ABSTRACT:
A network device adapted to process data packet traffic over a telecommunication network. The network device includes an ingress pipeline adapted to receive a data packet at a port of the network device. According to embodiments of the present invention, the data packet is characterized by an external QoS attribute having M bits. The network device also includes a processor adapted to form an internal QoS Profile associated with the data packet. The internal QoS Profile includes a QoS Profile Index having M+N bits and M and N are internally assigned. The processor is also adapted to process the data packet through the network device.
