Abstract

Abstract A network device component receives traffic, determines whether the traffic is host bound traffic or non-host bound traffic, and classifies, based on a user-defined classification scheme, the traffic when the traffic is host bound traffic. The network device component also assigns, based on the classification, the classified host bound traffic to a queue associated with network device component for forwarding the classified host bound traffic to a host component of the network device.

Claims Analysis

Total Claims: 23
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.

Claim 9
Dependent Claim 14 words
The method of claim 1 , where the network device includes a firewall filter.
Claim 10
Dependent Claim 32 words
The method of claim 1 , further comprising: receiving, from the user, one or more changes to the classification scheme; and changing the classification scheme based on the one or more changes.
Claim 11
Dependent Claim 22 words
The method of claim 1 , where the classification scheme is based on default classifications that are pre-configured in the network device.
Claim 12
Dependent Claim 164 words
A network device comprising: one or more processors to: receive traffic, determine whether the traffic is host bound traffic or non-host bound traffic, determine, 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, determine, when the traffic is host bound traffic, that a bandwidth is unavailable for forwarding the traffic to a host component of the network device, assign, based on the classification, the traffic to a queue of a plurality of queues based on determining that the bandwidth is unavailable for forwarding the traffic to the host component of the network device, determine that a different bandwidth is available for forwarding different traffic to the host component, and forward the different traffic to the host component, without assigning the different traffic to any queue of the plurality of queues, based on determining that the different bandwidth is available for forwarding the different traffic to the host component.
Claim 13
Dependent Claim 164 words
A network device comprising: one or more processors to: receive traffic, determine whether the traffic is host bound traffic or non-host bound traffic, determine, 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, determine, when the traffic is host bound traffic, that a bandwidth is unavailable for forwarding the traffic to a host component of the network device, assign, based on the classification, the traffic to a queue of a plurality of queues based on determining that the bandwidth is unavailable for forwarding the traffic to the host component of the network device, determine that a different bandwidth is available for forwarding different traffic to the host component, and forward the different traffic to the host component, without assigning the different traffic to any queue of the plurality of queues, based on determining that the different bandwidth is available for forwarding the different traffic to the host component.
