METHOD FOR SUPPROTING VIRTUAL NETWORK INTERFACE

摘要

PURPOSE: A virtual network interface support method is provided to reduce packet input time by removing time for copying packet data from a kernel memory area to a process memory area. CONSTITUTION: A CPU allocates a part of a memory area including a virtual process to a virtual network interface(S720). A network device stores a memory address of the virtual network interface and information about the virtual network interface(S740). The virtual network interface includes a pool area storing packet data, an input buffer area storing an address of the packet data, an output buffer area storing the address of the packet data, and a data area storing sizes of the input buffer area and the output buffer area.
