As someone with symmetrical 1gig and a home server…. Wtf do you do w 20gig?
Also, aren’t you going to need a rack of equipment to even use it?
.
That’s clearly an exaggeration, but 1gig equipment is often actively cooled bc it takes non negligible amounts of compute to route that many packets. I imagine 20gig router is like a small PCThe cost of the equipment is insane too. It was way too much to upgrade my switch to 2.5 Gbps for local transfers, nevermind any faster speeds.
I know many, many businesses that don’t have 20 or 10 or even 1gig bidirectional internet. This is marketing fluff/flex as they know that even if they offer it to 100% of users. Only a very select few will consume it
What kind of non-business user can even use this. Even if we assume all of octomom's kids have 3 uncompressed 4k bluray streams running each at once - that's 2.5Gbps max. And no streaming service even offers uncompressed video.
Seriously - what is the point of >1Gbps for normal use? Games? They can be preloaded days in advance nowadays. Even without preloading - it really doesn't take long to download on a gig connection.
Challenge Accepted.
You can get used enterprise stuff relatively inexpensive. By relatively, I mean that it is out of most home user budget and expertise, but within the realm of what someone who would want multi-gig could get.
In the datacenter, we stopped using 10G in 2017, and we are working our way up to 200G for servers. Virtual Machine hosts can use all of this bandwidth.
What this means is that you are going to see more 10/25/40G stuff in the used markets. A quick check of eBay and there's stuff in the $300-$500 range.
In a home situation where you only have a couple of transceivers and single default routing to your ISP, the switch is barely going past idle. Transceivers and doing stuff full table BGP routing is what makes the switch eat power. In home use, I would expect to see under 100W.
Same. And they send me an email every few weeks to see if I’ll upgrade to 2gig. I pretty damn happy with just the 1gig. I can’t imagine what I’d do with 20gig.
I mean… I’m thinking…
Would that be useful for hosting a variety of distributed services? Nah, bc the whole point is horizontal scaling. And 20gig is definitely vertical scaling, but then again, por qué no los dos?
The metaverse (lowercase m) is expected to have lots of need for extremely fast and low latency networking. Even if it’s just short bursts here or there, in a live interactive situation, you definitely want geometries and textures downloading and rendering as fast as you can possibly get them.
So maybe they’re just prepping for that, and trying to get whales to subsidize it all.
