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. Copyright
