Abstract
Exemplary methods receiving a packet of a virtual interface provisioned with a virtual interface QoS, wherein the virtual interface comprises a hierarchy of sub interfaces. The methods include selecting a virtual adjacency from a plurality of virtual adjacencies, wherein each virtual adjacency is associated with the virtual interface or a sub interface of the virtual interface. The methods include using the selected virtual adjacency to select a queue based on a priority of the packet, and store the packet in the selected queue. The methods include performing hierarchical scheduling based on the virtual interface QoS to select the queue from all sets of virtual interface queues of all virtual adjacencies, and sending the packet from the selected queue and a transport link identifier (ID) to a physical network processing unit.
