Design and performances study of a self-configurable solution for future transport networks

Abstract :
In this thesis, we study the LOCARN solution “Low Opex & Capex Architecture for Resilient Networks". LOCARN is an alternative packet network architecture that has been conceived with a special attention to the simplicity of its structure and mechanisms while allowing by design the resiliency and the self-adaptation of clients transportation services.
Considering the growing complexification of operators transport networks during the last decades, we consider these latter as the privileged use case. In such a context, LOCARN would allow a drastical simplification of devices and their operation compared to common operator solutions – this involves respectively reductions of CAPEX and OPEX. In this work, we first present LOCARN technically and we bring out its interests for operators beside other transport technologies. Then, since the primary issue of LOCARN is it scalability for large networks, we study this point in details which allow us to establish that
the architecture is altogether capable to scale in realistics transport networks. Moreover, to increase the performances we specified two design improvements allowing the architecture to transport a huge amount of clients, the obtained results are very encouraging.
