Hi Chris,
	I am using tcl script... What I have done is using this command:

***************************************************************************
	proc tcpDump { tcpSrc interval } {
	global ns
	proc dump { src interval } {
		global ns
		$ns at [expr [$ns now] + $interval] "dump $src $interval"
		puts [$ns now]/cwnd=[format "%.4f" [$src set cwnd_]]/ssthresh=[$src set ssthresh_]/ack=[$src set ack_]
		}
	$ns at 0.0 "dump $tcpSrc $interval"
}
                                    
tcpDump $connection 1.0

****************************************************************************

The $connection is from the previous command "set connection [$ns connect $tcp $sink]".

Hope, it answers your question.
