Abstract

Methods and apparatus to manage a bonded digital subscriber line (DSL) service are disclosed. A disclosed example method comprises collecting data representative of bandwidth usage for two or more applications serviced by a bonded set of subscriber lines; analyzing historical activity of the two or more applications based on the collected bandwidth usage data; and selecting a first digital subscriber line (DSL) line profile for a first wire pair in the set of subscriber lines, the set of subscriber lines forming a single DSL communication link.

Claims

1. A method comprising:

collecting data representative of bandwidth usage for two or more applications serviced by a bonded set of subscriber lines;

analyzing historical activity of the two or more applications based on the collected bandwidth usage data; and

selecting a first digital subscriber line (DSL) line profile for a first wire pair in the set of subscriber lines, the set of subscriber lines forming a single DSL communication link.

2. A method as defined in claim 1, further comprising selecting a second DSL line profile for a second wire pair in the set of subscriber lines based on the historical activity.

3. A method as defined in claim 2, wherein the first DSL line profile is different from the second DSL line profile.

4. A method as defined in claim 2, wherein the first DSL line profile is adapted to a first service quality characteristic of a first application, and the second DSL line profile is adapted to a second service quality characteristic of a second application.

5. A method as defined in claim 1, wherein the first DSL line profile is selected based on a performance difference between the first pair and a second wire pair in the set of subscriber lines.

6. A method as defined in claim 1, wherein the first DSL line profile is selected to secure a service quality characteristic for at least one of the applications.

7. A method as defined in claim 1, wherein the bandwidth usage data is collected via a customer-premises DSL modem.

8. A method as defined in claim 1, wherein the collected data comprises an Internet protocol address for each respective one of the two or more applications, and a bandwidth usage value for each respective one of the two or more applications.

9. A method as defined in claim 1, wherein the set of subscriber lines are electrically coupled to a single customer premises.

11. A method as defined in claim 1, further comprising disabling a first application to a customer premises to secure a service quality characteristic of a second application.

10. (canceled)

12. An apparatus comprising:

a data collection server to collect bandwidth usage data for two or more applications delivered by a bonded set of subscriber lines;

a profile selector to select a first digital subscriber line (DSL) line profile for a first wire pair in the bonded set and a second DSL line profile for a second wire pair in the bonded set based on the collected bandwidth usage data, the bonded set forming a single DSL communication link.

13. An apparatus as defined in claim 12, wherein the profile selector is to analyze historical activity of the two or more applications based on the bandwidth usage data, and to select the first and second DSL line profiles based on the historical activity.

15. An apparatus as defined in claim 12, further comprising an error tracker to detect when a number of errors per unit of time associated with the first wire pair exceeds a threshold.

16. An apparatus as defined in claim 15, wherein the data collection server collects the bandwidth usage data when the number of errors per unit time exceeds the threshold.

17. An apparatus as defined in claim 12, further comprising an error tracker to detect when an increase in a number of errors associated with the first wire pair exceeds a threshold.

18. An apparatus as defined in claim 12, further comprising a profile database, wherein the profile selector selects the first and second DSL line profiles from the profile database.

24. An apparatus as defined in claim 12, wherein the profile selector is to select the first and second DSL line profiles to tradeoff a first service quality characteristic of a first application against a second service quality characteristic of a second application.

25. An apparatus as defined in claim 12, wherein the profile selector is to disable a first application to secure a service quality characteristic of a second application.

26. An article of manufacture storing machine readable instructions which, when executed, cause a machine to:

collect data representative of bandwidth usage for two or more applications serviced by a bonded set of subscriber lines;

analyze historical activity of the two or more applications based on the collected bandwidth usage data; and

select a first digital subscriber line (DSL) line profile for a first wire pair in the set of subscriber lines, the set of subscriber lines forming a single DSL communication link.

27. An article of manufacture as defined in claim 26, wherein the machine readable instructions, when executed, cause the machine to select a second DSL line profile for a second wire pair in the set of subscriber lines based on the historical activity, wherein the first DSL line profile is adapted to a first service quality characteristic of a first application, and the second DSL line profile is adapted to a second service quality characteristic of a second application.

28. An apparatus comprising:

a first digital subscriber line (DSL) modem to couple the apparatus to a DSL access multiplexer (DSLAM) via a first subscriber line;

a second DSL modem to couple the apparatus to the DSLAM via a second subscriber line, the first subscriber line bonded to the second subscriber line to form a single DSL communication link; and

an application layer logger to receive user data directed to a host, to determine whether the user data directed to the host is blocked, and to update a bandwidth usage associated with the host when the user data is not blocked.

29. An apparatus as defined in claim 28, wherein the first DSL modem is to receive a DSL line profile via the DSLAM, the DSL line profile selected based on the bandwidth usage.

30. An apparatus as defined in claim 28, further comprising a host table to store the updated bandwidth usage and an Internet protocol address associated with the host.

31. An apparatus as defined in claim 28, wherein the apparatus comprises a residential gateway.

32. An apparatus as defined in claim 28, wherein the apparatus comprises a network interface device.
