Abstract

We highlight a problem that the networking community has largely overlooked: ensuring that the inputs to network controllers in Software-Defined Network (SDN) WANs correctly reflect the state of the network. We show that “incorrect” inputs are a common cause of major outages in production and propose new directions to address these.
