Voice Jitter (sec)
If Tc(i) is the difference between the times when packets i and i + 1 were created at the source node
and Tp(i) is the difference between the times when packets i and i + 1 were played back at the
destination node,then Jitter = Tp(i) – Tc(i).
MOS Value Recorded Mean Opinion Score (MOS) of the voice trafc.
Packet Delay Variation End-to-end delay variance experienced by the voice packets from the time they are created until they
are received.
