Abstract

A method and system that allow subscribers to a cable Internet data service to use a Web browser and access to the Internet via their cable Internet data service to dynamically change their service level by communicating with the cable modem manager that manages their cable modem. An alternate method and system allow a content provider that has been contacted by a subscriber to dynamically implement new “on-demand” services flows for the subscriber. With both arrangements, the subscriber can begin employing the new service flows without reinitializing their cable modem or otherwise having their data service disrupted.

Claims

1. A management information base for defining a DSx protocol request, comprising:

a plurality of template tables, each of the template tables containing at least one characteristic field for storing a DSx protocol request characteristic; and

a plurality of request tables, at least one of the request tables

corresponding to a particular type of DSx protocol request and

having one or more identifier fields for containing an identifier identifying a field in one of the plurality of template tables containing a DSx protocol request characteristic, the one or more identifier fields corresponding to a DSx request such that characteristics contained in the fields indentified in the one or more identifier fields define the DSx request.

2. The management information base recited in claim 1, wherein the template tables include a quality-of-service parameter table for containing quality of service parameters, a packet classifier table for containing packet classifiers, and a payload header suppression rules table for containing payload header suppression rules.

3. The management information base recited in claim 1, wherein the plurality of request tables includes a dynamic service add request table, a dynamic service change request table, and a dynamic service delete request table.

4. The management information base recited in claim 1, further including an allocator for allocating values employed in the request tables for identifying a specific DSx request.

5. The management information base recited in claim 1, further including a response table for storing response information provided in response to a DSx request defined by the management information base.

6. The management information base recited in claim 1, wherein each of the request tables includes a field for storing a status of the DSx request.

10. The management information base recited in claim 1, further including an allocator for allocating values employed in the request tables for identifying a specific DSx request.

7. A data structure, comprising:

a plurality of template tables, each of the template tables containing at least one characteristic field storing a type of DSx protocol request characteristic; and

a plurality of request tables, at least one of the request tables

corresponding to a particular type of DSx protocol request and

having one or more identifier fields containing an identifier identifying a characteristic field in one of the plurality of template tables containing a DSx protocol request characteristic, the one or more identifier fields corresponding to a DSx request such that characteristics contained in the fields indentified in the one or more identifier fields define the DSx request.

8. The data structure recited in claim 7, wherein the template tables include a quality-of-service parameter table for containing quality of service parameters, a packet classifier table for containing packet classifiers, and a payload header suppression rules table for containing payload header suppression rules.

9. The data structure recited in claim 7, wherein the plurality of request tables includes a dynamic service add request table, a dynamic service change request table, and a dynamic service delete request table.

11. The data structure recited in claim 7, further including a response table storing response information provided in response to a DSx request defined by the management information base.

12. The data structure recited in claim 7, wherein each of the request tables includes a field storing a status of the DSx request.

14. The method of claim 13, wherein the template tables include a quality of service parameter set table, a packet classifier table, and a payload header suppression rules table.

15. The method of claim 13, wherein the request table corresponds to one of a dynamic service add request, a dynamic service change request, and a dynamic service delete request.

16. The method of claim 13, further including receiving response values in response to the DSx request prepared by the DSx agent.

17. The method of claim 13, further including assigning a DSx request identifier value for all of the identifier fields in a request table entry associated with the DSx request.

19. The method of claim 18, wherein the designated characteristics for a new service flow is provided by a cable modem manager managing the cable modem.

20. The method of claim 18, wherein the subscriber provides the designated characteristics for a new service flow by referencing service flow information contained in a cable modem manager managing the cable modem.

21. The method of claim 18, wherein the designated characteristics for a new service flow for are provided by a content server providing content to the subscriber.

22. The method of claim 18, wherein the database is a cable modem manager.

23. The method of claim 18, wherein the request from the subscriber requests a temporary change in service flow.

24. The method of claim 18, wherein the request from the subscriber requests a permanent change in service flow.

26. The system of claim 25, wherein the instruction designating characteristics for a new service flow is provided by the subscriber

27. The system of claim 26, wherein the subscriber provides the instruction by referencing service flow information contained a cable modem manager.

28. The system of claim 25, wherein the instruction designating characteristics for a new service flow is provided by a content server providing content to the subscriber.

29. The system of claim 25, wherein the request from the subscriber requests a temporary change in service flow.

30. The system of claim 25, wherein the request from the subscriber requests a permanent change in service flow.

13. A method of constructing a DSx protocol request, comprising:

receiving one or more DSx request messages, each DSx request message setting forth a characteristic to be included in a DSx request;

for each DSx message,

assigning the characteristic to a characteristic field in one of a plurality of template tables; and

assigning an identifier to an identifier in a request table entry identifying the field in the template table for the characteristic; and

providing each characteristic in a field identified by an identifier in the request table for a DSx request to a DSx manager to prepare a DSx request.

18. A method of dynamically changing a service level of a subscriber to a communications network service, comprising:

receiving a request from a subscriber to dynamically change a service flow for the service;

contacting a database to obtain an address for a cable modem and cable modem termination system associated with the subscriber; and

providing the characteristics for the new service flow and the address for the cable modem to the cable modem termination system to execute the new service flow.

25. A system for allowing a subscriber to request a dynamic change in a service level of a communications network service, comprising:

a service manager for receiving a request from a subscriber to dynamically change a service flow and an instruction designating characteristics for a new service flow;

a cable modem termination system for implementing a new service flow having the characteristics set forth in the instruction;

a cable modem manager for providing the service manager with an address for a cable modem associated with the subscriber and an address of the cable modem termination system in response to the request;

the service manager forwarding the characteristics set forth in the instruction to the cable modem termination system upon receiving the address for the cable modem and the address for the cable modem termination system from the cable modem manager.
