摘要：本发明公开了一种控制方法、装置和系统。本发明实施例采用在发送给RNDIS设备的网络数据包中封装控制命令，然后将封装后的网络数据包发送给RNDIS设备，以对RNDIS设备进行控制。由于在现有的网络架构中，用户端设备本来就可以直接将网络数据包发送给RNDIS设备，所以采用该方案无需额外增加新的控制接口就可以向RNDIS设备传输控制命令，相对于现有技术中需要额外增加新的控制接口和安装驱动程序的方案而言，降低了使用的复杂度，而且对RNDIS设备没有特殊的要求，具有普遍的适用性，实现较为简单。

摘要： A data transmission method in software-defined networking (SDN) environment using transmission control protocol (TCP). An application server sends a transmission resource allocation request to a controller. The request carries an address of a sending device and an address of a receiving device. The controller determines a first transmission path and a second transmission path between the sending device and the receiving device according to the request. The first transmission path is used by the sending device to transmit data to the receiving device, and the second transmission path is used by the receiving device to transmit an acknowledgment to the sending device. The controller sends a transmission resource allocation response to the application server. The application server determines, according to the response, an initial value of a transmit window for transmitting data. The sending device transmits the data to the receiving device according to the transmit window.

摘要： Embodiments of the present invention provide a data transmission method, apparatus, and system, applied to an SDN network, so as to implement configuration of a path for TCP data transmission, and set a size of a transmit window according to parameters of the path. The method includes: receiving, by a controller, a TCP transmission resource allocation request from an application server; determining a first transmission path and a second transmission path according to the TCP transmission resource allocation request, where the first transmission path is used by a sending device to transmit data to a receiving device, and the second transmission path is used by the receiving device to transmit a TCP acknowledgment to the sending device; and sending a TCP transmission resource allocation response message to the application server, where the TCP transmission resource allocation response message includes bandwidth information of the first transmission path and a TCP round-trip transmission delay. A transmit window is calculated according to bandwidth information of a first transmission path and a TCP round-trip transmission delay, so that data is transmitted with a maximum throughput, and halved oscillation of a sliding window caused by network detection is avoided.

摘要： The present invention discloses a control method, an apparatus, and a system. In the embodiments of the present invention, a control command is encapsulated into a network data packet to be sent to a remote network driver interface specification (RNDIS) device, and the encapsulated network data packet is sent to the RNDIS device to control the RNDIS device. In the conventional network architecture, a user device can directly send a network data packet to an RNDIS device. Therefore, with this solution, a control command can be transmitted to the RNDIS device without adding a new control interface. Compared with the solution that requires adding a new interface and installing an additional driver program in the prior art, this solution reduces application complexity and has no special requirement for the RNDIS device, which is commonly applicable and easy to implement.

摘要： A method of transporting data from a sending node to a destination node includes processing select data (902) to form a stream of data packets (904) at a sending node (800) for transport to a destination node (812). The stream including a group (908) of data packets (918). The group carrying a segment (910) of the select data. The segment including fragments (912) of the select data. The segment associated with a segment identifier. Each fragment associated with a fragment identifier. Each group data packet carries a corresponding fragment, a fragment identification value (916), a segment identification value (914), and a verification check value (920). A last group data packet (922) carries an end of segment value (924). The method includes transmitting the group of data packets to the destination node, with the last data packet transmitted last such that the transmitting continues without waiting for a segment response message from the destination node between transmissions of the group of data packets.
