CableLabs, the research and development company behind the evolving DOCSIS standard, announced it has completed its Full Duplex DOCSIS 3.1 specification, which significantly increases upstream capacity. The updated spec enables a theoretical peak upload speed of 10Gbps, matching the 10Gbps download capability of the DOCSIS 3.1 spec. More importantly, the update paves the way for symmetric multi-gigabit services over existing hybrid fiber-coaxial (HFC) technology.

“In the United States, more than 90 percent of households are connected to an HFC network, and consumers typically have higher download speeds than upload speeds,” said Phil McKinney, president and chief executive officer of CableLabs. “By enabling Full Duplex DOCSIS, the upstream and downstream traffic can flow at up to 10 Gigabits concurrently, doubling the efficiency of spectrum use.” In current DOCSIS networks, spectrum is typically split between the upstream and downstream, or spectrum is shared between upstream and downstream traffic.

I don't want to like this... so I unliked it then liked it again :/

I'm so pissed at Comcast right now, they have the most draconian policies.
 
And in my state, about 70% of it does not have access to what is considered a broadband connection.
 
I love the speed increase, but that 1 TB cap isn’t going to last me very long going at those speeds.
 
It's nice to know that I'm still a few dozen generations behind this theoretical throughput.
 
Is this like a if you build it they will come, scenario?

Because in my area we arent anywhere near these speeds, the top service around me is only 60mb down, maybe before I die we might have faster Internet speeds.
 
I guess if it means you choose to download MORE stuff, it would affect your cap, but otherwise I don't see how the speed of your download changes the amount of your download.
 
I have Spectrum and currently no caps. Most of my traffic is from video services (Netflix, Youtube, Hulu). I was at a conference last week and they had a guy from Cisco do the keynote - he said they have been observing an increasing amount of video traffic and thinks that this trend will continue. He thinks more people will be uploading video as well. He was talking about doctors of the future being video based. We'll see.
 
This is rolling out pretty soon. Now the speeds won't be 10gbps or anything. But speeds will be kicked up to around 600 down and 100-200 up depending on package. Should be out in some areas in the next 4-6 months. I'm happy with my 300 down but would like my 20 up to be more like 60-100 up. If I'm bumped to 600 down I won't complain about it.
 
I pay extra to have no cap on Cox. We have 5 people in the household and most watch tv or use youtube and play games online. 1TB did not cut it when they first announced the cap. They gave 2 months leeway.
The first month we were at 1.5TB. That was not going to work. Only have 300/30 connection... No Gigablast yet. :(
 
I have ATT giga fiber so gig up gig down and will say the internet at large is not ready for this speed. Most websites can’t handle more than about 200 Mb. I’ve only found blizzard and origin downloaders to even be close they can hit in the 800s. I will say it’s nice to get 40 gigs in 1 to 2 minutes . But otherwise that much speed is not needed. If it wasn’t just costing me $70 a month I would probably get slower. Another thing to note if you get AT&T fiber with DIRECTV you have no. Cap.

and here I am being happy with my 38mbps down and 3mbs up... vancouver prices need to come down :/ but on the other hand, if you don't need that fast of speed why pay for it?

Another ATT Fiber user and I also have noticed that the Internet in the US in general is no where near ready for these speeds. The download speed itself wasnt the reason I switched from Comcast, it was the upload speed that got me. I was capping my upload a lot on Comcast and now I dont have the issue at all. Basically I can download and upload as fast as the service im connecting to will allow. Almost no exceptions.
 
funny, i literally just posted this to FB after finding out that 1Gbit is available to my house....with a 5Mbit higher upload than the 300/30 I'm already on.

Comcast can't keep my measly Watch ESPN stream going consistently with 90/10 Mbps service, why would I even care about 10 Gbps?
 
One gig Internet is the fastest will ever see in the for seeable future. At What point do you think you’ll put a 10 Gb network card in your computer. Everything above that is meant for business for now.

I heard that when they said the same thing about ram and storage space. ;)
 
Lol I agree I guess my real question would not be when will you get 10 gig nic but 10 gig switch we just got one at work they start around 4000 for the lower end ones sooo ya.

We will get there but really why ... for residential use anyway.

$50/month. Only real option in this price range, but it works for me. I'd be happier with more speed for less money, but I can't do much about it. Monopoly.
My hardware is all capable of well over 700Mbps.
 
Bah, do they even have reliable cable modems that can handle that speed? The last 32x model I saw was a buggy mess a year after release (arris surfboard).
 
Fantastic, so while people would have a connection that theoretically would be capable of providing them 9.75 Gbps of sustained bandwidth, in regular actual usage the end user will wonder why Netflix and YouTube and other streaming sites can't seem to play for more than 27 seconds without buffering, got it. :D

This.
I'm tired of the small increase in speed each year 50mb->60mb which they claim is a free upgrade. Then 6 months later, they increase the price. Nothing is ever free.

I've been wanting to move to 10gb at work, but the prices have just been too high to justify upgrading.
However, data keeps growing, backups are taking longer, and the prices are slowly coming down.
I think I'm finally ready to start pushing management to allocate the funds to upgrade.

And the most important, does it have a jtag port?
 
10gb sounds good but is it stable. Ain't no good if your dropping packets and equipments crap.
 
For the low monthly price of $1999.00/mo with a generous 2tb cap! Overages only $50/tb!

Don't like that? Tough shit! We are your only option!

Eh, providers are also limited by the same speeds we are with a few exceptions and workarounds. DOCSIS 3.1 should allow them to upgrade their pipes as well. The municipal government I work for just upgraded one of its pipes to 1Gbe recently, before that I think it was a half-gig.

If you are single and only download 1 item at a time this is an issue I suppose, but if others live with you then its however many people x what they are doing. so 200Mb in a family of 4 can easily saturate a Gb connection. For reference I have a family of 4 with Comcast at 70 Mb and if steam downloads a game on one computer it can lag people gaming on others. What we would like to see is a day when that wont happen, or the download is so fast we don't care if we are lagging for 30 seconds.
 
The problem with cable upload is it's only 4 carriers on most systems. To get more upload, you'd have to move the whole system to a mid or high split which takes all new equipment from the headend, to nodes to amps. It's easier with the Node + 0 setup we're rolling out but it's a pretty massive capital investment. The downstream is a little easier with them moving from QAM to OFDM

That was a DOCSIS 3.0 modem, based on Intel's chip. The problem actually was with Intel, as any manufacturer who used that chip had the problem. The current DOCSIS 3.1 modems don't have that problem, since they are using Broadcom chips.

Having symmetrical upload speeds available doesn't mean much to me, since the cable companies aren't even coming close to offering upload speeds that DOCSIS 3.0 is capable of. In most plans, the upload speed isn't even maxing out DOCSIS 2.0 specs!
 
FYI, docsis traffic is becoming increasingly asymmetric as video takes over.
 
Huh. I have Comcast's 1Gbps service and no data cap. If you get the Gigabit Pro which is 2Gbps symmetrical fiber, you also have no data caps.
 
None of the modems available now have the capability of doing more than 2 gigabit lags. So what good does 10gig service do when the links are a magnitude smaller than the service.

Here's a little story: Recently I got an email/notification stating I had hit 90% of the 1 TB cap...this was about 4 days ago or so, so near the end of the month. As such, I stopped any downloads/tried to cut down my usage for a few days, figuring I could avoid using more than that 100 GB in a few days.

Then a couple days later I get a notification that I had hit 100% and used up my last "grace period" month. My question is, how the fuck did I use ~100 GB of data in two days with no downloads, and only minimal streaming and Netflix usage?

I think Comcast's data tracking is questionable at best. If I had gotten charged for it (which, next time supposedly they will do) I'd be calling customer support to pitch a fit. I already pay them almost $110/mo just for internet. Shit is ridiculous.
