the deployment of deterministic algorithms with stringent Quality
of Service (QoS) requirements that pave the way for commodity
Real-time (RT) networks. However, current QoS approaches are
conservative and under-provision the network, that becomes a
bottleneck when scaling or upgrading infrastructure. In this paper, we argue that the use of fixed priorities for flows – a common
practice in RT networks, is the root-cause of this issue. We
develop algorithms that use the global view provided by SDN to
develop on-demand, variable priority schemes. Evaluation shows
that this “correct by construction” approach increases network
utilization while still meeting the necessary QoS requirements,
thereby improving network robustness under high utilization.
