This presentation is based on my PhD thesis topic - ‘sBGP: A hybrid SDN approach to interdomain routing’. It places current SDN research work in the context of today’s challenges in core internet routing, starting with a _very_ quick introduction to the principles of SDN, then briefly introducing some current projects (ONF/Atrium, OpenDaylight) which are aimed at applying SDN principles to BGP/core routing, before moving onto discuss the practical limitations as well as limited ambition of these projects. I then move onto an outline of my proposal, including a discussion of previous work in the field, and an explanation of what I think are the novel aspects of my proposal. Finally, I outline some of the possible benefits of my approach and discuss the crucial practical question of how my work could be applied in large scale production networks.
I hope to generate sufficient interest that I may be able to persuade one or more transit network operators to collaborate in my work.
About me: My name is Nicholas Hart, and I am a researcher and PhD student at Lancaster University. I am a mathematician and software engineer with a background in networks, having previously worked for equipment vendors such as Cascade/Ascend/Lucent and Redback Networks, and subsequently consulted for service providers such as BT and Vodafone.
