Hi,
Re-registered the route to REMAP on the publisher. (Yet another use case for "permanent" routes!) Looks good on the map. Thanks!

Subject: Re: [Operators] Spurious traffic to CSU/BYU hubs?
All:
I think this was due to a misconfiguration of nfd-autoreg.
When the BYU node was added it did not get added to the nfd-autoreg Blacklist for REMAP.
So, REMAP was sending ndnrtc Interests to BYU as if BYU was a local host.
I’ve corrected the config, restarted nfd and Jeff will retry his setup.

Jeff,
Can you give a little more information?
- name prefix used by the ndncon producer?
- strategy used by the name prefix?
- was the spurious traffic present before the test?

Hi,
On ndnmap I am consistently seeing spurious traffic to the CSU hub. Can
someone explain why?
Steps to reproduce:
- Start ndncon publisher with route via REMAP node (ndnradio example
emailed about earlier).
- Start ndncon consumer with route via CAIDA or UA (haven't tried others
though using CSU as the consumer hub works)
Results on ndnmap:
- See ~500-1000 kb/sec traffic bidirectional from consumer to publisher.
(e.g., CAIDA-UCLA-REMAP or REMAP-UA)
- But, also see 100-250 kb/sec traffic from REMAP-CSU, REMAP-BYU-CSU.
(note that traffic is asymmetric)
Screenshot attached for consumer via CAIDA hub case.
Thanks,
Jeff
