Abstract

A system and method for distributed caching, the system having at least one network-connected storage device, a content server, and a control server. The control server is configured to discover the at least one network-connected storage device, collect device information from the at least one network-connected storage device, where the device information comprises a device location, assign each of the at least one network-connected storage device to a device domain based on each device location, and provide the content server with the device information for the one or more network-connected storage.

First claim

What is claimed is:

1. A system comprising:
at least one network-connected device having an identifier;
a content server; and
a control server, the control server comprising:
a memory; and
a processor configured to execute instructions from the memory that, when executed by the processor, cause the processor to:
discover the at least one network-connected device;
collect device information from the at least one network-connected device, wherein the at least one network-connected device comprises a storage device comprising an Ethernet solid state drive (eSSD), and wherein the identifier of the at least one network-connected device comprises a network protocol address, wherein the device information comprises a device location based on the network protocol address;
assign the at least one network-connected device to a device domain based on the device information; and
provide the content server with the device information for the at least one network-connected device,
wherein the content server is configured to transmit content to the at least one network-connected device based on the device information.

2. The system of claim 1 , wherein the network protocol address comprises an internet protocol (IP) address.

3. The system of claim 1 , the instructions further comprising generating a device table, wherein the device table comprises an entry for the at least one network-connected device, the entry comprising at least one of a cache device identifier, the device location, or the device domain.

4. The system of claim 3 , wherein the cache device identifier comprises an IP address.

5. The system of claim 1 , wherein the content server comprises a cached content table, the cached content table comprising a content entry for the content stored on the at least one network-connected device, wherein the content entry comprises at least one of a cache device identifier or a content identifier.

6. The system of claim 5 , wherein the at least one network-connected device comprises a hosted content table, wherein the hosted content table comprises an authorization entry for verifying a client device's access rights to the content stored on the network-connected device.

7. A system comprising:
a network-connected device comprising at least one content and a domain based on a device information, the network-connected device having an identifier; and
a content server, the content server comprising:
a memory; and
a processor configured to execute instructions from the memory that, when executed by the processor, cause the processor to:
verify an access right of a client to access a requested content;
identify information of the client;
match the information of the client to a proximate domain;
update a hosted content table of the network-connected device within a nearest domain; and
deliver a redirect message to the client, wherein the network-connected device comprises a storage device comprising an Ethernet solid state drive (eSSD), and wherein the identifier of the network-connected device comprises a network protocol address, wherein the device information comprises a device location based on the network protocol address.

8. The system of claim 7 , wherein the network protocol address comprises an internet protocol (IP) address.

9. The system of claim 7 , the instructions further comprising:
verifying storage of the content within the nearest domain, wherein the information of the client comprises a location of the client, wherein updating the hosted content table of the network-connected device comprises including an authorization entry for the client, and wherein the redirect message comprises a caching device identifier.

10. The system of claim 9 , the instructions further comprising:
transmitting a first shard of the requested content to the network-connected device in the nearest domain.

11. The system of claim 10 , the instructions further comprising:
transmitting a second shard of the requested content to the network-connected device in the nearest domain.

12. The system of claim 7 , wherein the device information comprises the device location, the device location comprising a physical location.

13. A system comprising:
a network-connected device having an identifier;
a content server; and
a control server, the control server comprising:
a first memory; and
a first processor configured to execute first instructions from the first memory that, when executed by the first processor, cause the first processor to:
discover the network-connected device;
collect device information from the network-connected device, wherein the network-connected device comprises a storage device comprising an Ethernet solid state drive (eSSD), and wherein the identifier of the network-connected device comprises a network protocol address, wherein the device information comprises a device location based on the network protocol address; and
provide the content server with the identifier and the device information of the network-connected device.

14. The system of claim 13 , wherein the network protocol address comprises an internet protocol (IP) address, wherein the content server is configured to transmit content to the eSSD based on the device location.

15. The system of claim 13 , wherein the content server comprises a cached content table comprising a content entry for content stored on the network-connected device, wherein the content entry comprises a cache device identifier and a content identifier, and wherein the network-connected device comprises a hosted content table to verify a client device's access rights to the content.

16. The system of claim 13 , wherein the content server comprises:
a second memory; and
a second processor configured to execute second instructions from the second memory that, when executed by the second processor, cause the second processor to:
verify an access right of a client to access a requested content;
identify a location of the client;
match the location of the client to a nearest domain;
update a hosted content table of the network-connected device within the nearest domain to include an authorization entry for the client;
deliver a redirect message to the client, wherein the redirect message comprises a caching device identifier;
verify storage of the requested content within the nearest domain; and
transmit the requested content to the network-connected device in the nearest domain.

17. A network-connected device comprising:
a network connection;
a persistent memory storing at least one multimedia content comprising a first shard of multimedia content; and
a controller comprising:
a memory storing a hosted content table, wherein the hosted content table comprises an authorization entry for the at least one multimedia content; and
a processor, wherein the processor is configured to execute instructions from the memory that, when executed by the processor, cause the processor to:
verify an access right of a client to a requested multimedia content according to the hosted content table; and
deliver the requested multimedia content to the client via the network connection, wherein the network-connected device further comprises a storage device comprising an Ethernet solid state drive (eSSD), and wherein an identifier of the network-connected device comprises a network protocol address, wherein a device information of the network-connected device comprises a device location based on the network protocol address.

18. The network-connected device of claim 17 , wherein the n
