Jitter Control in Networking Definition
Jitter is defined as the variation in the packet arrival times. This is usually measured as standard deviation. High jitter is uneven quality of sound or video. Jitter can be controlled by the following technique.
Calculate the expected transmission time for each hop in the path, check whether a packet has arrived early or late by comparing it with the expected time. If it has arrived early, send it late. Otherwise send it immediately.
Jitter Contol in applications like video on demands, jitter can be removed by buffering. But for real-time applications like telephony and video conferencing buffer induces delay and is not desirable.
