Abstract
A method for processing packets that includes receiving a first packet for a first target by a network interface card (NIC), classifying the first packet, sending the first packet to a first receive ring in the NIC based on the classification of the first packet, sending the first packet to a Network Layer from the first receive ring, sending a first virtual network stack (VNS) Instance ID associated with the first receive ring to the Network Layer, obtaining a first VNS Instance parameter using the first VNS Instance ID, and processing the first packet in the Network Layer using the first VNS Instance parameter to obtain a first network processed packet.
