[ns] Bug in tcp-full (timestamp option

[Morten Schlaeger <morten@ee.tu-berlin.de>]

hi,

in case the timestamp option is used with the TcpFull agent the
t_backoff_ counter is not
set back to 1, when a new ack is received.

I changed our local code to:

diff -u ns-2.1b7/tcp-full.cc local
--- org/tcp-full.cc     Fri Sep  1 05:04:07 2000+++ local/tcp-full.cc

t_backoff_ = 1;
                        recent_age_ = now();
                        recent_ = tcph->ts();
                         rtt_update(now() - tcph->ts_echo()); 

Best regards,
