In NZ, Sharing Ethernet With A Whole CIty

Actually, the reason that Chicago is called the Windy City is that during the battel for who was going to host the 1900(?) world's fair, Chicago made all kinds of promises for the site that it was goign to be hosted on. In response some mayor said "Don't believe those Windy politicians from Chicago!", windy politicians==Windy city, the name stuck.
In Gävle, weden there is a citywide LAN already. A nifty NAT with Gigabitbackbone and 100Mbps to each houshold. Some households even got fiber installed all the way.
Västerås Sweden has built there redundant Gigabit backbone. They are working on connecting the companies and households.
The diffrent between the two city-LANs is that Gävle includes a Internet-connection as standard. Västerås only sells the fiber within the city. I think Gävle made the best, people don't want to buy cabel and Internet. They just want to surf.
Isn't the term for the type of network they're creating a "MAN", or Metropolitan Area Network? There was a big push for these several years ago. Indeed, and I'm not diminishing the accomplishment involved in getting this done in NZ, I know of several towns in Southern Ontario that outfitted their entire town with fiber optics for control systems (because of attenuation problems/distance they couldn't use copper), and they offered businesses internet access at least 3 years ago: I think this is a pretty common thing for `hydro' (which is what we call combo electricity/water companies here) to do. Now they don't sign everyone up for free, nor do I think they should: Why should the city foot a giant bill because a guy is hosting a mega porn server when the next business is using it to check hotmail once a day?
Just to be a pedant, Wellington doesn't have trams, it has trolley buses. These are electric buses which get their power from overhead wires, but are steered just like a bus (of course they can't stray too far from the wires!). There's also a cable car as well in Wellington, but no trams.
Onto the point I was going to make...I remember a few years ago they were talking about taking out all the trolley buses because the buses were in need of replacement and it would be too expensive to replace them - normal buses were the desired replacement. Bit of a bummer for CityLink if they did tear down all the wires.
I hope they keep the buses, because it would seem that lots of other cities ripped up this kind of network in the 70s and 80s only to start regretting it later.
Straight from RFC 2962:
There are currently three versions of SNMP. SNMP version 1 (SNMPv1) protocol is defined in STD 15, RFC 1157. The SNMP version 2c (SNMPv2c) protocol is defined in RFC 1901, RFC 1905 and RFC 1906. Finally, the SNMP version 3 (SNMPv3) protocol is defined in RFC 1905, 1906, RFC 2572 and RFC 2574. See RFC 2570 for a more detailed overview over the SNMP standards.
Now its back to the old days, SBC/Ameritech is the monopoly again, and things are going down hill, all over again, due to corporate greed, and monopolization.

Reading articles like this just make me so damn depressed. In South Africa, we have a major problem with our Telecommunications company. They're a monopoly who controls absolutely every single aspect of communications in this country. We are being held back by huge laws which prohibit the use of any other internet connection system or device if it is not using Telkom's infrastructure. The worst thing is that the best connection we can get to the internet in this country is ISDN if you can't fork out the megabucks for a Leased Line solution. What absolutely grates me more is the mere fact that they close down companies who attempt to run alternative connection systems. Wireless providers start up but get shut down very quickly thanks to the Telkom legislation. Connecting to your neighbour is also illegal if you take a cat5 cable and run it over the wall! By the mere definitions in the legislative clauses Telkom enjoys the right to force you to rent their equipment only. And when you have 3.5 million people connecting to the internet over a duplexed 45meg pipe to the international spectrum, it must measure up to the worst infrastructures for Internet enabled countries in the world. And we're supposed to be the gateway to Africa?
I hope that someday things will change and we can also have a 1000 mbps LAN connecting our cities.
Since they consider themselves a LAN, I was wondering what addressing scheme they're using.
Are they using "real" IP addresses? If so, what class?
Or are they using public address (10.0.0.0) with a NAT box to access the internet?
Just wondering.

I enjoyed two articles on ExtremeTech: High-Performance Buses and Interconnects by Leon Erlanger (dated November 8, 2001) and The Interconnect Conundrum by Nick Stam (dated January 28, 2002).
"So he ran a fiber optic cable between the plants, allowing them to compensate by sharing power when one was hit by a shortage."
This is one of many strange statements in the article. I'm not the 1st one to point this out, but transmitting POWER over OPTICAL fibre is not really possible (at least outside NZ).
Creative reading of my earlier post.
However, taking you at face value, I would remind you that it was only after 1992, when the US Government stopped trying to control the routing tables, that what YOU know as "the internet" actually took off.
You might be surprised to know there was a time when it was illegal to use "the internet" for commercial purposes.
Many thousands of private individuals who worked on, contributed to, and built what you know as "the internet" didn't work for any government.
I recomend you read a book next time before posting.
