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.
Claims20
A method of processing packets in a network device, the method comprising:
- receiving a data packet at a port of a network device, wherein the data packet includes at least one externally assigned Quality of Service (QoS) attribute that is compliant with a communications protocol;
- assigning at the network device at least one internal QoS attribute for use in processing the received data packet within the network device, wherein the at least one internal QoS attribute is based on the at least one external QoS attribute and wherein the at least one internal QoS attribute is independent of a specific communications protocol;
- and
- processing the data packet through the network device using the assigned at least one internal QoS attribute.
