Communication Networks with Multiple SDN Controllers
Peter Trúchly, Jakub Kubica · 2023
Software-defined networks are slowly but surely coming into production. Currently, there are several different SDN architectures. As SDN solutions continue to evolve, there is room to improve current solutions in networks with multiple SDN controllers. One of the researched aspects of the SDN network is the deployment of multiple controllers to improve reliability, load balancing, and efficiency. Each controller will manage its SDN domain. In this paper, we proposed an efficient SDN architecture based on a flat multicontroller multidomain network that provides efficient load balancing in the network. We demonstrated and verified its performance via simulations in Mininet environment with Ryu controllers.
