Abstract: Implementations of this disclosure provide data transmission operations and network interface controllers. An example method performed by a first RDMA network interface controller includes obtaining m data packets from a host memory of a first host; sending the m data packets to a second RDMA network interface controller of a second host; backing up the m data packets to a network interface controller memory integrated into the first RDMA network interface controller; determining that the second RDMA network interface controller does not receive n data packets of the m data packets; and in response, obtaining the n data packets from the m data packets that have been backed up to the network interface controller memory integrated into the first RDMA network interface controller, and retransmitting the n data packets to the second RDMA network interface controller.

Abstract: A Remote Direct Memory Access (RDMA) based data transmission method is disclosed. In this method, an RDMA network interface card is used to encrypt data to improve the security of data transmission. In addition, the data encryption and decryption operation is implemented inside the RDMA network interface card and is transparent to software, thereby ensuring security without adversely affecting performance of an application program.

Abstract: A Remote Direct Memory Access (RDMA) data sending method is disclosed. The method is applicable to a sending end, with a data-transmission RDMA device disposed thereon. The method includes: the data-transmission RDMA device acquiring raw data; the data-transmission RDMA device compressing the raw data by using a preset compression method to obtain compressed data; and the data-transmission RDMA device encapsulating the compressed data into a data packet, and transmitting the data packet to a receiving end. The data packet may include a method tag corresponding to the preset compression method. In this method, the compression and transmission of the raw data are conducted by the data-transmission RDMA device on the hardware level.
