Delay, Delay Variation (Jitter) and Loss are applied to all packets transmitted by the selected interface.
A basic time delay, specified in milliseconds.
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.
A percentage of random packet loss. Each packet has X percent chance of being dropped.
