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.
