我已经删除了这些代码（从“流量”部分中删除），并且可以正常运行，但无法正常运行：
for {set k 20} {$k < $val(nn) } {incr k} {
set tcp($k) [new Agent/TCP]
set sink($k) [new Agent/TCPSink]
$ns_ attach-agent $node_($k) $tcp($k)
$ns_ attach-agent $node_([expr $val(nn)-$k-1 ]) $sink($k)
#$ns_ connect $tcp($k) $sink($k)
set ftp_($k) [new Application/FTP]
$ftp_($k) attach-agent $tcp($k)
$ftp_($k) set packetSize_ 1024
#$ns_ at [expr rand()] "$ftp_($k) start"
$ns_ at 1.0 "$ftp_($k) start"
$ns_ at $val(stop) "$ftp_($k) stop"
}
