Abstract

A device can process commands from a remote device that manages the local device over a content centric network. During operation, the device can receive an Interest for managing a device resource, such that the Interest'"'"'s name includes a name or a name prefix associated with the device resource, and includes a command for managing the resource. If the device determines that the name prefix corresponds to the local device, the device analyzes the Interest'"'"'s command to determine a device resource and performs the resource-managing operation on the device resource. If the name prefix does not correspond to the local device, the device performs a longest-prefix-matching lookup using the Interest'"'"'s name prefix to determine a destination for the Interest. If the Interest'"'"'s destination corresponds to a component of the local device, the device forwards the Interest to the component or a local agent for the component.

Claims

1. A computer-implemented method, comprising:

receiving, by a device, an Interest for managing a device resource, wherein the Interest'"'"'s name includes a name or a name prefix associated with the device resource, and includes a command for the device resource;

performing a longest-prefix-matching lookup using the Interest'"'"'s name to determine a destination for the Interest;

determining, from the longest-prefix-matching lookup results, that the Interest'"'"'s destination includes a component of the local device; and

forwarding the Interest to an agent for the component of the local device.

2. The method of claim 1, wherein the longest-prefix-matching lookup results includes a plurality of components, and wherein the method further comprises:

forwarding the Interest to the plurality of components;

receiving a Content Object (CO) from each of the plurality of components, wherein a respective Content Object includes a result produced by executing the command on a corresponding component;

generating a Content Object that includes a result summary for the information produced by the plurality of Content Objects; and

returning the Content Object to satisfy the Interest.

3. The method of claim 2, wherein the result summary includes at least one of:

a compilation of results produced by the plurality of components; and

one or more aggregate values that aggregate the results produced by the plurality of components.

4. The method of claim 2, wherein the result from the corresponding component includes at least one or more of:

component variables for one or more metrics;

counter values for one or more metrics; and

a configuration state.

5. The method of claim 1, wherein the component includes a hardware component of the local device, and wherein the agent runs on the local device on behalf of the hardware component.

6. The method of claim 1, wherein the component includes a software component or a hardware component that includes the agent for processing the Interest.

7. The method of claim 1, wherein the component includes at least one of:

a line card;

a temperature sensor;

a fan controller;

12. The method of claim 8, wherein the command includes an aggregation-summary command, and wherein performing the resource-managing operation involves computing an aggregated attribute from a plurality of resources of the local device.

13. The method of claim 8, wherein the command includes an alert-configuring command, and wherein performing the resource-managing operation involves configuring the device to issue an alert in response to detecting that a predetermined condition is satisfied.

14. The method of claim 13, further comprising, responsive to determining that the alert'"'"'s condition is satisfied:

processing the alert to generate an alert message; and

sending the alert message to a predetermined target device over the content centric network.

15. The method of claim 14, wherein sending the alert message involves:

determining, from the first Interest, a routable prefix for the predetermined target device;

generating a second Interest that includes the routable prefix and the alert message, wherein the second Interest includes the alert message in a payload of the Interest, or includes the alert message in a name component following the routable prefix in the first Interest'"'"'s name; and

disseminating the second Interest over the content centric network.

16. The method of claim 14, wherein the first Interest originated from the predetermined target device that is to receive the alert message, and wherein sending the alert message involves:

generating a Content Object with a name that includes the first Interest'"'"'s name, and with a payload that includes the alert message; and

returning the Content Object over the content centric network to satisfy the first Interest, and to provide the alert message to the predetermined target device.

17. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method, the method comprising:

receiving a first Interest for managing a device resource, wherein the Interest'"'"'s name includes a name or a name prefix for the resource and a command for monitoring or configuring the device resource;
