<abstract>
<t>This document defines TCP's four intertwined congestion
control algorithms: slow start, congestion avoidance, fast retransmit,
and fast recovery.
In addition, the document specifies how TCP should begin transmission
after a relatively long idle period, as well as discussing various
acknowledgment generation methods.</t></abstract></front>
