Disaster Armed Police Command Automation System Design And Implementation

With the rapid development of modern information technology, the computer hasbeen widely used in various fields, including modern national defense, military,government agencies, enterprises, greatly increasing the processing and storagecapability of information. This trend is the demand of the times, but it also gives rise tocertain important problems. Especially, information and data are stored in a hardwaredevice. Once lost or damaged, the enterprise may suffer incalculable losses. Thus, howto minimize the loss against large-scale disaster events becomes an important issuepeople care about, and is a matter of study on application of military command.So far, established for large-scale Data Center disaster recovery system is a secureand reliable military agreed on the most efficient and most feasible solution.Chinawenchuan earthquake of may12,2008is people will never heal wounds, local banksenormous natural disasters will move to the ground, leading to paralyze Server dataacross the worst-hit loss of information, bringing great harm to the government and themasses. Take measures to protect against disasters, the development of disastertolerance technology in the military is also imperative. Based on the paramilitary armedpolice force automation command of the three-level network design andimplementation of disaster recovery systems are meeting the needs of development ofthe military command, aim at high efficiency, low prices, in the development of armedpolice on three-level network platform.Design of automatic Armed Police Command disaster recovery system consists offour subsystems: firewall subsystem, security, transport subsystem, the localsynchronous mirroring subsystem subsystem and the remote mirror.The entire systemby establishing a synchronous mirror on a local system, use the Internet to a remote datacenter backup data to complete the implementation of disaster recovery technology.Through armed police of the three-tier network based remote mirroring system, forWhen disaster comes to destroying the local server, the server is up and running quicklyin another place, take responsibility services, to synchronize the data quickly betweenthe two places, increased service switching function for the system reduces themaximum amount of data transferred between the two places, ensuring the continuity ofthe service. This subject will be seamless integration of sophisticated firewall technology indisaster-tolerant system, enabling packet filtering, intrusion detection features such aseffective in preventing malicious attacks from hackers; produce data encryption anddecryption technology used in cryptography to ensure the security of data transmissionover the Internet; Make use of digital watermarking recording technique, strict RecordsManagement System log so that the Administrator has a full and resistance to denial of.At present, automatic Armed Police Command Disaster Tolerant system based onarmed police the three-tier network has passed simulation tests, and put into practicalapplications. The results shows the system achieves the desired goals with highpromotional value.
