Techniques are described for applying double experimental (EXP) quality of service (QoS) markings to Multiprotocol Label Switching (MPLS) packets. According to the techniques, an edge router of an MPLS network is configured to map a Differentiated Services Code Point (DSCP) marking for customer traffic to at least two EXP fields of at least two different labels included in a MPLS packet encapsulating the customer traffic. In this way, the edge router may map the full DSCP marking across the first and second EXP fields to provide full resolution QoS for the customer traffic over the MPLS network. The techniques also include a core router of an MPLS network configured to identify a QoS profile for a received MPLS packet based on a combination of a first EXP field of a first label and a second EXP field of a second label included in the MPLS packet.
