Abstract

A method of transmitting digital content via a communication network. The method comprises receiving by a computer a request for a plurality of options for delivering the digital content via a communication network, determining by a computer a demand for resources of the communication network, and creating a congestion model modeling a congestion of the communication network. The method further comprises building by a computer a plurality of options for delivering the digital content based on the determined demand for resources of the communication network and based on the congestion model, transmitting by a computer the plurality of options, receiving by a computer a boundary reservation, creating by a computer at least one uncommitted reservation based on the boundary reservation, modifying by a computer the determined demand for resources of the communication network based on the uncommitted reservation.

Claims

1. A method of transmitting digital content via a communication network, comprising:

receiving, by a computer, a request for a plurality of options for delivering the digital content via a communication network;

determining, by a computer, a demand for resources of the communication network;

creating a congestion model modeling a congestion of the communication network;

building, by a computer, a plurality of options for delivering the digital content based on the determined demand for resources of the communication network and based on the congestion model;

transmitting, by a computer, the plurality of options;

receiving, by a computer, a boundary reservation, wherein the boundary reservation comprises an uncommitted reservation of resources corresponding to a worst case consumption of network resources associated with a plurality of delivery options identified by a computer;

creating, by a computer, at least one uncommitted reservation based on the boundary reservation, wherein the at least one uncommitted reservation is determined based on potential consumption of communication network resources when fulfilling one of the plurality of digital content delivery offers;

modifying, by a computer, the determined demand for resources of the communication network based on the uncommitted reservation,

whereby a system for providing a plurality of offers for digital content delivery is supported.

2. The method of claim 1, wherein building the plurality of options comprises determining an available bit rate for delivering the digital content to a communication device based on a capacity of the communication network, based on the congestion model, and based on the determined demand for resources of the communication network and wherein one of the options defines a bit rate that is a predefined percentage of the available bit rate and wherein the other options define a bit rate that is one of less than or equal to the predefined percentage of the available bit rate.

3. The method of claim 2, wherein the available bit rate is determined based on derating the component of the determined demand for network resources that is associated with the uncommitted reservations.

4. The method of claim 1, further comprising:

receiving, by a computer, a selection of one of the offers for digital content delivery;

deleting, by a computer, the uncommitted reservation based on the selection; and

creating a committed reservation based on the selection.

5. The method of claim 1, further comprising:

receiving, by a computer, a selection of one of the offers for digital content delivery; and

changing, by a computer, the uncommitted reservation to a committed reservation based on the selection.

6. The method of claim 1, wherein creating the congestion model is based at least in part on analyzing explicit congestion notification (ECN) flags in data packets carried in the communication network.

7. A method of transmitting digital content via a communication network, comprising:

receiving, by a computer, an identification of a digital content item;

determining a digital content type and a digital content size of the digital content item;

modeling a congestion of the communication network, wherein the modeling comprises modeling a congestion in a local wireless coverage area associated with a communication device to which the digital content item is to be delivered;

determining, by a computer, a demand for resources of the communication network based at least in part on committed reservations and on uncommitted reservations, wherein each of the plurality of uncommitted reservations is determined based on potential consumption of communication network resources when fulfilling a digital content delivery offer, and wherein the uncommitted reservations correspond to worst case consumption of network resources associated with a plurality of delivery options identified by a computer; and

building, by a computer, a plurality of delivery offers based on the determined demand for resources of the communication network and based on modeling of the congestion of the communication network.

8. The method of claim 7, wherein the digital content item is one of a video file or a music file.

9. The method of claim 7, wherein the plurality of delivery offers is based in part on overloading the determined demand.

10. The method of claim 9, wherein the amount of overloading is configurable at run time.

11. The method of claim 7, wherein building the plurality of delivery offers comprises determining a price for some of the delivery offers based on the demand for resources of the communication network.

12. The method of claim 11, wherein determining the price for some of the delivery offers is further based on a profile of a user of a communication device to which the digital content is to be delivered.

13. The method of claim 7, wherein building the plurality of delivery offers comprises building at least three delivery offers.

14. A method of transmitting digital content via a communication network, comprising:

building, by a computer, a plurality of digital content delivery offers based on a model of congestion in the communication network and based on a determined demand for resources of the communication network;

storing an uncommitted reservation associated with the plurality of digital content delivery offers, wherein the uncommitted reservation is determined based on potential consumption of communication network resources when fulfilling one of the plurality of digital content delivery offers, and wherein the uncommitted reservation corresponds to a worst case consumption of network resources associated with a plurality of delivery options identified by a computer;

transmitting, by a computer, the plurality of digital content delivery offers;

receiving, by a computer, a selection of one of the plurality of digital content delivery offers;

storing a committed reservation based on the selection; and

deleting the uncommitted reservation based on the selection,

wherein the demand for resources of the communication network is determined at least in part based on at least one uncommitted reservation or on at least one committed reservation.

15. The method of claim 14, further comprising storing another uncommitted reservation associated with the plurality of digital content delivery offers, wherein the other uncommitted reservation is determined as a worst case in another dimension of potential consumption of communication network resources based on fulfilling one of the plurality of digital content delivery offers.

16. The method of claim 14, further comprising deleting an uncommitted reservation that is older than a predefined age limit.

17. The method of claim 16, wherein the predefined age limit is adapted based on a current congestion of the communication network.

18. The method of claim 16, wherein the predefined age limit is less than about 5 minutes.

19. The method of claim 16, wherein the predefined age limit is less than about 30 seconds.
