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.

Abstract: A customer order is received for routing data for a time period. A 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 disconnected following the end of the time period.

Abstract: An example method involves generating, without manual intervention, a table 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, without manual intervention, 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 corresponding to a dropped frame when the committed burst size has been exceeded.

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 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 includes 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. The example method also involves detecting a failure of the logical circuit based on at least one of a committed information rate or a committed burst size having been exceeded. In addition, the data is rerouted from the logical circuit to a logical failover circuit in the data network in response to detecting the failure of the logical circuit. The logical failover circuit includes 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.

Abstract: An example involves selecting a logical failover circuit comprising an alternate communication path for communicating data upon a failure of a dedicated logical circuit connecting a host device to a remote device. When a first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit: the second logical circuit identifier of the logical failover circuit is renamed to identify the logical failover circuit using the first logical circuit identifier when the logical failover circuit is a dedicated logical failover circuit used to communicate only when the dedicated logical circuit fails, and the dedicated logical circuit is renamed to identify the dedicated logical circuit using the second logical circuit identifier when the logical failover circuit is used to communicate regardless of the failure of the dedicated logical circuit. The data is rerouted to the logical failover circuit without manual intervention.
