In networking, jitter refers to the variation in the delay between packets arriving at their destination. It is a measure of the consistency of packet arrival time. Jitter can occur due to network congestion, routing changes, and other factors that affect the transmission of packets over a network.Jitter can be particularly problematic for real-time applications, such as voice and video conferencing, where a consistent delay is required for a smooth and seamless user experience. High levels of jitter can result in choppy audio or video, dropped frames, and other issues that can negatively impact the quality of the communication.Jitter is typically measured in milliseconds (ms), and it is important to minimize jitter as much as possible to ensure a high-quality user experience. Network engineers use various techniques to manage and reduce jitter, such as implementing quality of service (QoS) policies, optimizing network routing, and using buffering and queuing mechanisms.
