Abstract
Re-routing interactions are predicted for a communications network including a plurality of network elements. A respective device state image is constructed for each of the plurality of network elements, with each of the device state images including a failover setting of a respective one of the network elements. The device state images are transmitted to a network simulator. The performance of the communications network is simulated in response to the device state images. A prospective network element failover of a predetermined one of the network elements is transmitted to the network simulator. A performance of the communications network is simulated in response to the device state images modified by the prospective network element failover. It is then detected whether an acceptable performance is maintained in view of the prospective network element failover in order to identify whether is will be permissible to perform a maintenance action on the network element which makes it unavailable to the network.
