vpn increases video latency

asked 2018-06-06 13:56:59 -0500


I'm using tinc VPN to access robots in the field over a cellular network. I have been struggling to get video latency below 2 seconds. I just discovered that tinc VPN is adding most of that latency to the video stream.

Has anyone used OpenVPN or IPsec who can speak to how well those work with regards to video latency. Or I'd take suggestions on other technologies to use.

You'll probably want to ask this on https://robotics.stackexchange.com as this is a more general question rather than a ROS-related one. You'll probably get an answer faster (and maybe a better one too) there.
