Comments on news posted 2012-05-15 08:33:51: Many cable operators haven't deployed DOCSIS 3.0 yet (especially on the upstream side), but that obviously hasn't stopped the development of the next step in cable broadband technology. ..

Just got Docsis 3 upstream update this week

Comcast just rolled out Upstream bonding in my area this week. Had downstream bonding for a couple years. It is taking years to roll out Docsis 3. Imagine how long before they roll out any updates to it. And Comcast is one of the more aggressive providers in rolling out D3.

supposedly it's just patch for the docsis 3 gear that supported upstream bonding already.

To bad they won't start working at upgrading current plants to be 2200 mhz capable that would be an awesome thing.

Still rocking SB5100

Comcast can't even saturate my old SB5100 here in Atlanta. I'm supposed to get 12/2 service but it's more like 8/1 on a good day. I'll buy a D3 modem when they actually can provide good service... maybe by 2020 or so.

You may very well be getting 8/1 on a good day *because* of your SB5100. Buying a D3 modem will provide you with bonded downstream with four channels.

You're complaining about the traffic on a one-lane road. Move to the four lane road. While you don't intend on exceeding the speed limit, the additional lanes provide far more options...

You'll still have a 250GB cap in 2020, so what's the point?

If you owned a DOCSIS 3.0 modem, you would get the full speed of the service you paid for, because your connection will be balanced between multiple channels. Plenty of people on many different cable isp's have reported this.

Broadband really started with @Home

I seem to remember that cable modems were the first mass-market broadband. ISDN was a joke. Once @Home started taking off, DSL expansion and all the rest followed.

I found a CableLabs/DOCSIS history page here:
»www.cablelabs.com/anniversary/data.html

I actually can't remember if @HOME started offering service before DOCSIS 1.0, I think so.

Cable Broadband started with @Home and died with @Home, since Concast took over they have done nothing but limit its potential with invisible caps and now the 250GB joke of a cap. I am just glad Verizon has upgraded me to FiOS and now I have a connection that can smoke anything Cable can offer now and in the future and all with no caps, they are also standing up to the BS fishing lawsuits instead of just giving in.

stop gap

I am pretty sure this is a stop gap measure. They are looking into having the next spec look like fttp but on coax. I know they are also working on how cable companies can use fiber to the home and control it with current docsis headend equipment.

ftth is too expensive.

With the costs of FTTH, this is a much better alternative.

Cable is already able to do 100+ down (if I remember correctly Comcast demonstrated 1gps down on live plant?) Its not the capability that's lacking, its the need. 95% of households are perfectly fine with 10/1 service so investing millions for less than 5% who aren't happy with the 40-50/5ish services already offered isn't logical, yet.

The FTTH speeds dont look so impressive when you look at where cable is at when you figure the cost difference between the 2. Its only a matter of time until they increase the spectrum for the upstream. Its too noisy in the sub low band to do much more than a 64qam (which is already a huge challenge) so there going to have gain more spectrum.

Just an FYI, I have done plenty of speed tests on coax that are atleast as impressive as yours (including that sub 5ms ping time).

So you're saying Comcast is advertising something they can't deliver. I'm promised 12/2 service WITH my SB5100 modem. The SB5100 is more than capable of delivering 12/2 service, I shouldn't have to spend more money for something I have no need.

It's nice but...

...it's for the privileged few that can actually justify spending $100/month for high speed DOCSIS 3.0 service. Cable providers really need to work on bringing down the stratospheric cost of DOCSIS 3.0 service to mid-tier levels.

Re: ftth is too expensive.

Here, DOCSIS3 plans are up to 250mbps, so very easy to do 100mbps.

And the Comcast user who can't get 12/2 with a SB510x, DOCSIS3 will likely help you, it might not. The SB510x modems will only use one channel, a number of them on your node doing lots of traffic, will saturate the single channel, DOCSIS3, will use 2-8 channels, spreading the traffic out to different channels on compatible modems.

Single channel is ~38mbps, so if you have 3 modems trying to do 12/2, that will work, but there is not enough bandwidth to do 4 modems at full speed on DOCSIS2 on a node.

Re: Still rocking SB5100

Hey now, he was just offering a solution to your problem. Spreading your bandwidth over multiple channels tends to give you more bandwidth, alleviating the low speed issue you have now...but that would reduce the number of things you could complain about

Congrats, you live where most of us don't. For the rest of us, 50/15 or 105/20 (with the associated expense) are what we have to live with...with higher ping times even to the first hop *shrugs*.

You're complaining like you are sitting behind a router that can handle the traffic, but the 400mhz Pentium II that you're browsing with isn't cutting it on the data rate.

On a 1GHz system

Cable has 5.3Gigbit/s or 5,300mbps

11.7gig on 2.2GHz system.

Most people are limited by the computer hardware of 1gigabit

Re: ftth is too expensive.

Cablelabs is looking into epoc to get 10gigabits/10gigabit speeds over coax.

Unlike telephone cable , coax is not the barrier for speed. Just like fiber its the equipment at either end thats the problem.

Also they are looking into basically having docsis over fiber. This will allow cablecompanies to roll out fiber to new construction while still using coax.

The cable companies do not have to upgrade to fttp anytime soon. Heck even Verizon stopped their roll out.

Sorry, but I have a Linksys E3000 running Tomato and an i7 3.4GHz with 8GB DDR3. Comcast just provides crappy service. It didn't used to, a year ago I got great speeds. Even discounting Powerboost, I would regularly get the full 12/2 speeds. But, after their "upgrade" to my neighborhood, speed declined. Calls to tech support get nothing, as long as they can ping my modem they don't care. My cellphone is faster, and some days I do tether to the phone if I really want to get something downloaded quickly.
