Round-trip delay - Wikipedia
In telecommunications, the 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 an acknowledgement of that signal to be received. This time delay includes the propagation times for the paths between the two communication endpoints.
