        Deterministic Networking Application in Ring Topologies
                       draft-jiang-detnet-ring-04

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.
