                        draft-ietf-detnet-ip-07

Abstract

   This document specifies the DetNet data plane operation for IP hosts
   and routers that provide DetNet service to IP encapsulated data.  No
   DetNet-specific encapsulation is defined to support IP flows; instead
   the existing IP and higher layer protocol header information is used
   to support flow identification and DetNet service delivery.  This
   document builds on the DetNet Architecture and Data Plane Framework.
