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.
