Packet delay variation
open-in-new
<p>In <a href="/facts/Computer_networking/3w5RM99p">computer networking</a>, packet delay variation (PDV) is the difference in <a href="/facts/End-to-end_principle/6RkKmdUm">end-to-end</a> <a href="/facts/One-way_delay/gBKzavMl">one-way delay</a> between selected packets in a <a href="/facts/Traffic_flow_(computer_networking)/Yp8UP6ys">flow</a> with any <a href="/facts/Packet_loss/6fuIcFHk">lost packets</a> being ignored. The effect is sometimes referred to as packet jitter, although the definition is an imprecise fit. </p>
