Latency and jitter
- [Instructor] Latency is measured as amount of the time taken to transmit a packet between a sender and a receiver. Several factors cause a delay in data transmission such as packet processing time, packet transmission time, signal propagation time, and other delays caused by routers and other network devices. On an end to end connection, latency can be measured as one-way delay and a two-way delay. A two-way delay, or round trip delay, is helpful, especially when a connection consists of multiple links where the link condition asymmetric. On a small network with one short link between two nodes, a round trip delay can be simply two times the one way delay. However, the link condition depends on the media, interference, and environmental factors Jitter or delay variation is another useful metric that can be measured from the delays over time. Therefore, on a single connection between a satellite and a ground station at least…
