Automated Bootstrapping of A Fault-Resilient In-Band Control Plane

Adoption of Software-defined Networking (SDN) in critical environments, such as factory automation, avionics and smart-grid networks, will require in-band control. In such networks, the out-of-band control model, prevalent in data center deployments, is inapplicable due to high wiring costs and installation efforts. Existing designs for seamlessly enabling in-band control plane cater only for single-controller operation, assume proprietary switch modifications, and/or require a high number of manual configuration steps, making them non-resilient to failures and hard to deploy.
