***Wrap and steering***
When failures like fiber cut occur, the system adopts two self-healing modes, namely wrap and steering.

As shown in Figure 3-2, when the wrap mode is used, the traffic that is previously on the outer ring from A to B is sent to the node adjacent to the failed line, then loop back to the inner ring for transmission. When the steering mode is used, the traffic that is previously on the outer ring is directly redirected to the inner ring for transmission.
