[Nfd-dev] NFD dropping packets

[Gusev, Peter]

Hi devs,


I recently noticed that I can’t fetch ndnrtc video stream with somewhat old (~2months) code. In the app I’m getting timeouts:

	1543953646377	[WARN ][       remote-stream]-          operator(): error fetching stream meta: Time out for interest /touchdesigner/ndnrtcOut/ndnrtc/%FD%03/video/s/_meta

while in NFD log I observer these messages:

	1543953961.057775 WARNING: [GenericLinkService] [id=287,local=unix:///private/var/run/nfd.sock,remote=fd://73] packet parse error (unrecognized element of critical type 9): DROP

Face 287 is an application face:

	faceid=287 remote=fd://73 local=unix:///private/var/run/nfd.sock congestion={base-marking-interval=100ms default-threshold=65536B} counters={in={0i 0d 0n 1120B} out={0i 0d 0n 0B}} flags={local on-demand point-to-point congestion-marking}

I was wondering whether these DROP messages relate to my code or not. I still can fetch video with my latest code though.

I’m using NFD 0.6.4 (macOS).

Thanks,
