802.1p and DSCP QoS

There are two methods of QoS.

802.1p Class of Service is typically used for internal Layer 2 and some Layer 3 mapping. This marking typically will not survive being sent to the Public Internet and isn't universally supported.

DSCP Marking is used for Layer 2 and Layer 3 mapping. Not all networking devices or ISPs support DSCP Class of Service.
