Port 80 can be deep-packet-inspected to confirm it's HTTP, and 443 can be confirmed to be SSL, and so everything else was shut down. So everything had to be delivered over those, or it failed. In my world, that means that IoT devices talking custom protocols over SSL have to use 443 to the datacenters because the corporate firewall people won't allow anything else out. And if you can't demo it from the "guest" network at a company, you won't make any sales there. OTOH, fq_codel should hash them out separately based on the destination IP and source ports as separate connections. Not separable into a QoS bucket, but at least able to pry apart the streams for fairness... -Aaron ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel

One note: on my flight to Hawaii for the IETF, I tried running netperf-wrapper to see just how bloated the airplane system was (I presume it was GoGo, but don't know for sure: I was on United). On my second attempt to run the test, the on board system crashed entirely. I did not try again. - Jim On Tue, Jan 6, 2015 at 2:37 PM, Dave Taht wrote: > On Tue, Jan 6, 2015 at 9:26 AM, wrote: > > GoGo does not need to run “Man in the Middle Attacks” on YouTube > > re: http://www.reed.com/blog-dpr/?p=174 > > I amplified via g+ and mentioned to slashdot. > ( > http://slashdot.org/submission/4107907/gogo-airline-network-blocks-youtube-when-they-could-just-fix-their-bufferbloat > ) I don't use reddit, but if someone here wants to hit this topic > there, perhaps it will help. > > I am very perturbed by the https interception stuff and agree that > they should fix their bufferbloat instead!
