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.

Claims

1. A method to automatically track rerouting of data in a data network, the method comprising:

generating, without manual intervention, a table to store current reroute statistics based on the rerouting of the data from one or more logical circuits, when they have failed, to one or more logical failover circuits in the data network, the current reroute statistics including trap data received for the one or more logical circuits in the data network, the trap data including a committed information rate, and each of the one or more logical circuits and each of the one or more logical failover circuits identified by a logical circuit identifier that is renamed until the one or more logical circuits have been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data received for the one or more logical circuits in the data network, wherein 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 being dropped when the committed information rate has been exceeded.

2. The method of claim 1, further comprising generating a billing report including the updated reroute statistics.

3. The method of claim 1, wherein the updated reroute statistics are generated based on restoration of the one or more logical circuits from the failure.

4. The method of claim 1, wherein the trap data comprises the logical circuit identifier for each of the one or more logical circuits and the logical circuit identifier for each of the one or more logical failover circuits.

5. The method of claim 1, wherein the trap data includes a current utilization of each of the one or more logical failover circuits.

6. The method of claim 1, wherein the trap data includes a number of hops taken by each of the one or more logical failover circuits.

7. The method of claim 1, wherein the trap data includes a quality of service parameter for each of the one or more logical failover circuits.

8. The method of claim 1, wherein the quality of service parameter is at least one of an unspecified bit rate, a variable bit rate, or a committed bit rate.

9. An apparatus to automatically track rerouting of data in a data network, the apparatus comprising:

a processor; and

a memory to store machine readable instructions that, when executed by the processor, cause the processor to perform operations comprising;

generating, without manual intervention, a table to store current reroute statistics based on the rerouting of the data from one or more logical circuits, when they are failed, to one or more logical failover circuits in the data network, the current reroute statistics including trap data received for the one or more logical circuits in the data network, the trap data including a committed burst size, and each of the one or more logical circuits and each of the one or more logical failover circuits identified by a logical circuit identifier that is renamed until the one or more logical circuits have been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data received for the one or more logical circuits in the data network, wherein 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 being dropped when the committed burst size has been exceeded.

10. The apparatus of claim 9, wherein the operations further comprise generating a billing report including the updated reroute statistics.

11. The apparatus of claim 9, wherein the updated reroute statistics are generated based on restoration of the one or more logical circuits from the failure.

12. The apparatus of claim 9, wherein the trap data comprises the logical circuit identifier for each of the one or more logical circuits and the logical circuit identifier for each of the one or more logical failover circuits.

13. The apparatus of claim 9, wherein the trap data includes a current utilization of each of the one or more logical failover circuits.

14. The apparatus of claim 9, wherein the trap data includes a number of hops taken by each of the one or more logical failover circuits.

15. The apparatus of claim 9, wherein the trap data includes a quality of service parameter for each of the one or more logical failover circuits.

16. The apparatus of claim 9, wherein the quality of service parameter is at least one of an unspecified bit rate, a variable bit rate, or a committed bit rate.

17. A machine accessible storage device comprising instructions which, when executed, cause a machine to perform a method comprising:

generating, without manual intervention, 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 in a data network, the current reroute statistics including trap data received for the one or more logical circuits in the data network, the trap data including a committed information rate, and each of the one or more logical circuits and each of the one or more logical failover circuits identified by a logical circuit identifier that is renamed until the one or more logical circuits have been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data received for the one or more logical circuits in the data network, wherein 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 being dropped when the committed information rate has been exceeded.

18. The machine accessible storage device of claim 17, wherein the method further comprises generating a billing report including the updated reroute statistics.

19. The machine accessible storage device of claim 17, wherein the updated reroute statistics are generated based on restoration of the one or more logical circuits from the failure.

20. The machine accessible storage device of claim 17, wherein the trap data comprises the logical circuit identifier for each of the one or more logical circuits and the logical circuit identifier for each of the one or more logical failover circuits.
