Hi, Here is the code for recursively showing the value of the instvar cwnd_ of TCP for every 0.5s. $ns at 1.5 "show_tcp_seqno" proc show_tcp_seqno {} { global tcp ns puts "TCP CWND is [$tcp set cwnd_]" $ns at [expr [ $ns now ] + 0.5] "show_tcp_seqno" } Feel free to adjust it your

[ns] Test cwnd size for TCP variants

2010-08-15 Thread Ghassan Akrem
Hi all,   I try to test cwnd size for variant TCP,by using ns-2 simulation, in fact I want to test the performance of TCP throughputs of ordinary  TCP and some other TCP's by monitoring cwnd size for each variant.   I hope to get some script, TCL source code perform this test.   Regards
