This is calculated continuously in milliseconds as each data packet is received
and totalled.
This is calculated continuously in milliseconds as each data packet is received
and the total is squared.
Fraction Lost: The fraction of RTP data packets lost since the previous SR or
RR packet was sent. This fraction is defined to be the number of packets lost
divided by the number of packets expected. This will be calculated on every
RTCP SR packet. Sum of the fraction lost is calculated with all the RTCP pack-
ets.
Fraction lost is squared with every RTCP SR or RR packet. Sum of all this will
give the Sum of Franc Loss Squared.
One Way Delay will be calculated in milliseconds on every RTCP SR or RR
packet. This value is (systime - lsr - dslr) / 2
lsr means last SR timestamp
dslr means delay since last SR.
The sum of all the one way delays calculated in milliseconds on every RTCP
packet is displayed as Sum of One Way Delay.
One Way Delay is squared with every RTCP SR or RR packet. Sum of all this
will give the Sum of One Way Delay Squared.
