This is a very good question, I will stare at "iftop" (and check the xbox's network settings, if I can), the next time I notice it's updating.
The report from my "users" :) was that pausing xbox updates solved their video streaming issues -- but, it may be that there was other network traffic or that multiple systems were doing updates, and the update they paused gave back enough bandwidth for their streams. I will look at traffic summore and let you know if I was mistaken about the xbox. It is now using ipv6 for at least some updates, I do know that much for certain, but hopefully I'm wrong about it using too many v6 addresses. Jonathan, thanks for the tips re: using ports or remote addresses -- Hmm, I don't know -- is it possible to identify (and thus classify) plain old bulk downloads, as separate from video streams? They're both going to use http / https (or possibly QUIC) -- and they're both likely to come from CDN networks... I can't think of a simple way to tell them apart. Is this enough of a problem that people would try to make a list of netblocks / prefixes that belong to video vs other CDN content? I do notice video streams are much more bursty than plain downloads for me, but that may not hold for all users. That is, for me at least, a video stream may average 5mbps over, say, 1 minute, but it will sit at 0mbps for a while and then burst at 20mbps for a bit. I can't think of a way to mark such traffic though. Is there a place where such complex, custom rules for marking packets would sit? Perhaps a userspace daemon that looks at traffic with pcap?
