Abstract

A network entity for delivering video to a front end in accordance with service level information defining at least one service level requirement for providing a service used in delivering the video, the network entity comprising: an input for receiving a request comprising task information identifying a task to be performed requiring the service for delivery of the video; an interface for communication with processing nodes each configured to provide the service for use in delivering the video; and decision logic coupled to the interface and configured to: receive (i) the request transmitted by the video content provider, (ii) characteristics of the processing nodes, and (iii) the at least one service level requirement for providing the service; select processing node(s) based on the received characteristics and the at least one service level requirement, and communicate via the interface with the processing node(s) selected to perform the task.

First claim

The invention claimed is:

1. A network entity for delivering video content that is provided by a video content provider to a front end in accordance with service level information which defines at least one service level requirement for providing a service used in delivering the video content to the front end, the network entity comprising:
an input for receiving a request comprising task information identifying a task to be performed requiring the service for delivery of the video content to the front end;
an interface for communication with processing nodes each configured to provide the service for use in delivering the video content to the front end; and
decision logic coupled to the interface and configured to:
receive (i) the request transmitted by the video content provider, (ii) characteristics of the processing nodes, and (iii) the at least one service level requirement for providing the service;
identify any processing node based on the received characteristics and the at least one service level requirement which meets the request;
wherein if one processing node meets the request, that processing node is selected,
wherein if more than one processing node meets the request, selecting one of the processing nodes in accordance with predetermined rules, wherein the predetermined rules specify one or more characteristics for use in the selection of processing nodes,
wherein if no processing node meets the request:
identifying any combinations of processing nodes which, based on the received characteristics and the at least one service level requirement, meets the request,
wherein if a single combination of the processing nodes is identified as being able to perform the task in accordance with the at least one service level requirement, selecting the single combination of said processing nodes,
wherein if a plurality of combinations of the processing nodes are able to perform the task in accordance with the at least one service level requirement, selecting one of the plurality of combinations of the processing nodes in accordance with predetermined rules,
the decision logic being further configured to communicate via the interface with the selected processing node or combination of processing nodes to perform the task.

2. The network entity according to claim 1 , wherein the decision logic is further configured to determine if the service request comprises an indicator indicating that the task is to be performed in accordance with requested service level information;
wherein the at least one service level requirement corresponds to default service level information if the service request does not comprise the indicator; and
the at least one service level requirement corresponds to requested service level information overriding the default service level information if the service request comprises the indicator.

3. The network entity according to claim 1 , wherein the decision logic is configured to determine that only a single processing node of the processing nodes is able to perform the task in accordance with the at least one service level requirement, and in response to the determination select the single processing node and communicate via the interface with the selected single processing node to perform the task.

4. The network entity according to claim 1 , wherein the predetermined rules specify that only one of the plurality of the processing nodes able to perform the task should be selected.

5. The network entity according to claim 1 , wherein in response to determining no combination of the processing nodes is able to perform the task in accordance with the at least one service level requirement, the decision logic is configured to determine if the service level information comprises an indicator indicating that it is acceptable for the task to be performed without complying with the at least one service level requirement.

6. The network entity according to claim 5 , wherein in response to determining the service level information comprises an indicator indicating that it is acceptable for the task to be performed without complying with the at least one service level requirement, the decision logic is configured to:
select a processing node or combination of the processing nodes to perform the task;
communicate via the interface with the selected processing node or combination of the processing nodes to perform the task; and
transmit a message to the video content provider indicating that the task was performed without complying with the at least one service level requirement.

7. The network entity according to claim 5 , wherein in response to determining the service level information does not comprise an indicator indicating that it is acceptable for the task to be performed without complying with the at least one service level requirement, the decision logic is configured to transmit a message to the video content provider indicating that the task was not performed.

8. The network entity according to claim 1 , wherein the decision logic is configured to determine that a predetermined period of time has elapsed since characteristics of a processing node of the processing nodes have been received, and in response to the determination the decision logic is configured to consider the processing node for selection to perform the task using service level information that has been agreed with a service provider associated with the processing node for providing the service, instead of characteristics of the processing node.

9. The network entity according to claim 1 , wherein the decision logic is configured to determine that a predetermined period of time has elapsed since characteristics of a processing node of the processing nodes have been received, and in response to the determination the decision logic is configured to supply a test task to the processing node that is to be performed by the processing node.

10. The network entity according to claim 1 , wherein the decision logic is configured to determine based on received characteristics of a processing node that the processing node is not complying with service level agreement information that has been agreed with a service provider associated with the processing node for providing the service, and in response to the determination the decision logic is configured to remove the processing node from consideration for selection to perform the task for a predetermined period of time.

11. The network entity according to claim 1 , wherein the characteristics include one or any combination of: a geographical positions of the processing nodes; an availability of the processing nodes; a financial cost of using the processing nodes; a quality of the output provided by the processing node; a capacity of the processing nodes; a throughput of the processing nodes; and a utilization of the processing nodes.

12. The network entity according to claim 1 , wherein the service is one of: a content recommendation service, a content quality verification service, a content storage service, an electronic programming guide service, a concurrency service, a content consumer entitlement verification service, a content metadata management service, an encoding service, a geographical awareness of content consuming devices service, a device verification service, a transcoding service, a digital rights management service, a content encryption service, an analytics service, a content consumer subscriptions service, a content delivery network service, a content ingestion service, a user profile management service, a content security service, provision of a content player, a payment service, and a billing service.
