A new technology in development called "Fast TCP" promises to dramatically increase download speeds using the same infrastructure.

TCP is the protocol used by the vast majority of Internet and private network transmissions. Used since the 1970s, this protocol has alot of safegaurds in place to protect the integrity of the data, however, they are no the most efficient.

Data is broken up into packets, which when sent to the recieving computer, must recieve a successful reply signal before the next packet is sent. If there is no reply, the packet is sent again, at half the speed, until it finally suceeds. Unfortunately because of this, minor glitches can result is extremely sluggish speeds.

Fast TCP proposes to fix this problem by continuously monitoring these replies to reveal delays and to predict the fastest possible data rate the connection can handle without data loss.

Research trials have shown average speeds of 925 megabits per second, as opposed to 266 megabits per second using regular TCP on the same route. Also in a trial that grouped 10 Fast TCP systems together, they were able to acheive top speeds of over 8.6 gigabits per second!

Interesting! It's time they "upgrade" TCP/IP. I never seen 100mbps on my network, and it's exactly because of those glitches.

I am awaiting this as well as the "upgrade" to fiber!

I can sell you a Cisco OC12 router for $75 000 if you want...

Thing about fiber is that it's expensive (the connectors themselves are $5 USD a pop, and I won't even get into some of the equipment like fusion splicers) and a single fiber will only give you 1.544mbs, so it's not exactly faster than copper. The real draw of fiber is the distances it can travel without a repeater and the fact that it is immune to electromagnetic and radio frequency interference.
