Abstract
This document specifies Deterministic Networking data plane
encapsulation solutions. The described data plane solutions can be
applied over either IP or MPLS Packet Switched Networks.
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-
