Deterministic Networking Use Cases
draft-ietf-detnet-use-cases-20
Abstract
This draft presents use cases from diverse industries which 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 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. The Use
Case Common Themes section then extracts and enumerates the set of
common properties implied by these use cases.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
