Cyber-Physical Production Systems (CPPS) and Industrial Internet of Things (IIoT) will improve the flexibility of the future production systems in the newest smart factories. In advanced manufacturing industries, a large number of machines, goods, control systems, and information systems will be interconnected. For this reason, it is necessary to implement load balancing technologies that improve responsiveness and increase the availability of applications, particularly when low-cost devices are used. This paper presents a novel architecture approach for load balancing using Software-Defined Networking (SDN). The proposal is based on IEC-61499 standard over OPC UA in industrial communications, and it is aimed at optimizing resources, maximizing throughput, minimizing response time, and avoiding overload in low-cost devices.
