Abstract

In this article, a mathematical model is developed to place controllers in multi-controller software-defined networking (SDN), while considering: resilience, scalability, and inter-plane latency. The model proved to be effective since it is able to provide resilient solutions under different fail-over scenarios, while at the same time avoid working close to the capacity limits of controllers, which offers a scalable model for multi-controller SDN.
