TWAMP Light: IS-IS: Unidirectional link delay and delay variation measurements

This feature enables TWAMP Light to measure unidirectional link delay and delay variation for use by IS-IS. Supported measurements include average, minimum, and maximum link delay, as well as average link delay variation. Measurements can be performed using accelerated or periodic intervals. Accelerated measurements enable IS-IS to react more quickly to significant changes in link performance, while periodic measurements provide ongoing monitoring and advertisement of link-delay information. You can use these measurements to support path-selection decisions based on observed network latency and delay variation.
