Technical Summary

This document proposes a new mechanism for TCP and SCTP that can be
used to recover lost segments when a connection's congestion window
is small. This allows the transport to use fast retransmit to recover
segment
losses that would otherwise require a lengthy retransmission timeout.

Document Quality

There is limited implementation experience.  There are no MIBs or
other special items requiring expert review.
