摘要： A primary optical path in an optical network is established between first and second edge nodes of the optical network for communication between the first edge node and a primary customer network site coupled to the second edge node. A backup optical path through the optical network from the first edge node to a third edge node of the optical network other than the second edge node is determined for communication between the first edge node and a backup customer network site coupled to the third edge node of the optical network. The backup customer network site is designated to back up the primary customer network site. Communications are forwarded on the primary optical path from the first edge node toward the primary customer network site via the second edge node. Upon detection of a degradation or failure of the primary customer network site, communications are forwarded on the backup optical path from the first edge node toward the backup customer network site via the third edge node.
