Hi Spridon,
<div class=""><br class="">
</div>
<div class="">The problem is printing the topology with real locations. For example, one node located at USA and the OTHER one located in EU, when I tried to print the topology these nodes ends next to each other, I think, they based on link delays not real
distances.</div>
<div class=""><br class="">
</div>
<div class="">So the questions are: Are X amd Y coordinates effects the results or not? How can I get real coordinates from this file (<a href="https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf" class="">https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf</a> ).—The
created for angle and radius also does not any make sense because node coordinates are not ok, for example UCLA and MINHO angle and radius. </div>

Hi,
<div class=""><br class="">
</div>
<div class="">if you can figure out the average delays of the testbed links, you can create a text file that reproduces the topology based on the link delays.</div>
<div class=""><br class="">
</div>
<div class="">I do not understand if your problem has to do with how things look or it is a concern that can impact the simulation results.</div>
<div class=""><br class="">
</div>
<div class="">Thanks,</div>

Dear ndnSIM developers,
<div class=""><a href="https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf" class="">https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf</a> </div>
<div class=""><br class="">
</div>
<div class="">The locations of nodes are not correct when I do —vis. For example, “minho” node is locates next to the “ucla”. I do guess they are based by link delays by radius and angles (even I converted them for x and y, they are almost the same). Is there
any way to get real geographical ndn-testbed locations by ndnSIM. </div>
