Resource Scheduling Method, System and Application of Spatial Information Network Links

Abstract

The present invention relates to a resource scheduling method, system and application of a space information network link, wherein the resource scheduling method includes: S1, the data center classifies the data according to the data type; the data center uses static bandwidth allocation for periodic services The data transmission service data adopts the dynamic bandwidth allocation method, and the data center dynamically allocates the corresponding time slot for the data transmission service to be sent according to the node's request; the emergency service data is processed with high priority, and the In the static bandwidth allocation stage, the high-priority emergency business data is reserved for time slots, and in the dynamic bandwidth allocation phase, the high-priority emergency business data is preemptively allocated; S2, through the allocated time slots Sending the service data to the corresponding node; S3, receiving the feedback status frame fed back by the corresponding node after receiving the service database. The invention effectively improves the resource utilization rate of the information network and improves the network throughput.

Description

technical field [0001] The invention relates to the technical field of spatial information network, in particular to a resource scheduling method, system and application of a spatial information network link. Background technique [0002] As an important infrastructure of the country, the space information network can serve many fields such as ocean navigation, emergency rescue, navigation and positioning, air transportation, and aerospace measurement and control. However, the dynamic changes of the space information network network system and the frequent connection / interruption of communication links make the available network bandwidth and service quality of the network change at different times, and the requirements for the information transmission bandwidth of various aircraft are also different. Similarly, for example, giving priority to space information operations in wartime can improve the real-time and effectiveness of operations; giving priority to emergency event...

Problems solved by technology

However, these schemes are only aimed at the bandwidth allocation problem of the ground access network, without considering the characteristics of the space information network, and are not suitable for the resource scheduling of the space information network, and there are no relevant literatures on the resource scheduling strategy and related schemes for the space information network to report

[0004] A prior art proposes a hybrid access network resource scheduling method, device, and system. Due to the dynamics, heterogeneity, and scalability of spatial information networks, this solution cannot effectively schedule spatial information network resources; Another existing technology proposes a network resource scheduling method based on user experience. This method obtains user initial scheduling data according to user request resources and user grades, and statically allocates network resources to users according to user initial scheduling data. The resource The scheduling system is aimed at the ground network system, which cannot meet the characteristics of the space information network, and cannot effectively realize the resource scheduling of the space information network, and the resource scheduling strategy for the characteristics of the space information network has not been reported in the existing schemes
