Abstract

Distributed Internet caching via multiple node caching management. Caching decisions and management are performed based on information corresponding to more than one caching node device (sometimes referred to as a distributed caching node device, distributed Internet caching node device, and/or DCN) within a communication system. The communication system may be composed of one type or multiple types of communication networks that are communicatively coupled to communicate there between, and they may be composed of any one or combination types of communication links therein [wired, wireless, optical, satellite, etc.]). In some instances, more than one of these DCNs operate cooperatively to make caching decisions and direct management of content to be stored among the more than one DCNs. In an alternative embodiment, a managing DCN is operative to make caching decisions and direct management of content within more than one DCNs of a communication system.

the second cache report indicates identification of at least one additional caching node device that provides a plurality of requests to the second caching node device for the second content.

6. The apparatus of claim 1, wherein:

when the first caching node device selectively caches the first content within the first caching node device, the first caching node device is operative to transmit the first cache report to at least one additional caching node device.

7. The apparatus of claim 1, wherein:

when the second caching node device selectively caches the second content within the second caching node device, the second caching node device is operative to transmit the second cache report to at least one additional caching node device.

8. The apparatus of claim 1, wherein:

the first caching node device and the second caching node device operate cooperatively to cache a plurality of content, the plurality of content includes the first content and the second content, among the first caching node device and the second caching node device.

9. The apparatus of claim 1, further comprising a managing caching node device that is operative to:

communicate with the first caching node device, the second caching node device, the third caching node device, and the fourth caching node device; and

direct each of the first caching node device, the second caching node device, the third caching node device, and the fourth caching node device to cache a plurality of content, the plurality of content includes the first content and the second content, among the first caching node device, the second caching node device, the third caching node device, and the fourth caching node device.

10. An apparatus, comprising:

a first caching node device that is operative to;

generate a first cache report corresponding to the first caching node device;

receive a second cache report corresponding to a second caching node device; and

based on the second cache report, selectively cache content within the first caching node device or transmit the content and the first cache report to the second caching node device or to a third caching node device.

11. The apparatus of claim 10, wherein, at least one:

the first cache report indicates cache storing capability of the first caching node device; and

the second cache report indicates cache storing capability of the second caching node device.

12. The apparatus of claim 10, wherein, at least one:

the first cache report indicates cache history corresponding to the content or at least one additional content that has been stored within the first caching node device or communicated via the first caching node device; and

the second cache report indicates cache history corresponding to the content or at least one additional content that has been stored within the second caching node device or communicated via the second caching node device.

13. The apparatus of claim 10, wherein, at least one:

the first cache report indicates identification of at least one additional caching node device that provides a plurality of requests to the first caching node device for the content.

14. The apparatus of claim 10, wherein:

when the first caching node device selectively caches content within the first caching node device, the first caching node device is operative to transmit the first cache report to at least one additional caching node device.

15. The apparatus of claim 10, wherein the first caching node device is operative to:

receive a third cache report corresponding to a fourth caching node device; and
