Question:

I want to know the overall Jitter????
Is there any formula to find ???

ANSWER: Hi Srinivasarao


Many thanks for your question.

If I may I'd like to point you to a very good
explanation of jitter by Cisco themselves.
There's plenty to discuss regarding jitter and I
fear I would have used up my character limit.

Hope this helps,

Hi Srinivasarao,

I must confess I'm not an expert on this subject -
here's the best document I could find. I'm reading this
myself now too....
