If the transmission quality of at least one link in the links does not meet the preset condition, such as low signal strength and high error rate, it is indicated that the transmission quality of the at least one link is low and is not beneficial to transmission, therefore, the link whose transmission quality does not meet the preset condition can be eliminated from the links, then the current bandwidth utilization rate of the remaining links is calculated, and further, if the current bandwidth utilization rate exceeds the bandwidth threshold, a bandwidth alarm is sent out, that is, the user is timely prompted that the bandwidth is insufficient and is currently overloaded for transmission, and meanwhile, the data transmitted in the links is switched to the protection link for transmission, that is, protection switching is performed, so as to further improve the stability of data transmission.
