Communication system, control apparatus, method for controlling same, and program

摘要

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.

1. A control apparatus control method, comprising:
receiving, from at least one of a plurality of nodes each of which includes OAM (Operation Administration and Maintenance) functions, 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; and determining whether to perform route control on the network on a basis of the status change notification and information about a composition of the network, wherein, in the determining whether to perform route control, when a number of paths affected by a failure(s) that has occurred in the network is 1, the path being formed by at least two of the plurality of nodes, it is determined that the route control is not performed.
