A device may receive traffic information associated with traffic flows assigned to a group of quality of service (QoS) treatment levels and travelling via a network device. The device may identify a group of target performance metrics corresponding to the group of QoS treatment levels. The device may determine a group of weight factors based on the traffic information and the group of target performance metrics. The group of weight factors may be determined such that a group of predicted performance metrics is optimized with respect to the group of target performance metrics. The device may output information identifying the group of weight factors to cause a parameter, associated with the network device, to be updated based on the group of weight factors. The parameter may relate to a manner in which the traffic flows are processed by the network device.
