This invention proposes a message uploading method and a distributed switch stacking system, relating to the field of communication technology. The CPU of the slave device's MPU card determines the destination board based on the load parameters of all LPU cards and SFU cards of the master device and returns the information to the switching chip of the slave device's source LPU.

This allows the message to be processed from the slave device to reach the master device's MPU card CPU with only one CPU-to-CPU forwarding, reducing latency, saving control channel bandwidth and CPU resources, and improving the overall system performance.
