Virtual network mapping method based on space-ground integrated information network

Abstract

The invention discloses a virtual network mapping method based on a space-ground integrated information network, and the method comprises the steps: carrying out the business classification of virtual network requests under the space-ground integrated network, and combining the business characteristics with the mapping priority of the virtual network requests on the basis of the business classification; and carrying out personalized scheduling on the mapping sequence of the virtual network requests. And in the virtual network mapping physical node selection process, considering the residual quantity of resources of the physical nodes and the proximity centrality of the physical nodes in the whole network, and sorting the nodes according to the calculated resource coupling. The invention aims to improve the problem of resource fragmentation and guarantee the mapping time delay requirement of a virtual network request, so that the mapping energy consumption is reduced, the resources are efficiently utilized, and the income of an infrastructure provider is improved.

Description

technical field [0001] The invention belongs to the field of information network virtualization of the integration of space and earth, and in particular relates to a virtual network mapping method based on the integration of space and earth information network. Background technique [0002] The space-earth integrated information network is a multi-dimensional heterogeneous network composed of a multi-layer network architecture. Its main body is mainly based on the traditional terrestrial network and the space-based satellite network as a further supplement. It can provide users with more comprehensive and reliable network services. Through the deep integration of multi-dimensional and multi-level networks, the integrated information network of space and earth can effectively and comprehensively utilize various resources, break the bottleneck that each layer of networks is independent of each other and cannot share information, and achieve wide-area full coverage and all leve...
