Abstract: Disclosed is an NAT implementation system, comprising: a controller and an Openflow switch. The Controller delivers a flow table and an improved group table. The Openflow switch receives the flow table and the improved group table, and matches, according to an address translation matching rule recorded in the flow table, a data packet that address translation needs to be performed on; and performs translation between a private address and a public IP address according to an address translation rule recorded in the improved group table, and sends the data packet out by using an address after translation. Further disclosed are an NAT implementation method and Openflow switch. By using the present invention, the flow table and the improved group table only need to be sent to the Openflow switch at once, and the Openflow switch does not need to frequently interact with the Controller, so that a forwarding delay of the data packet is shortened and the network transmission efficiency is improved.

Abstract: Disclosed are a method, device, system for detecting a data link, controller, and gateway. The method comprises: an SDN controller sends a GTP request message to a first UGW, and instructs the first UGW to send the GTP request message to another GTP endpoint in a GTP user plane signaling format; the SDN controller receives a GTP response message from the first UGW, and detects a data link between the first UGW and the another GTP endpoint according to the GTP response message, the GTP response message being corresponding to the GTP request message. The disclosure solves the problem in the prior art that logic of a user plane and logic of a control plane are unclear during detection of a data link between GTP endpoints, thereby improving the clarity of the logic of the user plane and the clarity of the logic of the control plane.
