The routine maintenance for an ASON network involves service monitoring and resource monitoring. Service monitoring enables maintenance personnel to determine the affected scope at the earliest time when a fault occurs on the network. Then, the maintenance personnel can determine the rectification measures based on the characteristics of the fault and the current service status. In this manner, the maintenance personnel can determine the health status of the services promptly and minimize the impact on the services. Resource monitoring enables maintenance personnel to eliminate potential faults on the network in real time and thus eliminate the severe potential risks in routine maintenance. Rectifying the resource anomalies in real time can help to improve the network resources utilization rate, promote the service survivability, discover the bottleneck of the network resources in advance, take capacity expansion measures promptly, and ensure healthy operation of the network all the time.
