A scalable factory backbone for multiple independent time-sensitive networks

Convergence of time-sensitive machine control networks as part the operational technology (OT) with ubiquitous information (IT) is an essential requirement for ongoing digitalization production. In this paper, we review fundamental differences between both technologies, challenges to be solved, existing and upcoming solutions like TSN their limitations. Furthermore, introduce Ethernet extension a backbone network at factory scale line rates 10 - 100Gbit/s. The intended carry massive amounts IT traffic together multiple independent OT precision leading-edge field bus technologies in sub-microsecond range. remains transparent does not require changes attached sub-networks. We prove our claims by prototype measurements, interoperability tests trials.
