Does Ubiquiti manage the DPI signatures in-house? Is there any detail on how they work, or a process for suggesting things to include?
UniFi "traffic"
I have UniFi WAPs talking to an external hosted controller. If I look at the traffic generated by UniFi WAPs, I see "Web - Other" and "Other". It would be nice if this could be identified.
Apple iCloud Backups
Right now, this gets identified as "Amazon" (at least in my location). When an iOS device is connected to a known wifi network, plugged into power, and the screen locked, it will upload a backup file if it hasn't done so recently. This easily saturates upload links. Being able to identify this traffic through DPI would be fantastic.
