Mathematical model of a data flow management system in a cluster-based multicontroller SDN

Мигаль, С.В.

The problem of load balancing among controllers and ensuring network state consistency is one of the key challenges in multicontroller Software-Defined Networks (SDN). To address this issue, it is essential to develop adequate mathematical models that accurately describe the processes of data flow management. The subject of this study is the data flow control system within a clustered multicontroller SDN environment. The objective of the research is to develop a mathematical model that accounts for the dynamic clustering of SDN controllers when receiving data from network switches, enabling balanced load distribution across controllers and facilitating rapid reallocation of links between controllers and switches. The following results have been obtained. A three-tier hierarchical clustering approach for control and data transmission/reception devices within the system has been proposed. The relationships between controllers and OpenFlow switches within the developed clustered architecture have been formalized. Computational analysis of the control element loads has been performed. Conclusion. The proposed mathematical model enables efficient load balancing among controllers and ensures dynamic redistribution of workloads in the event of controller failure.
