This document provides a mechanism to address issues that arise when
TCP is used for traffic that exhibits periods where the sending rate
is limited by the application rather than the congestion window.  It
provides an experimental update to TCP that allows a TCP sender to
restart quickly following a rate-limited interval.  This method is
expected to benefit applications that send rate-limited traffic using
TCP while also providing an appropriate response if congestion is
experienced.

This document also evaluates the Experimental specification of TCP
Congestion Window Validation (CWV) defined in RFC 2861 and concludes
that RFC 2861 sought to address important issues but failed to
deliver a widely used solution.  This document therefore reclassifies
the status of RFC 2861 from Experimental to Historic.  This document
obsoletes RFC 2861.

This document is a product of the TCP Maintenance and Minor Extensions Working Group of the IETF.
