Claim 1

Independent Claim 180 words

A method comprising: receiving, by a network device, traffic; determining, by the network device, whether the traffic is host bound traffic or non-host bound traffic; determining, by the network device and based on a classification scheme defined by a user of the network device, a classification of the traffic when the traffic is host bound traffic; determining, by the network device and when the traffic is host bound traffic, that a bandwidth is unavailable for forwarding the traffic to a host component of the network device; assigning, by the network device and based on the classification, the traffic to a queue associated with the network device based on determining that the bandwidth is unavailable for forwarding the traffic to the host component; determining, by the network device, that a different bandwidth is available for forwarding different traffic to the host component; and forwarding, by the network device, the different traffic to the host component, without assigning the different traffic to any queue, based on determining that the different bandwidth is available for forwarding the different traffic to the host component.
