Hi Junxiao,
<div class=""><br class="">
</div>
<div class="">I started to run tests with NDN-RTC docker image and first, tried simple topologies - 1-to-many. </div>
<div class="">The topology is the following:</div>
<div class=""><br class="">
</div>
<div class="">P — H — C1</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>|——C2</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>|——C3</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>|——…</div>
<div class=""><span class="Apple-tab-span" style="white-space: pre;"></span>|——CN</div>
<div class=""><br class="">
</div>
<div class="">where P - producer, H - hub and Ci - i-th consumer.</div>
<div class=""><br class="">
</div>
<div class="">I.e. all consumers are connected to the same hub.</div>
<div class="">Hub registers prefixes like <b class="">/ndn/edu/ucla/remap/ndnrtc/user/clientX
</b>where <b class="">clientX </b>- is an NDN-RTC user name for one of the [P, C1, C2, … CN] (for example, publisher publishes under
<i class="">client1</i> username). I don’t alter any strategies, so by default, Hub uses best-route.</div>
<div class=""><br class="">
</div>
<div class="">I tried 1-to-2 topology but noticed that only one of the consumers received data (see results <a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-test-metrics?from=1464329468261&to=1464329772934" class="">here</a> login/pw:
guest/ndnguest) - around 23:14:47 I changed strategy to multicast on the router and all clients were able to receive the data.</div>
<div class="">I run same experiment for 1-to-4 topology and got same <a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-test-metrics?from=1464330005051&to=1464330909765" class="">results</a> (changed strategy at around 23:21:30). </div>
<div class="">…<a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-test-metrics?from=1464335773279&to=1464336374031" class="">same</a> with 1-to-10 (changed strategy at 00:56:40).</div>
<div class=""><br class="">
</div>
<div class="">Can you please advise on how hub should be configured for this test-scenario? Is it the known issue with best-route when interests from other clients are suppressed as being treated as retransmissions? Shouldn’t each consumer have it’s own face
on the hub?</div>
<div class=""><br class="">
</div>
<div class="">I looked into log files - some data arrives - segments of key frames that were requested by rightmost interest.</div>
