An adaptive resource provisioning scheme for industrial SDN networks

• Many industrial domains face the challenge of ever growing networks, driven for example by Internet-of-Things and Industry 4.0. This typically comes together with increased network configuration and management efforts. In addition to the increasing network size, these domains typically are subject to adaptive load situations that pose an additional challenge on the network infrastructure.Software defined networking (SDN) is a promising networking paradigm that reduces configuration complexity and management effort in Ethernet networks. In this work, we investigate SDN in context of adaptive scenarios with QoS constraints. Our approach applies monitoring of several thresholds which automatically trigger redistribution of resources via the central SDN controller. This setup leads to an agile system that can dynamically react to load changes while the infrastructure is not overprovisioned. The approach is implemented in a low-level simulation environment where we demonstrate the benefits of the approach using a case study.
