Abstract
In a network having working and protection paths, extra traffic is put on the protection paths when they are not being used by working traffic. In the event of a fault in a working path, the working traffic is switched to a respective protection path using a span switch operation. The extra traffic is displaced, but at least some of it is protected by switching it to an alternative path using a ring switch operation.
