Abstract

Automatically allocating, modifying, and deleting IP pools for use by network equipment. The network equipment is repeatedly, periodically, or continuously monitored to detect IP pool utilization. If the monitoring indicates an increase in IP pool utilization above a first predetermined threshold, a quantity of required IP pools is forecasted. The forecasted quantity of required IP pools is removed from an inventory of available IP pools and automatically assigned to the network equipment.

Claims

1. A method of automatically allocating, modifying, and deleting IP pools on network equipment, the method comprising:

repeatedly, periodically, or continuously monitoring the network equipment to detect IP pool utilization; and

if the monitoring indicates an increase in the IP pool utilization above a first predetermined threshold, forecasting a quantity of required IP pools, removing the forecasted quantity of required IP pools from an inventory of available IP pools, and automatically assigning the forecasted quantity of required IP pools to the network equipment;

the monitoring including monitoring the network equipment for the IP pool utilization above each of a plurality of predetermined thresholds including at least a major threshold and a critical threshold, wherein the major threshold specifies a first percentage of IP pool utilization on the network equipment and the critical threshold specifies a second percentage of IP pool utilization on the network equipment, and the first percentage is less than the second percentage, wherein IP pool utilization above the major threshold initiates the assigning the forecasted quantity of required IP pools to the network equipment.

2. The method of claim 1 wherein, if the monitoring indicates a decrease in the IP pool utilization below a second predetermined threshold, such that the first and second predetermined thresholds may, but need not, be equal, then forecasting a quantity of IP pools to be removed, removing the forecasted quantity of IP pools from the network equipment, and automatically assigning the removed forecasted quantity of IP pools to the inventory of available IP pools.

3. The method of claim 1 further including allocating the inventory of available IP pools to any of a plurality of allocation levels including at least a LATA allocation level and a network equipment allocation level, wherein the network equipment allocation level corresponds to the network equipment used by a LATA in the LATA allocation level.

4. The method of claim 3 wherein the forecasting indicates that at least one IP pool should be assigned from the LATA allocation level to the network equipment allocation level.

5. The method of claim 1 wherein the first predetermined threshold is the major threshold .

6. The method of claim 1 wherein, if the IP pool utilization exceeds the first predetermined threshold, the method further includes transmitting an indication thereof to one or more users.

7. A computer program product comprising a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method of automatically allocating IP pools to network equipment, the method comprising:

repeatedly, periodically, or continuously monitoring the network equipment to detect IP pool utilization; and

if the monitoring indicates an increase in the IP pool utilization above a first predetermined threshold, forecasting a quantity of required IP pools, removing the forecasted quantity of required IP pools from an inventory of available IP pools, and automatically assigning the forecasted quantity of required IP pools to the network equipment;

the monitoring including monitoring the network equipment for the IP pool utilization above each of a plurality of predetermined thresholds including at least a major threshold and a critical threshold, wherein the major threshold specifies a first percentage of IP pool utilization on the network equipment and the critical threshold specifies a second percentage of IP pool utilization on the network equipment, and the first percentage is less than the second percentage, wherein IP pool utilization above the major threshold initiates the assigning the forecasted quantity of required IP pools to the network equipment.

8. The computer program product of claim 7 further including instructions wherein, if the monitoring indicates a decrease in the IP pool utilization below a second predetermined threshold, such that the first and second predetermined thresholds may, but need not, be equal, then forecasting a quantity of IP pools to be removed, removing the forecasted quantity of IP pools from the network equipment, and automatically assigning the removed forecasted quantity of IP pools to the inventory of available IP pools.

9. The computer program product of claim 7 further including instructions for allocating the inventory of available IP pools to any of a plurality of allocation levels including at least a LATA allocation level and a network equipment allocation level, wherein the network equipment allocation level corresponds to the network equipment used by a LATA in the LATA allocation level.

10. The computer program product of claim 9 wherein the forecasting indicates that at least one IP pool should be assigned from the LATA allocation level to the network equipment allocation level.

11. The computer program product of claim 7 wherein the first predetermined threshold is the major threshold.

12. The computer program product of claim 11 further including instructions wherein, if the IP pool utilization exceeds the first predetermined threshold, transmitting an indication thereof to one or more users.

13. A device for automatically allocating IP pools to network equipment, the device comprising:

a processing mechanism; and

a monitoring mechanism coupled to the processing mechanism;

wherein the monitoring mechanism is capable of repeatedly, periodically, or continuously monitoring the network equipment to detect IP pool utilization; and

if the monitoring indicates an increase in the IP pool utilization above a first predetermined threshold, the processing mechanism forecasts a quantity of required IP pools, removes the forecasted quantity of required IP pools from an inventory of available IP pools, and automatically assigns the removed forecasted quantity of required IP pools to the network equipment;

the monitoring including monitoring the network equipment for the IP pool utilization above each of a plurality of predetermined thresholds including at least a major threshold and a critical threshold, wherein the major threshold specifies a first percentage of IP pool utilization on the network equipment and the critical threshold specifies a second percentage of IP pool utilization on the network equipment, and the first percentage is less than the second percentage, wherein IP pool utilization above the major threshold initiates the assigning the forecasted quantity of required IP pools to the network equipment.

14. The device of claim 13 wherein, if the monitoring mechanism detects a decrease in the IP pool utilization below a second predetermined threshold, such that the first and second predetermined thresholds may, but need not, be equal, then the processing mechanism forecasts a quantity of IP pools to be removed, removes the forecasted quantity of IP pools to be removed from the network equipment, and automatically assigns the removed forecasted quantity of IP pools to the inventory of available IP pools.

15. The device of claim 14 wherein the processing mechanism allocates the inventory of available IP pools to any of a plurality of allocation levels including at least a LATA allocation level and a network equipment allocation level, and wherein the network equipment allocation level corresponds to the network equipment used by a LATA in the LATA allocation level.

16. The device of claim 15 wherein the processing mechanism is capable of assigning at least one IP pool from the LATA allocation level to the network equipment allocation level in response to forecasting the quantity of required IP pools.

17. The device of claim 13 wherein the first predetermined threshold is the major threshold.

18. The device of claim 13 wherein, if the IP pool utilization exceeds the first predetermined threshold, the processing mechanism initiates transmission of an indication thereof to one or more users.
