<p class="MsoNormal">I checked the web page: <a href="https://ndndemo.arl.wustl.edu/">
https://ndndemo.arl.wustl.edu/</a>. It seems like the latest NDN testbed contains 37 NDN nodes. However, the visual view (at the bottom of the page) of the testbed topology only contains 35 NDN nodes. I am having trouble drawing a visual of NDN topology. I
am wondering if a visual view of the latest NDN testbed is available? <o:p></o:p></p>

<p class="MsoNormal">The mathematics model is at <a href="https://www.caida.org/publications/papers/2010/hyperbolic_geometry_complex/">https://www.caida.org/publications/papers/2010/hyperbolic_geometry_complex/</a> and <a href="https://www.caida.org/tools/utilities/hyperbolic-graph-generator/">https://www.caida.org/tools/utilities/hyperbolic-graph-generator/</a>
, but I cannot understand them.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The actual coordinates used on the testbed is determined by querying the BGP AS number of each node in this dataset:

<p class="MsoNormal">However, this dataset was generated in 2013, and many AS numbers active today after missing. I personally have at least 3 servers having AS numbers not in this dataset.<o:p></o:p></p>

the same as topologies in the newest mini-ndn git version. The topology "<a href="https://github.com/named-data/mini-ndn/blob/76dbe6633c10f4e833c9329482b10b8b44a0417d/topologies/current-testbed.conf" target="_blank"><span style="color:#4A6EE0">current-testbed.conf</span></a>"
