Jitter vs. Latency: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 3, 2024
Jitter refers to the variability in time delay in packets arriving over a network, whereas latency is the time taken for a packet to travel from its source to its destination.
Key Differences
Jitter in networking refers to the irregularity or variability in time delay between data packets arriving over a network, which can lead to inconsistent communication quality. On the other hand, latency is the total time it takes for a data packet to travel from one point to another across the network. While jitter affects the stability of the connection, latency affects the speed.
In the context of network performance, jitter is critical in applications where timing is crucial, like video conferencing or online gaming, as it can cause disruption in the flow of data. Latency, however, represents the delay that affects the responsiveness of the network, being a key factor in how fast the data or information is accessed or transferred.
Jitter is usually measured in milliseconds and represents the variance in latency over time. For a stable network, jitter should be as low as possible. Conversely, latency is also measured in milliseconds, but it represents the average time taken for a signal to travel from source to destination, and lower latency implies a faster network.
Jitter becomes particularly problematic in real-time communications, where consistent timing is more important than the overall speed of transmission. In contrast, latency is more about the delay experienced overall, affecting how timely and responsive network communications are.
Both jitter and latency are crucial in assessing the quality of a network, jitter deals with the variability in delay of data packets, and latency deals with the overall delay of data transmission across a network.
