Hi,

I was digging around in my /dev/ folder today and noticed a file called network_latency and network_throughput. This peaked my interested as I am making a robot that communicates over cell modem. After researching a little bit I found that these files are used for pm-qos (power-management - quality of service). A program can write to this files to set QOS settings for that program. I was wondering if anyone out there has used these for a robot? They seem like they could be helpful but I don't see any mention of anyone using them with ROS.

I'm not aware of any ROS packages directly interacting with these. They are potentially useful for robots communicating over those network links. I suspect that if people are using that functionality they are likely doing it outside of their ROS context, as it's more of a system configuration than a data processing node.
