What Is Jitter and How to Minimize It?

Here we can see, “What Is Jitter and How to Minimize It?”

  • Nowadays, it frequently occurs that connections are impacted by a variety of irritating occurrences, such as jitter, packet loss, or excessive ping/latency concerns.
  • You can take some simple steps to reduce or eliminate them, such as switching to a different Ethernet cable or choosing wired connections over Wi-Fi.

These days, connections frequently experience a variety of irritating situations. High ping values, packet loss, and jitters are just a few of these events that could harm your connection.

It’s extremely likely that the problem, if it suddenly begins to arise, will eventually resolve itself. However, sometimes you may be the one responsible for these occurrences, in which case you have the authority to address the problems.

What is jitter?

When the delay time (ms) of data packet transmissions begins to vary, this is known as jitter (network jitter). It differs from latency (delay), which is the amount of time it takes for packets to move between two points.

Let’s imagine, for instance, that the delay for a single packet is about 2 ms. This is known as jittering when multiple packets have dramatically varied delay values. In networking and telecommunications, this condition is undesirable since it may impair connection performance or possibly result in packet loss.

What causes jitter?

You can avoid or reduce these undesirable deviations more successfully if you are aware of their sources. So what specifically triggers jittery networks? Bad routing appears to be the primary source of this problem.

Forwarded packets are forced to change routes repeatedly during their transmission duration if routing differs significantly within the same network, which can raise or decrease delay. In actuality, jittering is this variance in delay.

Network congestion is a different, commonly recognized factor. Naturally, putting a lot of strain on a network will cause frequent route changes, which in turn cause latency differences.

Let’s phrase it more simply. Packets won’t always pick the quickest route if there are several options for connecting your network devices. To cut down on transmission time, they will be randomly distributed simultaneously on all of the routes.

The packets that took the quickest path (with the fewest hops) will almost likely arrive before those that followed the longer routes (with more hops).

As a result, the delivery time for each package will vary (e.g., one packet gets sent in 10 ms, another takes 40 ms to reach its destination). It commonly manifests itself on your network as jitter, which is this variance in delay.

How to test jitter?

1. Use Speedtest by Ookla’s desktop app

    1. Install Speedtest by Ookla on your computer by downloading it.
    2. Open it, then grant it access to your location.
    3. When the speed test is over, press the GO button.
    4. In the top-right portion of the screen, select More.
    5. From the Result History section, choose your test.
    6. Review the Jitter section’s value.

Jitter tests can also be carried out using additional specialized software programs, such as PRTG Network Monitor. Although you might learn more about your network with this application, it will be much more challenging to use than Speedtest by Ookla.

2. Use Windows’ built-in tools

    1. On your keyboard, press the Win key.
    2. Right-click Command Prompt and choose “Run as administrator” after typing CMD.
    3. In the CMD window, enter ping 192.168.0.1 -n 30.
    4. Await the ping test to finish.
    5. Pay attention to each ping’s time value.
    6. By summing up all ping numbers and dividing them by their total, you may determine the average latency (30 in our case)
    7. If there are any differences between the samples, identify them and set them away.
    8. Add them all up, and divide them by the number of samples minus 1
    9. You sum up the values you previously obtained and divide them by the variety of differences you discovered, or the variety of values less than one. If you compare the jitter to the average latency, the latter should never be greater than 15% of the former.

How to fix jitter?

    • To solve Ethernet issues, upgrade your Ethernet cable (Cat 6 is currently your best choice)
    • Whenever possible, choose wired connections over Wi-Fi.
    • Make use of a robust router that can manage the entire bandwidth of your Internet connection.
    • Choose high-speed Internet services like fiber optics.
    • If your connection fluctuates substantially in latency and is unstable, switch your Internet service provider.
    • Using Wi-Fi, use as many different channels as possible to distribute your devices.
    • Avoid sending significant amounts of data over VoIP (e.g., torrenting, streaming)
    • Set your router’s buffer size to a small value.
    • Aim to prevent buffer bloat (when your router builds an excessive queue instead of dropping unsent packets)

Jitter is not something you would want in your connection, all things considered. However, you may take some simple steps to reduce or completely eliminate it, such as switching to a wired connection instead of Wi-Fi or changing your Ethernet cable.

You can perform a few tests to see whether your suspicions that you’re experiencing jitter are accurate. If you do notice jitter and try to address it on your end with no success, your ISP may be to blame. You ought to get in touch with them in this situation.

User Questions

1. How is jitter minimized?

Using a jitter buffer is one of the best strategies to reduce internet jitter. A VoIP system’s jitter buffer is a useful component. Incoming voice packets are delayed and stored to accomplish their task. Before delivering traffic to the receiver, they wait for a buffering period of between 30 and 200 milliseconds.

2. How much jitter is okay?

Jitter needs to be less than 30 ms. More than 1% should not be lost in a packet. The maximum network latency should be 150 ms. Due to the one-way delay, the round trip time (RTT) would be 300 ms.

3. What occurs if the jitter is excessively high?

High jitter levels suggest a slow network and delayed packet delivery. High jitter causes packets to arrive out of order and render them useless. For instance, many delays may muddle the conversation if you are making calls using a VoIP phone system.
