ABSTRACT:
An apparatus for classifying data packet protocol values in a packet architecture comprising a packet header and a packet payload including an extension header is described. The apparatus comprises a processor configured to specify a packet protocol value in an extension header of a type requiring mandatory examination by at least one device receiving a packet. For example, an apparatus comprises a packet processor unit configured to generate a data packet comprising the extension header, wherein the extension header specifies a packet protocol value, wherein the extension header is a mandatory extension requiring examination by a receiving apparatus to which the packet may be sent, wherein the packet protocol value is also carried in one or more additional headers in the packet, and wherein the extension header enables classifying the packet based on the packet protocol value and without traversing the additional headers in the packet.
