End-to-end network slicing for future wireless in multi-region cloud platforms

End-to-end network slicing is an auspicious paradigm, which promises to lead the way towards efficiently addressing the problems of legacy networks. Based on softwarization and virtualization, it is capable of enabling network as a service (NaaS) and allowing the coexistence of multiple networks on the same physical infrastructure. These features make network slicing suitable for 5G by fostering the defined service performance and key performance indicators (KPIs). In this paper, we propose and implement an end-to-end slicing solution for multiregion cloud platforms. This solution leverages enablers like SDN and NFV and works in conjunction with our wireless testbed featuring fully virtualized and programmable systems that can be suitably installed and packaged for agile deployment. We conducted experiments to evaluate the performance regarding important KPIs such as: deployment time, management and reconfiguration, latency, and QoS characteristics. We present evaluations to validate the proposed slicing model and demonstrate its applicability for future wireless systems.
