Abstract: A disclosed example method involves identifying a logical failover circuit comprising an alternate communication path in a failover network that is separate from a logical circuit comprising variable communication paths in at least one of a first logical telecommunications network or a second logical telecommunications network and a fixed communication path between the first and second logical telecommunications networks. The failed logical connection is between the first and second logical telecommunications networks. The failover network is reserved to provide failover circuits to communicate data rerouted from failed logical circuits, and the logical failover circuit identified by a second logical circuit identifier. The logical circuit identifier of the logical circuit is renamed to the second logical circuit identifier of the logical failover circuit when a logical connection in the logical circuit has failed. The data is rerouted from the logical circuit to the logical failover circuit without manual intervention.

Abstract: An example method involves, when a first quality of service parameter for a failed logical circuit is equal to or less than a second quality of service parameter for a logical failover circuit, rerouting data from the failed logical circuit to the logical failover circuit without requiring authorization from a customer to communicate the data at the second quality of service parameter. When the second quality of service parameter for the logical failover circuit is a lower level of quality than the first quality of service parameter for the failed logical circuit: a customer is prompted for an authorization to communicate the data via the logical failover circuit at the second quality of service parameter; when the authorization is received, the data is rerouted from the failed logical circuit to the logical failover circuit; and when the authorization is denied, the data is not rerouted to the logical failover circuit.

Abstract: A customer order is received for routing data for a time period. A logical circuit is provisioned for routing the data during the time period. The logical circuit is provisioned through a first LATA, an IEC, and a second LATA. The logical circuit includes first variable communication paths that automatically reroute from a first set of switches to a second set of switches of the first LATA while maintaining the logical circuit, second variable communication paths to route the data through the second LATA, and fixed communication paths to route the data between the first LATA, the second LATA, and the IEC. The second set of switches forms a route associated with the first variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting. The logical circuit is added to a deletion batch for deletion after the time period.

Abstract: An example method involves generating a table to store current reroute statistics based on rerouting of data from one or more logical circuits, when they have failed, to one or more logical failover circuits. The current reroute statistics include trap data received for the one or more logical circuits. The trap data includes a committed information rate. Each of the logical circuits and logical failover circuits is identified by a logical circuit identifier that is renamed until the one or more logical circuits have been restored. The table is updated to store updated reroute statistics that include updated trap data received for the one or more logical circuits. Generating the updated reroute statistics comprises detecting a change in a status of the one or more logical circuits by determining if a frame has been dropped. The frame is dropped when the committed information rate has been exceeded.

Abstract: An example method of rerouting data involves rerouting a logical circuit from a first set of switches to a second set of switches to communicate data between network devices without breaking the logical circuit. The logical circuit comprises variable communication paths. The second set of switches is to form a route associated with the variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting. The example method also involves rerouting the data from the logical circuit to a logical failover circuit in the data network when the logical circuit fails based on a committed information rate having been exceeded. The logical failover circuit comprises an alternative communication path to communicate the data.

Abstract: An example method involves rerouting data from a logical circuit to a logical failover circuit when the logical circuit fails based on an exceeded quality of service parameter. The logical failover circuit is selected based on a committed bit rate, a variable bit rate, or an unspecified bit rate. The example method also involves rerouting data from a first set of switches to a second set of switches in the absence of a failure associated with the logical circuit. The logical circuit comprises variable communication paths, and the second set of switches are to form a route associated with the variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting while maintaining the logical circuit through the second set of switches.
