Abstract:
1. A method for identifying a quality of service (QoS) classification of a packet in a network processor, the method comprising: providing a table that may be indexed into by one or more priority values, each having a maximum of N values, to retrieve a QoS classification having a maximum of M values, wherein M is less than N; receiving a data packet in a stream of data packets, wherein the data packet comprises a plurality of priority indicator values; extracting at least two different priority indicator values of the plurality of priority indicator values from the data packet; converting the at least two different priority indicator values into a single resultant priority value by; utilizing the single resultant priority value to index into the table; in response to utilizing the single resultant priority value to index into the table, extracting an entry from the table that corresponds to the single resultant priority value as a QoS classification of the data packet; and utilizing the QoS classification of the data packet for subsequent processing of the data packet.
