Comcast Demonstrates Fastest-Yet Speeds Over a Complete 10G Connection on a Live Network

[TheLostSwede]

Comcast, the nation's largest gig-speed Internet provider, today demonstrated the fastest-yet speeds it has achieved over a complete 10G connection on a live network, reaching download speeds faster than 8 gigabits per second (Gbps) and upload speeds faster than 5 Gbps. At an industry 10G event at CableLabs headquarters, Comcast also showed the 10G node technology that will help power its deployments and demonstrated how its network virtualization technology will seamlessly orchestrate mixed fiber and 10G deployments. 10G is the technology that will enable Comcast and other network operators to deliver multigigabit symmetrical speeds - combined with improved latency, security, and reliability - over the connections already installed in tens of millions of homes and businesses worldwide.

For the demo, Comcast connected a 10G-enabled Virtualized Cable Modem Termination System (vCMTS) linked by more than 80 kilometers of fiber to the demonstration site. The fiber terminated into a production switch, which connected to what is believed to be the world's first fully functional 10G-enabled Full Duplex DOCSIS 4.0 node, along with a 10G prototype modem at CableLabs headquarters. Today's demonstration is a first in a production-ready network environment, showing how live 10G deployments will work, orchestrated by Comcast's Distributed Access Architecture (DAA) technology, which is already widely deployed.




"These 10G technologies represent the fastest, most efficient path to deliver multigigabit symmetrical speeds at scale everywhere, not just in select neighborhoods or towns," said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable. "The pace of 10G innovation is only accelerating, and Internet users around the world will reap the benefits."

Comcast also demonstrated how its DAA network virtualization technology will deliver not just ultrafast 10G speeds, but also greater reliability and adaptability to support a range of next-generation network architectures. The DAA demo included two key components:

• The demo showed how a single DAA-enabled vCMTS can seamlessly and simultaneously operate both 10G connections and PON (passive optical network) connections and deliver multi-gig services with identical levels of visibility and orchestration. While Comcast is primarily focused on 10G, the ability to easily blend 10G and PON provides enormous flexibility to support the widest range of geographies and customer needs.
• The demo also showed how 10G and DAA will deliver greater reliability by leveraging the unprecedented visibility the technology provides into Internet performance at every level of the network from the core, all the way to individual customer gateways.

Comcast also offered a first look at a 10G node that will become a key element of 10G trials and deployments.

Today's demonstration builds on several 10G milestones Comcast has announced over the past year, including a test in January of the world's first 10G modem technology delivering 4 Gbps symmetrical speeds.

And it only drops out once a day instead of three times a day!

And it only drops out once a day instead of three times a day!

As much as I dislike all telecoms, my Comcast (Xfinity) connection rarely ever drops and the literally three times it has in over a year, it's been at around 2am. I have a 1.2Gbps service plan (985Mbps on a 1gig LAN connections, 1185Mbps on my 10GBase-T connections) , no data caps, and it costs about $65/month... Considering how bad internet is in America in many areas, I'm satisfied. My cousin, just about 45 minutes away, only has access to DSL that's.... *drumroll*... only 1.5Mbps, that's right 1500Kbps, and in reality it usually hovers around 700-800Kbps....basically only one person can be watching YouTube at a time and you're lucky if it can sustain a 1080p stream, and the only other option are HughesNet satellite which offers 25Mbps for $50/month and has a 25GB data cap. My hope is that starlink will force some competition on the telecoms' de facto monopolies in many areas of this country.

That's a lot of words to say, "My experiences were different."

I pay for 1.2G symmetrical. I get that speed. However, I also get constant outages from the node and I'm in silicon fucking valley. They never provide anything except, "Sorry Sir, we're experiencing an unexpected outage." On a business line that they claim offers superior stability.

Our municipal ISP is slowly shutting them out of the area because Comcast simply cannot offer any better service, however that rollout has been glacially slow. When the city asked if we could have one of the 10G nodes installed, Comcast flat out refused to do it no matter how much cash was offered. When we tried to get 3G fiber from the current node, they declined to do it. They're more than happy to charge $250/m for lesser service though!

Trying to get Crapcast to do anything is futile, they will only step up when it in their best interest, and even then, it takes public outcries and/or a hanging mob

I pay $103 for, I think, 800Mbps (I'd have to look again since the last upgrade) thats all thats available so far.

 

[thegnome]

10G internet... I doubt there are many services that would let you use that full bandwidth. I already have trouble getting enough bandwidth for any downloads on my 1G conncection. And that's beside the high upgrade costs. Might be fun for businesses though.

 

[HisDivineOrder]

Comcast brags about super speeds, but doesn't tell you about the drops they experience every so often because the modems are garbage or the cap that makes all that speed just a race to a higher bill.

Awesome, so customers can hit the 1TB a month cap even faster now, sweet!!

It's 1.2TB, well, at least in my area.......still pathetic, though.

Century Link has come into my area with their fiber - offering up to 940Mbps up/down and I think unlimited data. I'm just not sure about how their service actually is. I don't like Xfinity customer service and I hate their data cap, but at least I can say is that their service is almost never down in my area. I can recall maybe 3 times service was down in my area (one was due to a construction crew cutting through the cable in my neighborhood and the other two were because of....?????) over the past decade.

I shelled out for starlink as DSL pair bonded was unreliable, and currently Ubiquity point to point on a Verizon microwave backed tower at 20/5 is a Hundy a month.

If I could get line of sight to somewhere with cable or other service I would install my own Ubiquity setup.

I have Century Link and i have 940up and down for 65/mo no contract and no caps. Before my new house i was stuck with comcast with caps. My only suggestion is to not use the default Century link PPPOE gateway and use PF/OPSENSE or OpenWRT.

That means the connection is over 2 miles from the CO and they never put in a Remote DSLA.M/FTTN VRAD there

 

[HDBitdata]

So nobody noticed that they failed to reach 10G speeds on their 10G debut demostration? They only got 8gbit down and 5gbit up lol. Imagine this deployed to millions of people.

 

[R-T-B]

Awesome, so customers can hit the 1TB a month cap even faster now, sweet!!

Service at the top tier speeds is now branded "Xfi complete" and always comes with an included modem rental ( bleh) and unlimited data, for what it's worth.

Attenuation can still occur on lsbbt
