摘要： Embodiments provide an SDN, an SDN configuration method, an SDN-based data transmission method, and a network controller. A data packet combination function and a data packet split function are separately configured on nodes in the SDN. Therefore, when data packets of a first service are received, multiple small data packets of the first service may be combined into one large data packet. In comparison with transmission of the multiple small data packets, transmission efficiency of the SDN can be improved by transmitting the combined data packet.

摘要： The present disclosure provide a data transmission method, including: receiving, by a central processing node, downlink user data from a first gateway GW; sending, by the central processing node, the downlink user data to a corresponding base station; and when it is determined that an interface between the central processing node and the first GW is congested, sending, by the central processing node, a first bearer switching request message to the first GW, where the first bearer switching request message is used to instruct the first GW to bypass the central processing node when transmitting data. In the embodiments of the present invention, when determining that an interface between a central processing node and a first GW is congested, the central processing node sends a first bearer switching request message to the first GW, so that the first GW transmits downlink user data with the central processing node bypassed.

摘要： A method for obtaining feedback delay includes: obtaining a target time elapsed in a process from when a remote radio end receives uplink data sent from a user end to when the remote radio end sends out feedback information responsive to the uplink data to the user end, wherein the feedback information responsive to the uplink data is fed back by a processing node to the remote radio end; calculating a feedback delay by adding the target time and an air interface transmission propagation delay, wherein the air interface transmission propagation delay is a transmission time of the uplink data from the user end to the remote radio end; and configuring, by the processing node, an uplink hybrid automatic repeat request (HARQ) ACK/NACK feedback interval to be the feedback delay.

摘要： Example response information sending and receiving methods and apparatus are described. One example sending method includes receiving first indication information by a first communications device from a network device, where the first indication information is used to indicate a first resource for transmitting first data. The first communications device sends the first data to a second communications device on the first resource. The first communications device receives second indication information from the network device, where the second indication information is used to indicate a second resource for transmitting response information of the first data. The second source and the first resource do not include a same resource. The first communications device receives the response information of the first data from the second communications device on the second resource.
