Quality - Max
Jitter
Once for each pair
of sites being
reported.
The maximum jitter is the worst jitter
encountered on any media stream between the
sites given in milliseconds. This data is
retrieved from the A MaxJitter and B MaxJitter
fields in the MediaStream table. The jitter
buffer should be larger than this value for
proper operation.
Note: The 'max jitter' value in this report is
only recorded up to the maximum jitter buffer
value configured in Director.
Quality - % Packet
Loss
Once for each pair
of sites being
reported.
This is the number of packets that were
expected to arrive but did not arrive at the
destination. Lost packets were mostly likely
dropped on their way through the network.
Quality - Blocked
Calls
Once for each pair
of sites being
reported.
The number of media that were not routed
across the WAN due to insufficient WAN
bandwidth (admission control reached). This
could indicate that more WAN bandwidth is
required.
This is a count of the number of records in the
MediaStream table between the two sites with
FailureCode = 1 (Admission Control Inhibited
Call).
Traffic Volume -
Tot al
Once for each pair
of sites being
reported.
The number of media streams used between
the two sites as recorded in the MediaStream
table.
Traffic Volume -
Duration
Once for each pair
of sites being
reported.
The duration of all the media streams used
between the two sites. The value is the sum of
duration for all records between the two sites
in the MediaStream table.
Traffic Volume -
Avg Duration
Once for each pair
of sites being
reported.
The average duration of all the media streams
used between the two sites. The average is
total duration of the media streams between
the two sites divided by the number of such
media streams.
