RFC 3742, Limited Slow-Start for TCP with Large Congestion Windows,
March 2004.

The discussion of the number of round-trip times needed to achieve
a particular congestion window was not correct.

In Section 2:

   the invariant is maintained so that the congestion window is
   increased during slow-start by at most max_ssthresh/2 MSS per round-
   trip time. 

Should be:

   the invariant is maintained that the congestion window is
   increased during slow-start by at most max_ssthresh MSS per
   round-trip time (and at least max_ssthresh/2 MSS per round-trip
   time).



Later in Section 2:

   it
   takes:

      log(max_ssthresh) + (cwnd - max_ssthresh)/(max_ssthresh/2)

   round-trip times to reach a congestion window of cwnd, for a
   congestion window greater than max_ssthresh.

Should be:

   it
   takes at least:

      log(max_ssthresh) + (cwnd - max_ssthresh)/(max_ssthresh)

   and at most:

      log(max_ssthresh) + (cwnd - max_ssthresh)/(max_ssthresh/2)

   round-trip times to reach a congestion window of cwnd, for a
   congestion window greater than max_ssthresh.


Later in Section 2:

   Thus, with Limited Slow-Start with max_ssthresh set to 100 MSS, it
   would take 836 round-trip times to reach a congestion window of
   83,000 packets,

Should be:

   Thus, with Limited Slow-Start with max_ssthresh set to 100 MSS, it
   would take at least 836 round-trip times to reach a congestion window of
   83,000 packets,
