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.

    Whaaaaat?

    Did you read my post? Go back, and have another stab, and this time read for comprehension.

    Having said that, your response seems to show a complete ignorance of the fact that the producer needs to give *billions of fucks* about his own outgoing bandwidth, so you're clearly not thought anything through, even the content of your own outgoing payload.

    I guess I'll have to be explicit: The only thing about me that a producer needs to think about is my bandwidth with respect to them. As long as the absolute upload speed I allocate to them and the absolute download speed I allocate to them are above the two minimum numbers required, they don't care if I'm using 99% of my bandwidth, or 50%, or 1. The only time they'll get even remotely interested is if their content is 100.1% of my bandwidth.

    Again, the producer doesn't care about my ratio and probably has no business caring... unless a fucked up ratio imposed by my ISP interferes with them delivering, and thus selling, content to me.
