Deterministic Networking Use Cases
Abstract
This document presents use cases for diverse industries that have in
common a need for "deterministic flows". "Deterministic" in this
context means that such flows provide guaranteed bandwidth, bounded
latency, and other properties germane to the transport of time-
sensitive data. These use cases differ notably in their network
topologies and specific desired behavior, providing as a group broad
industry context for Deterministic Networking (DetNet). For each use
case, this document will identify the use case, identify
representative solutions used today, and describe potential
improvements that DetNet can enable.
