Method and apparatus for statistical prediction of access bandwidth on an xDSL network
View Patent ↗Achieved bandwidths for existing subscribers are collected and organized into a statistical bandwidth table utilizing characterizing information, such as the Central Office (CO) that provided the service, the type of xDSL service that was provided, the primary, secondary, and other cable segments over which service was provided, and the subscriber loop length increment. To estimate anticipated bandwidth for a new subscriber, the new subscriber's characterizing information is obtained and used to select one or more entries from the statistical bandwidth table of statistical actual bandwidths achieved by other users that most closely matches the new subscriber's characterizing information. The statistical bandwidth information for the other similarly situated subscribers is used as an estimate bandwidth information for the new subscriber.
1. A method of estimating access bandwidth on a network, the method comprising the steps of:
obtaining bandwidth records for xDSL service provided to existing xDSL subscribers, the bandwidth records contain characterizing information of the existing xDSL subscribers;
creating bandwidth statistics records from bandwidth records of subscribers with similar characterizing information; and
predicting, based on the bandwidth records, an estimated bandwidth for a new xDSL subscriber;
wherein the step of predicting comprises ascertaining characterizing information of the new xDSL subscriber; and estimating the estimated bandwidth from one of the bandwidth statistics records that was created from bandwidth records of subscribers having characterizing information similar to the new xDSL subscriber.
2. The method of claim 1 , wherein the characterizing information comprises at least one of a Network Equipment Identifier (NEI) code, a service type, a primary cable segment, a secondary cable segment, and a subscriber loop length increment.
3. The method of claim 1 , wherein the characterizing information comprising a subscriber loop length increment for the subscriber.
4. The method of claim 1 , wherein the characterizing information comprises a central office indicator, primary cable segment, and secondary cable segment.
5. The method of claim 1 , wherein the bandwidth statistics records contain bandwidth information, the bandwidth information comprising at least one statistic about bandwidths obtained by subscribers with similar characterizing information.
6. The method of claim 5 , wherein said at least one statistic comprises an average bandwidth obtained by said subscribers with similar characterizing information.
7. The method of claim 6 , wherein said average is at least one of an average of individual maximum bandwidths obtained by said subscribers and an average of individual minimum bandwidths obtained by said subscribers.
8. The method of claim 5 , wherein at least a portion of said bandwidth information comprises template data containing default values for likely bandwidths achievable by a subscriber.
9. The method of claim 5 , wherein at least a portion of said bandwidth information comprises system data containing limitations of achievable bandwidths achievable by subscribers.
10. The method of claim 1 , wherein the bandwidth statistics records further comprise identification information.
11. The method of claim 1 , wherein the bandwidth statistics records further contain and reliance information.
12. A method of estimating access bandwidth on a network, the method comprising the steps of:
obtaining bandwidth records for xDSL service provided to existing xDSL subscribers, the bandwidth records contain characterizing information of the existing xDSL subscribers;
creating bandwidth statistics records from bandwidth records of subscribers with similar characterizing information; and
predicting, based on the bandwidth records, an estimated bandwidth for a new xDSL subscriber;
wherein the step of predicting comprises ascertaining characterizing information of the new xDSL subscriber; and estimating the estimated bandwidth by interpolating from bandwidth statistics records that were created from bandwidth records of subscribers having characterizing information similar to the new xDSL subscriber.
13. The method of claim 12 , wherein the characterizing information comprises a central office indicator and primary cable segment.
14. The method of claim 12 , wherein the characterizing information comprises a network equipment identifier and service indicator.
15. A method of estimating access bandwidth on a network, the method comprising the steps of:
obtaining bandwidth records for xDSL service provided to existing xDSL subscribers, the bandwidth records contain characterizing information of the existing xDSL subscribers; and
predicting, based on those bandwidth records, an estimated bandwidth for a new xDSL subscriber;
wherein the characterizing information comprising a subscriber loop length increment for the subscriber; and
wherein the subscriber loop length increment is established by increasing an estimated subscriber loop length to a nearest preset increment value.
16. The method of claim 15 , wherein the estimated bandwidth comprises at least one of an average bandwidth, a maximum bandwidth, and a minimum bandwidth.
