Abstract

A device receives, from a client device, a request for a resource, where the request provides an identifier of the client device. The device selects a target device for the resource, connects with the selected target device, and provides a proxy of the request to the selected target device, where the proxy of the request hides the identifier of the client device. The device receives the resource from the selected target device, where the resource provides an identifier of the target device. The device provides a proxy of the resource to the client device, where the proxy of the resource hides the identifier of the target 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, where the request provides an identifier of the client device;

selecting, by the computing device, a target device for the resource;

connecting the computing device with the selected target device;

providing, by the computing device, a proxy of the request to the selected target device, where the proxy of the request hides the identifier of the client device;

receiving, by the computing device, the resource from the selected target device, where the resource provides an identifier of the target device; and

providing, by the computing device, a proxy of the resource to the client device, where the proxy of the resource hides the identifier of the target device.

2. The method of claim 1, where the target device is selected from a plurality of server devices storing resources and from a local cache provided in or locally connected to the computing device.

3. The method of claim 2, where selecting the target device for the resource further comprises:

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

selecting the target device from the plurality of server devices when the resource is not stored in the local cache.

4. The method of claim 1, where the proxy of the request includes the request and substitutes an Internet protocol (IP) address of the computing device for the identifier of the client device.

5. The method of claim 1, where the proxy of the resource includes the resource and substitutes an Internet protocol (IP) address of the computing device for the identifier of the target device.

6. The method of claim 1, where the resource comprises content or a service.

7. The method of claim 1, further comprising:

receiving, from the client device, a plurality of requests for resources, where the request is one of the plurality of requests and the plurality of requests are associated with a single connection with the client device;

selecting a separate target device for each of the plurality of requests; and

retrieving the resources from the target devices associated with the plurality of requests.

8. The method of claim 1, further comprising:

receiving, from the client device, a plurality of requests for resources, where the request is one of the plurality of requests and the plurality of requests are associated with a single connection with the client device;

selecting one or more target devices for the plurality of requests; and

retrieving the resources from the one or more target devices associated with the plurality of requests.

9. The method of claim 1, further comprising:

receiving, after receiving a portion of the resource, an indication of an event associated with the selected target device or a network of the selected target device;

selecting another target device for the resource based on the event indication;

retrieving a remaining portion of the resource from the selected other target device; and

providing the portions of the resource to the client device.

10. The method of claim 9, where the event indication includes information indicating that the remaining portion of the resource cannot be retrieved from the selected target device.

11. A network device, comprising:

a processor to;

receive, from a client device, a request for a resource, where the request provides an identifier of the client device,

select a target device for the resource,

connect the network device with the selected target device,

provide a proxy of the request to the selected target device, where the proxy of the request includes the request and substitutes an Internet protocol (IP) address of the network device for the identifier of the client device,

receive the resource from the selected target device, where the resource provides an identifier of the target device, and

provide a proxy of the resource to the client device, where the proxy of the resource includes the resource and substitutes the IP address of the network device for the identifier of the target device.

12. The network device of claim 11, where the target device is selected from a plurality of server devices storing resources and from a local cache provided in or locally connected to the computing device.

13. The network device of claim 12, where, when selecting the target device for the resource, the processor is further to:

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

select the target device from the plurality of server devices when the resource is not stored in the local cache.

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

receive, from the client device, a plurality of requests for resources, where the request is one of the plurality of requests and the plurality of requests are associated with a single connection with the client device,

select a separate target device for each of the plurality of requests, and

retrieve the resources from the target devices associated with the plurality of requests.

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

receive, from the client device, a plurality of requests for resources, where the request is one of the plurality of requests and the plurality of requests are associated with a single connection with the client device,

select one or more target devices for the plurality of requests, and

retrieve the resources from the one or more target devices associated with the plurality of requests.

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

receive, after receiving a portion of the resource, an indication of an event associated with the selected target device or a network of the selected target device,

select another target device for the resource based on the event indication,

retrieve a remaining portion of the resource from the selected other target device, and

provide the portions of the resource to the client device.

17. The network device of claim 16, where the event indication includes information indicating that the remaining portion of the resource cannot be retrieved from the selected target device.

18. 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, where the request provides an identifier of the client device;

one or more instructions to select a target device for the resource from a plurality of server devices storing resources and a local cache associated with the edge device;

one or more instructions to provide a proxy of the request to the selected target device, where the proxy of the request hides the identifier of the client device;

one or more instructions to receive the resource from the selected target device, where the resource provides an identifier of the target device; and

one or more instructions to provide a proxy of the resource to the client device, where the proxy of the resource hides the identifier of the target device.

19. The media of claim 18, where the proxy of the request substitutes an Internet protocol (IP) address of the edge device for the identifier of the client device.

20. The media of claim 18, where the proxy of the resource substitutes an Internet protocol (IP) address of the edge device for the identifier of the target device.

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