How does Dante use DSCP / Diffserv priority values when configuring QoS?
Switches prioritize packets using what are called DSCP (Diffserv Code Point) values. Although Dante packet priority values have been chosen to make it simple to configure QoS with many switches, some switches require special configuration to recognize and prioritize specific DSCP values.
DSCP for Dante Hardware
The table below shows how Dante hardware devices apply DSCP packet priority values:
|High||Time critical PTP events||CS7||0x38||56||111000|
DSCP for Dante Software
Dante software does not apply DSCP to audio, control or PTP packets. This is because computers sometimes transmit packets in bursts, and a burst of packets tagged as high priority could block out other network traffic, causing issues for other applications.
