Abstract

   This document describes mechanisms which enable the Layer Two

   Tunneling Protocol (L2TP) to negotiate desired Per Hop Behavior (PHB)

   code for the L2TP control connection, as well as individual sessions

   within an L2TP tunnel.

   L2TP provides a standard method for tunneling PPP packets.  The

   current specification provides no provisions for supporting

   Differentiated Services (diffserv) over the L2TP control connection

   or subsequent data sessions.  As a result, no standard mechanism

   currently exists within L2TP to provide L2TP protocol negotiations

   for service discrimination.
