Jitter Test
Cut down on jitter across your network with a jitter test tool
Pinpoint what’s causing jitter within your network by routinely monitoring VoIP statistics
SolarWinds® VoIP & Network Quality Manager (VNQM) is specially designed to help network administrators manage and mitigate jitter. This tool can automatically monitor VoIP calls for metrics like maximum jitter and current jitter. With IP SLA capable nodes, SolarWinds VNQM can also allow you to start monitoring these metrics right away and drill down on call detail records for jitter and packet delays.
Build on jitter test results by monitoring, searching, and filtering VoIP calls
VNQM can allow you to search and filter VoIP calls based on the metrics found in call detail records. Working backwards, you can determine where jitter is highest by filtering VoIP calls according to most common error codes or call quality. This can indicate where jitter has exceeded acceptable levels.
Troubleshoot more proactively with an enterprise-grade jitter test tool
Making sure bandwidth and other network resources are provisioned appropriately can go a long way to reducing jitter. VNQM can list the top ten call quality issues and the distribution of VoIP and data for each designated gateway. This can make it easier to see how your VoIP capacity is being used, so you can adjust your QoS settings or network configuration as needed.
Get alerted when a network jitter test shows jitter approaching critical thresholds
A jitter test is a great way of zeroing in on where jitter is in your network, but VNQM can help you unlock even more detailed insights. This tool’s robust alerting system can send you an alert whenever jitter surpasses acceptable levels. You determine what acceptable levels are by setting predefined parameters for your network. These features are designed to help you drill down on performance issues caused by jitter quicker.
Correlate jitter with other performance issues in your network to deepen jitter test analysis
Jitter is often not an isolated issue—it can be closely related to latency, packet loss, bandwidth usage, and overall network performance. To properly manage jitter, you should look at it in conjunction with other factors. The PerfStack™ feature that can be used with VNQM is designed to allow you to correlate call performance metrics with jitter levels, WAN performance, and more on a common timeline to help deepen your jitter analysis.

Do you find yourself asking…
Jitter refers to intermittent delays in data packet transmission. This delay, measured in milliseconds, can negatively impact the quality of real-time applications like VoIP communication, streaming, and online gaming. Jitter shouldn’t be confused with network latency, which is the speed of your network traffic measured in milliseconds.
Jitter causes packets to be delivered at irregular intervals. A few packets might be sent with a small delay and then several packets might be sent all at once. This causes packet loss, which then causes a decline in the quality of real-time service.
If you’re using VoIP in your network, you are bound to have some packet loss and jitter—most of the time it won’t have a lasting effect on your connectivity. However, jitter can become a problem when it exceeds a certain level. The following are acceptable levels:
- Jitter below 30ms, ideally below 20ms
- Less than 1% packet loss
- Overall network latency less than 150ms
When you have high jitter levels over 30ms, you’ll notice a difference in VoIP call quality. Your calls might be distorted, warbled, or cut in and out.
Without conducting a jitter test, the exact cause of high jitter can be difficult to determine, especially in a large enterprise. However, since jitter is most commonly experienced during voice calls, internet connection issues are presumed responsible for most instances of jitter. The three most common causes of poor internet connection, and high jitter, are:
- Network congestion: Network congestion is by far the most common (and most obvious) cause of high jitter. If there are too many devices vying for bandwidth on the same network at the same time, your internet connection will slow to a crawl. Packets get dropped or delivered out of order, which causes jitter.
- Wireless networks: Wi-Fi is convenient and increases mobility in an enterprise, but it’s not always strong or stable enough to sustain clear video calls. What’s more, Wi-Fi connections are infamous for packet loss. With so many packets traveling through the air, it’s easy for some to get lost and cause jitter.
- Old or faulty hardware: An outdated modem, old or damaged Ethernet cable, or misconfigured router can all weaken your internet connection and cause jitter.
If the internet connection isn’t the problem, high jitter can also be caused by poor packet prioritization. Packet prioritization is a kind of Quality of Service (QoS) setting that allows you to prioritize certain kinds of network traffic, so they receive the most bandwidth, reducing network congestion. If your packets aren’t prioritized appropriately, business critical operations might not receive enough network resources to function efficiently.
