Hi everybody, I'm trying to create a script to determine rtp packet lost using
tcpdump and awk. And It works, but also i'm trying to create a script to
calculate the jitter but i don't have an idea how to do it. Maybe there is a
tool or someone has an idea.
#!/bin/sh
#Scrip To calculate rtp packet lost.
sudo /usr/sbin/tcpdump -r sample_test.pcap -T rtp | awk '{seq=$8; time=$1;
split($2,src,"."); split($4,dst,"."); if (seq != (oldseq+1)) {if (oldseq != "")
{print "Time:"time " src host:"src[1]"."src[2]"."src[3]"."src[4]" src
port:"src[5]" dst host:"dst[1] "." dst[2] "." dst[3] "." dst[4],"port:"
substr(dst[5],1,index(dst[5],":")-1),"Seq:"seq,"OldSeq:"oldseq};
lost=lost+seq-oldseq};oldseq=seq;}' >>test_file can anybody helpme or does any
body did a script for the jitter. thanks Best Regards
