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.

Claims

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

generating, without manual intervention, a table to store current reroute statistics 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 including trap data corresponding to the logical circuit in the network, the trap data including a committed burst size, the logical circuit identified by a first logical circuit identifier, the logical failover circuit identified by a second logical circuit identifier, the first and second logical circuit identifiers renamed until the logical circuit has been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data corresponding to the logical circuit in the network, the updated reroute statistics being based on a change in a status of the logical circuit corresponding to a frame being dropped when the committed burst size 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 logical circuit from the failure.

4. The method of claim 1, wherein the trap data comprises the first logical circuit identifier for the logical circuit and the second logical circuit identifier for the logical failover circuit.

5. The method of claim 1, wherein the trap data includes a current utilization of the logical failover circuit.

6. The method of claim 1, wherein the trap data includes a number of hops taken by the logical failover circuit.

7. The method of claim 1, wherein the trap data includes a quality of service parameter for the logical failover circuit.

8. The method of claim 7, wherein the quality of service parameter is at least one of an unspecified bit rate, a variable bit rate, and a committed bit rate.

9. An apparatus to automatically track rerouting of data in a 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 a logical circuit that has failed to a logical failover circuit in the network, the current reroute statistics including trap data corresponding to the logical circuit in the network, the trap data including a committed information rate, the logical circuit identified by a first logical circuit identifier, the logical failover circuit identified by a second logical circuit identifier, the first and second logical circuit identifiers renamed until the logical circuit has been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data corresponding to the logical circuit in the network, the updated reroute statistics being based on a change in a status of the logical circuit corresponding to a frame being dropped when the committed information rate 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 logical circuit from the failure.

12. The apparatus of claim 9, wherein the trap data comprises the first logical circuit identifier for the logical failover circuit and the second logical circuit identifier for the logical failover circuit.

13. The apparatus of claim 9, wherein the trap data includes a current utilization of the logical failover circuit.

14. The apparatus of claim 9, wherein the trap data includes a number of hops taken by the logical failover circuit.

15. The apparatus of claim 9, wherein the trap data includes a quality of service parameter for the logical failover circuit.

16. The apparatus of claim 15, wherein the quality of service parameter is at least one of an unspecified bit rate, a variable bit rate, and a committed bit rate.

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

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 including trap data corresponding to the logical circuit in the network, the trap data including a committed burst size, the logical circuit identified by a first logical circuit identifier, the logical failover circuit identified by a second logical circuit identifier, the first and second logical circuit identifiers renamed until the logical circuit has been restored from failure; and

updating the table, without manual intervention, to store updated reroute statistics, the updated reroute statistics including updated trap data corresponding to the logical circuit in the network, the updated reroute statistics being based on a change in a status of the logical circuit corresponding to a frame being dropped when the committed burst size has been exceeded.

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