The present invention discloses a method for continuously establishing an intersatellite link supporting the orbital maneuver of the BeiDou-3 satellite. The method uses the post-control theoretical orbit to assist in link building, so that the intersatellite link can operate stably and reliably. First, the intersatellite link topology routing of the satellite is planned, and an intersatellite link building plan is formulated. Then, before the orbital maneuver, two sets of satellite almanac parameters for the entire network are generated and the almanac parameters are added to the satellite. Then, the almanac link building is immediately enabled, and finally the orbital maneuver is implemented, so that the intersatellite link remains continuous. The method for continuously establishing an intersatellite link of the present invention is completely based on the satellite design state, and the processing flow can be automated. It can improve the intersatellite link of the orbital maneuvering satellite from being interrupted for K hours to being continuously uninterrupted throughout the whole process, and provides a technical guarantee for improving the service availability of the navigation system.

Embodiments of the present disclosure relate to a connection management method and device of a service node cluster, and a medium, wherein the method comprises: if it is detected that a first service node in the service node cluster meets a migration trigger condition, determining a second service node from idle service nodes in the service node cluster, and controlling the first service node to acquire a migration lock corresponding to the service node cluster, wherein the migration lock is acquired by one service node at the same time; in response to the first service node successfully acquiring the migration lock, controlling the second service node to acquire connection state information of a transmission control protocol of the first service node, adding a transmission control protocol connection in a local connection pool according to the connection state information; and modifying the first service node in a routing rule of the service node cluster to the second service node, so as to migrate an access request of a client to the first service node to the second service node based on the routing rule and the transmission control protocol connection. The service availability is improved.

This invention discloses a method for collaborative startup, state synchronization, and anomaly recovery of a desktop intelligent agent system, belonging to the field of desktop software operation control technology. The method includes: a launcher process creating a named mutex and detecting the existence of an already running instance; activating the already running instance and terminating the current instance if one exists; and loading a local configuration file and verifying the integrity of key fields if no running instance exists.
