Abstract:
1. A method to centrally generate a changeover sequence to reconfigure the routings of connections of a connection-oriented network from an existing configuration to a desired configuration, the method including: determining the existing configuration and the desired configuration for the routings of connections of the connection-oriented network, the determination of the desired configuration being made prior to commanding any changes to the existing configuration of the network; centrally generating a sequence of configuration specifications for the connection-oriented network so that the last configuration specification of the sequence specifies the desired configuration, the sequence of configuration specifications having at least one intermediate configuration between the existing configuration and the desired configuration, the last configuration specification of the sequence being generated prior to commanding any changes to the existing configuration of the network; commanding at least one network element in accordance with each configuration specification of the sequence; and centrally receiving an acknowledgement of successful completion of an implementation of a configuration specification of the sequence by the network element prior to commanding the network element with a subsequent configuration specification of the sequence, the commanding a subsequent configuration specification of the sequence including commanding at least one network element of the connection-oriented network to execute a specific configuration specification.
