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.
