and establishing a real loop model, wherein the real loop models according to the hierarchical relation of the device, the board card, the port and the optical fiber number, and the switch models according to the hierarchy.

Therefore, all normal virtual link physical paths are traversed in sequence, so that non-fault points in the fault node set can be eliminated, the fault range is reduced, and fault location is realized.
