Design of Highly Available Distributed Control Plane for Software-Defined Networks
Vasily Pashkov · 2022
In the software-defined networks the distributed control plane can consist of one or more software controllers, running at different points in the network. The paper presents the actual problem of high available distributed control plane design for real large-scale software defined networks. To achieve this goal, we propose the method for choosing distributed control plane design and its controller placement taking into account the worst delay between the switches and its controller, availability factor and minimum total numbers of controllers.
