Abstract

A device receives, from a client device, a request for a resource, and determines, based on information provided in the request, whether to terminate a connection for the request at the device. The device forwards the request to a network when the connection is not terminated at the device, and selects a target device for the resource when the connection is terminated at the device. The device also provides the request to the selected target device, receives the resource from the selected target device, and provides the resource to the client device.

Claims

1. A method performed by a computing device, the method comprising:

receiving, by the computing device and from a client device, a request for a resource;

determining, by the computing device and based on information provided in the request, whether to terminate a connection for the request at the computing device;

forwarding, by the computing device, the request to a network when the connection is not terminated at the computing device;

selecting, by the computing device, a target device for the resource when the connection is terminated at the computing device;

providing, by the computing device, the request to the selected target device;

receiving, by the computing device, the resource from the selected target device; and

providing, by the computing device, the resource to the client device.

2. The method of claim 1, where determining whether to terminate the connection comprises:

extracting a destination Internet protocol (IP) address from the request;

extracting an IP address of the client device from the request;

extracting a destination port of the request; and

determining, based on at least one of the destination IP address, the IP address of the client device, and the destination port, whether to terminate the connection for the request at the computing device.

3. The method of claim 1, where selecting the target device for the resource comprises:

determining whether the resource is stored in a local cache provided in the computing device; and

selecting the local cache as the target device when the resource is stored in the local cache.

4. The method of claim 3, where, when the resource is not stored in the local cache, selecting the target device for the resource further comprises:

providing, to a routing broker server, a query for the requested resource;

receiving, from the routing broker server and based on the query, an identification of the target device; and

connecting with the target device based on the identification.

5. The method of claim 1, where providing the request to the selected target device comprises:

providing a proxy of the request to the selected target device.

6. The method of claim 5, where the proxy of the request includes the request and an Internet protocol (IP) address of the computing device.

7. The method of claim 1, where providing the resource to the client device comprises:

providing a proxy of the resource to the client device.

8. The method of claim 7, where the proxy of the resource includes the resource and an Internet protocol (IP) address of the computing device.

9. The method of claim 1, where the resource comprises one or more of audio data, video data, text, or a service.

10. A network device, comprising:

a memory to store a local cache of resources; and

a processor to;

receive, from a client device, a request for a resource,

terminate, based on information provided in the request, a connection for the request at the network device,

determine whether the resource is stored in the local cache,

select the local cache as a target device for the resource when the resource is stored in the local cache,

select the target device, from a plurality of devices storing resources, when the resource is not stored in the local cache,

provide the request to the selected target device,

receive the resource from the selected target device, and

provide the resource to the client device.

11. The network device of claim 10, where the processor is further to:

extract a destination Internet protocol (IP) address from the request,

extract an IP address of the client device from the request,

extract a destination port of the request, and

determine, based on at least one of the destination IP address, the IP address of the client device, and the destination port, whether to terminate the connection for the request at the network device.

12. The network device of claim 10, where the processor is further to:

forward the request to a network when the connection is not terminated at the network device.

13. The network device of claim 10, where, when the resource is not stored in the local cache, the processor is further to:

provide, to a routing broker server, a query for the requested resource,

receive, from the routing broker server and based on the query, an identification of the target device, and

connect with the target device based on the identification.

14. The network device of claim 10, where, when providing the request to the selected target device, the processor is further to:

associate, with the request, an Internet protocol (IP) address of the network device to create a modified request, and

provide the modified request to the selected target device.

15. The network device of claim 10, where, when providing the resource to the client device, the processor is further to:

associate, with the resource, an Internet protocol (IP) address of the network device to create a modified resource, and

provide the modified resource to the client device.

16. The network device of claim 10, where the resource comprises one or more of audio data, video data, text, or a service.

17. One or more non-transitory computer-readable media storing instructions executable by one or more processors of an edge device, the media comprising:

one or more instructions to receive, from a client device, a request for a resource;

one or more instructions to terminate, based on information provided in the request, a connection for the request at the edge device;

one or more instructions to select a target device for the resource when the connection is terminated at the edge device;

one or more instructions to provide the request to the selected target device;

one or more instructions to receive the resource from the selected target device; and

one or more instructions to provide the resource to the client device.

18. The media of claim 17, where the media further comprises:

one or more instructions to determine, from the request, at least one of a destination Internet protocol (IP) address, an IP address of the client device, and a destination port; and

one or more instructions to determine, based on at least one of the destination IP address, the IP address of the client device, and the destination port, whether to terminate the connection for the request at the edge device.

19. The media of claim 17, where the media further comprises:

one or more instructions to forward the request to a network when the connection is not terminated at the edge device.

20. The media of claim 17, where the media further comprises:

one or more instructions to determine whether the resource is stored in a local cache provided in or directly connected to the edge device; and

one or more instructions to select the local cache as the target device when the resource is stored in the local cache.

21. The media of claim 17, where the media further comprises:

one or more instructions to provide, to a routing broker server, a query for the requested resource;

one or more instructions to receive, from the routing broker server and based on the query, an identification of the target device; and

one or more instructions to connect with the target device based on the identification.

22. The media of claim 17, where the request is provided to the selected target device via a proxy of the request that includes the request and an Internet protocol (IP) address of the edge device.

23. The media of claim 17, where the resource is provided to the client device via a proxy of the resource that includes the resource and an Internet protocol (IP) address of the edge device.
