Adopting distributed control planes is critical towards ensuring high availability and fault-tolerance of dependable Software-Defined Networks (SDNs). However, designing and bootstrapping a distributed SDN control plane is a challenging task, especially if to be done in-band, without a dedicated control network, and without relying on legacy networking protocols. One of the most appealing and powerful notions of fault-tolerance is self-organization and this paper discusses the possibility of selforganizing algorithms for in-band control planes.
