Abstract

The invention provides a method and network card for a physical machine to access to a virtual network. The method comprises: utilizing the network card of a physical machine to package the original data packet sent by the physical machine to a virtual network to form a VXLAN(Virtual Extensible LAN) data packet, and to send the VXLAN data packet to the virtual network; utilizing the network card of the physical machine to disassemble the VXLAN data packet sent to the physical machine by the virtual network to obtain the original data packet in the VXLAN data packet, and to send the obtained original data packet to the physical machine; and building an address mapping table used for displaying the address mapping relation between an IP address and an MAC address in the network card of the physical machine. According to the invention, the network card of the physical machine is equivalent to a virtual tunnel port to realizes functions, and directly replaces the virtual tunnel port, thereby allowing the physical machine to access to a virtual network; in addition, compared with a special-purpose software gateway, the network card has better performances, and is much cheaper than an SDN TOR switch.

Description

technical field [0001] The present invention relates to the technical field of network equipment management, in particular to the technical field of physical machines and virtual machines, and specifically relates to a method for a physical machine to access a virtual network and a network card. Background technique [0002] A physical machine is a name for a physical computer as opposed to a virtual machine. The physical machine provides the virtual machine with a hardware environment, sometimes called "host" or "host". A virtual machine (Virtual Machine) refers to a complete computer network card that is simulated by software and has complete hardware network card functions and runs in a completely isolated environment. The virtual network card generates a new virtual image of the existing operating network card, which has exactly the same functions as the real windows network card. After entering the virtual network card, all operations are carried out in this brand new ...
