Ethernet’s Role in the Operational Technology (OT) Evolution

OT networks are purpose-built networks that are found in Industrial and Building Automation applications. They control profit-making processes and ensure the comfort and safety of building occupants. In the past, these networks have been completely separate from the IT network, utilizing a number of legacy communications protocols.

Today, Ethernet enjoys a pervasive presence in the upper layers of OT networks. The Ethernet ecosystem begins to focus more intently on OT networks with the advent of Single Pair Ethernet (SPE) and its certain impact on the edge of OT networks. Thus, OT networks are beginning a rapid evolution to a resilient, single protocol network that can easily converge with the IT network, creating conspicuous business value.
