Abstract

Among other things, in a network, a mechanism enables a resource that has a pre-assigned unique identifier and is not otherwise capable itself of being accessible on the network, to maintain a resolution record for the resource in an identifier resolution mechanism of the network where the resolution record associating the identifier with an address or other information useful in enabling the accessibility of the resource on the network through the mechanism.

Claims

1. A system comprising

in one or more networks, a mechanism configured to automatically generate unique, persistent identifiers for resources embedded in, associated with or running on devices or other computational facilities that are to be accessible on the network and,

to automatically maintain identifier records for these resources in an identifier resolution system, each of the records associating one of the identifiers with a network address or other information useful in enabling network connectivity or other accessibility of the resources on the network.

2. The system of claim 1 in which the mechanism encapsulates and forwards information to and from one or more devices or other computational facilities and the Internet.

3. The system of claim 1 or 2 in which the mechanisms create or obtain identifier information via a monitor capability.

4. The system of claim 3 in which the information obtained is verified.

5. The system of claim 3 or 4 in which one or more mechanisms provide updating information to an identifier resolution system.

6. The system of claim 5 in which the mechanism provides extensible authentication and authorization capabilities to perform the updating function securely.

7. A method for discovering the presence of devices or other computational facilities along with their network addresses whereby network-independent unique identifiers are generated for such computational facility by a mechanism based on local information provided by the facility and where the network address is updated in a resolution system accessible by other such mechanisms.

8. The method of claim 7 in which the method includes a discovery capability for services, processes, applications or other resources embedded in, associated with or running on a computational facility.

9. The method of claim 8 in which access to specific discovered resources is implemented.

10. The method of claim 9 in which authorizations to access such resources are verified.

11. The method of claim 7 in which computational facilities are handed over to other such mechanisms once the facility has moved.

12. The method of claim 8 in which a maintenance protocol is run that enables automatic state and resource update.

13. The method of claim 8 in which the mechanism runs a monitor capability.

14. A system comprising

in a network, a mechanism configured to enable a resource that has a pre-assigned unique identifier and is not otherwise capable itself of being accessible on the network, to maintain a resolution record for the resource in an identifier resolution mechanism of the network where the resolution record associating the identifier with an address or other information useful in enabling the accessibility of the resource on the network through the mechanism.

15. A method comprising

automatically discovering the presence and network addresses of resources on a network,

automatically generating network-independent unique identifiers for the resources based on local information provided by the resources, and

updating the network addresses in an identifier resolution system that is accessible across the network.
