Abstract

A system comprising a plurality of peer caches associated with a corresponding plurality of content owners; shared ledger logic having a channel for each content owner of a plurality of content owners, the shared ledger logic to maintain a shared ledger data structure and to perform the operations of: in response to receipt of a first content title, responsively recording a first ledger entry for the first content title which is visible to a first content owner which owns the first content title; receiving an encryption key from the content owner, wherein the first content title comprises an encrypted content title encrypted with the key; storing the encrypted content title on one or more network storage devices; and when the encrypted content title reaches an edge cache, using the key to decrypt the encrypted content title and updating the first ledger entry to identify the edge cache.

Claims (26)

1. A system comprising:

a first cache to store content titles from one or more content providers and to selectively distribute the content titles to a plurality of secondary caches integrated with a corresponding plurality of mobile environments that each comprise a transportation vehicle or vessel, a content title of the content tiles comprising a plurality of title segments; and

a content collector coupled to the first cache, the content collector to cause title segments to be collected from the plurality of secondary caches and stored in the first cache, the content collector to identify the title segments to be collected and stored in the first cache based on an evaluation of aggregate cache usage data provided by the plurality of secondary caches, including cache miss events of the plurality of secondary caches within the corresponding plurality of mobile environments.

2. The system of claim 1 , wherein selectively distributing the content titles comprises transmitting manifests of the content titles to the plurality of secondary caches, the manifests indicating one or more stream rates corresponding to the content titles.

3. The system of claim 2 , wherein a manifest of a content title is transformed prior to transmitting to a secondary cache of the plurality of secondary caches, wherein the transformation of the manifest removes one or more entries associated with one or more highest stream rates from the manifest.

4. The system of claim 3 , wherein the content title associated with the transformed manifest is available to the plurality of secondary caches upon corresponding transportation vehicles or vessels having a lower capacity connection with the first cache, while a corresponding content title associated with the manifest before the transformation is available to the plurality of secondary caches upon the corresponding transportation vehicles or vessels having a higher capacity connection with the first cache.

5. The system of claim 1 , wherein the evaluation of the aggregate cache usage data comprises detecting one or more trigger events associated with a particular content title.

6. The system of claim 5 , wherein the one or more trigger events comprises a cache miss threshold or content request threshold being reached.

7. The system of claim 6 , wherein responsive to a first trigger event associated with a first one or more cache miss or content request thresholds, the content collector is to attempt to collect all title segments for a first content title at all or a specified subset of stream rates in which the first content title is encoded.

8. The system of claim 1 , wherein the content collector is to maintain a content retrieval queue, and wherein content retrieval operation is performed in a prioritized order, each retrieval operation associated with a particular content title.

9. A method comprising:

storing content titles in a first cache from one or more content providers, the content titles to be selectively distributed to a plurality of secondary caches integrated with a corresponding plurality of mobile environments that each comprise a transportation vehicle or vessel, a content title of the content tiles comprising a plurality of title segments; and

causing title segments to be collected from the plurality of secondary caches and stored in the first cache, wherein the title segments to be identified, collected, and stored in the first cache based on an evaluation of aggregate cache usage data provided by the plurality of secondary caches, including cache miss events of the plurality of secondary caches within the corresponding plurality of mobile environments.

10. The method of claim 9 , wherein selectively distributing the content titles comprises transmitting manifests of the content titles to the plurality of secondary caches, the manifests indicating one or more stream rates corresponding to the content titles.

11. The method of claim 10 , wherein a manifest of a content title is transformed prior to transmitting to a secondary cache of the plurality of secondary caches, wherein the transformation of the manifest removes one or more entries associated with one or more highest stream rates from the manifest.

12. The method of claim 11 , wherein the content title associated with the transformed manifest is available to the plurality of secondary caches upon corresponding transportation vehicles or vessels having a lower capacity connection with the first cache, while a corresponding content title associated with the manifest before the transformation is available to the plurality of secondary caches upon corresponding transportation vehicles or vessels having a higher capacity connection with the first cache.

13. The method of claim 9 , wherein the evaluation of the aggregate cache usage data comprises detecting one or more trigger events associated with a particular content title.

14. The method of claim 9 , wherein a content retrieval queue is maintained, and wherein content retrieval operation is performed in a prioritized order, each retrieval operation associated with a particular content title.

15. A non-transitory machine-readable medium having program code stored thereon which, when executed by a machine causes the machine to perform:

storing content titles in a first cache from one or more content providers, the content titles to be selectively distributed to a plurality of secondary caches integrated with a corresponding plurality of mobile environments that each comprise a transportation vehicle or vessel, a content title of the content tiles comprising a plurality of title segments; and

causing title segments to be collected from the plurality of secondary caches and stored in the first cache, wherein the title segments to be identified, collected, and stored in the first cache based on an evaluation of aggregate cache usage data provided by the plurality of secondary caches, including cache miss events of the plurality of secondary caches within the corresponding plurality of mobile environments.

16. The non-transitory machine-readable medium of claim 15 , wherein selectively distributing the content titles comprises transmitting manifests of the content titles to the plurality of secondary caches, the manifests indicating one or more stream rates corresponding to the content titles.

17. The non-transitory machine-readable medium of claim 16 , wherein a manifest of a content title is transformed prior to transmitting to a secondary cache of the plurality of secondary caches, wherein the transformation of the manifest removes one or more entries associated with one or more highest stream rates from the manifest.

18. The non-transitory machine-readable medium of claim 15 , wherein the evaluation of the aggregate cache usage data comprises detecting one or more trigger events associated with a particular content title.

19. The non-transitory machine-readable medium of claim 18 , wherein the one or more trigger events comprises a cache miss threshold or content request threshold being reached.

20. The non-transitory machine-readable medium of claim 15 , wherein a content retrieval queue is maintained, and wherein content retrieval operation is performed in a prioritized order, each retrieval operation associated with a particular content title.
