<p>No, the figure of the paper should be possible to achieve. The CPU is the bottleneck because one has to run 6 NFD, 6 NLSR instances on a single machine. I have run a 10 node pingall experiment on a VBox VM with 2.5GB RAM and 2 CPUs without so much variation.</p>
<p><br>
</p>
<p>To turn off the logs:</p>
<p>Change DEBUG to NONE here:</p>
<p><a href="https://github.com/named-data/mini-ndn/blob/master/ndn/nlsr.py#L123" class="m_1849810668381939519m_6671776342309163625OWAAutoLink" id="m_1849810668381939519m_6671776342309163625LPlnk703886" target="_blank">https://github.com/named-data/<wbr>mini-ndn/blob/master/ndn/nlsr.<wbr>py#L123</a><br>
</p>
<p><br>
</p>
<p>and make sure that this also set to NONE:</p>
<p><a href="https://github.com/named-data/mini-ndn/blob/master/ndn/nfd.py#L34" class="m_1849810668381939519m_6671776342309163625OWAAutoLink" id="m_1849810668381939519m_6671776342309163625LPlnk80158" target="_blank">https://github.com/named-data/<wbr>mini-ndn/blob/master/ndn/nfd.p<wbr>y#L34</a><br>
</p>
<p><br>
</p>
<p>Then reinstall Mini-NDN, sudo ./install.sh -i</p>
<p><br>
</p>
<p>Also make sure that in your topology file all the log levels are set to NONE if there is such an option after the nodes.</p>
<p><br>
</p>
<p>Then try to run the experiment again (If possible turn off the GUI in VM, i.e. login in to command line and run the experiment from there - just to free up some more CPU).</p>
<p><br>
</p>
<p><span style="font-size:12pt">In your graph the y-axis is the RTT in ms? What are the delays you have set on the links of the topology?</span><br>
</p>
<p><span style="font-size:12pt">(If possible, can you share the topology file?)</span></p>

<div>Hello,<br>
</div>
no there aren't any timeouts and what you see there is not a zero it is 10^0 which is equal to 1.<br>
</div>
I'm running my linux on a vmware virtual machine with the configurations bellow:<br>
<img alt="Inline image 1" src="cid:ii_1587b57a26b4856e" width="471" height="265"><br>
so you're saying that this results which I've got in my figure is reasonable for the topology and it shouldn't exactly be like the figure in the paper?<br>
Thank you<br>

<p>Have you verified that the ping data is correctly depicted on your figure?</p>
<p>Are there any timeouts in there? Because I see some zeros.</p>
<p><br>
</p>
<p>RTT can be have variation in Mini-NDN because of multiple NFDs are running on the same machine.</p>

Usually for such a small topology it should not be a problem.</p>
<p></p>
<p><br>
</p>
<p>One thing you can try is that if you are collecting NFD, NLSR, or any other logs, turn them off.</p>
<p>That is turn off all the logs except the ping data.</p>
<p><br>
</p>
<p>Other thing to try is to use a machine with more CPU power. </p>

<div>Hello all, <br>
</div>
<div>I'm new to mini-ndn and I'm trying to implement the following topology:<br>
<img alt="Inline image 1" src="cid:ii_15876715860b1e3d" width="395" height="140"><br>
</div>
<div>so I use minindnedit to implement it with the following information:<br>
<img alt="Inline image 2" src="cid:ii_15876728fa4e0582" width="395" height="262"><br>
</div>
<div>and based on the paper which represents this topology it is expected to get this figure from it's information:<br>
<img alt="Inline image 3" src="cid:ii_158767407cf733b8" width="395" height="252"><br>
</div>
<div>which the blue "+" represents the ping-data in the case that no node fails, but when I try to implement it using pingall experiment my figure will come out like this:<br>
<img alt="Inline image 4" src="cid:ii_158767b561fe7208" width="471" height="265"><br>
</div>
<div>as you can see there is more swing in the blue '+'s than it is expected, any idea why it is happening?<br>
</div>
thank you<br clear="all">
