Remember a lot has changed between the book and now. 1) The initial window is now different 2) labc variable may influence how the cwnd responds are just 2 off the top of my head. You also may want to use a local trace buffer (as I mentioned earlier) since turning KTR on really really skew's

Hello, I need to get SCTP congestion window data for research purpose. I collected cwnd data from SCTP sender running on FreeBSD 7.0 machine by using KTR kernel log. After that, I tried to plot cwnd vs. time and generated graph. But I am unable to explain the graph and it is very different compared
