Abstract
A communication system includes: a plurality of nodes each of which is configured to include OAM (Operation Administration and Maintenance) functions; and a control apparatus configured to control the plurality of nodes. Each of the nodes transmits a status change notification including information about a port(s) affected by a failure(s) that has occurred in a network composed by the plurality of nodes to the control apparatus. The control apparatus determines whether to perform route control on the network on the basis of the status change notification and information about a composition of the network.
