Abstract

For on-demand Quality of Service (QoS) transmission of packets, in a data transmission network between users, service providers and network providers, a database links service providers and different paths of different QoS levels through the network, for contents delivery based upon a fee schedule related to QoS path usage duration and QoS path usage levels. In response to a user request, a requested QoS path is set-up on demand for delivery of contents over the network from the service provider. When the set-up is successful, payment from the service provider to the network provider is based upon the fee schedule. In response to a delivery failure over the set-up path, responsibility for the failure is determined and payment responsibility is adjusted according to the determined responsibility. Compensation is to the service provider when the network provider is responsible for a failure of delivery event. In response to path set-up failure, the user is prompted for a request selection of the same content at one of a lower quality or a retry of the previous quality.

Claims

1. A method performed while communicating by a data transmission network between a user, a service provider and a network provider, said method being machine performed by the network provider and comprising the steps of:

managing a database with links between each of different service providers and a plurality of different path QoS levels through the network, for contents delivery based upon a fee schedule related to usage of the different QoS levels;

receiving a request for a QoS path from the service provider;

in response to the received request for a QoS path, attempting to set-up the requested QoS path between the service provider and the user;

when the set-up is successful, forwarding a content stream from the service provider to the user over the requested QoS path; and

when the set-up is successful, receiving payment from the service provider for the QoS path usage.

2. The method of claim 1, wherein:

said managing and receiving includes relating the fee schedule to QoS path usage duration and QoS path usage levels.

3. The method of claim 1, further comprising:

as a part of said step of attempting to set-up, checking network resource availability as to whether the requested QoS path is available to be assigned to use by the service provider, attempting to set-up the QoS path, and notifying the requester whether or not the path set-up is successful.

4. The method of claim 3, further comprising:

providing information to the service provider as to responsibility for a failure of content delivery over the QoS path; and

providing compensation to the service provider when the network provider is responsible for a failure of delivery event.

5. The method of claim 1, further comprising:

as a part of said step of attempting to set-up, checking network resource availability as to whether the requested QoS path is available to be assigned to use by the service provider, providing information to the service provider on currently available paths, and requesting the service provider to commit to one of the QoS paths.

6. The method of claim 5, further comprising:

providing information to the service provider as to responsibility for a failure of content delivery over the QoS path; and

providing compensation to the service provider when the network provider is responsible for the failure of delivery event.

7. The method of claim 1, further comprising:

providing information to the service provider as to responsibility for a failure of content delivery over the QoS path.

8. The method of claim 7, further comprising:

providing compensation to the service provider when the network provider is responsible for the failure of delivery event.

9. The method of claim 8, further comprising:

said managing includes relating fees of the fee schedule to QoS path usage duration and QoS path usage levels.

10. A method performed while communicating by a data transmission network between a user, a service provider and a network provider, said method being machine performed by the service provider and comprising the steps of:

contracting with the network provider to provide a plurality of different QoS levels of contents delivery for a fee schedule related to usage of the different QoS levels;

receiving a content selection related request from the user;

correlating the content selection related request and one of the QoS levels;

in response to the received content selection related request, requesting the network provider to set-up a QoS path between the service provider and the user on an end-to-end basis with a guarantee of the correlated one of the QoS levels; and

when the set-up is successful, transmitting the contents to the user with identification of the set-up path.

11. The method of claim 10, wherein:

said contracting includes relating fees of the fee schedule to QoS path usage duration and QoS path usage levels.

12. The method of claim 10, further comprising:

said requesting including sending a path set-up request to the network provider with a path quality attribute, source address, destination address, and time duration.

13. The method of claim 10, further comprising:

in response to a user contact prior to said step of receiving, downloading to the user instructions for selection of a level of QoS from among a plurality of levels of QoS.

14. The method of claim 10, further comprising:

in response to path set-up failure, prompting the user for a request selection of the same content at one of a lower quality or a retry of the previous quality.

15. The method of claim 10, further comprising:

receiving a notification of an occurrence of a failure of delivery event from the user'"'"'s client software; and

in response to said step of receiving a notification, determining responsibility for the failure of delivery event and adjusting payment responsibility according to the determined responsibility.

16. The method of claim 10, further comprising:

in response to path set-up failure, providing the user with an alternative QoS and blocking the user from selecting the previously selected QoS and a higher QoS.

17. The method of claim 10, further comprising:

after and in relation to said requesting, receiving information from the network provider of currently available paths.

18. A method performed while communicating by a data transmission network between a user, a service provider and a network provider, said method being machine performed and comprising the steps of:

managing a database linking data related to a plurality of different QoS levels of paths through the network with usage by at least one of the providers;

receiving a request related to a one of the QoS levels of paths; and

means responsive to the request, for managing payment to the network provider based upon path usage when the request results in a successful path set-up.

19. The method of claim 18, further comprising:

means for relating the payment to QoS path usage duration.

20. The method of claim 18, further comprising:

means for relating the payment to QoS path usage levels.

21. The method of claim 18, further comprising:

means for relating the payment to QoS path usage duration and QoS path usage levels.

22. The method of claim 21, further comprising:

means response to path set-up failure for changing the payment.

23. The method of claim 21, further comprising:

means responsive to an occurrence of a failure of delivery event for determining responsibility for the failure of delivery event and adjusting payment responsibility according to the determined responsibility.

24. The method of claim 18, further comprising:

means responsive to an occurrence of a failure of delivery event for providing the user with an alternative QoS and blocking the user from selecting the previously selected QoS and a higher QoS.

25. The method of claim 18, further comprising:

means response to path set-up failure for changing the payment.

26. The method of claim 18, further comprising:

means responsive to an occurrence of a failure of delivery event for determining responsibility for the failure of delivery event and adjusting payment responsibility according to the determined responsibility.

27. A network node, comprising:

a computer readable storage having computer readable code that is executable for physically implementing the method of claim 18;
