SDN/NFV-enabled Satellite Communications: Ground Segment Network Architecture for 5G Integration
نویسندگان
چکیده
The satellite industry is clearly committed to revisit and revamp the role of satellite communications within the 5G ecosystem. Central technologies being adopted in 5G networks such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) are also anticipated to become key technological enablers for improved and more flexible hybridization of both satellite and terrestrial segments. This paper describes a novel architecture for SDN/NFV-enabled satellite ground segment systems that is conceived to facilitate the integration of the satellite component within 5G systems so that ubiquitous, highly available and reliable connectivity can be better supported. Keywords—Satellite network; Network Function Virtualization; Software-Defined Networking; Satellite gateway virtualization; Combined satellite-terrestrial networks

متن کامل5G-Crosshaul: An SDN/NFV control and data plane architecture for the 5G integrated Fronthaul/Backhaul
This paper presents the control and data plane architecture design for a 5G transport solution (5G-Crosshaul) with the aim of integrating the fronthaul and backhaul network segments in a common transport stratum. The control plane relies on the SDN/NFV concept to control and orchestrate the different elements of the network (the 5G-Crosshaul Control Infrastructure, XCI). The data plane is based...
