An all-optical spatial information network allowing dynamic linking and information transmitting devices of the all-optical spatial information network are applied to the field of space communication. To solve technical problems of an existing spatial information network, the all-optical spatial information network is structurally composed of a plurality of nodes, each node is provided with an information transmitting device, an information receiving device and a target scanning and tracking device, and the scanning angle of each node is theta; according to the nodes, when the first node is in communication with the second node, the first node finds the second nodes through the corresponding target scanning and tracking device and then transmits information to the information receiving device of the second node through the corresponding information transmitting device; meanwhile, the first node finds the third node within the scanning angle theta through the target scanning and tracking device and then transmits communication information to the third node, and the third node transmits the information to the information receiving device of the second node through the corresponding information transmitting device; the first node, the second node, the third node, the four node and the like form the all-optical information communication network.

The present disclosure provides a load balancing method and device for a multi-control storage system. The backplane is used to package multiple ports to connect each controller, so that each controller can realize fast information transmission through the lines inside the backplane, and each controller can obtain the status of other controllers in real time. Designate the owning controller for each logical volume and use the internal information transmission channel of the backplane to synchronize the ownership information among the various controllers. When one of the controllers receives a data read and write request for a logical volume from the client, it determines the ownership controller of the logical volume through the ownership information, and hands over the business to the corresponding ownership controller. Data access can thereby be efficiently performed using a plurality of controllers.

The invention discloses a space multi-node laser self-organized network communication system, and belongs to the technical field of the wireless laser communication and network. The problem existing in the traditional space laser communication networking system is solved. The system is composed of six nodes, each of the first node and the sixth node is composed of an optical transmitting / receivingmodule, a gigabit network switch, a group of large-field laser transmitting lens group and a group of optical receiving lens group; each of other nodes is composed of two optical transmitting / receiving modules, one gigabit network switch, two groups of large-field laser transmitting lens group and two groups of optical receiving lens group; the gigabit network switch in each node is connected with the optical transmitting / receiving modules; and the optical transmitting / receiving modules are respectively connected with the large-field laser transmitting lens group and the optical receiving lens group; various nodes are mutually connected through the corresponding large-field laser transmitting lens groups and the optical receiving lens groups; the data transmission among any nodes in the self-organized network system is realized; the space multi-node laser self-organized network communication can be realized, and the system is suitable for the data chain transmission in the future intelligent internet of things.

The invention relates to coverage enhancement technology in the field of satellite communication, and discloses an information transmission method based on a stratospheric quasi-static satellite base station, which comprises steps: (1) the stratospheric quasi-static satellite base station is formed by a stratospheric floating system, a communication load system and an operation control system, has small movement relatively to the ground, and can be deployed according to needs over a region with a satellite signal coverage enhancement requirement for providing long-time stable transparent forwarding or communication forwarding treatment service for various satellite users; and (2) the stratospheric quasi-static satellite base station distributes communication resources according to user types and service types, provides in-base station transmission service for communication between users in the current base station coverage region, provides inter-base station transmission service for communication outside the base station coverage region, signals are relayed and transmitted by the satellite via the base station, and subsequent communication transmission is completed via the satellite. Space and cost advantages of the stratospheric quasi-static satellite base station are used for providing convenient and high-efficiency coverage enhancement ability for satellite communication.
