Abstract

An identity management and initialization scheme, along with a naming scheme for a transport stack and its components, facilitates directly addressing each component in the transport stack. During operation, the system receives, by a forwarder, a packet that corresponds to an interest, where the interest includes a name. In response to determining that the interest is destined for a component of a stack of communication modules, the forwarder sends the interest to the destined component based on the name for the interest, where the stack does not require a respective communication module to communicate only with a layer above or below thereof. In response to determining that the interest is not destined for a component of the stack, the forwarder sends the interest to a network element based on the name for the interest. This facilitates directly addressing individual components of the stack.

Claims

1. A computer-implemented method, comprising:

receiving, by a forwarder executed by a hardware processor in a computer network, a packet that corresponds to an interest, wherein the interest includes a name that is location independent;

in response to determining, with the processor, that the interest is destined for a component of a stack of communication modules that includes a plurality of components, sending the interest to the destined component based on the name for the interest without passing through one or more other components of the stack, wherein the stack does not require a respective communication module to communicate only with a layer above or below thereof; and

in response to determining, with the processor, that the interest is not destined for any of the components of the stack, sending the interest to a network element based on the name for the interest,

thereby facilitating directly addressing individual components of the stack.

2. The method of claim 1, wherein the name for the interest includes one or more of:

a name for the stack;

a name for the forwarder associated with a corresponding portal instance;

a name for a component of the stack;

or

a command associated with a component of the stack.

3. The method of claim 1, wherein a name for a component of the stack is based on one or more of:

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 HSVLI is applicable in a portal instance corresponding to the stack;

a flat name that does not indicate any hierarchy;

a role of the component of the stack;

or

a unique identifier which is specific to the component of the stack.

4. The method of claim 1, wherein the interest includes a payload which includes a command associated with a component identified by the name for the interest.

5. The method of claim 1, wherein sending the interest to the destined component further comprises:

sending a message included in the interest to the destined component via a message delivery system based on the name for the interest.

6. The method of claim 1, further comprising:

receiving, from an application, a request to create a portal instance associated with the stack;

creating, with the processor, the portal instance based on application information included in the request; and

returning the portal instance to the application, wherein the portal instance indicates the stack, the forwarder associated with the stack, and each component of the stack.

7. The method of claim 6, wherein the application information includes one or more of:

a name for the portal instance;

or

a nonce for the portal instance.

8. The method of claim 6, wherein creating the portal instance is further based on an identity and a private key of a creator of the portal instance, further comprising:

storing the private key of the creator in a verifier component of the stack.

9. 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, in a computer network, a packet that corresponds to an interest, wherein the interest includes a name that is location independent;

in response to determining that the interest is destined for a component of a stack of communication modules that includes a plurality of components, sending the interest to the destined component based on the name for the interest without passing through one or more other components of the stack, wherein the stack does not require a respective communication module to communicate only with a layer above or below thereof; and

in response to determining that the interest is not destined for any of the components of the stack, sending the interest to a network element based on the name for the interest,

thereby facilitating directly addressing individual components of the stack.

10. The storage medium of claim 9, wherein the name for the interest includes one or more of:

a name for the stack;

a name for the forwarder associated with a corresponding portal instance;

a name for a component of the stack;

or

a command associated with a component of the stack.

11. The storage medium of claim 9, wherein a name for a component of the stack is based on one or more of:

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 HSVLI is applicable in a portal instance corresponding to the stack;

a flat name that does not indicate any hierarchy;

a role of the component of the stack;

or

a unique identifier which is specific to the component of the stack.

12. The storage medium of claim 9, wherein the interest includes a payload which includes a command associated with a component identified by the name for the interest.

13. The storage medium of claim 9, wherein sending the interest to the destined component further comprises:

sending a message included in the interest to the destined component via a message delivery system based on the name for the interest.

14. The storage medium of claim 9, wherein the method further comprises:

receiving, from an application, a request to create a portal instance associated with the stack;

creating the portal instance based on application information included in the request; and

returning the portal instance to the application, wherein the portal instance indicates the stack, the forwarder associated with the stack, and each component of the stack.

15. The storage medium of claim 14, wherein the application information includes one or more of:

a name for the portal instance;

or

a nonce for the portal instance.

16. The storage medium of claim 14, wherein creating the portal instance is further based on an identity and a private key of a creator of the portal instance, and wherein the method further comprises:

storing the private key of the creator in a verifier component of the stack.

17. A computer system for facilitating forwarding of packets, the system comprising:

a processor; and

a storage device storing instructions that when executed by the processor cause the processor to perform a method, the method comprising;

receiving, in a computer network, a packet that corresponds to an interest, wherein the interest includes a name that is location independent;
