A method for processing channel failure in automatically switched optical network, upon generating channel alarm, the first node of traffic determine whether the alarm is caused by channel failure according to the alarm information or alarm message; if so, continues to position the channel failure within and out of the network by the first node and end node of traffic, by using the combination of local detection and message announcement; if it is the failure within the network, then accurately positions and clears the channel failure in the way of rerouting. Processing the channel failure by using this method, the quantity of exchanging information is small, and thus enables accurately and timely position the particular location of the channel failure within the network, thereby achieves quick failure clearance, reduces the loss of traffic as best, while at the same time affects the working ability of device and network performance much slightly. . |
