DLEP Traffic Classification Data Item
draft-ietf-manet-dlep-traffic-classification-04
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 also 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
