Beschreibung:
Publish/subscribe communication offers outstanding flexibility, but lacks the predictability required for guaranteeing (hard) realtime constraints in industrial environments such as future smart factories. In this paper, we review existing publish/ subscribe systems, identify their shortcomings, and derive research objectives for a converged realtime network infrastructure for the Industrial Internet of Things (IIoT) that is based on publish/subscribe and Software-Defined Networking (SDN).
