Docsis 3.1This looks to me to be the cable industries answer to google fiber | |
|

Re: Docsis 3.1If it gets out of the lab. I'm sure the research could always come without Google but will they deploy and compete with Google on price. I would guess if Google and smaller Gbit players didn't come into play they wouldn't have bothered. | |

Like the cable industries would even remotely get close to these speeds any time speeds. Well maybe if we were out of the states sure but the majority of the people on the site are not. Maybe in areas where google fiber or other 1gbit providers they might be offered at 10 times the cost. | |

In the couple cities Google Fiber is offered in maybe. But in most of the US, this is to compete with FiOS and other FTTH networks. | |

Wiring our offices with 10 gbps ethernet...over fiber...just throwin it out there. | |

said by kc9sqr:This looks to me to be the cable industries answer to google fiber Nope, if cable companies came close to Google and/or Fios speeds, Google and Verizon were smart enough to invest into their networks to turn up the speed even higher to leave cable in the dust even if by some miracle cable actually maxed this out. | |

I think this was in the works prior to Google Fiber. There are other countries that use the DOCSIS specifications and they were asking for a response to the FTTP and FTTH in their countries. The problems that exist in deploying the DOCSIS 3.0 upstream led in part to calls for a radical overhaul of the DOCSIS specification. DOCSIS 3.1 should really be called DOCSIS 4.0 considering the significant changes from DOCSIS 3.0. | |

More like the cable industry's answer to collusion with Telcos to provide cellco backbone more then anything (at metered rates). If you think this is going to give you gigabit speeds under $100 to residential customers anytime soon, your mistaken. You may not even see anything offered under D3.1 hardware until late 2014 and it will be unaffordable as can be. It could take another 4 years for 300 megabit speeds to be common and affordable at the rate of "innovation" let alone 500 and 1000. | |

hardly. cablecos aren't going to bastardize their LUCRATIVE biz products by offering google fibre type speeds.
more it'll be used to load nodes even heavier. | |

I'm thinking......this is why the ComCast network guys are pushing D3 equipment so hard, because D3 and D3.1 can easily co-exist and 3.1 early adoptors will have speeds available only to FTTH today, in just a couple years, over the HUGE cable footprint.... perhaps before Google can finish their limited build outs. IMHO covering MOST areas of the country with 100/20 is far more important than offering a few million symmetrical Gb service This offers high speed to most and ultra high to those with the budget for it, within a short time frame. | |

AwesomeCable is really stepping up to keep pace or exceed fibre at a lower cost. I think Google's move is turning out to be brilliant with FiOS shutting down expansion and regional players stepping up....
Coax as the last mile is just proving to be a great technology.
The big loser in this will be DSL. They will need to do something there but for now IF you can get a decent connection it works. Maybe fixed wireless fixes the problem.. | |

Re: AwesomeSure they are as we wont seen awesome speeds at a fair prices in ages. | |

There are technologies out there to squeeze more out of copper twisted pair, but AT&T, and to a lesser extent Verizon, are *cheap*. It's nice that cable is stepping up to the plate, let's just hope that caps and other "network management" practices keep up with the pace of advancement as well. | |

The technology to bring VDSL2 triple play services, with a 100Mbps symmetrical internet connection, to every house with POTS exists today. The telephone companies have to be willing to make deeper fiber optic installations into their networks. That action would satisfy an enormous percentage of current DSL users for a long time. For many premises with POTS service capabilities, this can be done without ever going onto the subscriber's property. To get to 1Gbps or 10Gbps in the future would require a genuine FTTH or FTTP run. But it would be fairly short addition, since the previous installation of the VDSL2 services should get the fiber within 100 meters of the premises. | |

Coax is "working" but not "great". 10gb/s will be consuming near 1/2 of the possible bandwidth of the coax and it is not a simple nor cheap upgrade.
Comcast has paid more upgrading to DOCSIS3.0 than the cost of upgrading to FTTH.
By the time this 10gb coax starts making its way into the market, we will be seeing 10gb fiber, which is a simple upgrade.
Just wait for the 100gb and 1tb fiber. Probably 15 years from now. They already have fully working prototypes of cheap 2tb/s fiber links that are only pennies to create.
DOCSIS3.1 is probably going to be something like a $10k head unit, when fiber will get 1tb for effectively free.
Coax is going quite further than I thought it ever could, but it is already more expensive and slower than the fiber alternative. | |

Re: AwesomeI highly doubt Comcast's D3 upgrades were more costly than running fiber to each home. If anything, it was very cost-effective, especially with a modular CMTS and edge QAMs.
I also don't think you'll see 10gbps fiber to the home anytime soon. A lot of providers have just rolled out 1gbps infrastructure and that will be meant to last for a number of years. You will only see 10gbps when greenfield deployments begin using it, and we have yet to see a single 10gbps residential deployment.
The existing providers will wait awhile before upgrading, they still have to get a return on their original investment, and these investments aren't cheap. | |

Re: AwesomeIt was probably a bigger cost going from 1 to 2... since there were "problems". 2 to 3 had fewer problems and cost overruns (which was a requirement of the cablecos). Let's not forget there were COMPETING non-standard cablemodem modulations such as Narad's patented modems promising speeds up to 1 gigabit. Nowadays they're entrenched in doing FTTX networks. IIRC Comcast spent btw ~23 and 65 billion dollars on D3 over the last 7 years servicing MILLIONS of customers.
They are probably going to get 10 years out of 3.0 (2016/7 phaseout) since it was deployed late 2006 at the earliest.. we're in year 7 now (yes, mainstream availability was probably a few years later). Much more depends on what Telcos Verizon and AT&T do. Google isn't yet a threat, except in the PR world as having the fastest speeds at the lowest prices. There isn't much proof that Google's deployments have shifted timetables for docsis or fttx deployment much. I'd like them to breach a "sensitive dense" market in the northeast before coming to that conclusion. | |

Re: "Cornerstone"...Forward error correction? Isn't that going to raise ping? | |

Re: "Cornerstone"...It probably will, but what applications will be so severely impacted by the increase that it becomes intolerable to use the application. Streaming of live video? I think high quality buffering takes care of that. Video or audio conferencing? We survive with Earth orbiting satellite linked conferences today. Remote operation of machines? We manipulate rovers on Mars with remote command procedures. Gaming? There are some gamers who will testify under oath in open court that they can use video games successfully with satellite ISP services. Isn't this similar to the theoretical effect ECC RAM has on computer performance, compared to non-ECC RAM? | |

speeds of 10 Gbps and upstream speeds of 1 Gbps...and 2GB caps. Wow! I can't wait for DOCSIS 3.1, so I can reach my limit in less than 2 seconds!! | |

Re: speeds of 10 Gbps and upstream speeds of 1 Gbps...Rogers Cable in Canada had Ultra-Lite package with a 2GB cap until the entire package was phased out in favour of a more expensive "Lite" with its 15GB per month.

While at AT&T...They are still using DSL, technology which is already decades old... I'd be surprised if they are providing 100mbps+ in most areas. | |
