Duplicate IP-frames in the network can occur under normal
circumstances and does not necessarily indicate network
problems.
The following sequence will generate an RTP dups of +2:
..., 10, 11, 12, 12, 12, 13, 14, ...
RTP ooo: Accumulated number of times a packet has been found to be out
of order.
Only available for multicasts that carry RTP information.
An out-of-order situation is defined to have occurred when the
current sequence number is lower than the previous one.
The following sequence will generate an RTP ooo of +2 (since
there are two occurrences): ..., 10, 11, 15, 12, 16, 17, 13, 14, 18,
19, ...
RTP lag: The maximum number of packet positions an out-of-order packet
has been moved relative to its correct position. So for example
1,2,3,5,6,7,8,4,9,10 will result in an RTP lag of 4.
The RTP lag is a good measure of how big a packet re-ordering
buffer is needed in the receiving equipment to re-order packets.
Min hole size: Minimum number of consecutive dropped RTP packets. The
sequence 1,2,3,10,11,12,15 gives a min hole size of 2.
Max hole
size:
Maximum number of consecutive dropped RTP packets. The
sequence 1,2,3,10,11,12,15 gives a max hole size of 6.
Min hole sep: Minimum number of RTP packets separating any holes. The
sequence 1,2,3,10,11,12,15 gives a min hole sep of 3.
Num holes: Number of packet loss sequences. The sequence
1,2,3,10,11,12,15 gives a num holes of 2.
FEC mode: The CoP3 FEC mode
FEC drops: Number of RTP packet drops in the main stream that the FEC could
not correct
C-FEC drops: Number of IP packets in the column-FEC streams dropped
R-FEC drops: Number of IP packets in the row-FEC streams dropped
