Abstract
A method for resuming topology of a single loop network and a network switch system are provided. The network switch system includes one or more first network switches each having a first port and a second port and a second network switch having a third port and a fourth port. When the first port of one of the first network switches is abnormal, a recovery control frame is transmitted through the second port. The second network switch sets the third port in a disabled state to an enabled state. When the abnormal port is resumed, the first network switch transmits a block control frame through the second port. The second network switch sets the third port in the enabled state to the disabled state and transmits a forward control frame through the fourth port. The first network switch sets the first port in the disabled state to the enabled state.
