Software Defined Networking is deemed a promising approach to enhancing network manageability, automation, and performance. Yet, despite extensive efforts, Internet-wide SDN deployment has been mostly stagnant, with only few networking players using it in specific centralized environments such as datacenter networks. Indeed, realizing SDN across different domains is a much more difficult, yet crucial, task, mostly because multiple independent Internet entities have to reach a consensus on how to inter-operate an SDN -based network. In this talk, I will present my recent efforts towards a better Internet-wide connectivity ecosystem. First, I will explore the possibility of improving end-to-end inter-domain connectivity between users, devices, and services through SDN federated networks. Second, I will discuss the orthogonal aspect of SDN compatibility with legacy network devices, including approaches to handling the interaction with traditional protocols such as the Address Resolution Protocol. Finally, I will report results on the viability of the proposed SDN -based approaches on currently available SDN -enabled hardware.
