Generally speaking, we can calculate the packet delivery time using this formula, Wikipedia:
Latency = Transmission delay + Propagation delay + queuing delay + processing delay
My question is: Is it acceptable to use the value of RTT to be the estimated latency? In fact, the simulation environment I use provides the calculation of RTT so I wonder if it is close enough to use this value to be the estimated latency of a path from source and destination.
Kindly, I'd like to refine this reasoning if it is not correct.
