SDN-based Service-Driven Virtualization Scheme

In1 order to solve the problem of the resource allocation rigidity that traditional network applications will appear in the space-ground integrated network, this paper proposes to use network virtualization technology in the integrated network architecture, and adopt a layered approach to provide cross-systems for end users of all services. The service avoids the differences in the transmission and exchange layers between various types of business systems in the world. A business-driven resource network virtualization solution was also proposed. A network virtualization layer was added between the control layer and the data forwarding layer. Resource isolation enabled flexible management and configuration of resources.
