First, the 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. It is suitable for data gathering, data distribution, data exchange and sharing, etc. Large enterprises can use integration skills, on this basis, plan out data exchange channels and study the support of hierarchical services of data exchange channels for the use of the system, and determine the form of data exchange. The selection of the federal data exchange system channel and the use of virtual database method to solve the cross-channel and multi-data source data exchange, can fundamentally meet the data integration of various existing information systems.
Second, the system requirements
The federal data exchange system is mainly composed of three parts: data collection probe, AC operation center server, and assembly monitoring and management system (hereinafter referred to as the centralized control system), and the AC operation center server and data collection probe together form a 1:N data exchange structure.
The data collection probe and AC operation center server are products with integrated software and hardware, and have built-in national cryptography encryption chips and security operation systems. In the meantime, data collection probes can be divided into general type and barrier type. The barrier collection probe adopts the hardware architecture of dual host with barrier module, which meets the requirements of the domestic security management department for network barrier security products.
3. System depiction
Each participating communication node is equipped with a general collection probe or a blocking collection probe according to the actual needs. The data collection probe obtains incremental data from the pre-database or pre-processor, encrypts it through the built-in national cryptography encryption chip, and then packages it for transmission through the message rows and columns.
The exchange operation center is primarily responsible for the business handling, security management, operation monitoring and audit of the entire system. According to the actual needs, the customer can arrange the exchange operation center server or server cluster in the exchange center, and block it from the public communication network through the network gate. The federal data exchange system completes the code operations such as data encryption, data signature, and authentication through the national secret chip built into the probe and server hardware that meets the requirements of the national cipher code management department.
General collection probes:
In the federal data exchange system, each data collection probe is an exchange node. Generally, the collection probes go through various database adapters and can be connected to various databases of various units. The synchronization mechanism of the database itself is used to maintain the data synchronization between the internal production library and the front library of the exchange unit, and the probe can be connected to the front library to obtain data, or directly connected to the production library to obtain data.
Generally, the collection probe has various built-in adapters, including database adapters, file adapters, data flow adapters, usage system adapters, mail adapters, middleware adapters, etc.
Barrier Collection Probes:
The barrier collection probe is composed of two hosts, and a dedicated dual-channel barrier AC card between the two hosts is implemented.
The blocking AC card is the only channel for data exchange between the host of the surface and the back network. There is no operating system and 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 data in the surface and the network.
Fourth, the system block diagram
At this stage, EVOC industrial server products are mainly used in AC operation center servers.
