content: 10GBASE-T Ethernet ports are finding their way onto domestic computers. For example, '10G' is a plus $100 order option at the Apple Store. One question though; is anyone fully leveraging the stupid-fast speed of 802.3an/10GBASE-T in a [non-enterprise] household environment? And if so, what are you connecting this too? Did it cost $s to upgrade your network devices and cables?https://en.wikipedia.org/wiki/10_Gigabit_Ethernet

content: Depends what you're doing in your home, but 10G is slower than the read/write speed of a mediocre SSD these days, so if you're using one PC as a file server for another one (or have a NAS) you could saturate that easily enough.The fastest home internet you can get -- at least in my nearest town -- is 1 gig, with actual speed in the mid 900s. So if it's just for sharing internet then 10 G is not needed at present.

Server's need to be 100G monsters just to keep up with the packets.Quote from: brucehoult on April 02, 2023, 11:32:53 amA motivation for me to pose this question is a networking speed freak who believes 10G is NOT fast enough for his 4K TV on Netflix! His TV is a 58 inch juggernaut and thus, it needs more speed because it is abiggerscreen. Guy's like him are a gift to the marketing suits in marketing suites.The only 'domesticated' use case for such bandwidth is a $10,000 MacPro video studio, with 8K video stored on a SAN/Raid array loaded with M2 EVO ssd modules. But outside of the Hollywood hills, there is little justification for this level of investment. Maybe in the near-instantaneous future world of the Metaverse 10G will be 'bufferingly' slow, but for now, even inside the enterprise, it's a too much speed for desktop users.btw Myfastestoutbound-upstream link is a mere 100Mbps on a 330Mbps FTTP link. When I started networking, 1Mbps over coax was regarded a top enterprise level speed - and was priced accordingly.

content: I have two 10G networks in my house, both for storage. One is for storage replication and VM migration traffic and only covers 3 nodes in a single homelab rack. The other connects the storage arrays to a 10G switch with just 1 10Gbps client and a 2.5Gbps switch for our family desktops to connect to the storage.None of that relates to internet, which I have only 300 Mbps down and 20 up.2.5 and 10 Gbps equipment is fairly cheap now. It lets me use a single highly redundant and backed up storage array on all our PCs without it feeling super-slow and just have a smallish NVMe local volume on each PC.

content: On workstations a 10 GBit/s port is beneficial when you have to push lots of data over the network to a NAS or similar storage unit. This can happen for backup purposes (and not to overesxceed the backup window) or if you are working with photo editing or video cut, where most of the data reside on a NAS or similar server, or second workstation.But: To do this, you need stable switches- the ordinary 500$ halfmanaged switch can also go into hiccup due to small buffers.

I deliberately wired my house with Cat 6 cable knowing that I would be upgrading to 10 Gig at some point. I ended up doing that a few years ago.I don't use it to its maximum advantage but it's good knowing I have the headroom should I need it. I was finding I was maxing out 1 Gigabit quite often, especially when dealing with large files on my NAS.

content: I have 10G LAN and WAN at home. Other than special cases, for home use, it only matters if you have a reasonably fast NAS and/or 10G+ WAN (Internet) connection.At the moment, I have one all 10G, one hybrid 1/10G managed QNAP switches, two 1G (HP and Cisco) managed switches and a Cisco AP. Although QNAP would not be my first choice normally, it is the most quiet 10G switch I tried so I keep it. I have CAT 6 cabling inside walls, and it works fine. DAC is an easy solution for short distance and SFP+ switches are cheaper and more quiet but ethernet is still more flexible. Having a switch with at least a few dual personality ports is nice to have.

content: If you have only short runs of ethernet cable <= 30m good old Cat5e usually works also fine with 10GBASE-T. Alternatively there's 2.5GBASE-T and 5GBASE-T in case you need just a small boost. Beyond that I'd go for glass fiber anyway because of less trouble (high speed ethernet can be quite finicky about TP) and the upgrade path.

I wasn't exactly paying attention at the time, but I imagine vendors hedged their bets and had hardware on the market, not necessarily on the shelves at your local PCWorld, up to a year or two prior to standardisation.As is usual with networking standards, it takes a while to filter to consumer use - we've had 10GBASE-T since 2006 and the fibre standards since 2002, but almost nobody uses it yet because they don't need it. Back in 2000, most people had precious little need for anything faster than their 56k modems. Meanwhile, in the backhaul and server world, 40Gb got old a few years back.

A few computers are connected to it, and it currently has two Linux VMs running too. Not too shabby, all things considered.I work on a rule of thumb that a 1000 Megabit link can sustain 90 MegaBytes, so 10Gigabit can handle 900 MB/s. I also run jumbo frames on machines with 10Gb installed, which helps reduce overhead. All the computers are SSD based.

No fancy cabling requirements, cheaper PHYs, lower power, and still multiples faster. 2.5G is starting to be widespread in home networking equipment. If you're going to buy 10G ports in your home gear, I'd make sure they also support mGig (it is a much newer standard, despite being slower, so 10G doesn't imply 2.5G or 5G). 10GBASE-T kind of sucks as a standard.Either way, storage is really the only typical use case, and even there, most home users aren't moving large files around on the regular.

If you have a local file server and either multiple wired clients or a single client with a 10 G nic you can easily can easily use that speed. And multi gigabit internet options are... Not super common but not exactly rare either.Do you "need" that? Depends, but probably not. But it's definitely possible to use that bandwidth with relatively common hardware.QuoteWhat level of investment? 10GBase-T NICs are under $100 and switches < $50 / port. It's not as cheap as 1 Gb networking equipment but it's not a huge premium to build a 10 G network. I think that if you are building a network that will have a home file server you should strongly consider 10 G.QuoteGood for you.

Commencing this year, NBN are already planning to expandresidentialfibre services beyond the 1 Gigabit limit.Consumer routers such as those made by Asus and Netgear are already offering 10 Gigabit ports and 802.11ax Wi-Fi is already capable of saturating a Gigabit link.

So you'll see an average of 320mib/sec but it's really 370mib/sec with pauses for the track changes.You can saturate network connections much more easily with SSDs though, SAS comes in a few speeds and is usually dual connector - so SAS 12gbps (bit) (gen III - we're on 24 which is really 22.5 in main deployment - but most drive stuff is still 12gbps max really) will give you 24gbps per SSD (both connectors) - now you can saturate stuff.And the big proper enterprise SSDs are your best chance at them sustaining that performance too.

Where it really becomes useful is where you have multiple clients accessing a single resource (or you want redundancy in your links).

Call this queues, flows, channels, threads, all are more or less about the same topic. If you use SMB for example, it is normally single threaded, hence it is hard to reach 10G depending on the NIC using SMB. SMB v3 brings multichannel support but it sometimes does not run properly out of the box. All of these high speed network tech is mainly for concurrent access, so increasing the capacity of a single pipeline (from a single NIC of PC to another single NIC on a NAS) becomes more and more difficult after a point.

The wired network has switches that route the traffic so transfering between two machines doesn't bog down the rest of the network. For the average consumer it's probably not noticeable but if you're copying around tens of gigabytes of video files or whatever it becomes very obvious.

Like with everything, if you invest a bit of money in proper gear (not those stupid consumer "mesh" products), you can actually get pretty amazing performance, even in RF noisy environments with a bit of tweaking. You'll notice most consumer devices, they like to default to channels 36 to 48 and sometimes around channel 155 down the other end of the 5 GHz ISM band. They often avoid the DFS channels altogether, even if they are better.For my set up at home, I have two internal access points (Ubiquiti U6-LR) and one outside access point to provide 5 GHz coverage throughout my backyard. I use channels 106, 138 and 155 respectively, as there are no other networks on those channels. To avoid weather radar forcing your access points to jump to a non-DFS channel, jump on your local communications authority and search their database on any transmitters within 100 kilometers on the same channel(s) you plan to use. In Australia it's ACMA and you can do a frequency range search online:https://web.acma.gov.au/rrl/assignment_range.searchI actually switched to Wi-Fi on my main TV as the 100 Mbps NIC was getting overwhelmed with some of the 4K content coming off my network (which averaged at 110 Mbps).

Switching happens at OSI layer 2, while routing happens at OSI layer 3. A classic ethernet switch (or bridge) switches ethernet frames between segments at the data-link layer. An IP router routes IP packets between networks at the network layer. The IP packet is stacked on top of the ethernet frame. Or in other words, the IP packet is the payload of the ethernet frame. A so called L3 switch (L3 for OSI layer 3) can do both.

content: Quote from: madires on April 06, 2023, 08:46:36 amI didn't say you are wrong."routing" and "switching" are words being commonly used to signify a work done by routers and switches. But in English language "routing messages" is what mail server does... And it is not network device... Word routing made sense in that sentence despite being "nontechnical". That is my point.Another point is that when discussing something there is no need to always go into details. Quite the contrary, it is an art of saying only necessary to make it quick and efficient.Otherwise we might start always discussing that there are hubs, bridging, routing, store&forward switching, cut through switching, asymmetric switching, spanning tree protocol etc etc...Important part is that usually when using switches, switch exchanges data based on MAC of network interface on devices connected, while router makes distinction between subnets and decides on packet transfer decisions based on IP address of the host. Once packet arrives at destination subnet (by whatever means) then final L3 to L2 resolution is done (via ARP) and packet reaches it's destination. Also distinction is that switch has switching matrix that allows paralel (isolated) connections between hosts that serves to increase performance.L3 switches are intelligent enough to keep both IP address and MAC address tables directly so they can do switching by shortcutting routing. Also no difference logically, just much faster because it uses parallel switching matrix instead of serialized traffic through router interfaces....As for other L3 protocols, it's been decades since I worked on anything else than TCP/IP so I simply ignore them in general conversation. You are, again, correct, but it doesn't matter. For all the practical purposes if someone asks you about networking today, it is going to be TCP/IP..Best,

Switches exchange data when negotiating links and other network related things, like STP.Quote from: 2N3055 on April 06, 2023, 11:13:04 amFor routing vendors implement a routing table which contains all the routing information (RIB) and a forwarding table (FIB) which is a list of destinations and their corresponding egress interfaces. The RIB can contain inactive routes (known, but not used because there's a better route). The active routes are put into the FIB. Since routing is a lot of effort vendors came up with ideas to simplify the routing process by making it more like switching, e.g. by creating hashes for flows and using a special table which is faster/shorter than the standard FIB. Cisco's CEF is such an example. These techniques are also implemented in ASICs. But you can't switch IP packets as simply as ethernet frames. Maybe the router has to fragment IPv4 packets or has to deal with IPv6 option headers. This leads us to MPLS which tags IP packets (also other protocols) with switching labels to allow intermediate routers to switch traffic instead of costly routing.To give you an idea about the scale of ethernet switching and IP routing: A standard inexpensive SOHO switch chipset usually has an 8k MAC address table. A full IP routing table has currently 950k IPv4 routes and about 150k IPv6 routes.

content: PON and GPON are standards made by ITU, the telecom industry. It's all made for feeding commercials and dumb TV content to as many users as possible, disregarding their ability to send data back. So the connection is shared among users, often passively and in most cases asymmetric. This saves some fibers, but the equipment is proprietary, expensive and there is a high threshold to upgrade the equipment. Later GPON standards are better, with better upstream speed, but if you have a small village on PON (typically restricted to 100/30 Mbit per user + bandwidth is shared!), you are lucky if they upgrade it in 20 years.I work from home and would hate having a restricted upstream. Luckily we have an ISP that uses standard IEEE ethernet switches and none of the ITU crap. So I have the option for 100/100 Mbit or 1000/1000 Mbit over fiber (and options in between). Higher speeds than 1 Gbit aren't on the table today, but if you pay... they only have to change two tranceivers and your home fiber terminal. Might be a matter of time.IEEE standard equipment is the only true networking and Internet equipment. PON and GPON is just disguised TV on life support and a surrogate for true end-to-end Internet. Engineers stick to IEEE standards.

It's more about saving the number of ports and PHYs you need to service the customers. Every classical Ethernet port requires its own switch port and own PHY, and this requires more physical space, more optics, more power, and more capacity in the switching backplane, which all costs fairly substantially at scale since we're talking about like 16:1 or 32:1 here.XGS-PON (10G/2.5G) is widely deployed here and the ILEC is selling 1000/1000 service, and I have not seen any significant reports of congestion, and based on my experience in consumer ISPs, I find the risk of it unlikely. They are running 16:1, so it isn't really much of an oversubscription ratio. Upstream of the PON the oversubscription ratio is quickly going to increase.Reality is that actual traffic patterns of residential users are still highly asymmetric preferring the downstream direction, so that is what ISPs are optimizing their networks for. It has nothing to do with TV, especially since the majority of ISPs deploying PON come from the telecom side, not the cable TV side, so while they all have TV offerings these days, it's not their heritage nor that significant a part of their business.

I have seen bad networks around by the big ISPs.There are lots of smaller fiber cooperatives around here that were built 15 years ago when the big operators removed their copper and offered only 3G/4G instead. All of these countryside and small town networks were built with network switches, AFAIK. I've some insight about ten such networks built around here in different towns. We tried to start our own fiber network in my village also; we were verbally threatened by the then local old telecom ISP; ultimately we didn't get enough interested users and didn't start digging. Fiber has become so cheap, so you don't save anything with PON, especially in rural, more widespread networks. Big ISPs might have easier deployment with PON in big cities with lots of departments.

There hasn't been a lot of development in small-scale PON (though there has been some), so it doesn't really start to make sense until a certain inflection point is reached that I'd guess is around 1000 homes passed. Many of these community ISPs are grassroots efforts, and often start at very small scale. It definitely doesn't make sense to run a PON shelf that can service 1000s of customers and costs 10s of thousands when you're only passing 100 homes and could do the job with a cheap 48-port switch. It's also much easier technically to get going using classical Ethernet, and more people understand that stuff, know how to source the equipment (good luck getting a vendor to return your calls about buying a single PON shelf, never mind the contract for management software etc. etc.), understand the automation options available and so on.Both ways are doable, and can be done profitably, but PON is definitely more efficient at the scale of a major ISP.Whether it offers a good experience is more down to competition and business decisions than the technology, and I guarantee that if your experience sucks on PON it's going to suck on any last mile technology.Big cities and apartments are actually the one place where classical ethernet can compete with PON because you can home equipment at the building itself and cabling is relatively trivial.

content: An ethernet switch does it too when it doesn't know yet how to reach the destination MAC. This is the 'U' (unknown unicast) in BUM traffic. It can also be leveraged for attacks, e.g. MAC flooding.WiFi is unreliable by default because is uses ISM bands. At any time a neighbor can plug in a new gadget which occupies an ISM band, forcing you to change channels or the band. The bands can become so crowded that you barely get any usable throughput. And you can't do anything about this as long as the devices involved adhere to local radio regulations.

If you are using Microsoft Storage Spaces then forget performance.Quote from: madires on April 03, 2023, 01:32:47 pm2.5GBASE-T and 5GBASE-T might be acceptable in some environments, like Windows only, however driver support is bad and even Intel's 2.5GBASE-T solution has problems.

content: I've done this with two low end servers with 10GB SFP+ on both ends. OS was Ubuntu Linux.Connection was with optical fiber. Created RAM disk on both sides and measured the transfer speed. The best I've seen was 3GB and only briefly. Average was about 2GB.Whether if jumping onto 10GB or not depends on rest of the network. If you are using good servers, perhaps. But in my case, it wasn't worth it.

content: I've recently rebuilt my homelab. It is now a Proxmox cluster with Ceph distributed storage, all running on 3 Intel NUCs. I wish NUCs had SFP+ because the Ceph cluster network would definitely benefit from 10 Gbps. Instead, each NUC has three inexpensive USB3 2.5GbE adapters that work fine.OP, try to avoid 10GBASE-T if possible. SFP+ might be more cost-effective on the used market, and it's also more energy-efficient.

content: At home I run 10GBASE-T between my main desktop, main rackmount server which (among other things) is my home media server, and my QNAP NAS appliance (~58TB storage). So no, definitely not "too much" speed for home use. Is there even such a thing?Quote from: tkamiya on April 23, 2023, 09:28:16 pmThen there's definitely something wrong with your setup. I've measured transfer between my desktop and NAS at ~9Gbps raw throughput, and that's strictly over twisted pair CAT6A. No fiber involved. Now not every application can max that bandwidth so YMMV, but for raw data transfer there should be no reason why you can't do much better than 3Gbps unless there's some crappy cable over extremely long and noisy distances.
