What is RTT

RTT — round-trip time

How to check RTT time？

[SupreetK]

RTT is the cumulative time taken to send a signal and receive an acknowledgment for the same. A simple ping test will give you the RTT between the source and the target. Is there anything in specific you want to know about RTT?

Which value is RRT?

[peetz]

When using the ping utility on Windows look at the last two lines of the ping output to get the RTT summary. It says something like

Approximate round trip times in milli-seconds:

    Minimum = 1ms, Maximum = 3ms, Average = 2ms

For a single ping the RTT is just shown as "time". In your example it's always "time<1ms", so the RTT is less than 1 millisecond.

When using the ping utility on Linux you usually get more detailed/accurate values.

I see. Thanks !

RTT is typically measured using a ping to calculates the time taken to reach a user device.

Actual RTT may be higher than that measured by the ping due to server throttling and network congestion.

Per example in your screenshot the RTT is less than 1 ms. (time<1ms)

Hello,

It is a latency time between source and remote devices.

From VMware it is a requirements from long distance vMotion as per the following: VMware Knowledge Base
