ClearPath FEC
overhead
The overhead caused by sending FEC
(forward error correction) packets.
ClearPath repair
frames
The number of repair frames
sent/received.
Control Statistics
Control statistics provide information about the control channels that are established in order that the endpoints can
exchange information about the voice and video streams (Real Time Control Protocol (RTCP) packets). Refer to the
table below for additional information.
Field Field Description Usage Tips
Audio
RTCP
receive
address
The IP address and port to which
RTCP (Real Time Control
Protocol) packets are being
received for the audio and video
streams
Receiver
reports
A count of the number of
"receiver report" type RTCP
packets seen by the MCU.
A single RTCP packet may contain more than one report of more
than one type. These are generally sent by any device receiving
RTP (Real Time Protocol) media from the network and are used
for auditing bandwidth, errors, and so on by the MCU.
Packet
loss
reported
Media packet loss reported by
receiver reports sent to the MCU
by the far end.
ClearPath
FEC
recovered
The number of packets reported
by receiver reports as recovered
by the endpoint through the use of
FEC (forward error correction).
Sender
reports
A count of the number of "sender
report" type RTCP packets
received by the MCU.
These are typically sent by any device that is sending RTP media.
Other A count of the number of reports
seen by the MCU that are neither
sender nor receiver reports.
RTCP
transmit
address
The IP address and port to which
the MCU is sending RTCP packets
about this stream.
Packets
sent
The number of packets sent.
Video (primary channel and content shown separately)
RTCP
receive
address
The IP address and port to which
RTCP (Real Time Control
Protocol) packets are being sent
for the audio and video streams.
