Time to receive an ICMP packet?

Question

Computer networks

A dedicated communication line has been stretched - 9,000 km. What is the minimum allowed time for an ICMP packet sent from the first server to reach the second server?

Answer 1

Is there a single continuous line from point A to point B of this length? Would you like to joke? The length of Russia from west to east is 8000 km, if only che. Without intermediate nodes, such a "line" does not exist and cannot exist.

Answer 2

~0.03 ms

Answer 3

Depending on how long it is, a lot depends on the reflection of the signal, it can be 2 milliseconds or maybe 999 kinks, turns, etc. The noise of the optical amplifier, etc. besides, the optics become cloudy over time, so after 10-15 years,
if we take ideal conditions, that is, the speed of light, then this less than 1 millisecond but ideal conditions do not exist

Answer 4

There are no "leased lines" of this length - voltage drops, etc. say hello. This means that the question is meaningless, since it is necessary to consider the influence of intermediate nodes, the delays of which cannot be taken and predicted globally.

Answer 5

Although the answer has already been given, but I'm a little bit boring.
In wired networks, it is generally accepted that the speed of signal propagation is equal to the speed of light. No difference optics or copper. Hence the simple math. Length / speed of light. The desired answer will be.
