Hi Junxiao,
<div class=""><br class="">
</div>
<div class="">I’m sorry for not being clear. </div>
<div class=""><br class="">
</div>
<div class="">What I meant is that all consumers start simultaneously and what I repeatedly observe, is that they are unable to catch up with the latest produced data in a synchronous manner, what is expected. Instead, chasing phase resolution happens one (or
few) consumer(s) at a time. Consumers are identical and in the beginning express same interest - with rightmost child selector enabled. </div>
<div class=""><a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-test-real-time-metrics?panelId=4&fullscreen&from=1466801762500&to=1466801788564" class="">Here </a> (login/pw: guest/ndnguest) you can see “rebufferings stairs”
- which indicate that consumer was not able to get any data, so it started over. It feels like NFD was answering one consumer (rightmost interest) at a time.</div>
<div class=""><br class="">

<div class="">I attached pcap file for the first 1-1.5 minute of test.</div>

</div>
<div class="">I ran more 1-to-10 tests recently (here are <a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-tests-test-run-overview?from=1466566688346&to=1466567022507&var-runtime=15m" target="_blank" class="">the results</a> of
one out five tests) and observe an unusual behavior: consumers are not able to get data all simultaneously, instead - they join one-by-one. This can be seen from <a href="http://ec2-52-90-158-238.compute-1.amazonaws.com:3000/dashboard/db/ndn-rtc-tests-test-run-overview?from=1466566688346&to=1466567022507&var-runtime=15m&panelId=15&fullscreen" target="_blank" class="">rebufferings

that, consumers get timeouts for the initial interests.</div>
