Abstract:
A system including a network interface card (NIC) associated with a Media Access Control (MAC) address and a host operatively connected to the NIC. The NIC includes a default hardware receive ring (HRR), a plurality of non-default HRRs, and a hardware classifier. The hardware classifier is configured to analyze an inbound packet using a destination Internet Protocol (IP) address and to send the inbound packet to one of the plurality of non-default HRRs if the inbound packet is a unicast packet, and to send the packet to the default HRR if the inbound packet is an inbound multi-recipient packet. The host includes a plurality of virtual NICs (VNICs) and an inbound software classifier, that includes a plurality of software receive rings (SRRs) and is configured to obtain inbound packets from the default HRR, and to determine to which of the plurality of SRRs to send a copy of the packet.
