This application provides a data transmission method, a network interface card (NIC) for a data receiving end, an electronic device, and a storage medium. The data transmission method is applied to the NIC of the data receiving end. The NIC writes data to the host memory of the data receiving end via a bus. The data transmission method includes: if the bus bandwidth resources required for the NIC to write the target data to the host memory exceed the bus bandwidth resources available to the NIC, then writing a portion of the target data to the NIC's NIC buffer; the NIC buffer includes a first memory buffer configured for the NIC based on its on-chip memory and a second memory buffer configured for the NIC based on its onboard memory; the data sending end sends the target data to the data receiving end via remote direct memory access; and a portion of the data is written from the NIC buffer to the host memory. The solution of this application can better avoid data packet loss problems when facing sudden traffic surges.

The application provides a kind of transmission layer data packet management method based on fragmentation and reorganization, belong to computer network technical field.Each device includes a server and multiple clients;The process of the first device transmitting messages to the second device is as follows: multiple clients of the first device transmit messages to a sending queue;The server of the first device monitors the sending queue, fragments the message data packet to obtain multiple sub-packets;The server of the second device receives the sub-packets sent by the server of the first device, reassembles the sub-packets, and sends them to a receiving queue;The clients of the second device block and wait for messages from the receiving queue, filter messages by analyzing the identity field in the message header, and process data packets that match their own identity.This method dynamically adjusts the packet size based on the network environment state, avoiding the packet loss or truncation problem caused by MTU limitation on high latency links in the traditional fixed packet mode.

This invention provides a port status adjustment method, apparatus, computer-readable storage medium, and electronic device. The method includes: a first device acquiring a first message from a second device; the first device determining capability information of a first port based on first status information and the actual status of the first port read by the first device; and the first device activating the first port when the capability information matches the first capability information, thereby changing the state of the first port from an abnormal state to a normal state. This invention solves the problem of data loss caused by abnormal port states, thereby improving data interaction capabilities.

This disclosure relates to the field of data processing technology, specifically to data acquisition methods, data display methods, data reporting methods, and apparatus. The data acquisition method applied to a server includes: determining the current network level based on the network conditions between the server and the mobile device; determining the current sampling rate corresponding to the current network level based on a preset correspondence between network levels and sampling rates; sending a sampling rate command to the industrial control computer (ICC) based on the connection with the ICC and the current sampling rate to control the ICC to acquire data based on the current sampling rate; receiving data reported by the ICC; and sending the data to the mobile device for display. This method enables the data acquisition frequency to adapt to the network conditions between the server and the mobile device, thereby effectively avoiding data redundancy or packet loss, ensuring the integrity and efficiency of data transmission, and thus improving the reliability of data display on the mobile device.

This invention discloses a method, apparatus, computer device, and readable storage medium for sending messages in the field of data transmission. The method includes: acquiring a target message and determining the current network transmission rate; if the current network quality is high, detecting whether an important message is being received or sent at the current moment; if an important message is being received or sent at the current moment, detecting whether the target message meets a preset discard condition; if the target message does not meet the preset discard condition, storing the target message in a preset storage space, and after a preset time interval, returning to the step of determining the current network transmission rate until the target message is sent. Based on this, this invention ensures that the sending of any message occurs under conditions of good network quality and without affecting the sending or transmission of important messages, enabling the rational scheduling of resources related to message sending.

The present application relates to the technical field of wireless communication, in particular to a wireless channel measurement time slot scheduling method under multi-wearable device concurrency. The present application periodically acquires the state and distance information of the intelligent wearable device through the base station, dynamically allocates the measurement priority, and determines the total measurement time slot quantity according to the priority. Time slot allocation is adopted, combined with the priority polling mechanism, to allocate non-overlapping AoA / CS measurement time slots for each device, and the starting time and duration are issued through the wireless control channel to guide the device to transmit the measurement signal in the corresponding time slot. The present application solves the wireless channel measurement conflict problem when multiple nodes concurrently access, and through orthogonal allocation and dynamic resource configuration, the balance between high-precision spatial perception and low-power consumption of small-sized wearable devices is considered while reducing the air interface signal collision.
