center servers, centralized monitoring and management system (hereinafter referred to as centralized control system). The exchange operation center server and data acquisition probes together form 1:N data. Exchange structure.
The data acquisition probe and the exchange operation center server are integrated software and hardware products, and are equipped with a secret encryption chip and a secure operating system. The data acquisition probes can be divided into ordinary type and isolated type. The isolation probe uses a dual-host isolation-module hardware architecture that meets the requirements of the domestic security management department for network-isolated security products.
Third, the system description
Each participating switching node configures common acquisition probes or isolated collection probes according to actual needs. The data acquisition probe acquires incremental data from the front-end library or front-end processor, encrypts it through the built-in secret encryption chip, and packages it through the message queue for transmission.
The exchange operation center is mainly responsible for service management, security management, operation monitoring and auditing of the entire system. According to actual needs, customers can deploy switching operation center servers or server clusters in the switching center, and be isolated from the public communication network through the gatekeeper. The federated data exchange system completes cryptographic operations such as data encryption, data signature, and authentication through the built-in state secret chip that meets the requirements of the national password management department built into the probe and server hardware.
Ordinary acquisition probe:
In a federated data exchange system, each data acquisition probe is a switching node. Ordinary acquisition probes can be connected to various databases of each unit through various database adapters. Use the database's own synchronization mechanism to maintain data synchronization between the internal production database and the front-end database of the exchange unit. The probe can connect to the front library to obtain data, and can also directly connect to the production database to obtain data.
Common acquisition probes include various adapters, including database adapters, file adapters, data stream adapters, application system adapters, mail adapters, and middleware adapters.
Isolation probes:
Isolation probes are composed of two internal and external hosts, and a universal dedicated dual-channel isolated switch card is implemented between the two hosts.
Isolated switch cards are the only channels for data exchange between internal and external hosts. There is no operating system and application programming interface, and all the control logic and transmission logic are solidified in the security chip. It can independently realize the exchange and verification of internal and external network data.
Fourth, the system block diagram
At this stage, EVOC industrial server products are mainly applied in the exchange operation center server.
