Cable industry gets it right with DOCSIS 3.1
Looks like the light bulb came on with the goal of 0% of retransmitted packets across their cable networks. Wish all other types or Internet connections would require some type of TCP/IP RFC standard that would resolve the bufferbloat issue. Know that OpenWrt 18.06.2 r7676-cddd7b4c77 / LuCI openwrt-18.06 branch (git-19.020.41695-6f6641d) / SQM - cake - piece_of_cake.qos has done the job of resolving my bufferbloat issue on my Frontier 150/150 FIOS connection.

Solve Bufferbloat Problems with a DOCSIS 3.1 Modem

Phil asks, “Comcast/XFINITY has raised their rental fee to $11/month and I’m going to buy a new modem. Should I buy DOCSIS 3.0 or is there a good reason to buy DOCSIS 3.1 today?”
At this point, if you’re buying a modem for Xfinity I would go with a DOCSIS 3.1 modem, for sure. Not only does it future-proof you for if/when you want to get Gigabit service, it also gives you the new DOCSIS-PIE queue management that’s mandated to be in all DOCSIS 3.1 modems, even when they’re running DOCSIS 3.0 connections. DOCSIS-PIE is mandated by Cable Labs for DOCSIS 3.1 modems (and later) because it effectively solves that upstream bufferbloat problem which plagues all pre-DOCSIS 3.1 modems.
This makes a HUGE difference, and means you no longer have to think about solving Bufferbloat with WAN QoS management in your router.
