8.2.17 Measure Round Trip Time
This function measures the round trip time between the local device and the remote device.
"Round trip time" is the time taken to make a communication between two devices.
Only one remote device can be measured at a time.
The procedure to measure the REC round trip time is as follows:
Procedure
1 Select the remote device to measure the REC round trip time, and click [Get Round Trip Time]
in [Action].
• Round trip time can be measured only when the connection type is "Remote". Round trip time cannot be
measured when the connection type is "Direct".
• Set the REC session status to "Suspend" between devices before measuring.
• Make sure that the physical path is correctly configured between devices before measuring. When a copy
path has an error, the round trip time cannot be measured correctly.
• If the path between devices is changed, measure the round trip time again.
• Round trip time measurement requires a maximum of 160 seconds.
A remote device with "Direct" as the connection type cannot be selected.
