摘要： A method for notifying a packet destination that includes receiving a packet by a network interface card (NIC), where the packet destination is a destination of the packet, classifying the packet, forwarding the packet to one of a plurality of receive rings on the NIC, determining whether the one of the plurality of receive rings comprises space to store the packet, dropping the packet if the receive ring does not comprise the space to store the packet, and sending a notification message to the packet destination, where the notification message indicates that the packet was dropped by the receive ring.

摘要： 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.
