Media Loss Rate (MDI): Ratio of lost packets to received packets in one
multicast stream (only for RTP protocol after FEC) (recommended value <
0.005 pkt/s).
Resources Busy: Resources busy shows the "%" of equipment resources
used for handling current IP traffic. Arriving at 100%, means the receiver
can't handle all packets related to data and IP protocols other than
Multicast stream. In that situation, data loss may happen.
6
Measurement on the multicast reception: received packets, RTP missing
packets, FEC fixed packets, buffer usage, stable reception and TS bitrate (if
TS input has many variations in packet reception a stable packet rate cannot
be established).
7
Measurements over all traffic data in the network: network bitrate, IP packets
with errors and IPER (IP Packet Error Ratio; ratio of Ethernet packets with
errors to Ethernet packets received).
8
Softkey menus (see "Settings" section for more details).

Measurements on the data network: Delay Factor, Media Loss Rate and
Resources busy (see previous section for more details).
5
Measurement on the multicast reception: received packets, RTP missing
packets, FEC fixed packets, buffer usage, stable reception and TS bitrate (if
TS input has many variations in packet reception a stable packet rate cannot
be established).
