Dear all,<br><br>I've correctly deployed my multi-hop wifi network, and I put OLSR into running. <br>I am evaluating TCP transmission flows by means of IRPEF+JPERF (such useful tool!).<br><br>My question is: have any of you ever experienced the following behaviour?<br>
The TCP throughput falls to zero because OLSR TC messages collide, thus provoking IP entries losses.<br>Hence, the path is corrupted, and the TCP transmission stops for few seconds, until new TC messages are correctly received by all the nodes..<br>
<br>Thank you all in advance!<br><br>BR,<br>Marco<br><br><div class="gmail_quote">On Sun, Jul 1, 2012 at 5:10 PM, Juliusz Chroboczek <span dir="ltr"><<a href="mailto:jch@pps.jussieu.fr" target="_blank">jch@pps.jussieu.fr</a>></span> wrote:<br>

</div>There's a lot of peer-reviewed papers that you should lookg at.<br>
<a href="http://Scholar.google.com" target="_blank">Scholar.google.com</a> is your friend.<br>

<br>
etc.<br>
<br>
You'll probably want to set up a non-trivial topology, and make three<br>
kinds of tests:<br>
<br>
- packet loss and latency (ping);<br>
- packet loss and latency for large packets (ping -s 1300);<br>
- TCP throughput (iperf);<br>
- TCP throughput with multiple flows (crossed iperfs);<br>
- packet loss and latency in presence of a flow (iperf crossed with ping).<br>
<br>
Please do tell us about your results.<br>
