Internet Speed at Google =)

You will never need to communicate anything faster than at the speed of light (faster in the sense of delay, not rate). Unless of course, you want to remote control something.
Blah, yes, I started with an idea, and it turned itself against me.
Light speed is a real detriment to intergalactic network gaming. Something about physics must be done. Quantum entanglement?

J4D

A faster but more expensive method that i just thought about might be by using an equivalent of a parallel bus using fiber optics !
Instead of using one line to transfer data on. we use multiple cables.
imagine a 32bit parallel communication medium. Thats 32 separate fiber optic cables catering only one connection .
Now lets reduce that to a 4bit parallel system to ease explanation (4 cables) .
on a normal one cable setup the data will travel one bit after the other to deliver a number* on the other end
on 4 cable parallel setup each bit will travel on its own separate pipe !
thats:
bit0=0
bit1=1
bit2=1
bit3=1
all the bits will arrive at the same time rather than arriving one after the other on a one cable setup !
DAMN IM SMART :D now im off to do a working model :P

J4D wroteall the bits will arrive at the same time rather than arriving one after the other

That's a very cool idea, but I have a "however".

HOWEVER: Can you be sure that all 4 bits will arrive at the same time? Let's say that the transmitting equipment is imperfect (the cables can also be imperfect, but let's assume they're ideal). There's no way to guarantee that the transmitters will all send the bits at the exact same time. You need to have some kind of synchronization at the receiving end, which means waiting for bits to sync up, which is a delay!

There's no justice in the world, I tell you!

When using fiber optics, you don't need to expand on the space dimension since the frequency bandwidth allows for a huge amount of information to be transferred. You'll just waste precious fiber cable and will not save on the optimal latency.
Quantum entanglement allows faster than light transfer of information by separating entangled photons into different parts of the universe. Think of it as an IT-Worm-hole.

Actually light is not fast enough...

The direct distance between Madrid and Sidney is about 18,000 km, so if we connected the two cities with an optic fiber cable, a direct straight link.

Latencey= distance/speed of light * 2 = 18,000/300,000 * 2 = 0.12 sec = 120 ms

In reality, the distance is much larger, because laser pulses are not traveling straitly along the optic fiber, they are reflecting inside the tube...
Also the optic fiber cable will never be connected directly between Sidney and Madrid without huge turns, because there are many high mountains and very deep oceans in the way... any optical cable will easily cut more than double the 18,000 km arc, to overcome natural and human made obstacles...

So practically, the latency will always be above 300 ms regardless of the advancement in the hardwares on both terminals...

Now that is small issue, in future when humans live in the outer space (Moon, Mars...), the latency will be in minutes...

To sum it up, light is not that fast, and humanity should invent a faster than light communication technologies (Superluminal)...

J4D

Thats not a problem at all :) since just like in normal fiber optics communication you need to wait for the bit to arrive to enter it into the system. here their will be a predetermined delay just like normal fiber optics to open the gates and read the parallel pipes :) same thing really, but 4 times faster. if not 4 times its 3.9999 times faster :P (if using a 4-bit parallel bus)

arithma

Not 4, not 3.999 not 2, not 1.999.
It's close to 1 if not less. Costs more.
Frequency modulation means the bits arrive together, on different frequency channels, same as when your TV antenna receives all the channels together on different frequencies. You're the Communication expert fuck it.

Wavelength division multiplexing

It have been used for more than two decades!

J4D

Im still talking about my method, not your multi frequency blabbering.....

J4D

Okay, apparently my brain functions correctly :)

rami

Google bought huge chunks of networks and IPs. There were rumors about Google entering the ISP market, but in never materialized. Now I see where those purchases went :-)

They did:

Your method is the same as wavelength division multiplexing... it only costs much more...

arithma

Sometimes, you make me want to shove my foot so deep inside your ass that I worry about my knees. Your idea sucks, we'll leave it at there. Commence your mental m**********.

Samer99

Whether it was a multi-fibers or a multi-wavelengths technology (actually, both methods are used in the mean time, because submarine communications cables nowadays contains many fibers, and each fiber carry many wavelengths...), but that will not solve the latency problem, it will only solve the bandwidth problem.

J4D

My idea sucked real bad after we discovered that it is actually used :P

arithma

Pulls foot real slow so that Jad doesn't get hurt. Sorry. Your idea is nice. For submarines.
I believe the bottleneck still though, is in the de-multiplexing of wavelength modulated signals of too much congested backbones like submarine cables which is why they'd need to distribute the load.

There is a theoretical particle which travels beyond the speed of light it is called Tachyon, in Quantum Mechanics. I was just emphasizing the fact that NASA should be strong in that field.

As with the calculations the guys did is really easy for a student who passed by the Scientific Grade 11.

Agreed =)
Just a small FYI here, keep in mind guys that we, and by we i mean worlwide population, is fairly behind when it comes to technology.
For example : In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and technologies for interlinking packet networks of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks

The internet wasn't made public untill 1990's...

so yea, my guess is the pentagon and nasa's technologies are being kept secret for a reason... why ?
simple.
Because it will make our technology look like garbage.
So my guess is the do have something better than a " fiber optics cable " to interlink their networks.
These technologies will be made public when they come up with something better than the ones they actually have now .
It's a circle of life =)

You know, I've always wondered. (And yes i can search, but I'm too lazy)

1- Bar latency, what's the transfer rate of a fiber optics cable?
2- Assuming you have two machines and you want to interlink those through fiber optic cables, what are the devices you need? Special network cards? Special routers?
3- Are all those devices available in lebanon?
4- Price estimate?

1 - Fibre optic cables are definitely cool. They provide a transmission length of 10km or more for single mode fibre, or 2km or more for multi mode fibre. Fibre optic cables can also provide maximum data transfer rates of more than 100Gbps

2 - a-Find a fiber optic Internet service provider in your area
b-Register with the company of your choice and wait for the installer to come. The fiber optics installer will connect the fiber optics from the distribution box in your neighborhood to your home.
c-Install the Optical Network Terminal (ONT) in your house. The installer will also provide this service. The ONT is used to connect the fiber optic cable to your home through a 100BaseT wire. The ONT usually will replace all telephone lines in the home.
d-Install (or have installed) an RJ-45 jack into your house. This jack allow the 100BaseT cable to connect to your router, which is how the fiber optic power provides your Internet.
e-Have your telephone numbers switched over to the fiber optic cable. Test the connectivity of the cable by hooking up your computer and make sure it works correctly.

3- Downtown, sodetel and such

4- a LOT =P

Cheers =)
