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.

The process for preparing the alewives comprises mixing single-wall carbon nanotubes with 100% sulfuric acid or a superacid, heating and stirring, and slowly introducing water into the single-wall carbon nanotube/acid mixture to form the alewives. The alewives can be recovered, washed and dried. The properties of the single-wall carbon nanotubes are retained in the alewives.
