Service-Oriented Virtual Resource Management Framework for Satellite Network

Satellite network resources appear heterogeneous, distributed, autonomous, extended, and dynamic characteristics, making traditional satellite network resource management technologies cannot meet the increasing needs of a variety of services with significant differences in the characteristics. Therefore, the introduction of technology of virtual network resource management is to achieve service-oriented resource management and scheduling. The premise of realizing the virtual resource management is to establish the framework of resource management. For this purpose, this paper establishes a service- oriented virtual resource management framework. The structure adopts a hierarchical partition management mechanism, and the virtual network is divided into subnets by the LNMC (logical network management center) while its resources are mapped by the LRMC(logical resource management center) according to the restrictive conditions of service. The centralized management and distributed control system is designed to take into account the characteristics of high dynamics and large scale of topological space of satellite network, which can improve the efficiency of resource utilization and the quality of service.
