The cumulative sum of all round trip time measurements in seconds since the beginning of the session.

Description

Real number; in seconds

Represents the cumulative sum of all round trip time measurements in seconds since the beginning of the session. The individual round trip time is calculated based on the DLRR report block in the RTCP Sender Report (SR) RFC3611.

This counter will not increment if the roundTripTime can not be calculated
The average round trip time can be computed from totalRoundTripTime by dividing it by roundTripTimeMeasurements.
