    Abstract: A network device may receive a packet including control tags in a header portion of the packet and may extract candidate tags from the control tags in the header portion of the packet. The network device may compress, using a first lookup table, the candidate tags to obtain keys corresponding to the candidate tags, where each of the keys is represented in a compressed format relative to the corresponding candidate tags. The network device may further determine a final key based on the first keys and determine a priority class for the packet based on a lookup operation of the final key into a second lookup table. The network device may further write the packet, or a reference to the packet, to a selected priority queue, of a number of priority queues, where the priority queue is selected based on the determined priority class.
