AI Technical Summary
Technical Problem
In multi-node servers, data parsing corruption can occur when the CPLD or LAN SW is reset or the firmware is upgraded.
Method used
During the communication period, the logic device acquires and parses the data packets of the local area network switch and saves the parsed data to the register. If a reset or firmware upgrade event is detected before the target data packet is parsed, the register is cleared and the communication cycle is redefined until the data is completely parsed before being sent to the node management controller.
Benefits of technology
This avoids data parsing chaos, ensures the normal operation of control logic, improves the stability and continuity of communication, and avoids data loss and errors caused by reset or firmware upgrade.

Abstract
The application discloses a data communication method and an electronic device, which are applied to a target centralized management controller constructed based on a logic device in a multi-node server, and relate to the technical field of data communication, and the method comprises the following steps: obtaining and analyzing a target data packet of a local area network switch through the logic device in a communication time period, and saving the target data packet into a register of the logic device; if it is monitored that the logic device or the local area network switch is reset or firmware is upgraded before the analysis is completed, the register is cleared, the target data packet is re-obtained and analyzed, and until the target data packet is completely analyzed and saved into the register, the analyzed data is sent to a node management controller to adjust the network port state of the corresponding node. In the communication time period, data is obtained and analyzed through the logic device, and the register is cleared when the logic device or the local area network switch is reset or firmware is upgraded, so that the control logic can be ensured to normally operate while the error data is emptied, and data analysis confusion is avoided.
