Peer-to-peer sharing in a content centric network
First Claim
1. A computer-implemented method, comprising:
- receiving, by a content consuming device, in response to a first interest for a piece of content based on an original name, a first content object that includes a list of one or more name prefixes associated with the original name,wherein a name is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level,wherein the original name corresponds to an original root manifest that indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, andwherein the original root manifest is registered with a tracking service;
receiving, in response to a second interest based on a name prefix from the list, a second content object that is the original root manifest;
selecting a peer node based on the name prefix, wherein the peer node stores one or more of the original content objects;
determining which original content objects are stored at the selected peer node; and
generating a third interest for a respective content object of the original content objects, wherein the name for the third interest includes the name prefix used to select the peer node, and wherein the third interest includes a COH value for a determined original content object stored at the selected peer node.

Abstract
The system receives a list of one or more name prefixes associated with an original name, wherein the original name corresponds to an original root manifest that indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, and wherein the original root manifest is registered with a tracking service. Based on a name prefix from the list, the system receives the original root manifest and selects a peer node that stores one or more of the original content objects. The system determines which original content objects are stored at the selected peer node and generates an interest for an original content object, wherein the name for the interest includes the name prefix, and wherein the third interest includes a COH value for an original content object stored at the selected peer node.

1. A computer-implemented method, comprising:
-
receiving, by a content consuming device, in response to a first interest for a piece of content based on an original name, a first content object that includes a list of one or more name prefixes associated with the original name, wherein a name is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level, wherein the original name corresponds to an original root manifest that indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, and wherein the original root manifest is registered with a tracking service; receiving, in response to a second interest based on a name prefix from the list, a second content object that is the original root manifest; selecting a peer node based on the name prefix, wherein the peer node stores one or more of the original content objects; determining which original content objects are stored at the selected peer node; and generating a third interest for a respective content object of the original content objects, wherein the name for the third interest includes the name prefix used to select the peer node, and wherein the third interest includes a COH value for a determined original content object stored at the selected peer node. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A computer-implemented method, comprising:
-
receiving, by a tracking device, an original root manifest for registration, wherein the original root manifest indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, wherein the original root manifest further indicates an original name, an original name prefix associated with the original name, and a signature of a publisher of the original root manifest, and wherein a name is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level; verifying the signature of the publisher based on a public key of the publisher; adding the original name prefix to a list that indicates one or more name prefixes associated with the original name; generating a content object that indicates the list in response to a request for a content object indicating the one or more name prefixes associated with the original name. - View Dependent Claims (10, 11, 12)

13. A computer system for accessing content, the system comprising:
-
a processor; a storage device coupled to the processor and storing instructions that when executed by a computer cause the computer to perform a method, the method comprising; receiving, by a content consuming device, in response to a first interest for a piece of content based on an original name, a first content object that includes a list of one or more name prefixes associated with the original name, wherein a name is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level, wherein the original name corresponds to an original root manifest that indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, and wherein the original root manifest is registered with a tracking service; receiving, in response to a second interest based on a name prefix from the list, a second content object that is the original root manifest; selecting a peer node based on the name prefix, wherein the peer node stores one or more of the original content objects; determining which original content objects are stored at the selected peer node; and generating a third interest for a respective content object of the original content objects, wherein the name for the third interest includes the name prefix used to select the peer node, and wherein the third interest includes a COH value for a determined original content object stored at the selected peer node. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A computer system for accessing content, the system comprising:
-
a processor; a storage device coupled to the processor and storing instructions that when executed by a computer cause the computer to perform a method, the method comprising; receiving, by a tracking device, an original root manifest for registration, wherein the original root manifest indicates a set of original content objects and includes a set of content object hash (COH) values for the indicated set of original content objects, wherein the original root manifest further indicates an original name, an original name prefix associated with the original name, and a signature of a publisher of the original root manifest, and wherein a name is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level; verifying the signature of the publisher based on a public key of the publisher; adding the original name prefix to a list that indicates one or more name prefixes associated with the original name; generating a content object that indicates the list in response to a request for a content object indicating the one or more name prefixes associated with the original name. - View Dependent Claims (22, 23, 24)
