          DetNet Data Plane Protocol and Solution Alternatives
                      draft-ietf-detnet-dp-alt-00

Abstract

   This document identifies existing IP and MPLS, and other
   encapsulations that run over IP and/or MPLS data plane technologies
   that can be considered as the base line solution for deterministic
   networking data plane definition.
