Having your uplink faster than all your individual ports in a network helps prevent any one port from being able to saturate your network.
I work at an ISP that within the last year started selling 10Gbit symmetric, and we all sorta know there's not a huge use for it - yet. It's not really an issue for use to justify though, we don't charge any extra for it, it's all $40/mo and if you're in a new area we're building you get 10Gbit instead of the old 1Gbit at that price.
If they kept the same price then the total cost to the end user would be ~$70 for 10G. Which is less than half of the cheapest option available.
Still very worthwhile to not have to talk to a Telco, but I had to rent + use AT&Ts garbage router because it did some proprietary negotiation step (With the ONT? There was a blog post where someone reverse engineered what was happening).
Now I'm in a smaller city and Sonic claims they have plans for us some day. For the time being, it's the Comcast nightmare.
Edit: and AT&T fiber was asymmetrical. Disappoint.
Still, like you noted, not having to deal with AT&T is a great selling point to a lot of people, and we're known for good support, so I'd like to think we're providing as good a service as those people can get until we build out our network in their area.
We have aggressive plans for the future, so I hope we're in your area sooner than later. :)
I imagine it's easier now than it used to be to find some areas with good beauty and above ground infra (poles) that have space, and make a business plan and point at others that are doing it successfully as justification.
Or maybe we'll be there in a few years. At the rate we want to expand it's not impossible. :)
I think it's way too rural at this point however, given that I am technically in unincorporated area.
EDIT: USA, CA here. sonic.net. $40/mo with 3 free months. They'll pay up to $200 termination charges. Not affiliated with them.
From a switch perspective, it makes more sense to carve out 4x 25G ports vs 4x 10G ports if you have 100G switches. In a single rack unit you can fit ~32 100G ports, which can then be broken out to 128x 25G ports. That’s more port density than a 1U 48 port 25 switch/line card.
I used to design 2D graphics accelerators, one thing we learned was that perceived performance is not linear, in reality there was a performance region where people would always crave more, and another where things were fast enough and people were happy but wouldn't open their wallets for massive increases .... at that point 10x seemed more like 1.5x) - I suspect that something similar applies to home net performance too
Going above 1 Gbit/s can have (very limited) practical sense because you can hit that with e.g. Steam downloads, changing a 5 minute wait into a 3 minute wait. You can also basically stop caring about QoS on your uplink once you're at 1 Gbit/s with one human user, or anywhere past 1 Gbps with more than one human user.
For running cables, seriously consider fiber. The hardware isn't as expensive as it used to be, and it solves a lot of problems: You can (based on common sense, not sure of your building code) stick fiber in power conduits since its non conductive, you don't have to worry about potential differences etc., it's thinner (easier to hide/more wife-compatible) and once in place, you will be able to use the same fiber for higher speeds just by swapping the SFP's at the ends.
Init7:
1/1 Gbit/sec CHF 64.75
25/25 Gbit/sec CHF 64.75
It's the same price if available.
Wifi6E is around the corner for >1GbE wifi.
25Gbps is for multiple transfers from multiple sites to multiple computers. For example I transfer large files for work (up to 100 GB) from multiple sources and it takes a long time and consumes all the bandwidth in the building. If I download at lower priority (implement some QoS) then it takes even longer. I can see 25 Gbps eliminate the bottleneck and allow everyone in the building to have their regular use (video conferences, movie streaming, gaming, whatever) without me impacting. I would never use more than 1% of that bandwidth on average, but I would peak more than 1 Gbps quite often. Yes, 10 Gbps would be more than enough, but if the cost is the same then 25 Gbps seems more future-proof, at a cost (SFP28 equipment is much more expensive than SFP+).
I have to schedule it all to run at night because it will saturate the network during the day otherwise.
I have 1Gb/40Mb @ $100 internet for reference.
What a pointless question. I wish people would stop worrying about this instead of simply making it possible, so we can figure out what to do with it.
We got 1Gbit in 1999-2000 at work. Upgraded to this crazy IBM standard for wall sockets. Turned out to be unnecessary. We had 10Gbit at work in 2006. When I switched to one of the 'big internet companies' in 2008, every fucking server was supposed to have 10Gbit. In 2013, every fucking server was supposed to have 40Gbit.
We're now in 2022. 8 years later. And people argue about 25Gbit at home.
Ḯ'm a bit ashamed.
Secondly - as a person living my whole life in IT - both passion and professionally - I have no idea what would 25Gbit be good for. I’m currently paying about $80 for symmetrical 1Gbit fiber and have the option to upgrade to 5Gbit for about $180 but it seems so pointless.
Here is the reasoning behind my grumpy opinion:
1. Living in a home with Cat5 throughout so the best I can do is to route 1Gbit. Running cables in multilevel (American) homes is a major PITA.
2. My Wi-Fi (802.11ax) is heavily affected by homes around me so only one AP can run with 80MHz channel width and the rest is 20-40MHz. Throughput ends up being somewhere between 150Mbit-500Mbit, depending on where you are.
3. I have a few smaller servers running ..stuff. The trouble is not about server performance or bandwidth.. it’s about reliability. Running any business on consumer line (in the USA) is just signing up for trouble. (Eg. “Is your line down because your modem received a fault firmware? No worries, the tech is going to be there within next 4 days to check your cables…”).
4. Things like game downloads on PS5 .. yes, they are amazingly fast (even on 1Gbit. They install faster from internet than from the built-in BD-ROM). But many games need to also “install” (whatever that means on PS5) and that takes 2x the time of download anyway. I can live with that once a month.
5. Big fan of streaming services, however many providers limit bitrate on their side so I am still watching the sometimes blurry 4k …
Back to original question and with genuine curiosity - what is 25Gbit for???
