[Mini-NDN] Interfaces went down in minindn

Wed Apr 6 07:40:15 PDT 2016

What is the rate of sending interests?

Can you try lowering it and see if interest drops are decreased?

Hi everyone,

I have been running some experiments using minindn using NDN traffic generator for interest and data generation. I am facing a few issues as I am unable to get the data packets in response after a certain period of time. In my configuration I am making cs store size to be zero so that all interests can reach the producer. While investigating the issue of interest drops I found few errors in the nfd logs. Below are the few errors which I am getting in the log file:

1459932297.745268 ERROR: [EthernetTransport] [id=264,local=dev://sa-eth0,remote=ether://[01:00:5e:00:17:aa]] pcap_next_ex failed: The interface went down

1459932297.761311 ERROR: [EthernetTransport] [id=263,local=dev://sa-eth1,remote=ether://[01:00:5e:00:17:aa]] pcap_next_ex failed: The interface went down

1459932297.777269 ERROR: [EthernetTransport] [id=262,local=dev://sa-eth2,remote=ether://[01:00:5e:00:17:aa]] pcap_next_ex failed: The interface went down

Due to this, the interests are not getting satisfied. Attached are the nfd logs of the producer(similar errors are being observed on the other nodes as well). Please if someone can help me resolving the issue.

Best Regards,
