Some speed tests will include a jitter score. This is the variation between response times. A good connection will have a reliable and consistent response time, which will be shown by a low jitter score. As a general rule, jitter should be below 30ms. Jitter is the variation between response times. Good connections have a reliable and consistent response time, which is represented as a lower jitter score. The higher the jitter score, the more inconsistent connection response times are, which manifests in choppy voice calls or glitchy-sounding looking video quality.
Jitter causes poor audio quality in a call, usually in the form of choppy sound. Jitter is the variation in packet transit delays, measured in milliseconds. The lower your jitter is, the better.
The following are types of jitter you may encounter in the world of electronics:
Absolute Jitter: It is a measure of the deviation in time of a clock pulse edge from its ideal location.
Period Jitter: It refers to a variation between the ideal clock periods and actual clock periods. The effects of Period jitter are especially disruptive in synchronous circuitry, i.e., a central processing unit.
Inter-cycle jitter or Cycle-to-Cycle Jitter: This type of jitter refers to the difference in duration between successive clock periods. Also, excessive Inter-cycle jitter will nullify a microprocessor’s functionality.
Because of the varying delays within a broadband internet network, the time from when a packet is generated at the source until it is received at the receiver can fluctuate from packet to packet. This phenomenon is called jitter. For real-time services, keeping the packet intervals at the destinations within an acceptable range of what is generated at the source is crucial to maintaining the integrity of service.
Some business internet providers implemented their broadband network to only deliver a “best-effort” transmission, which means the packet arrival timing could be out of sync with the original stream created at the source. As mentioned before, this makes it impossible to run real-time services like certain kinds of applications based on cloud computing and VoIP. Perform the Jitter Speed Test.
