	Title		: Early Retransmit for TCP and SCTP

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.  The "Early Retransmit" mechanism allows the transport to
    reduce, in certain special circumstances, the number of duplicate
    acknowledgments required to trigger a fast retransmission.  This
    allows the transport to use fast retransmit to recover segment
    losses that would otherwise require a lengthy retransmission
    timeout.
