"Systematic Approach to Managing Software Defined Networks"
Software-defined Networks and programmable data-planes represent a shift in networking paradigm, which enables novel applications. Despite the growing interest and adoption of SDNs, SDNs remain plagued with availability and performance problems.In this talk, I discuss recent and ongoing work by my group to analyze these paradigms and create systematic abstractions that provide control over performance and availability. First, I will discuss Tardis a system that improves fault tolerance by leveraging the novel programmability provided by SDNs to identify and transform the failure-inducing event(s). Second, I will discuss a pair of projects, Hermes and SCC, that revisits traditional storage principles and applies them to network updates. Through this work, I will demonstrate how the centralization and programmability offered by SDNs enables us to more systematically reason about traditional networking issues such as availability and performance.
