Round Trip Time (RTT) - Round Trip Delay (RTD)

Round Trip Time is the time required for the packet to move from source to destination plus the time of moving the response or acknowledgment. This represents how much time a packet will take to move from the source to the destination and back again.

 RTT is also called Round Trip Delay (RTD) and measured in milliseconds(ms). The user can determine the RTT by using the ping command, as shown below

The ping command shows that the minimum RTT is 1 ms, means that the minimum time required for the packet to travel from this user to the destination network device 192.168.1.1 and back again is 1 ms, and the maximum time required for the packet to travel from this user to the destination network device 192.168.1.1 and back again is 3 ms.

So, the average time required for the packet to travel from this user to the destination network device 192.168.1.1 and back again is 2 ms.
