                 DLEP Traffic Classification Data Item
            draft-ietf-manet-dlep-traffic-classification-02

Abstract

   This document defines a new Dynamic Link Exchange Protocol (DLEP)
   Data Item that is used to support traffic classification.  Traffic
   classification information is used to identify traffic flows based on
   frame/packet content such as destination address.  The Data Item is
   defined in an extensible and reusable fashion.  It's use will be
   mandated in other documents defining specific DLEP extensions.  This
   document aloas introduces DLEP sub data items, and sub data items are
   defined to support DiffServ and Ethernet traffic classification.

1.  Introduction

   The Dynamic Link Exchange Protocol (DLEP) is defined in [RFC8175].
   It provides the exchange of link related control information between
   DLEP peers.  DLEP peers are comprised of a modem and a router.  DLEP
   defines a base set of mechanisms as well as support for possible
   extensions.  DLEP defines Data Items which are sets of information
   that can be reused in DLEP messaging.  The base DLEP specification
   does not include any flow identification beyond DLEP endpoints.  This
   document defines DLEP Data Item formats which provide flow
   identification on a more granular basis.  Specifically it enables
   traffic sent by a router to use traffic flow classification
   information provided by the modem to identify which traffic flows.
   In this case, a flow is identified based on information found in a
   data plane header and one or more matches are associated with a
