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.

First claim

What is claimed is:

1. A method comprising:
receiving, by a computing device and from a particular network device, a particular quantity of resources,
the particular quantity of resources, received from the particular network device, being greater than a threshold quantity of resources,
resources, of the particular quantity of resources received from the particular network device, including video data, audio data, image data, or text;

storing, by the computing device and in a data structure, information identifying the particular network device based on the particular quantity of resources being greater than the threshold quantity of resources;
receiving, by the computing device and from a client device, a request for a resource;
determining, by the computing device, that the client device is requesting the resource from the particular network device based on information provided in the request and the data structure;
terminating, by the computing device, a connection for the request at the computing device based on:
the information identifying the particular network device that is stored in the data structure based on the particular quantity of resources being greater than the threshold quantity of resources, and
the client device requesting the resource from the particular network device;

selecting, by the computing device, a target device for the resource based on terminating the connection at the computing device,
the target device being selected based on one or more conditions of a network associated with the computing device,
the one or more conditions including one or more of a bandwidth of the network or a load on the network;

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 that the client device is requesting the resource from the particular network device includes:
extracting at least one of:
a destination Internet protocol (IP) address from the request,
an IP address of the client device from the request, or
information identifying a destination port associated with the request; and

determining, based on the at least one of the destination IP address, the IP address of the client device, or the destination port, that the client device is requesting the resource from the particular network 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 device, a quantity of resources,
the quantity of resources, received from the device, being greater than a threshold quantity of resources,
resources, of the quantity of resources received from the device, including video data, audio data, image data, or text;

store, in a data structure, information identifying the device based on the quantity of resources being greater than the threshold quantity of resources;
receive, from a client device, a request for a resource;
determine, based on information included in the request and the data structure, that the client device is requesting the resource from the device;
terminate a connection for the request at the network device based on:
the information identifying the device that is stored in the data structure based on the quantity of resources being greater than the threshold quantity of resources, and
the client device requesting the resource from the device;

determine, based on the connection for the request being terminated,

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,
the target device being selected based on one or more conditions of a network associated with the network device,
the one or more conditions including one or more of a bandwidth of the network or a load on the network;

provide, when the resource is not stored in the local cache, the request to the selected target device;
receive, based on providing the request to the selected target device, the resource from the selected target device; and
provide, based on receiving the resource from the selected target device, the resource to the client device.

11. The network device of claim 10 , where, when determining that the client device is requesting the resource from the device, the processor is to:
extract at least one of:
a destination Internet protocol (IP) address from the request,
an IP address of the client device from the request, or
information identifying a destination port of the request, and

determine, based on the at least one of the destination IP address, the IP address of the client device, or the destination port, that the client device is requesting the resource from the device.

12. The network device of claim 10 , where the processor is further to:
receive another request for the resource;
determine that the resource is being requested from another device; and
forward the request to the other 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 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.
