Impairment Help

Delay, Delay Variation (Jitter) and Loss are applied to all packets transmitted by the selected interface.

Delay:

A basic time delay, specified in milliseconds.

Example:

42

Delay Variation (Jitter):

a modifier applied to the basic delay. Each packet is delayed by an additional random length of time in the range: plus-minus Delay Variation.

Note 1: The actual delay for a packet is calculated as the sum of Delay and the random Delay Variation value and can not be negative, so negative values are clamped at zero.

Note 2: If Delay Variation is non-zero, the Delay parameter has to be non-zero as well.

Example:

22

Loss:

A percentage of random packet loss. Each packet has X percent chance of being dropped.

Example:

7
