I need some feedback, comments or whatever.... The average house has a 230V feed good for 60amps. It suits most people apart from a few with fixations on large swimming pools, huge sauna, large lathes, and growing pot. (power bills or substation loads were a dead give away) They got 3 phase power or jail. Almost no one ever got 11kV. (I say no one because we did supply several businesses that way) What is the data equivalent to a 230v 60 amp supply ? 10 100 100 Mbps ? 10mbps - too slow generally 1/2 duplex gets ugly as it gets max'd out. 100mbps - cheap, reliable, goes well. MPEG-2 fits in nicely (6mbps) so a house would get say 10 simultaneous TV channels eaisly (newer codecs like MPEG4/DiVX work for the same quality at 1.5mbps, so as faster cpus come into wider use bandwidth gets conserved). 100mbps allows very easy power+data on one tail. Routing/firewall is easy and cheap at wire speed. 1000mbps - becoming cheap. also reliable. might mean power on separate cable or less power available. Firewalls/routers expensive unless you home brew..... So - what is it ? TIA - rich
"The technology exists to give every home 10mbits per second for $10 per month!" That comment was made to me by Geoff Huston a couple of years ago. I personally like that price point but if we could get wireless nodes running that mean people could use wifi phones rather than mobiles around most of their cities/town then I think the price point could be up to $30. Based on that answer the question then becomes "what can we build for $10 per month?" Has the cost of technology come down enough in the past 2 years to prove to Geoff that we can deliver 100mbits for $10 per month - I suspect it has for local access. His comment was based on CIR of 10mbits for all types of traffic (I made a point of asking). On Sun, 28 Dec 2003 00:30:03 +1300, Richard Naylor wrote

Agreed.
I agree that this is probably what we want to aim for. I think with improved compression and faster hardware we won't even need 1.5mbits for video by 2007.
The message I've been getting over the weekend from you guys is that we have to be thinking 1gbit for backbones that run around suburbs. So this means 100/1000 switches with some fibre linking things up - not so different from what Telstra have been installing around the place? So what you're saying is... run 1,000mbits down the road then drop 100mbits into each home.
So - what is it ?
