Construction Of A Multi-level Secure Network

Along with the computer network fast develops, three-layers-switch technology has already popularized. And network system has marched into the mature period. The widespread application of computer network has already had material effect to the development of economy, culture, education and technology. Many important resources and information are interrelated to network. But the serious network security problem also starts to highlight day by day.With the economic information center develops fast to multimedia and multiplex direction, a higher request is required to official business and service network about personnel, operation, management and service and so on. The obsolete network system and the equipment hardly withstand the load. The existing network system and the equipment are unable competent for the service demand which is increasing day and day. Therefore MIS Server Room of Sichuan Economical information network needs large update again. By adopting massive new technologies and equipment enhances the feedback speed of network and the applied server, raises the work efficiency.1. Exchanging Application Server: More powerful CPU, higher memory, more expeditious memory speed and more memory space are schemed, and even more safety new operating system are also needed.2. Emergency Recovery Mechanism: By constituting spare backup mechanism, the data of appliance serve will be resumed more expeditious and more efficient.3. Using Switch with Brand-new Network Basic Frame: Three-layers-meshwork switch with flexible routing, intelligent switching ability and enough big bandwidth are adopted.4. Network Security Construction: Including the security firewall, the security invaded detection system and related emergency processing, virus isolation and guard mechanism.5. Intelligent Network Management: The secure network management software on the server monitors all servers run states real-time. When the sever runs exceptionally, the error message would be reported through each way. On LAN, by the network management software and management server data sharing, the exceptional messages are managed synchronously from the first floor to the high-level.Through such whole reforms in network and services structure, the high performance, the key status, the end-to-end secure request and pronunciation using and so on of Sichuan economical network have sufficient guarantees.
