摘要： In general, the invention relates to a method for transferring a packet. The method includes receiving the packet by a physical network interface, determining a virtual network interface card (VNIC) using a virtual switching table, where the VNIC is located on a computer operatively connected to the network express manager (NEM) via a chassis interconnect, and the VNIC is executing on a host operating system (OS) in the computer. The method further includes transferring the packet to a receive ring (RR) associated with the VNIC, wherein the RR is located on the NEM, providing the network express manager with a receive descriptor, transferring the packet to the guest OS memory using the receive descriptor, and notifying the guest OS that the packet is in the guest OS memory.
