    Through the use of SONET / OC-192.. you can get speeds of up to 9953.28Mbps... *drools*

    lol ya....but personally past a certain point one person wouldn't notice such a thing. Of course this is designed for huge corporations and world wide webservers and stuff like I'm jsut saying at that speed that you just mentioned you could download a 1.2gig file in about 1 second.

    You've got to remember that bandwith is all theoretical, really... though I'm sure we'll be seeing 1.2GB files being transferred in milliseconds one day :).

    YA woohoo But that one day probably won't be to impressive. As back in the day we had 12baud modems but what were we download?G TEXT! Now we have people download MP3's and software and huge graphic intensified webpages. Or we could surevive with small hard drives "back in the day" cause there was nothing to take up alot of space. Now we have multi gig worth of games and music on our PC's. So its all connected. That 1.2GIG file may end up being nothing more then half a meg to us now in the future. ;)

    I2 is also around. It may just be a certain OC but it's all virtual reality, they have surgeons do operations through it.

    Anyway eventually people will be calling OC-1 very slow :rolleyes2 It will be the new 56k...
    New Sig soon, old one was way outdated.

    Researchers in Europe have succeeded in setting a new world record for internet speeds, sending data at a rate of 483 megabits per second - nearly 500 times faster than even a well equipped home or business user can normally expect to achieve. The record was set over an ordinary internet connection running for 2,518km between Slovenia and Spain, using the new Ipv6 protocol. While the technique has been available for some years, most parts of the internet do not use the protocol because to do so would require extensive upgrading of hardware and software. In setting the record, 483mb of data were transferred in 11.73 seconds, equating to a speed of 1215 terabits per second, from Ljubljana in Slovenia to Madrid, via Milan, Geneva and Vienna.
    OK, first off, IPv6 isnt a protocal or ANYTHING to do with high speed networking. IPv4 was the common IP address standard such as IPv6 is just a new numbering standard to increaser the limited number of IP addresses we have left. (You would think would allow 255^4 addresses, but with subnetting, loopback, broadcast, and mulitcast numbering its far less than that)
    Second, shouldn't that 483Mb of data be transfered in exactly 8 sec to have 483mbps of bandwidth?
    Third, calculate it. Terabits or terabytes dont even come into play.

    As far as T1's, T3's, and T4's they all exist as do T12's and everything in between. Its just the relative cost of tying up that many POTS lines into one user(or one network, like a corporation)
    T lines are digital and use a certain nuimber of phone lines to transmit to the CSU/DSU which sends it to a router, which sends it to your PC via ethernet at speeds up to a gigabit. (remember guys if your NIC or cable cant handle it, **** it.)
    T1 is 1.544mbps, T2 is twice that, T3 is three times that (6.5ish mbps) all the way up to 12, which would be 1.544 * 12. You figure it out. I've never seen any standard for anything past that - its too costly. Fibre is much cheaper to run that 8 tele lines for a T1 (24 for T3, 96 for a T12) because fibre can handle more than any signaling method we've come up with for it, including ATM OC-3072. And the only reason they have ATM OC's (ATM is the signaling type, OC is the fibre) is for a connection between routers that can handle it. Routers, those things that handle every last packet sent by every last user on the internet, can handle those speeds. You gotta remember thats everyones traffic on the internet those things deal with, every last packet.

    and i agree with respawn, its all relative, someday we could laugh at an ATM OC3 because it takes 10 seconds to beam you up to your friends house, whereas ATM OC-3072 takes only half a second...

    who knows?
