Deterministic Networking Application in Ring Topologies
draft-jiang-detnet-ring-00
Abstract
Deterministic Networking (DetNet) provides a capability to carry
data flows for real-time applications with extremely low data loss
rates and bounded latency. This document describes how DetNet can
be used in ring topologies to support Point-to-Point (P2P) and
Point-to-Multipoint (P2MP) real-time services.
