Abstract

The invention discloses a spatial information network management and control method, which comprises the following steps: performing network initialization, including dividing a control plane and a data plane; configuring a control surface; the control plane sensing a service demand; the control panel pre-judging the network load condition; when the pre-judgment result is that the network load isbalanced, the network completing a data transmission task by adopting the traditional IP exchange, and then releasing data plane resources; and when the pre-judgment result is that the local overloadoccurs, the control plane generating a routing table entry based on a network control protocol of an SDN (Software Defined Network) technology, configuring a data plane according to the routing tableentry, the data plane executing a service, and the data plane releasing data plane resources after the service is executed.

Description

technical field

[0001] The invention relates to the technical field of satellite communication, in particular to an SDN-based space information network management and control method. Background technique

[0002] The space information network is a network system that acquires, transmits and processes space information in real time, based on space platforms (including high-orbit satellites, low-orbit satellites, stratospheric balloons or other aviation vehicles, etc.). As an important national information infrastructure, the spatial information network can serve major applications such as ocean navigation, emergency rescue, navigation and positioning, air transportation, and aerospace measurement and control. At present, relevant institutions and organizations at home and abroad have invested a lot of manpower and material resources in the research and experimental verification of spatial information network related technologies.
