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.

I reckon there could be something potentially useful... like... generating "conversational noise" for the NSA to record at 1Tb/household; that would be a useful DDoS, one that it is even legal - the NSA intercepts the traffic on their own will, I didn't asked them to.

Having a /56 IPv6 subnet, I have been tempted to write a small daemon that would generate traffic from random addresses and ports in that subnet, and if finding a similar conversational partner latch on and do full-on TCP sessions of noise. I'd QoS that locally to minimise the impact to my real traffic, while it'd still look clean on the outside. Maybe then add a switch of two to actually allow routing of real traffic over the noise, just to build a very nice haystack. Alas, I have so many other projects I'd rather spend my time working on... (and I'd still feel bad for wasting bandwidth, though it may be the lesser evil).

Contribute as a tor relay (not exit node, just a relay) - the traffic you'll generate will be useful to someone and you'll have no idea what transits you computer from where and where to.

Interesting, I hadn't thought of that possibility. Cheers!
