Summary from nexthop conference page [0]: In this talk, we will discuss Facebook’s backbone, its evolution, and the motivation behind it. We’ll see what our current SDN backbone architecture is and how it addresses traffic engineering and failure protection. That context will also be useful for looking at the engineering framework that allows us to scale and innovate at speed while maintaining a reliable foundation.
