Abstract
A method for processing packets that includes receiving a first packet for a first virtual machine by a network interface card (NIC), classifying the first packet using a hardware classifier, where the hardware classifier is located on the NIC, sending the first packet to a first one of a plurality of receive rings based on the classification, sending the first packet from the first one of the plurality of receive rings to a first virtual network interface card (VNIC), sending the first packet from the first VNIC to a first interface, and sending the first packet from the first interface to the first virtual machine, where the first virtual machine is associated with the first interface, where the first VNIC and the first virtual machine are executing on a host.
