一种SDN设备自动上线的方法、SDN设备和控制器
摘要：
本发明实施例公开了一种SDN设备自动上线的方法、SDN设备和控制器，涉及通信技术领域，用以实现SDN设备自动上线，进而简化SDN网络中设备上线的工作流程，提高设备上线效率，做到设备即插即用、即插即管。该方法包括：待上线SDN设备广播封装了虚拟局域网VLAN标识的DHCP发现报文；接收第一控制器广播的第一DHCP响应报文；将接收第一DHCP响应报文的第一端口置于VLAN标识；采用第一端口广播DHCP请求报文；通过第一端口接收第一控制器广播的DHCP应答报文；当该SDN设备与该控制器建立了OpenFlow连接之后，接收该控制器发送的出向报文，出向报文携带了链路层发现协议LLDP消息。
摘要（英）：

The embodiment of the invention discloses an automatic online method of an SDN device, the SDN device and a controller, and relates to the field of communication technology. Automatic online of the SDN device is realized to simplify the device online working flow in an SDN, improve the device online efficiency and realize plug and play and plug and management of the device. The method comprises the following steps: broadcasting a DHCP discovery message packaged with a virtual local area network VLAN identifier by an to-be-online SDN device; receiving a first DHCP response message broadcasted by a first controller; setting a first port receiving the first DHCP response message in the VLAN identifier; broadcasting a DHCP request message by using the first port; receiving a DHCP answer message broadcasted by the first controller through the first port; and after the SDN device establishes an OpenFlow connection with the controller, receiving an outbound message sent by the controller, wherein the outbound message carries a link layer discovery protocol LLDP message.
