Abstract
A system includes a physical NIC associated with the computer and including receive rings for storing network traffic addressed to the VNIC, where the receive rings include a local receive ring for storing local traffic and a forwarding receive ring for storing forwarding traffic. The physical NIC further includes a hardware classifier configured to register a local Internet Protocol (IP) address associated with the VNIC in a lookup table, receive a packet including a destination IP address, classify the packet as local traffic or forwarding traffic using the lookup table, and store the packet in the local receive ring or the forwarding receive ring based on the type. The VNIC is configured to retrieve the packet from the receive ring, and process the packet in a type-specific manner based on the receive ring where the packet was stored, where the type-specific manner is different for local traffic and forwarding traffic.
