hi ns-users,
i am checking  out the test-suite in ns .
can anyone tell me the  what happens in tcp-tahoe ...after congestion is
detected...
as far as i know ..the cwnd_=1;ssthresh=wnd/2;timer back off;
now my problem is...when a lost packet is detected ..is  Go-Back-n
implemented ..or selective repeat ..
my graph shows (packet vs time) that it is Go Back n for some packets
...and then the usual retransmission ..in otherwords...only some of the
packets are unecessarily retransmitted..
can someone help me ?
thanx
..vijay
