Methods and systems for automatically rerouting logical circuit data from a logical circuit failure to a dedicated backup circuit in a data network

A system to reroute data, comprising:

• a processor;
• and
• a memory storing machine readable instructions that cause the processor to perform a method comprising:
• rerouting a logical circuit from a first set of switches to a second set of switches to communicate data between network devices while maintaining the logical circuit, the logical circuit comprising variable communication paths, and the second set of switches 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 of the variable communication paths;
• 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;
• and
• rerouting the data from the logical circuit to a logical failover circuit in the data network in response to detecting the failure of the logical circuit, wherein the logical failover circuit comprises an alternative communication path to communicate the data.

A tangible machine accessible storage device or storage disc comprising instructions that cause a machine to perform a method comprising:

• rerouting a logical circuit from a first set of switches to a second set of switches to communicate data between network devices in an absence of a failure of the logical circuit, the logical circuit comprising variable communication paths, and the second set of switches to form a route associated with the variable communication paths that is not predefined and that is dynamically defined at a time at which the variable communication paths are automatically rerouted while maintaining the logical circuit through the second set of switches;
• 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;
• and
• rerouting the data from the logical circuit to a logical failover circuit in the data network in response to detecting the failure of the logical circuit, wherein the logical failover circuit comprises an alternative communication path to communicate the data.
