The table above, taken from IEC 61850-90-4, shows that 4 classes of services should
be considered when using QoS services: The Gold class for SCADA and Automation
messages, the Silver class for management messages, the Bronze class for other
kinds of data and the Best Effort class (DSCP value 0) for legacy equipment with no
DSCP priority information.
If the application does not have a special reference to be used, the table below can
be used as reference for DSCP-to-CoS mapping. reference:
