Method and device for transmitting message

The invention discloses a method and a device for transmitting message. The method is as follows: a virtual switch receives the first flow stable and a second flow stable sent by the SDN controller; if the message is matched with the first flow table while the virtual switch receives the message from the virtual machine, the virtual switch sends the message to the virtual NAT device via the first flow table, the virtual NAT device does NAT conversion on the source IP address of the message and sends the conversion NAT message to the virtual switch; if the message is matched with the second flow table while the virtual switch receives the message from the virtual NAT device, the virtual switch uses the second flow table for executing VXLAN packaging operation on the message and sends the VXLAN packaged message to the VXLAN gateway. According to the embodiment, the NAT conversion is avoided to the message of the virtual machine by the VXLAN gateway, the CPU resource of the VXLAN gateway is saved and the processing performance of the VXLAN gateway is reduced.
