Claim:
1. A method, comprising: receiving, by a network device, subscription information indicating that a particular device is subscribed to a service that provides link layer quality of service (“QoS”) treatment of traffic, associated with the particular device, wherein the subscription information specifies a set of link layer QoS levels that have been subscribed to by the particular device; storing, by a network device, inter-layer QoS information, the inter-layer QoS information indicating: receiving, by the network device, information indicating that an attachment procedure has been initiated between the particular device and a cellular telecommunications network with which the network device is associated; establishing, by the network device and based on the indication that the attachment procedure has been initiated, a set of bearers with the particular device, the set of bearers including one or more bearers that correspond to the set of link layer QoS levels; outputting, by the network device and to the particular device, information regarding the set of network layer QoS levels that are associated with the set of link layer QoS levels, wherein the outputted information allows the particular device to select a particular bearer, of the set of bearers, via which to output traffic to the network device; receiving, by the network device and from the particular device, traffic via the particular bearer; identifying, by the network device, via which bearer, of the set of bearers, the traffic was received from the particular device; determining, by the network device, a particular MPLS QoS level associated with the received traffic, the determining being based on the inter-layer QoS information and a link layer QoS level associated with the particular bearer, outputting, by the network device and to a packet data network (“PDN”), MPLS traffic that is based on the received traffic, the MPLS traffic including information indicating the particular MPLS QoS level that was determined based on the link layer QoS level associated with the particular bearer.
