AI? what are you on about.

read up on big data and ai. Understand the need for large datasets probably changing in real time then, you start to release the bandwidth issues. Will it hit our homes in the next 10 or 15 years who knows.

A Mikrotik CCR2004-1g-12s+2xs would be sufficient. I run that already. Yes you're not going to hit 20gbit over wifi, that's not the intention. A few 6E APs would probably be what people would run.

I have that kit now for my 2gbit down connection.

Ref the PCIe cards, cheap Mellanox ConnectX-4Lx cards from ebay work fine. It's cheaper to do 25G with SFP28 modules and DAC cables than it is 10G with RJ45/Cat6.

I'm happy for you, just as i will be happy with my network, enjoy

I know how AI works, but building your own AI model and training it on massive datasets isn't really a home user scenario.

quoting the 64 byte worst case figure with loads of rules is a bit disingenuous

I didn't say that this worst-case figure should be used as a guideline. There *is* a guideline, and it's called IMIX (a representative mix of Internet packet sizes), but sadly Mikrotik don't quote throughput for that.

In the absence of IMIX measurements, I think the 512-byte packet throughput is a reasonable benchmark. You're going to have a mix of big packets for large downloads, and small packets for DNS, conferencing, and other miscellaneous stuff.

I just don't see why anybody would pay for a 10G link without a router fully capable of 10G. It probably means you didn't really *need* 10G in the first place, in which case, you could just take a lower capacity link.

On mine, the vast majority of my packets go through fastpath, which makes sense as ongoing sessions generally do. I'd submit that while 512-byte packets is a reasonable benchmark for overall internet usage, home use of 20gbps is likely to be massive bulk downloads from newsgroups, steam, torrents, etc, all of which are likely to be full packets.

I agree very few people likely need 20G. Very few home users "need" 1G, and I don't "need" a motorbike but I like having one.

I don't know what other tiers the ISP offer, but there may well be a big gap, e.g. a 5gbps service and a 20gbps service, in which case I can see someone going "I can achieve 12gbps and want more than 5 so will take 20"

Very few home users "need" 1G,

Here at work with 700 pupils and 80 staff, from usage stats we don't need 1Gbps, we barely need 300Mbps. However if someone else is paying (they are) 1Gbps does make everything rather more snappy (couple of minutes to dowload VLSC ISOs? I don't mind that at all)

A shared GPON network 1G/1G on a retail contract is quite different to a business / school / charity with an office that has 300 Mbps symmetric over a leased line circuit.

I'm kind of interested in how CityFibre do their ethernet and ethernet flex services. A pure guess based on pricing but assuming that Ethernet is a spare fibre dedicated to you all the way back to the FEX with pricing pretty much the same as Openreach, and their Flex product is PON like all the residential services but if you need an engineer to attend you jump the queue.

Ethernet is a regular leased line, dedicated fibre.

Flex is delivered over GPON but apparently on a very low split ratio of 6:1 - https://www.giganet.uk/2019/07/04/cityfibre-flex-lea...

I've found most schools and offices only go with leased lines if they can't get FTTP, cable or a decent FTTC

Thanks

Not surprising given the cost difference, and that kids in school can wait a bit if there is congestion.

The issue is many schools now using all their IT in the cloud (Google, Microsoft etc) with if the link goes down they end up having to cancel classes!

It is indeed - however the bandwidfth demands are the point, rather than the bearer.... my point being that about 400 users rarely saturate a 300Mbps connection. One person could, easily, if they were downloading the internet (or all the films they could never watch)

FWIW Our leased line circuit is a fibre, symmetric, 1Gbps bearer (what specific product it is I don't know as the LA deals with that side of things) with a nominal 300Mbps enabled bandwidth... though it may have been enabled at 1Gbps for a while (cough - a year or so) before anyone noticed and turned down the wick at Christmas. On Monday it gets officially set to 1Gbps.
