Based on an appropriate detection algorithm, the Eifel response
algorithm provides a way for a TCP sender to respond to a detected
spurious timeout.  It adapts the retransmission timer to avoid
further spurious timeouts and (depending on the detection algorithm)
can avoid the often unnecessary go-back-N retransmits that would
otherwise be sent.  In addition, the Eifel response algorithm restores
the congestion control state in such a way that packet bursts are
avoided.
