Abstract

A server includes first logic to receive a message identifying a subscriber device and including information relating to content requested by the subscriber device; and second logic to determine whether adequate network resources exist for providing the requested content to the subscriber device, and to reserve the network resources when adequate network resources are determined to exist.

Claims

1. A server comprising:

a memory to store instructions; and

a processor to execute the instructions to;

receive a message identifying a subscriber device and including information relating to content requested by the subscriber device;

determine whether adequate network resources exist for providing the requested content to the subscriber device,

reserve the network resources when adequate network resources are determined to exist, and

transmit a second message to a remote device indicating that adequate network resources have been reserved, the second message causing the remote device to provide the content to the subscriber device.

2. The server of claim 1 where the network resources include a bandwidth and quality of service for the content.

3. The server of claim 1 where, when determining whether adequate network resources exist for providing the requested content to the subscriber device, the processor is further to:

determine a maximum bandwidth available at one or more congestion points associated with the subscriber device via one of a database lookup operation or querying the one or more congestion points.

4. The server of claim 1 where, when determining whether adequate network resources exist for providing the requested content to the subscriber device, the processor is further to:

determine a bandwidth currently available at one or more congestion points associated with the subscriber device via a monitoring operation.

5. The server of claim 1 where the message further includes one or more of a value indicating whether the content is being played or stopped, an address associated with the subscriber device, a port number associated with the subscriber device, a bit rate for the content, a quality of service for the content, or a protocol to be used to transmit the content to the subscriber device.

6. A method, performed by a device, for reserving resources for a subscriber device, the method comprising:

receiving a message identifying a subscriber device and including information relating to content requested by the subscriber device;

determining, in response to receiving the message, whether adequate network bandwidth or quality of service exists for providing the requested content to the subscriber device;

reserving the network bandwidth or quality of service for providing the requested content to the subscriber device when adequate network bandwidth or quality of service is determined to exist; and

transmitting an authorization message to a remote device in response to reserving the network bandwidth or quality of service, the authorization message causing the remote device to provide the content to the subscriber device.

7. The method of claim 6 where the information relating to the content includes one or more of a value representing a bandwidth at which the content is to be provided or a quality of service for the content.

8. The method of claim 6 where determining whether adequate network bandwidth or quality of service exists includes:

determining a maximum bandwidth available at one or more congestion points associated with the subscriber device via one of a database lookup operation or querying the one or more congestion points.

9. The method of claim 6 where determining whether adequate network bandwidth or quality of service exist includes:

determining a bandwidth currently available at one or more congestion points associated with the subscriber device via a monitoring operation.

10. The method of claim 6 where the message includes a value indicating whether the content is being played or stopped, an address associated with the subscriber device, a port number associated with the subscriber device, a bit rate for the content, a quality of service for the content, or a protocol to be used to transmit the content to the subscriber device.

11. The method of claim 6 further comprising:

transmitting a failure message to a remote device when adequate network bandwidth or quality of service is determined not to exist, the failure message causing the remote device to deny the subscriber device the requested content.

12. A network comprising:

a media server to;

receive, from a subscriber device, a request for content;

transmit a message, the message identifying the subscriber device and including information relating to the content; and

a service activation device to;

receive the message from the media server,

identify, in response to receiving the message, bandwidth and quality of service requirements for the content,

determine whether network resources needed to provide the identified bandwidth and quality of service requirements exist,

reserve the network resources when the network resources needed to provide the identified bandwidth and quality of service requirements exist, and

transmit a second message to the media server in response to reserving the network resources, the second message causing the media server to provide the content to the subscriber device.

13. The network of claim 12, where the media server is associated with a plurality of configuration properties, the plurality of configuration properties including information identifying a service activation component to be executed on a remote device and a list of information to be passed to the service activation component.

14. The network of claim 13, where the list of information to be passed to the service activation component includes one or more of a value indicating whether the content is being played or stopped, an address associated with the subscriber device, a port number associated with the subscriber device, a bit rate for the content, a quality of service profile for the content, or a protocol to be used to transmit the content to the subscriber device.

15. The network of claim 13, where, when transmitting the message, the media server is further to:

transmit the message to the service activation device via an intermediate remote device.

16. The network of claim 15 where the plurality of configuration properties further includes an address identifying the intermediate remote device.

17. The network of claim 12 where the media server is further to receive information from the service activation device indicating whether the network resources needed to provide the identified bandwidth and quality of service requirements exist.

18. The network of claim 12 where the media server is further to deny the request for content when the network resources needed to provide the identified bandwidth and quality of service requirements are determined not to exist.
