DVS and Dante Via do not use QoS

Hardware devices work hard to ensure that the high-priority, high-rate traffic is spread out time-wise.

DVS and Via are software-based, and thus subject to scheduling jitter.
If/when scheduling is delayed, they could end up sending a burst of large packets through the network. We decided not to QoS tag these packets to avoid having high-priority traffic “bursting” through the network.

Any additional delays in the network caused by not using QoS are assimilated into the overall latency budget.
