Abstract

   This document specifies the new label/header architecture for a new
   Multiprotocol Label Switching and proposes a new Label Standard.
   With this new architecture the aim is to provide more QoS options.

Internet-Draft        MPLS EXP/TC BIT EXPANSION         September 2016

1. Introduction

         This internet draft outlines a proposed change for the MPLS
         architecture as defined in RFC 3031 and the MPLS Label Stack
         Encoding RFC 3032 to suit the need of differentiated services
         and their requirements for more differentiated QoS.

         Current services require more specific QoS parameters then the
         8 possibilities provided by the 3 bit in the EXP/COS/TC field.

         3 bits is not enough to differentiate in our current service
         oriented environment.

         With this Proposed Standard a possibility of 32 QoS settings
         can be achieved.

2. Conventions used in this document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   In this document, these words will appear with that interpretation
   only when in ALL CAPS. Lower case uses of these words are not to be
   interpreted as carrying significance described in RFC 2119.

   In this document, the characters ">>" preceding an indented line(s)
   indicates a statement using the key words listed above. This
   convention aids reviewers in quickly identifying or finding the
   portions of this RFC covered by these keywords.
