Abstract

A network processor may receive a request from an endpoint device to increase a priority of traffic associated with a first quality of service class indicator, which is associated with a first packet data session quality of service label, and may increase the priority of the traffic in response to the request by sending an instruction to a network element to adjust a mapping of the first quality of service class indicator to a second packet data session quality of service label for the traffic. The network element may label packets in the traffic with the second packet data session quality of service label instead of the first packet data session quality of service label, and components of the network may process the packets labeled with the second packet data session quality of service label with a greater priority than packets labeled with the first packet data session quality of service label.
