Chapter 5 - Monitoring Conferences
5-58
The Connection Info1 window displays the information sent from the IP
card to the MCU control unit. This information is refreshed every two
seconds. The information is derived from:
—RTP
—RTCP reports
—Media channels
The RTP information is created by the RTP processor of the IP card, such
as packet loss, overflow, packet fragmentation, jitter buffer parameters,
and delays. The RTP statistics are displayed in two views, Accumulated
and Interval:
—In the Accumulated view, the system displays statistics that it
gathered since the session start (since the participant connected to
the conference).
—In the Interval view, the system displays the statistics for the last
five minutes, and it is updated continuously.
The RTCP information is taken from the RTCP reports sent and received
by the MCU (IP card) to/from the endpoints. This information is
refreshed every 5 seconds.
An exclamation point appears in the Faulty column in the Channel Status
box when a faulty condition is detected for a channel, for example, the
packet loss has exceeded a threshold defined in the system. The
parameters thresholds are defined in the system.cfg file and are based on
standard network behavior. An exclamation point indicates that further
investigation may be required, using the additional parameters in the
Advanced pane. This is a real-time indication; when the faulty condition
is resolved the exclamation point disappears.
The following information is displayed in the Channel Status table:
