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. The switching chip of the slave device's source LPU card adds a private encapsulation to the message to be processed using the destination board's information and a preset identifier, and determines the outgoing port according to the forwarding path table pre-issued by the slave device's MPU card CPU. The message is then forwarded across cards via the data channel until it reaches the switching chip of the destination board. The switching chip of the destination board decapsulates the encapsulated protocol message to recover the message to be processed, and the destination board's CPU uploads it to the master device's MPU card CPU. 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.
