Will FCC act? Observing traffic prioritization in Comcast’s network

berg'd: Bryan Berg's tumblr — Observing traffic prioritization in Comcast’s network: "What I’ve concluded is that Comcast is using separate DOCSIS service flows to prioritize the traffic to the Xfinity Xbox app (so that I’m using consistent terminology, I’m going to call this traffic “Xfinity traffic” in the rest of the post). This separation allows them to exempt that traffic from both bandwidth cap accounting and download speed limits. It’s still plain-old HTTP delivering MP4-encoded video files, just like the other streaming services use, but additional priority is granted to the Xfinity traffic at the DOCSIS level. I still believe that DSCP values I observed in the packet headers of Xfinity traffic is the method by which Comcast signals that traffic is to be prioritized, both in their backbone and regional networks and their DOCSIS network." An election year problem for the FCC and their 2 new commissioners? 'via Blog this'
