Software-defined satellite cloud RAN

Résumé

This paper provides a feasibility study on the virtualization of a DVB-S2/DVB-RCS2 satellite ground infrastructure and its SDN-based management and control. The proposed framework, SatCloudRAN, is expected to increase the opportunities of smoothly integrating the satellite components in forthcoming 5G systems. We analyze the design of SatCloudRAN by considering various chaining of virtual and physical functions and the characteristics of the links between them. We based our analysis on a generic architecture of bidirectional access networks that follows the normative documents of the broadband forum and leverage virtualization and softwarization technologies, namely NFV and SDN, to achieve a flexible and programmable control and management of satellite infrastructure. Using a SatCloudRAN approach, network operators will be able to provide: (1) optimized dynamic QoS, (2) resilient management of multiple satellite gateways, and (3) dynamic bandwidth on demand.
