Abstract

Generally discussed herein are systems, devices, and methods for populating a cache in an information-centric network. A device of an ICN can include a content store including published content and attributes of the published content stored thereon, the attributes including at least two of a device from which the content originated attribute, a lineage attribute, and a service level agreement attribute, and content processing circuitry coupled to the content store, the content processing circuitry configured to manage the published content based on the attributes.

Claims

1. A method performed by a device of an information-centric network (ICN), the method comprising:

removing, by processing circuitry of the device and from a content store including content and corresponding attributes stored thereon, first content associated with a first service level agreement that has expired and after removing the first content;

removing second content, from the content store, with an associated time-to-live that has expired;

after removing the second content, determine that there is insufficient space in the content store to store new content; and

removing third content, from the content store, associated with a second associated service level agreement that has not expired.

2. The method of claim 1, wherein the attributes further include at least two of a durability attribute indicating whether content is to be retained when the device is powered off, a device type attribute indicating whether the device is capable of wireless communication, a quality of service attribute, a popularity attribute indicating how many users access the content relative to other content in the content store, a latency attribute that indicates an amount of time it takes to communicate data, a bandwidth attribute that indicates a spectral or temporal availability of a link, and a content type attribute that indicates whether content is for streaming or static display.

3. The method of claim 1, further comprising issuing an alert to a subscriber indicating that the second service level agreement has been violated.

4. The method of claim 1, further comprising:

issuing a message to other nodes of a cluster indicating that the device is going to be unavailable;

receiving, from the other nodes, one or more interest packets for contentstored on its content store; and

providing the content indicated by the one or more interest packets to the other nodes of the cluster.

5. The method of claim 4, further comprising determining at least one of 1) a signal strength of a signal from the node is less than a signal strength threshold, (2) a battery level of the node is less than a battery threshold, and (3) the device will be put in a sleep mode in a specified amount of time.

6. The device of claim 5, further comprising issuing the message to the other nodes includes the content processing circuitry to issue the message in response to the determining at least one of (1) a signal strength of a signal from the node is less than a signal strength threshold, (2) a battery level of the node is less than a battery threshold, and (3) the node will be put in a sleep mode in a specified amount of time.

7. The device of claim 6, further comprising after providing the content indicated by the one or more interest packets to the other nodes of the cluster, perform a handoff to a network different from the network to which the nodes of the cluster are connected.

8. The method of claim 1, further comprising providing the content indicated by the one or more interest packets includes the content processing circuitry to provide attributes with the content in an extended content packet, the attributes comprising at least one of a lineage attribute, an origination device attribute, and a service level agreement attribute.

9. A device of an information-centric network, the device comprising:

a content store including content and attributes of the content stored thereon, the attributes including a service level agreement attribute and a time-to-live attribute; and

content processing circuitry coupled to the content store, the content processing circuitry to;

remove first content from the content store associated with a first service level agreement that has expired and after removing the first content;

remove second content from the content store with an associated time-to-live that has expired;

after removing the second content determine that there is insufficient space in the content store to store new content in the content store; and

remove third content from the content store associated with a second associated service level agreement that has not expired.
