how to set data rate in case of tcp using ns2?
<p>I was trying to send ftp packets using tcp. which parameter in ns2 should i use to change the data rate of sender? i tried using the following to vary between 2 Mbps and 8 Mbps but seems like both are giving same results and does not vary the sender data rate.</p>

<pre><code>$ftp($i) set rate_ 2Mb
</code></pre>
