Towards SDN/NFV-enabled satellite ground segment systems: End-to-End Traffic Engineering use case
Key features of satellite communications such as wide-scale coverage, broadcast/multicast support and high availability, together with significant amounts of new satellite capacity coming online, anticipate new opportunities for satellite communications services as an integral part within upcoming 5G systems. To materialize these opportunities, satellite communications services have to be provisioned and operated in a more flexible, agile and cost-effective manner than done today. In this context, this paper firstly describes the architecture of a satellite ground segment system that builds on the introduction of Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies and then examines a use case for the realization of End-to-End Traffic Engineering in a combined terrestrial-satellite network used for mobile backhauling.
