US Patent 7715416 Generalized serialization queue framework for protocol processing

A method for processing packets. The method includes receiving a first packet, wherein the first packet is associated with a first protocol, classifying the first packet using a protocol associated with the first packet, sending the first packet to a first receive ring based on the classification, sending the first packet from the first receive ring to a first virtual network interface card (VNIC) based on an operating mode, sending the first packet from the first VNIC to a first protocol specific virtual network stack (VNS), wherein the first protocol specific VNS is configured to only process packets associated with the first protocol, and processing the first packet by the first protocol specific VNS to obtain a first processed packet.
