With the development of new satellite payload technology, in order to improve the utilization of system resources, research is based on software-defined network (SDN) and network function virtualization (NFV) gateway architecture. Based on this architecture, the system realizes global resource management and overall data distribution, which can solve the problem of resource allocation and maximum/minimum rate guarantee between different VNO terminals under different beams, different gateways, and different satellites. For this, a global bandwidth management method can be used which is mainly a process of management to control the traffic on a communication link. The proposed global resource management and control method can be based on the rate guarantee value of the VNO/terminal configured in the system as the basic limiting condition and reallocate the rate guarantee value limiting parameter according to the resource application status of the online terminal. The method can maximize the resource utilization of the entire satellite communication system and satisfy the resource request of the user terminal as much as possible.

“…The authors in [30] studied the SFC deployment problem to minimize the service end-to-end delay in satellite networks. In a multidomain NFV-enabled satellite-terrestrial networks, the authors in [31] proposed a horizontal-based multi-domain SFC orchestration to improve the service end-to-end delay. However, the related work just discussed the VNF placement problem on behalf of either the users or the service providers.…”

“…Compared with the static routing method, the service cost and end-to-end delay are significantly reduced, but the solution efficiency for large-scale scenarios needs to be improved. Li et al [16] proposed a horizontal-based orchestration scheme for multi-domain SFC in SDN-/NFVenabled satellite-terrestrial network, and using multi-domain controller to coordinate the SFC orchestration problem, whose main contribution is the focus on the coordinate method between master multi-domain orchestrator and intra-domain orchestrator. e SFC deployment scheme of above works did well in their aspects, but most of them rely on accurate states observation.…”

The aim of this study was to reduce the influence of highly dynamic substrate network topology and large transmission delay caused by long communication distance between satellites and ground in Software Defined Satellite Networks (SDSNs), and a Partial Observation Markov Decision Process (POMDP)-based service function chain (SFC) deployment scheme of SDSN is proposed. Under this SDSN architecture, the network topology changes could be obtained through the SDN centralized control ability. Due to the topology changes, which may cause inevitable observation errors and transmission delays, the complete actual topology and network states cannot be obtained in real time. Thus, we put forward a POMDP model–based SFC deployment scheme, and an approximate iterative algorithm to solve the problem, aiming at optimizing the end-to-end network delay in the SDSN. The simulation results show that our model can optimize the delay of SFC deployment process, and improve the resource utilization and network throughput of the SDSN.
