Now that we know what jitter is, let’s explore why it’s important to internet users and how it can be measured and reduced.

Jitter Definition and Explanation

Jitter refers to the variation in the time it takes for data packets to travel from one network device to another. This variation in delay can result in poor quality video and audio streaming, laggy online gaming, and slow internet speeds. Network congestion, signal interference, and routing inefficiencies can all contribute to jitter.

More specifically, jitter is measured in milliseconds and is the average difference between the actual arrival time and the expected arrival time of data packets. When the delay is consistent, it is known as fixed jitter, but when the delay varies, it is called random jitter. Jitter can be especially problematic for real-time applications like video conferencing, where even small delays can disrupt the flow of conversation.

Although jitter can be frustrating, it is not always possible to eliminate it entirely. Instead, network administrators and internet service providers use various tools and techniques to mitigate its effects, such as buffering, packet prioritization, and quality of service (QoS) policies.
