The Layer Two Tunneling Protocol (L2TP) defines the specification of congestion window sizes for data sessions. In addition, an LNS is given the capability to turn off sequence number processing for a data session, provided the LAC did not include the Sequencing Required AVP during session setup. This document specifies a mechanism whereby an L2TP peer can dynamically change the maximum window size values being used for a data session, in order to provide the flexibility to operate with smaller window sizes when history-bound protocols are operating over a session, and larger window sizes when no history-bound protocols are operating over a session.
