Abstract: The present invention relates to a detection method for a multi-access edge computing architecture. The multi-access edge computing architecture uses the technology of bump-in-the-wire (BITW) to be deployed between the user device and the core network. The multi-access edge computing architecture includes a baseboard management controller, an edge computing service module, a central processing unit module, and a switching module. When any function in the multi-access edge computing architecture fails, the detection method of the present invention is used to actively detect and directly connect the base station to the core network. When the function is restored, the detection method of the present invention can actively restore the original path of the base station and the core network connected to the multi-access edge computing architecture to achieve seamless debugging and other purposes.
