description A method, a system, and a computer program product is disclosed for identifying a quality of service (QoS) classification of a packet in a network by a network processor. The method comprising: providing a table wherein a priority value with a maximum of N values is used as an index into the table to retrieve a QoS classification having a maximum of M values with M less than N; receiving a data packet in a stream of data packets; extracting at least two priority indicator values from the packet; converting the at least two priority indicator values into a priority value; utilizing the priority value as an index into the table; extracting the entry in the table corresponding to the priority value as the QoS classification of the packet; and utilizing the QoS classification for subsequent processing of the data packet.
