A task-driven reconfigurable spatial information network resource management architecture and method

Abstract

The invention belongs to the technical field of spatial information, and discloses a task-driven, reconfigurable spatial information network resource management framework and method, which centralizes the control and management capabilities of a plurality of ground stations that are not shared, and builds a control center with global dynamic management and control capabilities. A capable network reconfiguration controller; through the effective cooperation of the mission control center, the ground control link and the air control link, a reconfigurable resource management architecture is constructed; the control commands are generated in real time by the reconfiguration controller and sent through the fiber link The road and satellite-ground link are passed to the switch. The application layer obtains various task inputs and realizes the generation of tasks; the control layer realizes the unified planning of the whole network tasks and the unified scheduling of resources; the resource layer uses the resource virtualization technology to form a resource pool and provide transmission channels at the same time. The invention provides theoretical support and technical support for the future task-driven space information network, and plays a leading and promoting role in the research and development of the future space information network.

Description

technical field [0001] The invention belongs to the technical field of spatial information, and in particular relates to a task-driven reconfigurable spatial information network resource management framework and method. Background technique [0002] The space information network is a network system that uses space platforms (high, medium and low orbit satellites, stratospheric balloons, spacecraft, etc.) Air transportation, aerospace measurement and control and other major application requirements, so as to expand human science, culture, and production activities to space, ocean, and even deep space. Its development process has gone through the process from isolation and closure to interconnection, from the early satellite ground measurement and control network with ground measurement and control stations as the backbone network to the space-based network, and finally to an open, interconnected, and interoperable space information network. However, due to the diverse types ...

AI Technical Summary

Problems solved by technology

[0004] For the research on the design method of spatial information network resource management architecture, the problems existing in the existing technology are: the functions of conventional spatial nodes in the current spatial information network architecture are relatively fixed, usually work in a specific mode, and cannot be reconfigured, and the node control plane and The data plane is difficult to separate, and only simple and quasi-static control methods can be used
