RTLT meaning in Academic & Science ?

Answer: What is Round Trip Light Time mean?

In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. In the context of computer networks, the signal is typically a data packet. RTT is also known as ping time, and can be determined with the ping command.

End-to-end delay is the length of time it takes for a signal to travel in one direction and is often approximated as half the RTT.
