[Nfd-dev] 1-to-Many NDN-RTC test and hub strategy

Sorry, this was output from live test where I already changed strategy to multicast. Thus counters will make sense. I’d like to repeat - when multicast is active, everything works as expected.

I’ll send you output with default strategy soon.

Thanks,

Hi Peter

Face 264 appears to be the producer. 173764 Interests are forwarded to the producer, but only 118965 Data come back.
faceid=264 remote=udp4://10.10.12.3:6363 local=udp4://10.10.12.2:6363 counters={in={0i 118965d 150426049B} out={173764i 0d 19075583B}} non-local persistent point-to-point
Depending on application scenario, the difference between outgoing Interest counter and incoming Data counter may be normal, or it may indicate the producer application or forwarder is overloaded.

Outgoing Data counters toward consumers are: 118131, 118824, 118550, 117313, 118965, 116898, 118399, 117587, 118000, 117730. They are only slightly less than 118965 Data packets from the producer.
If “only one of the consumers received Data” as claimed, the sum of outgoing Data counters toward consumers should equal the incoming Data counter from producer.

To further diagnose this problem, have a look at outgoing Data counter on producer and incoming Data counter on consumers, and see whether they are different from the counters seen on the HUB.
Execute `nfd-status -f | grep udp4://10.10.12.2:6363` on producer and consumers to show the counters. It’s best to obtain counters from all nodes at the same time. Alternatively, stop all consumers and then obtain the counters.

Yours, Junxiao
