watch ur language! lol, newayz, yes theres internet 1000x faster than cable, its called OC-24. how much will you "fast tcp" be?

there is one problem there. Most internet sites can not even upload as fast as I can download now. so a fast conectoin could not speed me up any faster.

OC-24 is actually
more than 1000 times faster than cable. OC-24 runs at 1244.16 Mbps.

I agree with Timeless... You can make things as fast as you want, but I'm not buying into it unless I'm going to host my own site...

Cable has a maximum bandwidth of 10 mbps (1.25 megabytes per second). My fastest download on cable has only been about 950 kilobytes per second though. However, OC-24 is not the fastest.

yea i know, i was just exaturating. i didnt have time to think of numbers that would exist and be exactly 1kx. (and i accidentially said 1k instead of 6k) ive heard theres such thing as OC-1024, but isnt there an infinate amount of bandwidth as long as you add more fiber cables? i dunno much bout optic carrier technology..

One of my teachers teaches about optical technology. He gave this lecture a while ago
Physics Colloquium
Russ Herman, Mathematics & Statistics, will speak in DeLoach Hall 212 at 2:00 p.m., Friday, March 21. The title of his talk is ``Soliton Propagation in Optical Fibers." Refreshments will be served at 1:45 p.m.
Abstract
Solitons have been studied in many fields of science; however, the most promising applications of soliton theory are in the field of optical communications. In such systems information is encoded into light pulses and transmitted through optical fibers over large distances. Optical communication systems are no longer the pipedreams of the future. Commercial systems have been in operation since 1977. Last year Bell Labs scientists transmitted 64 channels of data at 40 gigabits per second per channel over 4000 kilometers (2500 miles). The development of optical fibers, which are the basis of such systems, has lead to a revolution in communications technology. In this talk we will review the history and physics of optical communications with an emphasis on the theory of soliton propagation in optical fibers.
Note this: "64 channels of data at 40 gigabits per second per channel" is equivalent to 2.56 terrabits per second (Tbps)

holy crap thats a butload of bandwidth! i think thats OC-768 but im not sure.

dunno if this is accurate but whatever. newayz, i have a ?. if u have speeds of say, OC-3 (155 Mbps), is that all on one fiber optic cable or through a series of cables? is a channel a cable? (im a n00b when it comes 2 optics)

for comparison, in terms of mbps, how fast is the PCI interface?
usb?
usb2?
firewire?

all i know is this
PCI is 33 MHz (dunno Mbps)
USB 1.1 is 12 Mbps
USB 2.0 is (i think 800 Mbps)
and i think Firewire is like 400 Mbps

It has been said that it is highly probable that internet download speeds may someday exceed the write speeds of the harddrives. Once that happens, then the bottleneck become the hardware.

thats already true w/ optics, just not affordable. hard drvies cant write 2 GB/s. if this becomes affordable to the average working person, then this is where home networking comes in to share that bandwidth. or until massive solid state storage devices appear in an affordable state

USB 2.0 is around 384Mbps, I think. The original FireWire standard (IEEE 1394) was 400Mbsp; IEEE 1394b ("FireWire 800") is 800Mbps.

both of us were wrong bout USB 2.0
The USB 2.0 specification has a design data rate of 480 mega bits per second

edit:
i find this hard 2 believe:
It enables the extension of the standard first to 800 Megabits/second and 1.6 Gigabits/second, then on to 3.2 gigabits/second, using plastic optical fiber.

www.ieee.org is a confusing site, and i think i dont fully understand how firewire can be 3.2 Gbps
