Software Defined Networking (SDN) for Universal Access

Abstract

Ensuring Universal Access/Universal service to the populations of developing countries is up to now a big problem which can be explained by the fact that the telecommunication operators estimate certain areas unprofitable. The Universal access to the Technologies of Information and Communication being a non-discriminatory right for any citizen wherever he lives, different approaches are implemented to guarantee it. One of these approaches is to recourse on cheap equipment associated with innovating technologies. The aim of this article is to be able to study to what extent the Software Defined Networking could be a viable solution for the localities interested in Universal access. To reach this goal, we have been lead to study a typical Voice over IP traditional architecture and the architecture tooled with the Software Defined Networking technology.

When implemented the Software Defined Networking technology is supposed to guarantee a good quality of service. In our contribution we have set up a Voice over IP environment with Asterisk server as equipment of the network core, and affordable equipment such as the WIFI access points in the element entitled, ≪Collecting subscribers≫. The Quality of Service being our preoccupation, the comparison of all our results shows that the architectures with Software Defined Networking offer a better quality of services.
