Gigabit web streaming in 2016? Live tests say yes

Comcast already running DOCSIS 3.1 with employees


Gigabit network speeds over your existing internet connection are looking good for early 2016, apparently.

That's according to Comcast, whose VP of access architecture addressed the Cable Next-Gen conference in Denver on Tuesday.

Jorge Salinger told attendees that the cable giant was already testing the technology in the field, with employees given next generation modems at their homes. Those modems are running DOCSIS 3.1 - which is 10 times faster than the current 3.0 standard.

"The target for us is to be in the field establishing network readiness in 2015," Salinger said according to Light Reading, which put on the event. "Our overall goal is to be able to deploy DOCSIS 3.1 and gigabit-per-second in a broad scale starting in 2016."

That prediction gels with what Comcast announced back in January. Then, the company said it was moving forward with a new D3.1 compliant modem from Broadcom - the BCM93390 - and put an early 2016 timeline on rollout.

But expectations and real-world events often go their separate ways, making Salinger's announcement that the company is making D3.1 work in residential homes all the more exciting for gamers, those looking for 4K streaming video, and general lovers of data.

There may still be speed bumps on the way, however.

There is no certified D3.1 hardware at the moment - certification is expected to start mid-2015 - so Comcast is currently using specially modified modems.

However things do look promising, with director of network technologies at CableLabs, Belal Hamzeh, telling attendees that their certification process is "progressing well".

Since D3.1 diverges from 3.0 in that it doesn't used fixed modulation, there are significant technical and training obstacles to be overcome before a major rollout can be put in place. Salinger said that while it has started training around 1,000 of its staff, it needs to expand that to between 20,000 and 40,000 before it can push out its service.

And even though one of the big selling point of DOCSIS 3.1 is that it doesn't need a network-wide upgrade to happen, cable companies recognize that it makes good sense to do exactly that before dealing with what is expected to be heavy demand for the super high-speed service.

Despite that, Comcast is still confident of an early 2016 launch - which is impressive given that, in Australia for example, the company building Australia's National Broadband Network (NBN), NBN Co, was proud to announce its plans to offer Gigabit service a full 12 months later than Comcast - by 2017. ®

  • DigitalOcean tries to take sting out of price hike with $4 VM
    Cloud biz says it is reacting to customer mix largely shifting from lone devs to SMBs

    DigitalOcean attempted to lessen the sting of higher prices this week by announcing a cut-rate instance aimed at developers and hobbyists.

    The $4-a-month droplet — what the infrastructure-as-a-service outfit calls its virtual machines — pairs a single virtual CPU with 512 MB of memory, 10 GB of SSD storage, and 500 GB a month in network bandwidth.

    The launch comes as DigitalOcean plans a sweeping price hike across much of its product portfolio, effective July 1. On the low-end, most instances will see pricing increase between $1 and $16 a month, but on the high-end, some products will see increases of as much as $120 in the case of DigitalOceans’ top-tier storage-optimized virtual machines.

  • GPL legal battle: Vizio told by judge it will have to answer breach-of-contract claims
    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.

  • Lithium production needs investment to keep pace with battery demand
    Report says $42b will need to be poured into industry over next decade

    Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report.

    Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional pressure on supplies.

    The report, Benchmark Mineral Intelligence, predicts that demand will reach 2.4 million tons of lithium carbonate equivalent by 2030, roughly four times the 600,000 tons of lithium forecast to be produced this year.
