The last spiderman was something around 200gb, and I think call of duty is even larger, but i don't play that. Their point still stands though: the download servers bandwidth usually throttles below gigabit, so it's gonna be hard to saturate that line today

> The last spiderman was something around 200gb That is not true at all? Spider man was like 70gb , miles morales was like 40gb

i could definitely be wrong, I thought i made that clear from my phrasing. A cursory google does seem like it was closer to my number then yours though.

  Call of Duty Black Ops Cold War Cross gen bundle / Ultimate edition - 283.5 GB minimum
  Spider-Man Miles Morales Ultimate Edition - 170.5 GB minimum
  Hitman 3 - 105.1 GB minimum
  Destiny 2 - 101.1 GB minimum
  The Last of Us 2 - 93.37 GB minimum

Because you have a single copper pair/coax cable with a finite bandwidth on it, and making a choice about how to split it. Eg, your tech and cable can support 40 Mbps. If you split that 20/20, your users will have trouble watching 4K video that wants 25 Mbps. Change that to 35/5, and for most people it'll actually work better. This issue goes away eventually as you either get a fiber for each direction, or you can ju…

Why isn't the splitting dynamic, according to need?

Well, that exceeds my knowledge, but my guess is that it'd be very tricky to accomplish.

You have one cable, a given frequency may go in one direction or in another. Both sides have to agree on what it's being used for. You'd need a communication channel between the ISP side and the client side to constantly negotiate, and that negotiation would take some time, so such a mechanism would have some latency to it, with possibly weird effects on things like online games. You could get weird behaviors where some particular pattern of traffic would result in the connection readjusting itself just wrong on a regular basis and result in hordes of angry gamers.

I think it's reasonable to guess that ISPs targeting consumers have no interest in monitoring and troubleshooting such a thing when they can just set a fixed split and be done with it (and ask the customer to upgrade to a bigger plan if it's not good enough), and ISPs targeting enterprises have no need for it.

Edit: And there's the issue of how you sell such a thing. It's a system that readjusts itself automatically based on some arcane magic and may work differently from one day to another. How do you make any reliable promises about it?

The challenge with anything above a gig is the LAN. 10gig+ switches and SFP modules are expensive for consumers. So is the client hardware. We use thunderbolt 3 on our macs with ATTO Thunderlink to get 40Gbps locally and they’re kinda the only option and their hardware is bulky, expensive and their software sucks.

Also config on Mac is awkward.

There’s also some weirdness when you upgrade to that speed into a backbone with sub 10ms latency where, for example, Teamspeak’s servers kept booting us because a security mechanism thought we were doing something naughty. We had to use a VPN to connect to add back latency.

25Gb/s is just overkill for residential use. It's really cool that's it's available, but I fail to see a use case over my 500Mb/s home connection. Even for the servers that I manage and that are bandwidth-heavy, 10Gb/s is way overprovisioned for now. WiFi goes up to 1Gb/s, if you're lucky. Sure, some WiFi-6 APs have a 2.5Gb/s connector, but that's not what you want or need, unless you're a high-density enterprise. Wi…

25GB/s is overkill, and 640K ought to be enough for anyone. Those quotes age well.

you mean 640GB of RAM ought to be enough for anyone. 640k wasn't cutting edge at the time, it was meant for personal computers.

I hate asymmetric connections. You get gigabit download but something stupid like 20-100 Mbps upload? Just why... Upload speed matters just as much as download these days.

If you split that 20/20, your users will have trouble watching 4K video that wants 25 Mbps. Change that to 35/5, and for most people it'll actually work better.

Oh yeah, missed the "cable" part. But I've seen the same thing with fiber in the UK and Germany. So the ISPs upgraded to fiber but kept the old (very) asymmetric speeds... I mean, at least have it be something more reasonable like 1000/500 :)

But I'm spoiled, growing up the only ISP in town spoonfed everyone higher and higher speeds even though no one asked for it. They're laying fiber to villages seemingly just 'cause. People are choosing 4G over fiber because it's cheaper (even though data is limited), go figure.

Well, actually there was a bit of government initiative (with no funding or enforcement) to boost the IT sector. The US would benefit much more heh.

On behalf of all tech-minded Americans, I would like to say... I hate you. I just got a notice in the mail that my ISP is "upgrading" their network so now I can pay $200 USD/month to get a whopping 2gbps, which I actually thought was pretty amazing until I read your post. So, thanks. In all seriousness, congrats! You made a good case for why one would need that much bandwidth. Also, we need to catch up here. :)

On the other hand, try making 10-15k/month in europe in a regular tech job, esp. with little experience (0-3yr). It's orders of magnitude more uncommon than doing so in the USA. So bring all the hate :)

That’s all very well if you have a tech job. If you have a low paid job you’re utterly screwed in the US. I’d rather make less so my fellow citizens can live a decent life too.

An alternative to the Thunderlink is a TB3 -> PCIe expansion box. Then you can use whatever card you like without need for additional software.

I had 10gb internet on what was essentially a shared connection when I lived in Zürich. That, along with a surplus server I literally housed in my shoe closet, gave me the firepower I needed to prototype out something that led to two research grants which now employ myself and a new PhD student. We discount technological investments like this as being “too much” and “unpractical”, but we forget that, even if it only…

Being from a third world country, I completely agree with you on how technological investment can change lives. Even a low speed connection in a rural zone can achieve wonderful things. But I really wonder what was your prototype that needed that speed connection and that wouldn't work with something slower. Can you share, at least vaguely, what was your work?

I’ve never heard someone call their own country a “third world country”. Out of curiosity, which country are you referring to?

As someone shopping around for a FTTH offering (to get out of my current DOCSIS plan) how can I figure out which routers are compatible with the ISP's GPON?

I've had phone calls with them and the support/sales reps have no idea. They provide their own router+AP box that takes the fiber and spits out WiFi and Ethernet, but how would I go about replacing that? Their hardware is obsolete, insecure, outdated and just all-around poor! I know I could set it to bridge and place my own router in between, but I'd love to just replace their box instead.

As far as I could figure out on my own, the best bet would be getting a EdgeRouter X SFP and then plugging in a compatible SFP module. Is that right? How would one figure out which SFP module to buy?

On top of all that: do ISPs run proprietary handshake stuff on top of it, where even if the physical connection is correct, the ISP refuses working with your box? or is it just like the old ADSL days when all you needed was just a PPPoE stack?
