Abstract: Control planes of Software-defined Networks consist of multiple interconnected controllers to provide scalability and reliability. Existing approaches for distributed control planes add high complexity and neglect in-band connectivity issues. Subsequently, in this work, we propose a low-cost inter-controller communication service which (i) requires only few resources in terms of state, communication overhead, and computational com- plexity and (ii) provides isolation between control and production traffic using shared in-band channels.
