Võrgustikutõuke

Võrgustikutõuke, also known as network jitter, refers to the variation in the packet arrival times in a network. It is a critical parameter in assessing the quality of service (QoS) in real-time applications such as voice over IP (VoIP), video conferencing, and online gaming. Jitter can be caused by several factors, including network congestion, routing changes, and the variability in packet processing times at network nodes.

The impact of jitter on real-time applications can be significant. It can lead to delays in packet delivery, causing audio or video streams to stutter or become choppy. In VoIP systems, jitter can result in distorted or unintelligible speech. To mitigate the effects of jitter, various techniques are employed, such as buffering, jitter buffers, and adaptive algorithms that adjust to changing network conditions.

Jitter is typically measured in milliseconds and is often expressed as the standard deviation of the inter-arrival times of packets. Network administrators and engineers monitor jitter levels to ensure that they remain within acceptable thresholds for the applications being supported. Techniques such as Quality of Service (QoS) policies, traffic shaping, and the use of dedicated network paths can help in reducing jitter and improving the overall performance of real-time applications.
