<p>ps: tstat looks promising as well.<br><br><span class="gmail_quote">On 8/11/06, <b class="gmail_sendername">Mellia Marco</b> <<a href="mailto:mellia@tlc.polito.it">mellia@tlc.polito.it</a>> wrote:</span></p>

<br>> back to 1997 (the measurements are actually from 1994/1995) and the<br>> Internet has evolved since then. More recent work is kind of sparse...<br>><br>> If someone could provide a pointer, I'd really appreciate that.
