The application discloses an address switching method, device, system, storage medium and electronic equipment. It relates to the technical field of communication and can be used in the field of financial technology or other fields. The method comprises the following steps: receiving a switching script from a control server, wherein the switching script is used to instruct a first server to perform address switching with a second server by initiating a preset command and performing a preset operation, the initiator of the preset command determines whether the receiver of the preset command performs the preset operation according to whether a response to the preset command is received, and the preset operation is used to indicate that the response to the preset command is stopped; and performing address switching with the second server according to the switching script. Through the application, the problem that the switching efficiency is low and the switching cost is high due to the use of an intermediate temporary IP and the control of the single pair of servers to complete IP switching by a control node in the related art is solved.

The invention discloses a working method and system of a quantum security firewall based on IP switching, and the method comprises the steps: the quantum security firewall creates n virtual interfaces with a corresponding number, and distributes a group of IP addresses for each virtual interface; selecting a part of virtual interfaces as virtual interfaces for communication; the remaining virtual interfaces are used as standby virtual interfaces; the quantum key service device distributes symmetrical key files for the extranet device and the quantum security firewall in the extranet device cluster; and the external network device of the data to be transmitted generates transmission data and sends the transmission data to the corresponding virtual interface, and the quantum security firewall judges whether to switch the virtual interface based on the received transmission data. According to the invention, through an IP switching mechanism, the service corresponding to the attacked IP can be seamlessly switched to other normally running virtual interfaces in real time for transmission and processing, the continuity and availability of the service are ensured, and the risk of service interruption caused by attack is greatly reduced.

The invention relates to the technical field of databases, and particularly provides a dynamic balancing method, system and equipment for database instances and a storage medium, and the method comprises the following steps: confirming that the health state of a current instance is abnormal, creating a new instance, and carrying out data synchronization between the current instance and the new instance; closing disaster recovery monitoring on the current instance and the new instance during the dynamic IP switching period; unloading the dynamic IP to be switched from the user network card of the current instance, and synchronously deleting the dynamic IP from the available address pair data of the user network card; and adding the dynamic IP to available address pair data of the user network card of the new instance, and controlling the user network card of the new instance to mount the dynamic IP by using a network management tool. According to the invention, automatic management of the cloud database and switching of the dynamic IP can be realized, the service continuity in a load balancing scene is ensured, and the misoperation risk of manual configuration of the dynamic IP is reduced at the same time.

The application provides a signal agile replacement method for an IP system boundary, which comprises the following steps: when a main end-stage signal processing device is determined to be abnormal by a multicast control system, the main end-stage signal processing device is configured synchronously to a backup end-stage signal processing device; the multicast control system controls a core IP switching matrix to close an interface connected to the main end-stage signal processing device; the multicast control system changes an upstream interface to an interface connected to the backup end-stage signal processing device; and the upstream interface is located in a multicast routing table of the core IP switching matrix. According to the method provided by the application, when the main end-stage signal processing device is abnormal, the upstream interface of the core IP switching matrix is changed to the interface connected to the backup end-stage signal processing device, so that the multicast is replaced quickly, and the emergency processing efficiency is improved.

The invention provides a DNS (Domain Name Server) management system and method and electronic equipment, and the system comprises a metadata definition module which is used for obtaining a hierarchical relationship configured by a user, and generating a domain name template; the domain name management module is used for receiving a to-be-analyzed domain name newly added by a user, and generating a domain name analysis record for the to-be-analyzed domain name based on a domain name template; the DNS equipment management module is used for maintaining a DNS server; the IP switching strategy module is used for generating an IP switching strategy and configuring a corresponding domain name according to the IP switching strategy; and the domain name authority management module is used for distributing authority to the user according to the domain name resolution record.
