Subject: [LARTC] How to measure jitter & packet loss?

Inter-packet gaps if too big may cause real-time application to have
jitters. But how do i measure the jitter if supposedly i send out a tcp/udp
stream??
Attached is an extract of tcpdump data.
Any information on how to post-analyse tcpdump for jitter, packet loss is
very very much appreciated.
Regards.
