ABSTRACT:
The invention relates to a method for processing a packet. The method includes receiving the packet by a physical network interface, determining a target virtual network interface card (VNIC) using the destination address and a virtual switching table (VST), transferring the packet to a receive ring (RR) associated with the target VNIC, wherein the RR is located on the NEM, determining, by the target VNIC, that the packet is in the RR, determining, by the target VNIC, that the packet is to be processed using an offload engine, transferring the packet to offload memory located on an offload computer, wherein the offload computer is operatively connected to the NEM via the chassis interconnect and wherein the offload engine is executing on the offload computer, processing the packet by the offload engine to obtain a processed packet, and transferring the processed packet to a target computer memory using the chassis interconnect.
