Abstract

Capacity management is described. In an implementation, a method includes executing a module on a computing device to monitor use of a product during a measurement interval to determine a maximum capacity of the product used during the measurement interval and whether a capacity failure point is reached during the measurement interval. A learned capacity limit is set based on the monitoring for determining whether one or more of a plurality of clients, if any, are to receive a list which references at least the monitored product, wherein the learned capacity limit is set such that when the capacity failure point is not reached, the learned capacity limit is set according to the maximum capacity.

Claims

1. A computer-implemented method comprising:

dynamically adjusting via a processor, for each measurement interval of a plurality of measurement intervals, a connectivity value for each of a plurality of access points, the connectivity value based on a relationship of a maximum capacity determined during a current measurement interval to a learned capacity limit determined during a previous measurement interval, the learned capacity limit varying for the plurality of measurement intervals; and

assigning use of a subset of the plurality of access points to one or more of a plurality of clients based on the connectivity value for each access point.

2. The method as recited in claim 1, wherein each said subset is assigned using an access point list for communication to a respective one of the plurality of clients.

3. The method as recited in claim 1, further comprising computing the learned capacity limit for each said access point by:

determining whether a capacity failure point has been reached;

determining a maximum number of the plurality of clients that used the access point;

for each said access point that has not exceeded a respective capacity failure point, setting the learned capacity limit based on the maximum number; and

for each said access point that has exceeded the respective capacity failure point, setting the learned capacity limit based on a previous learned capacity limit which did not result in the access point reaching the respective capacity failure point.

4. The method as recited in claim 1, wherein the connectivity value is configured such that each said access point may be compared, one to another, to describe a relative connectivity experience of the clients with the access point.

5. The method as recited in claim 1, wherein the access point is associated with a communication device.

6. A method comprising:

determining a learned capacity limit of access points during a first measurement interval, the access points associated with respective communication devices; and

during a second measurement interval ensuing after the first measurement interval;

determining a maximum capacity of the access points;

adjusting a connectivity value for each of the access points, the connectivity value based on a relationship of the maximum capacity to the learned capacity limit that varies for measurement intervals; and

assigning use of a subset of the access points to one or more of a plurality of clients based on the connectivity value for each of the access points.

7. The method as described in claim 6, wherein the access points are selected from a group consisting of:

one or more telephone numbers,

a wireless access point, and

a data distribution point.

8. The method as described in claim 6, wherein:

the access points are configured as access numbers for obtaining Internet access; and

each access point includes a plurality of references to the access numbers.

9. The method as described in claim 6, wherein:

the maximum capacity is configured as a capacity failure rate threshold; and

at least one said access point has a capacity failure rate threshold which is different from another capacity failure rate threshold for another said access point.

10. The method as described in claim 6, wherein the learned capacity limit exceeds a contracted capacity for the monitored product.

11. The method as described in claim 6, wherein the maximum capacity is a capacity failure rate threshold.

12. One or more computer-readable media storing computer-executable instructions that, when executed on one or more processors, causes the one or more processors to perform acts comprising:

dynamically adjusting a connectivity value for each of a plurality of access points based on a relationship of a maximum capacity used to a learned capacity limit; and

assigning use of a subset of the plurality of access points, respectively, to one or more of a plurality of clients based on the connectivity value for each said access point.

13. The one or more computer-readable media as recited in claim 12, wherein the dynamically adjusting is performed such that the assigning of at least one said access point is reduced when the relationship indicates that the maximum capacity used for the at least one said product is approaching the learned capacity limit.

14. The one or more computer-readable media as recited in claim 12, wherein the plurality of access points includes at least one of:

a telephone number,

a wireless access point, or

a data distribution point.

15. The one or more computer-readable media as recited in claim 12, wherein

the access points are configured access numbers for obtaining Internet access;

and

each access point includes a plurality of references to the access numbers.

16. The one or more computer-readable media as recited in claim 12, further comprising determining a maximum capacity of each of the plurality of access points being utilized during a plurality of measurement intervals.
