Satellite networks can help extend wider communication coverage and provide more types of services; and introducing service function chain (SFC) to satellite networks can enhance their flexibility and scalability. However, this highly challenges the complexity and efficiency of network service management. In this work, we first present an intent-driven satellite network service management architecture. It provides a user-oriented programmable and customizable service provisioning mechanism, which can improve the flexibility and efficiency in service delivery and provisioning. Furthermore, we elaborate an intent-driven SFC deployment scheme, which is termed as ISFC. The presented ISFC is with the intent parsing, network function virtualization infrastructure point of presence selecting, and the optimal service function path generation. Finally, we provide the ISFC deployment algorithm. And the simulation results show that the presented ISFC scheme can well satisfy user’s requirements with much lower delay.
