SYSTEM AND METHOD FOR DEVICE REGISTRATION AND DISCOVERY IN CONTENT-CENTRIC NETWORKS
One embodiment of the present invention provides a system for device registration and discovery in a content-centric network (CCN). During operation, the system receives, by a computer, an interest for registration of a client device. The Interest includes at least a unique identifier associated with the client device. In response to the interest, the system generates a content object, which includes at least a name assigned to the client device; and sends the content object to the client device, thereby enabling the client device to be discovered by other client devices in the CCN.
1 . A computer-executable method for device registration and discovery in a content-centric network (CCN), the method comprising:
receiving, by a computer, an interest for registration of a client device, wherein the interest includes at least a unique identifier associated with the client device;
generating a content object in response to the interest, wherein the content object includes at least a name assigned to the client device; and
sending the content object to the client device, thereby enabling the client device to be discovered by other client devices in the CCN.
2 . The method of claim 1 , wherein the interest further includes one or more of:
a public key associated with the client device;
a device type;
a device model number; and
a device identifier in an arbitrary format.
3 . The method of claim 1 , wherein the content object further includes one or more of:
a routable name prefix assigned to the client device;
a subdirectory device-discovery namespace;
one or more namespaces for the client device to publish data under; and
a namespace for the client device to obtain a signing key.
4 . The method of claim 1 , wherein the interest has a pre-determined name prefix.
5 . The method of claim 4 , further comprising notifying the client device of the pre-determined name prefix during an initial configuration of the client device.
6 . The method of claim 4 , wherein the pre-determined name prefix is provided by a manufacturer of the client device.
7 . The method of claim 1 , further comprising updating a device database by adding the client device using the assigned name.
8 . The method of claim 7 , further comprising:
receiving an additional interest for discovery of other devices in the CCN;
in response to the additional interest, generating a device-list content object based on information stored in the device database; and
returning the device-list content object.
9 . The method of claim 8 , further comprising:
performing a security check to determine whether a device sending the additional interest is authorized to obtain the device-list content object; and
in response to determining that the device sending the additional interest is authorized to obtain the device-list content object, sending the device-list content object to the authorized device.
10 . A non-transitory computer-readable storage medium storing instructions that when executed by a computing device cause the computing device to perform a method for device registration and discovery in a content-centric network (CCN), the method comprising:
receiving, by a computer, an interest for registration of a client device, wherein the interest includes at least a unique identifier associated with the client device;
generating a content object in response to the interest, wherein the content object includes at least a name assigned to the client device; and
sending the content object to the client device, thereby enabling the client device to be discovered by other client devices in the CCN.
11 . The computer-readable storage medium of claim 10 , wherein the interest further includes one or more of:
a public key associated with the client device;
a device type;
a device model number; and
a device identifier in an arbitrary format.
12 . The computer-readable storage medium of claim 10 , wherein the content object further includes one or more of:
a routable name prefix assigned to the client device;
a subdirectory device-discovery namespace;
one or more namespaces for the client device to publish data under; and
a namespace for the client device to obtain a signing key.
13 . The computer-readable storage medium of claim 10 , wherein the interest has a pre-determined name prefix.
14 . The computer-readable storage medium of claim 13 , wherein the method further comprises notifying the client device of the pre-determined name prefix during an initial configuration of the client device.
15 . The computer-readable storage medium of claim 13 , wherein the pre-determined name prefix is provided by a manufacturer of the client device.
16 . The computer-readable storage medium of claim 10 , wherein the method further comprises updating a device database by adding the client device using the assigned name.
17 . The computer-readable storage medium of claim 16 , wherein the method further comprises:
receiving an additional interest for discovery of other devices in the CCN;
in response to the additional interest, generating a device-list content object based on information stored in the device database; and
returning the device-list content object.
18 . The computer-readable storage medium of claim 17 , wherein the method further comprises:
performing a security check to determine whether a device sending the additional interest is authorized to obtain the device-list content object; and
in response to determining that the device sending the additional interest is authorized to obtain the device-list content object, sending the device-list content object to the authorized device.
19 . A computer system for device registration and discovery of a content-centric network (CCN), the system comprising:
a processor; and
a storage device coupled to the processor and storing instructions which when executed by the processor cause the processor to perform a method, the method comprising:
receiving, by a computer, an interest for registration of a client device, wherein the interest includes at least a unique identifier associated with the client device;
generating a content object in response to the interest, wherein the content object includes at least a name assigned to the client device; and
sending the content object to the client device, thereby enabling the client device to be discovered by other client devices in the CCN.
20 . The system of claim 19 , wherein the interest further includes one or more of:
a public key associated with the client device;
a device type;
a device model number; and
a device identifier in an arbitrary format.
21 . The system of claim 19 , wherein the content object further includes one or more of:
a routable name prefix assigned to the client device;
a subdirectory device-discovery namespace;
one or more namespaces for the client device to publish data under; and
a namespace for the client device to obtain a signing key.
22 . The system of claim 19 , wherein the interest has a pre-determined name prefix.
23 . The system of claim 22 , wherein the method further comprises notifying the client device of the pre-determined name prefix during an initial configuration of the client device.
24 . The system of claim 22 , wherein the pre-determined name prefix is provided by a manufacturer of the client device.
25 . The system of claim 19 , wherein the method further comprises updating a device database by adding the client device using the assigned name.
26 . The system of claim 25 , wherein the method further comprises:
receiving an additional interest for discovery of other devices in the CCN;
in response to the additional interest, generating a device-list content object based on information stored in the device database; and
returning the device-list content object.
27 . The system of claim 26 , wherein the method further comprises:
performing a security check to determine whether a device sending the additional interest is authorized to obtain the device-list content object; and
in response to determining that the device sending the additional interest is authorized to obtain the device-list content object, sending the device-list content object to the authorized device.
