Jitter Measurement

What is Jitter?
Jitter is an unwanted variation of one or more signals in electronics and telecommunications. In the context of the Genie - Monitoring platform solution, jitter is the variation in the ICMP response time.

Where is Jitter Measurement needed?
Jitter measurement is usually needed to see the quality of streaming protocols such as:
  • IP Telephony
  • IP Television
  • Video conferencing
  • Video and music streaming
and more...

The Product Support
The ICMP agent has a functionality that enables it to measure the jitter of remote stations. The method of measuring the jitter is to send multiple ICMP requests in a given monitoring cycle to the IP address, and then measure the response time of those requests. The user can determine the number of requests that compose a single cycle. The output, returned by the agent, is processed. The average, mean, Max, Median, and standard deviation are calculated.
The product supports limits on several statistical functions that can be applied to the differences in the response time, such as:
  • Mean value
  • Standard deviation
and others...
When a device crosses a specified limit, an event handler, which runs a user command, is launched.
