Distributing connectivity management in Cloud-Edge infrastructures using SDN-based approaches

Abstract : The evolution of the cloud computing paradigm in the last decade has amplified the access of on-demand services (economical attractive, easy-to-use manner, etc.). However, the current model built upon a few large datacenters (DC) may not be suited to guarantee the needs of new use cases, no-tably the boom of the Internet of Things (IoT). To better respond to the new requirements (in terms of delay, traffic, etc.), compute and storage resources should be deployed closer to the end-user. In the case of telecommunication operators, the network Point of Presence (PoP), which they have always operated, can be inexpensively extended to host these resources. The question is then how to manage such a massively Distributed Cloud Infrastructure (DCI) to provide end-users the same services that made the current cloud computing model so successful. In this thesis realized in an industrial context with Orange Labs, we study the inter-site connectivity management issue in DCIs leveraging the Software Defined Networking (SDN) principles. More in detail, we analyze the problems and limitations related to centralized management, and then, we investigate the challenges related to distributed connectivity management in DCIs. We provide an analysis of major SDN controllers indicating whether they are able or not to answer the DCI challenges in their respective contexts. Based on this detailed study, which is a first contribution on its own, we propose the DIMINET solution, a service in charge of providing on-demand connectivity for multiple sites. DIMINET leverages a logically and physically distributed architecture where instances collaborate on-demand and with minimal traffic exchange to provide inter-site connectivity management. The lessons learned during this study allows usto propose the premises of a generalization in order to be able to distribute in a non-intrusive manner anservice in a DCI.
