Abstract: A method and apparatus for operating a smart network interface card are provided. According to an embodiment, the smart network interface card is connected to a baseboard management controller. The method includes: acquiring a smart network interface card detection request, the smart network interface card detection request includes an identifier of a to-be-detected smart network interface card; determining a baseboard management controller that is connected to the to-be-detected smart network interface card as a target baseboard management controller; and logging into an operating system of the to-be-detected smart network interface card through the target baseboard management controller. This embodiment provides a new approach of operating the smart network interface card.

Abstract: A data transmission method includes: establishing, by a server, a connection with a client according to a transmission control protocol (TCP) through a gateway with a synchronous proxy mechanism; acquiring, by the server, sequence number conversion information and converting a first TCP sequence number of a first data packet to be sent to the client according to the sequence number conversion information, so that the first TCP sequence number is matched, by the server, with a first acknowledgment number of the second data packet sent by the client; and sending, by the server, the first data packet, for which the first TCP sequence number has been converted, to the client directly. A server, a gateway, and a computer-readable medium are also disclosed.

Abstract: The present application discloses a method and system for transmitting communication data. A specific implementation of the method comprises: receiving a connection request for transmitting communication data through a remote direct memory access network; determining a transmission type of the communication data according to the connection request; establishing a socket according to the transmission type; transmitting the communication data on the remote direct memory access network by using the socket; and deleting the socket when the transmission of the communication data is completed. This implementation improves the efficiency of transmitting communication data on a remote direct memory access (RDMA) network by a non-RDMA network.

Abstract: A method for measuring a data transmission speed, applied to a server side, is provided. The method includes: updating RTTs within a current sliding period upon receiving an ACK message from a client device; calculating a maximum RTT, a minimum RTT and an average RTT within the current sliding period; obtaining an amount of data in the latest RTT; calculating a minimum speed, a maximum speed and an average speed respectively, according to the amount of data in the latest RTT, and the maximum RTT, the minimum RTT and the average RTT within the current sliding period; calculating speed change gradient information according to the minimum speed, the maximum speed and the average speed; and calculating a speed prediction value according to the speed change gradient information. An apparatus for measuring a data transmission speed, a server-side device and a computer readable medium are provided.
