Red Hat Enterprise Linux delivers deterministic performance for time-sensitive networking

Red Hat Enterprise Linux delivers deterministic performance for time-sensitive networking Red Hat Enterprise Linux for real-time performance Our core approach to tackling this challenge is centered on two elements: The testing grounds: Test bed layout and setup Hardware and software The testing concept The data before and after TSN What the data really tells us Test 1B: No TSN Test 2B: With TSN The bottom line for IT and OT leaders Red Hat Enterprise Linux | Product trial About the author David Rapini More like this Enterprise-grade edge virtualization with Red Hat OpenShift and Arctera's InfoScale Create an efficient two-node edge infrastructure with Red Hat OpenShift and Portworx by Pure Storage Open Curiosity | Command Line Heroes What Can Video Games Teach Us About Edge Computing? | Compiler Keep exploring Browse by channel Automation Artificial intelligence Open hybrid cloud Security Edge computing Infrastructure Applications Virtualization Share The industrial world runs on timing and consistency. In manufacturing and operations, a predictable outcome isn't a nice-to-have; it's the core promise of the industrial system itself. Whether you're managing complex motion control or critical process loops, network communication must be reliable and predictable. Time-sensitive networking (TSN) is the essential evolution of Ethernet that brings determinism and a guaranteed delivery schedule to a standard open industrial network. But here's the reality check for information technology (IT) and operations technology (OT) leaders: TSN is great for the wire and hardware, but it's only as good as the software stack running on the devices at the edge. A jittery operating system can ruin a perfect TSN network before a packet ever leaves the device. Things like hardware interrupts, cache swapping, or even heavy application use (like AI or video management) can significantly impact the OS's ability to build and deliver packets in that crucial, repeatable fashion. At Red Hat, we understand the needs of Industrial and we know how important it is to be at peak performance. So we set up tests to prove it. We recently completed a hands-on technical validation, in collaboration with Intel, to demonstrate how Red Hat Enterprise Linux (RHEL) and Red Hat Device Edge deliver the precise, deterministic performance required for industrial TSN. A real-time kernel: A tuned operating system designed to use a deterministic scheduler to ensure critical tasks execute in fixed time bounds. Guaranteed predictable execution of high-priority workloads by controlling interrupt handling, resource locking, and context switching.
