Jitter, or network jitter, is the variance in time delay in milliseconds (ms) between data packets over a network. It is a disturbance in the typical sequence of sending data packets.
The technical term for jitter is “packet delay variance”. Jitter is negative, and in latency sensitive applications, can be detrimental to the user experience.
Network Jitter Example
In the event that you have “computer A” speaking with “computer B”, the two will transfer data packets. Over a healthy network, the packets travel in equal intervals. This will permit the receiving computer to process the data. When there is a circumstance with jitter, these intervals become disrupted.
On the off chance that over a typical connection there is a 10 ms latency delay between packets, this could become 50 ms with jitter. This makes it hard for the receiving computer to process the data.
How You Transfer Data
To understand jitter, we need to examine how to transfer data. When visiting a website, the website is a collection of data packets. The packets get sent from a server, over a network to your computer, and loaded by your web browser.
The data travels in manageable size packets. The packets travel with the greatest number of that can fit inside the available bandwidth of the network, and that a web browser can simultaneously process. Latency is the measurement for the speed of the packets.
The packets travel exclusively based upon these metrics. In a perfect world, all data packets will travel at even circulations of time. In our example above, a 10 ms delay between each packet.
With jitter this becomes varied, and the results are terrible.
With high jitter you could have 3 packets not sent when requested. Then when the time lapse completes, each of the 3 can arrive at once. This will cause an overload for the requesting computer. This circumstance leads to congestion and packet misfortune.
The Effects of Jitter
Jitter causes network congestion and packet misfortune.
Congestion is like an automobile overload on the highway. In an automobile overload, vehicles can’t move forward at a reasonable speed. Like the road turned parking lot, in congestion all the packets come to an intersection at the same time. Nothing can get loaded.
The second negative effect is packet misfortune. In the event that packets arrive at unexpected intervals, the receiving computer can’t process the data. The result is missing data, or better called packet misfortune.
This has negative effects for video viewing. In the event that a video becomes pixelated and is skipping, the network is experiencing jitter. The result of the jitter is packet misfortune.
In the event that you are playing an online game, the effect of packet misfortune can be a player begins skipping around on the screen. Even worse, the game goes starting with one scene then onto the next, skirting some portion of the game play.
In voice over IP (VoIP), the conversation will be hard to hear. The reason isn’t all the voice data arrives.
How Systems Compensate
Realizing jitter is an inherent blemish in networks, there are systems in place to compensate for this. The primary system is buffering. This provides a literal “buffer” time for covering jitter. This will ensure there is no noticeable difference in the quality of streaming, loading, or downloading.
Network jitter is hard to solve due to unpredictability. This is what makes its effects so visible. Ensuring a quality network connection, enough bandwidth, and predictable latency can help reduce network jitter.
Jitter Speed Test
Jitter is any deviation in, or displacement of, the signal pulses in a high-frequency digital signal. The deviation can be in terms of amplitude, phase timing or the width of the signal pulse.
