Theoretically estimate network round trip time

How can the network round trip ping time between 2 countries, say US and China be theoretically investigated? (without using tools like ping and traceroute ofcourse)

If you are doing this all via the internet… then it isn’t possible to estimate the delay as you have no idea where or how the traffic is traversed.

However, if you are looking at leasing a private line… then yes, it is possible. Large companies do this all the time.

Example; In a straight line, China is 10,000 Km from LA.

Now, given that light travels through fiber at around 200,000 km/s, it would take 50 milliseconds to travel one way to China from LA … 100ms round trip.

So 100ms is theoretically the fasted you could get between LA and China, if a direct path was used.

As you can see from http://www.cablemap.info/, there isn’t any direct path. However, if you knew what route your traffic was taking, you could calculate a near enough estimate.
