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 involves assigning a first logical circuit identifier to a logical failover circuit prior to a failure of a dedicated logical circuit. The dedicated logical circuit includes first variable communication paths to route data through a first local access and transport area (LATA), second variable communication paths to route the data through a second LATA, and fixed communication paths to route the data between the first LATA, the second LATA, and an inter-exchange carrier. The failure of the dedicated logical circuit is identified based on status information pertinent to the dedicated logical circuit. The logical failover circuit includes an alternate communication path for communicating the data. When the first logical circuit identifier does not match the second logical circuit identifier, the second logical circuit identifier is renamed to match the first logical circuit identifier. The data is rerouted to the logical failover circuit without manual intervention.

Abstract: An example method involves generating, with a network management module, a data structure to store current reroute statistics based on rerouting of data from a logical circuit that has failed to a logical failover circuit in a network. The current reroute statistics include trap data corresponding to the logical circuit. The trap data includes a committed burst size. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. The table is updated with the network management module to store updated reroute statistics. The updated reroute statistics include updated trap data corresponding to the logical circuit. The updated reroute statistics are based on a change in status of the logical circuit resulting from the committed burst size having been exceeded.

Abstract: A customer order is received for routing data for a time period, and provisioning a logical circuit 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 form 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, and disconnected at the end of the time period.

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 providing, with a network management module of a network management system, current reroute statistics in a data structure based on the rerouting of the data from a logical circuit that has failed to a logical failover circuit in the network. The current reroute statistics include a committed information rate corresponding to the logical circuit in the network. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. Updated reroute statistics are provided, with the network management module, based on a change in a status of the logical circuit resulting from the committed information rate having been exceeded.
