Hi,

It's based on the RTP timestamp and packet timestamp.
If you have silence frames or DTMF in the trace that might throw
the calculations off. I'm unsure if they work well for all codec types.
I think it's based on G.711(PCMA/PCMU).
Packet loss is missing sequence number.
Hope this helps.

Ämne: [Wireshark-users] what does RTP statistics mean when Wireshark runon
server ??
Hello All,
Im running Wireshark on server which streams RTP packets to a client.
I see some values for packet loss, mean jitter and max delta.
Since Wireshark is running on server , on what basis it calculates
packet loss / jitter / delta .
I understand the importance of these measurements when wireshark runs
on client but it relly bothers me when i see values for these metrics
even on the server.
In case of UDP packets , there is no ACK being sent even if the packet
it lost , so how does wireshark calculate packet loss.
So what do these metrics(packet loss or jitter or delta ) mean when
wireshark run on a server ?
