Problems solved by technology
This method does not consider the system interconnection and data exchange of multiple heterogeneous information of AOIS, and can only achieve a single local backup, and cannot form a systematic disaster recovery technology
In view of the above, although my country has made some achievements in the research of emergency response and disaster recovery of large-scale networks and information systems, the basic theory for AOIS information security is lacking, and the research on key technologies is not deep enough, especially in the case of AOIS disasters. In terms of recovery, there is a lack of reasonable implementation plans and effective methods

For the AOIS disaster recovery of the aviation airport operation information system, many existing methods do not consider the system interconnection and data exchange of AOIS's multi-heterogeneous information, and only achieve a single local backup, which cannot form a systematic disaster recovery technology. On the basis of studying the AOIS system structure and functional modules, the invention introduces a network coordination and elasticity mechanism to realize the disaster recovery technology of AOIS. The following two aspects are mainly studied: 1) A flexible disaster recovery strategy is proposed, and the technology of drift service is used to realize the rapid recovery of AOIS during system failures and security events, and to improve the efficiency of fault services; 2) When the nodes in AOIS When attacked, the heartbeat mechanism (Heartbeat) is introduced into HSAP (Hash-based Security Access Path) to monitor the health status of the entire AOIS routing platform node in real time. Trying to solve the problems of flight delays and cancellations caused by AOIS system failures and security incidents from a technical level to avoid unnecessary losses.
Description
Technical field: [0001] The invention relates to a computer network security technology, in particular to a disaster recovery method for an AOIS (Airpot Operational Information System) aviation airport operation information system, which can quickly restore business services and related data. technical background: [0002] Flight delays have become the focus of society. According to the "2014 National Civil Aviation Flight Operation Efficiency Report" released by the Civil Aviation Administration of China, the flight punctuality rate in 2014 was only 68.37%. There are many factors that cause flight delays. From a technical perspective, AOIS system failures and security incidents are one of the main factors leading to flight delays. Internationally, failures and security incidents of the aviation airport operation information system or the computer system involving the airport's air traffic management system occur from time to time, which lead to the interruption of flight op...
