Technical Summary
 
This document recommends a way for a sender to respond to a spurious TCP 
timeout, provided that one has been detected (such detection mechanisms are ou
of scope of this document). Furthermore, it adapts the retransmission timer to 
avoid additional spurious timeouts, and restores congestion state in such a wa
that packet bursts are avoided.
 
Working Group Summary
 
The TSVWG working group supports the advancement of this document. It describe
a building block for a complete system that avoids spurious TCP 
retransmissions. Although there are a number of different philosophies for 
overall approaches to this problem, this document provides a modular component 
that could be integrated into several such approaches.
