The invention discloses an SDN flow table automatic one-key deployment system, including a front end, which is used for inputting user instructions, generating flow table information, determining the type of flow table to be configured, and displaying various associations between existing network devices Relationship, the flow table information is encapsulated with a graphical control interface; a graphical unit is used to generate a graph of the network device, and the graph is associated with the configured flow table of the flow table configuration unit; the flow table configuration unit is used to configure the selected The configuration interface of the flow table information in the two network nodes, which corresponds to the user command enumeration to generate the flow table information to be issued, and associates the configured flow tables of the two network nodes; the flow table type data set unit is used to determine the correspondence of the graph the type of the flow table; a form submitting unit, configured to send the flow table information to be delivered to the network node. The invention realizes graphic connection network control, simplifies the control mode of issuing the flow table in the SDN network equipment, and reduces the professional requirement of the operator for the sending of the flow table.
