Abstract

A computer-implemented method includes: receiving an interest of an object in a network; obtaining a stack requirement for a protocol stack, wherein the stack requirement specifies at least a functionality for a stack component; selecting the stack component, based on the functionality and at least a name prefix of the interest or the object; and instantiating the stack component in the protocol stack.

Claims

1. A computer-implemented method, comprising:

receiving an interest of an object in a network;

obtaining a stack requirement for a protocol stack, wherein the stack requirement specifies at least a functionality for a stack component;

selecting the stack component for the protocol stack, based on the functionality and at least a name prefix of the interest or the object;

instantiating the stack component in the protocol stack; and

processing a flow of network packets using the protocol stack.

2. The method of claim 1, wherein the stack component is selected based on a name of the interest or the object.

3. The method of claim 1, wherein the selecting includes:

determining, from the stack requirement, a component requirement;

determining, from a component repository, a set of components that satisfies the component requirement; and

selecting, from the set of components, the stack component, which is compatible with other components in the protocol stack.

4. The method of claim 1, further comprising:

searching for the stack component in a local repository; and

responsive to determining that the stack component is not available in the local repository, obtaining the stack component from a remote repository.

5. The method of claim 4, wherein the remote repository includes one or more of:

a component cache;

a component storage server;

or

a component marketplace.

6. The method of claim 1, further comprising:

determining that an updated version of the stack component exists;

determining a protocol stack in which the stack component is instantiated; and

replacing an instantiation of the stack component with an instantiation of the updated version of the stack component.

7. The method of claim 6, further comprising:

analyzing the updated version of the stack component to obtain a stack requirement; and

responsive to determining that the stack requirement of the stack component has changed, updating an implementation of the protocol stack to satisfy a new stack requirement.

8. 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 an interest of an object in a network;

obtaining a stack requirement for a protocol stack, wherein the stack requirement specifies at least a functionality for a stack component;

selecting the stack component for the protocol stack, based on the functionality and at least a name prefix of the interest or the object;

instantiating the stack component in the protocol stack; and

processing a flow of network packets using the protocol stack.

9. The non-transitory computer-readable storage medium of claim 8, wherein the stack component is selected, based on a name of the interest or the object.

10. The non-transitory computer-readable storage medium of claim 8, wherein the selecting involves:

determining, from the stack requirement, a component requirement;

determining, from a component repository, a set of components that satisfies the component requirement; and

selecting, from the set of components, the stack component, which is compatible with other components in the protocol stack.

11. The non-transitory computer-readable storage medium of claim 8, further comprising:

searching for the stack component in a local repository; and

responsive to determining that the stack component is not available in the local repository, obtaining the stack component from a remote repository.

12. The non-transitory computer-readable storage medium of claim 11, wherein the remote repository includes one or more of:

a component cache;

a component storage server;

or

a component marketplace.

13. The non-transitory computer-readable storage medium of claim 8, further comprising:

determining that an updated version of the stack component exists;

determining a protocol stack in which the stack component is instantiated; and

replacing an instantiation of the stack component with an instantiation of the updated version of the stack component.

14. The non-transitory computer-readable storage medium of claim 13, further comprising:

analyzing the updated version of the stack component to obtain a stack requirement; and

responsive to determining that the stack requirement of the stack component has changed, updating an implementation of the protocol stack to satisfy a new stack requirement.

15. An apparatus comprising:

a communication interface;

a processor; and

a memory configured to store instructions executable by the processor,

wherein the processor is configured to;

receive an interest of an object in a network;

obtaining a stack requirement for a protocol stack, wherein the stack requirement specifies at least a functionality for a stack component;

select the stack component for the protocol stack, based on the functionality and at least a name prefix of the interest or the object;

instantiate the stack component in the protocol stack; and

process a flow of network packets using the protocol stack.

16. The apparatus of claim 15, wherein the processor is further configured to:

determine, from the stack requirement, a component requirement;

determine, from a component repository, a set of components that satisfies the component requirement; and

select, from the set of components, the stack component, which is compatible with other components in the protocol stack.

17. The apparatus of claim 15, wherein the processor is further configured to:

search for the stack component in a local repository; and

responsive to determining that the stack component is not available in the local repository, obtain the stack component from a remote repository.

18. The apparatus of claim 17, wherein the remote repository includes one or more of:

a component cache;

a component storage server;

or

a component marketplace.

19. The apparatus of claim 15, the processor is further configured to:

determine that an updated version of the stack component exists;

determine a protocol stack in which the stack component is instantiated; and

replace an instantiation of the stack component with an instantiation of the updated version of the stack component.

20. The apparatus of claim 19, the processor is further configured to:

analyze the updated version of the stack component to obtain a stack requirement; and

responsive to determining that the stack requirement of the stack component has changed, update an implementation of the protocol stack to satisfy a new stack requirement.
