Task-driven reconfigurable spatial information network resource management framework 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. The control management ability of a plurality of non-shared ground stations is centralized, and a network reconfiguration controller with overall dynamic control ability is constructed in a control center. A reconfigurable resource management framework is constructed through effective coordination of a task control center, a ground control link and an air control link. A control command is generated in real time bythe reconfiguration controller and transferred to a switch through an optical fiber link and a satellite-ground link. An application layer obtains various task input, and realizes task generation. Acontrol layer realizes unified planning of tasks in the whole network and unified scheduling of resources. A resource layer forms a resource pool using a resource virtualization technology, and provides a transmission channel. The invention provides theoretical support and technical guarantee for the task-driven spatial information network in the future, and plays a leading and promoting role in the research and development of the spatial information network in the future.

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
