LLQ priority on congested link, Delay and jitter

Hi

I have a MPLS link configured with LLQ priority on the voice class and CBWFQ on the data classes applied outbound to the ISP, it's a layer 2 Wimax link and the ISP has a similar qos config for return traffic on the PE router. The data classes burst when the voice class is not in use.

In terms of jitter and latency would it be any higiher on the link when the data classes have congested the link and a voice packet gets to the router. It might not be much but i suppose the router having to prioritise the traffic and the fact that data traffic has already been sent should affect this slightly. If so anyone know what would be the normal increase in this case.

tnx
