About this event

Abstract: Software Defined Networking (SDN) promises to bring unparalleled flexibility, configuration simplification and vendor lock-in removal. On the flip slide, the SDN logic centralization requires a global renovation of network equipments. Moreover, it raises issues, e.g. on network resiliency and reaction to failures, that have been effectively solved by traditional routing protocols. In this talk, we present ongoing work on hybrid SDN networks, where SDN and traditional paradigms coexist. We discuss how hybridization can help mitigating major concerns of SDN, focusing on a proposal to improve resilience and scalability of SDN, by using a distributed protocol as a backup routing mechanism. As such, hybrid SDN provides means and incentives to (partially) transition to SDN. We also highlight how it can represent an interesting network design point that combines the advantages of SDN and traditional paradigms.
