- Abstract
- In a network in which a plurality of protection paths have been formed for one working path between a first node and a second node, each node determines preference levels corresponding to an order to be preferentially used when performing protection switching on the plurality of protection paths. Next, each node exchanges pieces of information about the preference levels determined for the plurality of protection paths.
