Tired of slow internet connections? CableLabs announces a new version of DOCSIS 3.1 (Data Over Cable Service Interface Specification) with Full Duplex 10Gbps connectivity. From an article at The Register:
Which is why an announcement by the cable industry's research and development arm, CableLabs, this week is such good news. The organization has completed work on an upgrade to the next-generation DOCSIS 3.1 spec that in the next few years will replace the "M" in Mbps with a "G" for gigabit.
DOCSIS 3.1 is the cutting edge of home cable technology, and big players such as Comcast in the US are testing it in specific markets with a new generation of modems. That testing and rollout of near-gigabit broadband in the US, UK, Canada and beyond has been somewhat marred, though, by the fact that high-speed DOCSIS 3.1 home gateways powered by Intel Puma chips suffer from annoying latency jittering under certain conditions, and can be trivially knocked offline by attackers. No fixes are available.
Those hardware problems aside, the DOCSIS 3.1 spec has another issue: it sticks to the age-old sucky 10-to-1 downlink-uplink ratio.
No longer with the Full Duplex Data Over Cable Service Interface Specification. Full Duplex DOCSIS 3.1 will allow broadband subscribers – in the next two years – to benefit from up to 10Gbps both up and down. And it will be possible on existing household connections rather than requiring the installation of new fiber.
[...] You can find out more about Full Duplex DOCSIS 3.1 on the CableLabs website.
So, you could reach your monthly 1 TB data cap allowance in just under 3 hours, assuming, of course that the upstream link is not so oversubscribed that you only actually get a fraction of that.
All kidding aside, that is a huge speed improvement. A quick back-of-the-envelope calculation suggests that a 100GB BDXL Blu-ray disk could be downloaded in about 2 minutes. As the connection is full-duplex, it could be uploaded in about 2 minutes, too.
I can't even think of anything where that kind of speed would be useful in a home, except for making for speedier downloads of game/OS updates/installs and maybe for offsite backups.

ISP keeping up? Ha! Good one. Not like they are in a rush to cut their own throat by selling better streaming pipes. Let's also not forget the infrastructure upgrades they won't invest in either.
And while we're at it, I assume that 10Gbps is the total bandwidth available to a group of homes sharing the same channel/segment/whatever. So in the end you might get 10Gbps with very deep pockets while living in an exclusive neighborhood. For the rest of us it means sharing that 10Gbps with 10000 other customers while still paying $50 for 50mbps.
