Methods and apparatus for monitoring content delivery
Methods and apparatus are provided for content delivery. In one aspect, a method in a traffic monitor in a communications network comprises responsive to a notification that content is being delivered to a device from a content delivery network according to a data transfer policy, the notification including an indication of the data transfer policy, monitoring delivery of the content from the content delivery network to the device and, responsive to a detection that the delivery of the content violates the data transfer policy, performing a notification action.
1. A method in a traffic monitor in a communications network, the method comprising:
responsive to a notification that content is being delivered to a device from a content delivery network according to a data transfer policy, wherein the data transfer policy indicates a property of the data delivered to the device, a property of the data itself, a content quality, a maximum data rate, or a maximum content quality;
determining that the content that is being delivered to the device is zero-rated specifically for the device to which that particular content is to be delivered and that the data transfer policy comprises one or more policies based on the content being zero-rated for the device, the notification including an indication of the data transfer policy specifying that the device is to request a version of the content that is of a lower quality than what is otherwise available for the content,
monitoring delivery of the content from the content delivery network to the device; and responsive to a detection that the delivery of the content comprises delivery of a version of the content that is of a higher quality than what is specified in the data transfer policy, performing a notification action notifying a node in the communications network, the node separate from the device.
2. The method of claim 1 , wherein performing the notification action comprises sending an alarm notification to the node in the communications network.
3. The method of claim 1 , wherein performing the notification action comprises notifying an enforcement entity to enforce the data transfer policy for the delivery of the content from the content delivery network to the device.
4. The method of claim 3 , wherein performing the notification action comprises notifying the enforcement entity to throttle the delivery of the content from the content delivery network to the device.
5. The method of claim 1 , wherein monitoring delivery of the content from the content delivery network to the device comprises monitoring communications that match a 5 tuple associated with delivery of the content from the content delivery network to the device.
6. The method of claim 1 , further comprising, responsive to a request by the device to receive the content from the content delivery network according to the data transfer policy, sending a redirection instruction to the device redirecting the device to the content delivery network, wherein the redirection instruction includes an indication of the data transfer policy.
7. The method of claim 6 , wherein the redirection instruction includes a Uniform Resource Locator (URL) to the content within the content delivery network, wherein the URL includes the indication Of the data transfer policy.
8. The method of claim 6 , wherein the redirection instruction includes an indication of the data transfer policy that is encoded, encrypted or scrambled.
9. The method of claim 1 , wherein a request to receive content from a content delivery network comprises a request for a manifest associated with the content.
10. An apparatus for monitoring content delivery, the apparatus comprising a processor and a memory, the memory containing instructions executable by the processor such that the apparatus is operable to:
responsive to a notification that content is being delivered to a device from a content delivery network according to a data transfer policy, wherein the data transfer policy indicates a property of the data delivered to the device, a property of the data itself, a content quality, a maximum data rate, or a maximum content quality;
determine that the content that is being delivered to the device is zero-rated specifically for the device to which that particular content is to be delivered and that the data transfer policy comprises one or more policies based on the content being zero-rated for the device, the notification including an indication Of the data transfer policy specifying that the device is to request a version Of the content that is Of a lower quality than what is otherwise available for the content,
monitor delivery Of the content from the content delivery network to the device; and
responsive to a detection that the delivery of the content comprises delivery of version of the content that is of a higher quality than what is specified in the data transfer policy, perform a notification action that notifies a node in the communications network, the node separate from the device.
11. The apparatus of claim 10 , wherein the memory contains instructions executable by the processor such that the apparatus is operable to perform the notification action by sending an alarm notification to the node in the communications network.
12. The apparatus of claim 10 , wherein the memory contains instructions executable by the processor such that the apparatus is operable to perform the notification action by notifying an enforcement entity to enforce the data transfer policy for the delivery of the content from the content delivery network to the device.
13. The apparatus of claim 12 , wherein the memory contains instructions executable by the processor such that the apparatus is operable to perform the notification action by notifying an enforcement entity to throttle the delivery of the content from the content delivery network to the device.
14. The apparatus of claim 10 , wherein the memory contains instructions executable by the processor such that the apparatus is operable to monitor delivery Of the content from the content delivery network to the device monitoring communications that match a 5 tuple associated with delivery of the content from the content delivery network to the device.
15. The apparatus of claim 10 , wherein the memory contains instructions executable by the processor such that the apparatus is operable to send a redirection instruction to the device redirecting the device to the content delivery network in response to request by the device to receive the content from the content delivery network according to the data transfer policy, wherein the redirection instruction includes an indication of the data transfer policy.
16. The apparatus of claim 15 , wherein the redirection instruction includes a Uniform Resource Locator (URL) to the content within the content delivery network, wherein the URL includes the indication of the data transfer policy.
17. The apparatus of claim 15 , wherein the redirection instruction includes an indication of the data transfer policy that is encoded, encrypted or scrambled.
18. The apparatus of claim 10 , wherein a request to receive content from a content delivery network comprises a request for a manifest associated with the content.
