The invention is directed to managing changes to a configuration of routers connected in a ring network architecture. Embodiments of the invention alleviate risks to services carried over a ring of IP/MPLS routers when configuration changes are made to the ring, such as inserting a router into, or removing a router from, the ring. To that end, embodiments of the invention automate some steps of such a configuration change operation that were previously performed manually, and coordinate those steps with other steps of the operation using a procedure stored as instructions on a computer readable media and executed by a computer system in order to effect and validate a correct sequencing of the steps.
1. A method of managing configuration changes to a configuration of routers connected in a ring network architecture, the configuration changes including provisioning changes to information provisioned on at least one of the routers and connectivity changes to connections between at least two of the routers, the method comprising:
executing automatically, instructions stored on a non-transitory computer-readable medium, the instructions when executed causing a sequence of steps to be performed, the sequence comprising:
determining that the configuration changes include inserting a router;
generating a configuration file for the router to be inserted;
indicating the configuration file is ready to be loaded into the router to be inserted;
determining the router to be inserted is ready for insertion into the ring network architecture;
locking the routers to prevent any alteration to information provisioned thereon that is not related to the configuration changes;
determining ports to be affected by the connectivity changes;
taking the ports out of service;
indicating that the connectivity changes should be initiated;
determining the connectivity changes are complete;
bringing the ports into service; and
unlocking the routers.
