Switch operation system loading method based on SDN mode

The invention relates to the network technology field and the fixing member technology field, especially relates to the software definition network technology and particularly relates to a switch operation system loading method based on an SDN mode. The method comprises steps that 1), a UEFI fixing member starts a switch hardware platform, and a switch management port network interface card driver is loaded; 2), an IP address of a switch management port and an IP address of an SDN controller are set by a user and are stored; 3), a communication link between the SDN controller and the switch is realized through the IP addresses; 4), at the SDN controller end, a switch operation system mirror image is issued to the switch according to network demands; and 5), a system loader in an UEFI fixing member carries out leading loading for the switch operation system mirror image acquired from the SDN controller. Through the method, more elastic network equipment function control and more flexible network topology adjustment can be realized, and convenience is provided for rapid networking.
