                 DLEP Traffic Classification Data Item
            draft-ietf-manet-dlep-traffic-classification-00

Abstract

   This document defines a new DLEP protocol 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
