In theory, doesn't electricity travel at the speed of light? 186,000 feet
per second, I think.
I once read theory that electricity flows through copper more efficiently
than light flows through fiber, so the electrical bits would arrive first in
a race.
I have both interfaces here in the lab...
The speed the bits travel should be negligible in comparison with the time
it takes the intermediate(routers, switch,...) and end nodes to
receive/process the signal. So if you're curious for computational purposes
it wouldn;t matter. Electricty in a vacuum travels at light speed. I'm not
sure the
There are several factors:
1) Clock rate of the line
2) Buffering delay by any intermediary devices such as ATM/FR switches
3) Speed of light
If we take a simple case and say that there are no layer 2 devices in the
path and only digital cross-connects. I have read (somewhere) that the
speed of

Miles per seconds! ;-) As Wes said, "The rough calculation for the
propagation
of an electromagnetic signal in wire is 66% of the speed of light in a
vacuum. O
Great answer!

now if he recited that from memory, we should all just throw in the
towel hehe :) I certainly suck at math anyway...reciting some crazy
formula to calculate latency would send me over the edge!

Great answer!

At 02:01 PM 4/11/02,
I'm going to chip in both with some simplifying rules and some
additional information. I suggest you also read RFCs 2679 and 2544.
I will have the first white paper of a performance series available
free on Certzone on May 1.

almost as much and that is if it is fiber all the way. When you start
looking at voice budgets you have to take line delay into account.
