Abstract

Systems, methods and computer program products for aliasing of named data objects (in named data networks) and entities for named data networks (e.g., named graphs for named data networks). In various examples, aliasing of named data objects may be implemented in one or more named data networks in the form of systems, methods and/or algorithms. In other examples, named graphs may be implemented in one or more named data networks in the form of systems, methods and/or algorithms.

First claim

What is claimed is:

1. A method implemented in a computer system for aliasing data objects in a named data network, the named data network including a plurality of routers for routing the data objects across the named data network, wherein at least a first one of the data objects is associated with at least a first alias, the method comprising:
detecting by a first one of the routers a content of at least one named data object request for the first data object and a content of at least one response to the named data object request, wherein the content of the at least one request comprises a name and the content of the at least one response comprises a semantic representation of the name; and
implicitly learning by the first router the first alias based at least in part upon the detected content of at least one of the request and the response;
wherein the implicitly learning is based upon a query normalization associated with the detected content;
wherein the query normalization normalizes different types of queries into standard data names; and
wherein the standard data names are specified by a naming structure utilized by the plurality of routers of the named data network.

2. The method of claim 1 , further comprising associating the first data object with the first alias.

3. The method of claim 2 , wherein the associating comprises registration of the first alias with a name management server.

4. The method of claim 2 , further comprising propagating the first alias to at least a second one of the routers.

5. The method of claim 1 , wherein the request and the response are routed through the first router.

6. The method of claim 1 , wherein the query normalization uses boolean expression simplification.

7. The method of claim 1 , wherein the naming structure comprises attributes of the data objects.

8. A method implemented in a computer system for aliasing data objects in a named data network, the named data network including a plurality of routers for routing the data objects across the named data network, wherein at least a first one of the data objects is associated with at least a first alias, the method comprising:
detecting by a first one of the routers a content of at least one named data object request for the first data object and a content of at least one response to the named data object request, wherein the content of the at least one response comprises a name and the content of the at least one request comprises a semantic representation of the name; and
implicitly learning by the first router the first alias based at least in part upon the detected content of at least one of the request and the response;
wherein the implicitly learning is based upon a query normalization associated with the detected content;
wherein the query normalization normalizes different types of queries into standard data names; and
wherein the standard data names are specified by a naming structure utilized by the plurality of routers of the named data network.

9. The method of claim 8 , further comprising associating the first data object with the first alias.

10. The method of claim 9 , wherein the associating comprises registration of the first alias with a name management server.

11. The method of claim 9 , further comprising propagating the first alias to at least a second one of the routers.

12. The method of claim 8 , wherein the request and the response are routed through the first router.

13. The method of claim 8 , wherein the query normalization uses boolean expression simplification.

14. The method of claim 8 , wherein the naming structure comprises attributes of the data objects.
