I'm not going to pretend that 1Gig isn't enough for most people. But I refuse to believe it's the networks equivalent of a 10A power (20A depending on where you live in the world) AC residential phase distribution circuit.
This isn't a question about what people need, it's more about what the market can deliver. 10GPON (GPON-X) and others now make it a viable service that can and is being deployed in residential and commercial access networks. 3 years ago delivering an access network Capable of anything beyond 2.5Gbit was pretty much a Business case non-starter. The problem is now that Retail Servicer Provider X can deliver a post Gigabit service... what is capable of taking it off the ONU/CMNT point in the home? As usual it's a follow the money question, once RSP's can deliver Gbit+ they will need an ecosystem in the home to feed into it, and right now there isn't a good technology platform that supports it; 10GBase-X/10GBaseT is a non-starter due to the variability in home wiring - arguably the 7 year leap from 100-1000mbit was easy It's mean a gap of 12 years and counting for the same.. it's not just the NIC's and CPU's in the gateways it's the connector and in-home wiring problems as well. Blatant Plug - request : I'm interested to hear opinions on this as I have a talk on this very topic 'The long and Winding Road to 10Gbit+ in the home' https://linux.conf.au/ at Linuxconf in January. In particular if you have any home network gore/horror stories and photos you would be happy for me to include in my talk, please include. -Joel on the tweeters: @aenertia On 4 December 2017 at 22:13, Mikael Abrahamsson <swm...@swm.pp.se> wrote: > On Sun, 3 Dec 2017, Dave Taht wrote: > >> What Jesper's been working on for ages has been to try and get linux's PPS >> up for small packets, which last I heard was hovering at about 4Gbits. > > > You might want to look into what the VPP (https://fd.io/) peeps are doing. > They can at least forward packets at pretty impressive rates. 200Mpps zero > frame loss with 2M FIB, limited to NIC and PCIe, not CPU (on many-core > machine). > >> I have never thought there was much of a market for gbit to or from the >> home. 40Mbits is enough for nearly everybody until > 4k video with >> smellovision and tactile feedback become a standard. > > > I'd say the sweet spot right now is in the 100-250 megabit/s range, > considering "cost of production" and "what do people need/use".
