    "Hang on we supply electricity via a distributed network rather than Point 2 Point, why can't we do the same with the internet... hang on its cheaper as well"

    Real issue here though is that the City backed up the smart guy rather than getting CorporationX to do it, had then gone for the latter route they would be right where the rest of us are with our T1s to the Telco backbones.

    I predict this won't happen in big cities because they have too much money to be sensible.

    As another cost-cutting measure, Citylink uses a generic computer running Debian Linux and SMTP management software, as well as a number of other open-source tools: NetSaint Network Monitor, NocMonitor, MRTG, and Cricket . And the company builds its own routers, rather than dropping the money on hardware. Naylor says a comparable Cisco router would cost him $25,000 NZ or roughly $11,500 U.S.; Citylink builds its own routers for $2,500.

  11. Hello! Remember IBM? by fm6 · · Score: 3, Insightful
    If Microsoft hadn't decided to go into the OS commodity business, we wouldn't today have a commodity hardware business.
    I'm afraid you have your history muddled. The "generic" computer existed before MS got into the OS business, and is the reason why they did so. (The more usual term is "commodity computer", which more accurately describes its origins and role.) Of course it wasn't called "generic" or "commodity" at that time. It was called "The IBM Personal Computer".

    Those three letters were magic. At the time, computing was dominated by big expensive mainframes, and IBM had no less than 90% of that market. They were, in other words, the Microsoft of the 60s and 70s. To survive, your product had to be compatible with the IBM PC at every level. IBM itself took a long time to see this, and came out with non-compatible systems like the PCjr and the PS/2. Which is why the "IBM-compatible" market isn't dominated by IBM.

    The one way Microsoft helped out was by providing a crappy operating system -- actually more like a glorified program loader. Since MS-DOS did such a lousy job of insulating applications from the hardware, apps had to incorporate a lot of hardware-specific functionality. Which forced IBM's competitors to emulate the PC at a very low level.

    Everybody engineering to the same specs created opportunities for commodity manufacturers -- and created the "generic" computer. Which still has basic design features that totally suck -- like that big heat-generating internal power supply.

    Perhaps if Microsoft had hired somebody who knew Jack Shit about re-entrant code or how to write a scheduler, we'd all still be using proprietary architectures. Kind of ironic.

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?

    Recently, we moved premises and because Citylink was available in both locations, i have been able to securely bridge my two locations (using Linux-running routers on both ends) transparently over Citylink, which means the users don't even notice that all the servers and outbound router are still down the road.

    LAN traffic averages about 2Mbps across the link, and if we had done this using our link to TelstraSaturn (our ISP) we would have ended up with a bandwith bill of extraordinary proportions.

    The link was set up simply by assigning an unused 192.168.x.x address to both ends of the connection, running VTUN across this link and then bridging the virtual interfaces using Linux's bridge-utils.

    Basically we get a full duplex 100Mb Ethernet cable hanging in our machine room, and we can participate on the BGP peering system available on the network.

    In New Zealand, ISP tarrif charges can be high (at least, this is the dirty rumour going about). For about, er, NZD$350 per month, we can get all-you-can-eat traffic to any of our peers without crossing an ISP. It's free, and fast.

    The slowest access available is 10Mb (Ethernet). So, worst case scenario is that your updates to local servers (like linux.wellington.net.nz, for example) are blazingly fast; 100Mb access to the same server is staggering.

    Naylor's vision was extraordinary, and has enabled Wellington to be a wired city in ways most people can only dream about :) We have cheap access to a high speed MAN, peering with our neighbours, and a really quick and easy way to connect to our ISPs without paying telco frame relay charges etc.

The network has grown and expanded since then, gaining better core kit and so on. It's amazing now, and promises to get better. What cities need to appreciate is that it won't happen overnight; your network needs to grow organically overnight. Pick a good location for installation, get some interested companies, and be willing to take a little bit of a hit in the first year.
