Tracking Packets
You can use packet tracking to trace problems in IP, TDM, or serial networks
connecting Vmux devices to each other.
The sequence number is stamped in the 16-bit "seq-num" field in the TDMoIP
header. Consecutive packets will have consecutive sequence numbers. When the
sequence number reaches the maximum value (65535), it resets to 0.
The voice card in the remote Vmux device receives the packets from the network,
and analyzes the seq_num. The results of this analysis are summarized into 3
counters that appear in the 'Bundle Statistics' screen:
• Missing: The number of missing received packets. Only the total number of
missing packets is relevant, not which specific packets are missing. If the
network is 100% fine, then this field should be 0.
For example, if the received packets are numbered 1,2,3,5,6,7,8 then packet
no.4 is missing, and the "missing" counter is increased by 1.
• Longest Series: The largest burst of consecutive missing packets. This field
helps to identify a "bursty" network that drops bursts of packets.
For example, if the received sequence is: 36,41,42,43,44,45,46.... the longest
burst is 4 (because we missed 37,38,39,40, which is 4 consecutive packets.
• Freed: The number of duplicated packets that were received. Duplicate
sequence numbers are dropped by the receiving voice card, so a large number
of dropped, or freed, packets gives an indication of a 'duplicating network'.
For example, if the received sequence is: 6,7,8,9,6,6,10,11.... then packet
no.6 was duplicated twice by the network. The duplications are dropped by
the voice card, and the 'Freed' counter is increased by 2.
