Abstract: A method performed by a first network device for applying Quality-of-Service (QoS) on a virtual interface over a multi-path transport topology. The method includes receiving a packet of the virtual interface from a service home network processing unit (NPU), where the virtual interface has been provisioned with a virtual interface QoS, where the service home NPU has applied the virtual interface QoS on the packet, and where the packet includes a physical transport link identifier (ID) that identifies a physical transport link over which the packet is to be forwarded. The method further includes selecting a virtual adjacency based on metadata included in the packet and using the selected virtual adjacency to select a queue based on the physical transport link ID and store the packet in the selected queue. The method further includes performing scheduling to select the queue and sending the packet over the physical transport link.

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.
