在一些情况下，SDN控制器南向接口的实现方案中，在下发不同厂商的设备时，需要进行硬编码，并且需要重新启动SDN控制器以支持不同的设备。

基于本示例的上述配置文件，以A厂商为例，用户通过SDN控制器给指定的设备的接口配置IP地址的实现过程，如图5所示，可以包括：
步骤501，用户通过SDN-O配置A厂商的网络业务，SDN-O向SDN控制器发送配置请求，该配置请求中携带用户指定设备的信息、指定接口的信息、以及指定接口的IP地址。
步骤502，SDN控制器接收所述配置请求，根据所述用户指定设备的信息中指示的设备类型，读取对应的“控制器配置模型和A厂商设备南向接口模型对应关系的配置文件”。
步骤503，SDN控制器根据上述的配置文件中描述的对应关系，将用户配置的数据构建为A厂商的设备模型数据。
步骤504，SDN控制器将构建好的设备模型数据通过设备南向配置通道下发到对应A厂商的设备。
