Hi Benny, I need to calculate Mean Jitter & Deviation Jitter , as per RFC 3611 section 4.6 Stats Summary Block Is this calculation below is mean jitter sess->avg_jitter = (jitter + sess->avg_jitter * sess->stat.rx.jitter.count) / (sess->stat.rx.jitter.count + 1); And also Standard deviation jitter for the same. -- Thanks & Regards, Ravi Inder Singh -------------- next part -------------- An HTML attachment was scrubbed...
