DOCSIS 3.1 Makes 10 Gbps Downstream & 1 Gbps Upstream Speeds a Reality

[ironcerealbox]

Docsis is always maxed due to null packets . To put it simply, that way Docsis service quality is always related to HFC network signal quality and not to amount of bandwidth.

Also, all bandwidth numbers above are shared between users in specific service group, individual users will never get those speeds, though sometimes you can pay extra for qos type prioritisation to get it close enough.

Service groups (SG) usually have anywhere from 100 to 500 members/users, but it is not so strange to see numbers well above that . When SG 'actual' bandwidth hit certain threshold, that network segment usually splits, but that process relies heavily on investment plan.

Good point! Thanks for reminding us or educating us on that topic. I'm somewhat knowledgeable with network infrastructures, protocols, and procedures but not nearly enough. I'm more on the CS and computer hardware side, along with maths.

Spectrum is notorious for advertising their packages as "up to x/y DS/US, depending on availability of bandwidth in surrounding areas" - which, during the mornings and days, is great (people going to work, kids going to school, etc.) but during the evenings, it really slows down as everyone is getting online at home. I have had to adjust accordingly because of this. Sometimes, dual or triple 4K streams going on, downloads, and uploads of data to research servers is just fine late-at-night. During the evenings, forget it.

I'm sure Comcast is, probably, better in their infrastructure than Spectrum is in areas that used to be Time Warner Cable. I have heard Spectrum areas that were Charter have not noticed huge differences but for us former TWC customers, we are seeing huge changes.

The only problem i've foreseen is Comcast added a stupid 1TB Data Cap which they didn't have before

and i break it every month

We don't have one, yet. However, there is a growing rumor of a 600GB cap to be implemented soon (hopefully, IF TRUE, it is for the lowest tier package(s)). Man, I go through that in like 2 weeks! >_<

And, ja, I envy main-continent Europe, Japan, and Korea.

Cox has a 1.5tb data cap that should be enough for me to download a few games a month and stream 4K Movies and tv shows on Netflix. There over data charge is like $10 extra for 50gb extra of data so I should be ok

I rarely download games lately (PC Down) and mostly just stream

Yet I still break 1TB

 

[NTM2003]

I’m sure I will to but I ask them when they install next month. Hopefully the 960mbs will come to my area to cox does offer it but only in the cities

Man and i just bought my modem

If it is 3.1 cable modem, no need to worry. CableLabs Docsis specs are always very robust and look forward, but at the same time, backward compatibility is a very high priority. D2.0 cable modems are still deployed and used, well, at least in some environments and within certain speed/service limitation recommendation.
Worst case scenario, you will use just one OFDM block in upstream, so you won't be able to use more than 1Gbps in upload .

@Jism
It's not that simple. Different markets, different ISP cost/benefit strategy. Full duplex cable modem will cost them an arm and a leg, i guess they will be deployed for business costumer/services, prolly as a multihome/backup for HQ/branch on fiber.
Btw, OFDM block in 3.1 specs does not segregate geographically .

Also, 'hood' cabinet is a part of a long chain in HFC network, and it's not limiting factor per se, at least as long as level of network 'quality' is optimal.

I'm glad i can help, . First time poster, long time lurker, maybe even for more than a decade .

Data caps, implemented on 'fixed' broadband, are HUGE BS. Even from ISP pow. Caps completely distort process of network growth guesstimate. It is clear indicator of who is running tech in that company .
Even on WiFi/3G/4G caps somewhat 'works' just because margin of error for predicted network growth/behavior is obscured by large fluctuation in level of wireless network 'quality' .

Also, if all other types of online services (beside 4K stream) work well, it's throttling, either on ISP side trough badly implemented QOS and/or bad segmentation or on BGP/uplink towards streamer service source .

I kind of wish your wireless company’s offer home internet over hotspot from your phone for a good price a month but there so unreliable speeds because of heavy traffic the speeds start to slow down cable internet don’t do that. That I know of

It's just like wifi, there is only so much data you can cram through the air and you're sharing that with a lot of other people. Shielded copper cables though, that's a very different story, you're not sharing that bandwidth with nearly as many people and ISPs can divvy up networks to be small enough to be constrained by available frequencies. Huge benefit is that the infrastructure is already there.

Their 1gbps plan doesn't have a cap. Might be reason to upgrade.

But the price difference is to huge

$49.99 vs $300 a month

But what about the TIME savings? Those .1 sec faster YouTube videos really adds up

Man with my 200MBs plan nothing has to load. Everything just pops straight up as soon as you click on it

 

[NTM2003]

I haven’t got my 100mbs yet but i definitely know the difference from 2.5mbs DSL.
