The paper entitled as SDN/NFV-enabled satellite communications networks: Opportunities, scenarios and challenges published online at Elsevier Phycom Journal with DOI doi:10.1016/j.phycom.2015.10.007.
The paper focuses in the context of next generation 5G networks, where the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and more flexible integration of satellite and terrestrial segments, providing satellite network further service innovation and business agility by advanced network resources management techniques.
Through the analysis of scenarios and use cases, in this paper a description of the benefits that SDN/NFV technologies can bring into satellite communications towards 5G is provided. Three scenarios are presented and analysed to delineate different potential improvement areas pursued through the introduction of SDN/NFV technologies in the satellite ground segment domain. Within each scenario, a number of use cases are developed to gain further insight into specific capabilities and to identify the technical challenges stemming from them.
