Abstract: Distributed controllers have been proposed for solving the scalability and reliability of the centralized controllers problems in software‐defined networking. This paper has presented a new two‐layer distributed controller structure Cacc with the features of overlap management and dynamic management. Cacc has advantages of load balancing and manageability. Furthermore, this paper has conducted the performance modeling of controller topologies and has proposed a new placement problem for Cacc: capacitated multi‐controller placement problem, in which one local controller is assigned to 2 or more root controllers with capacity limitation to achieve a high reliability. Both of the analysis and experiment results have verified the reliability advantages of capacitated multi‐controller placement problem.
