Abstract

A system for enabling components on arbitrary networks to communicate includes a plurality of arbitrary components, such as computers, servers, laptops, facsimile machines, copier machines and cellular telephones, including applications operating on those components, such as word processing or data base applications, connected together by one or more networks that may use the same or different protocols. A method includes a first component, such as a computer, obtaining aggregate objects from other components, such as a laptop or server. Each of the aggregate objects are associated with discovered component objects of the other components, such as the laptop or server. The first component selects at least one of the components associated with the aggregate objects, and invokes universal interfaces associated with the selected arbitrary components to communicate with other arbitrary components.

Claims

1. A method comprising:

obtaining a first aggregate object from a first component of a plurality of components, the obtained first aggregate object associated with at least one of the components;

selecting at least one of the components associated with the first aggregate object; and

invoking at least one of a plurality of universal interfaces associated with the at least one selected component to communicate with at least one other of the components.

2. The method as set forth in claim 1 wherein at least one of the components is on a first network.

3. The method as set forth in claim 2 further comprising publishing the at least one component onto a second network.

4. The method as set forth in claim 1 further comprising associating a wrapper proxy object with at least one component in the first aggregate object, the wrapper proxy object having at least one mobile code instruction, which when executed by at least one legacy component, enables the legacy component to communicate with the at least one component.

5. The method as set forth in claim 1 further comprising associating a wrapper proxy object with at least one component in the first aggregate object, the at least one component being on a first network, the wrapper proxy object having at least one mobile code instruction, which when executed by at least one other component on a second network, enables the at least one other component to communicate with the at least one component on the first network.

6. The method as set forth in claim 1 further comprising:

obtaining a second aggregate object from a second component of the plurality of components, the obtained second aggregate object associated with at least one of the components;

selecting at least one of the components associated with the second aggregate object; and

invoking at least one of a plurality of universal interfaces associated with the at least one selected component associated with the second aggregate object to communicate with the at least one other of the components.

7. The method as set forth in claim 1 wherein obtaining a first aggregate object further comprises using a first discovery protocol to locate the first component.

8. The method as set forth in claim 7 further comprising obtaining a second aggregate object from a second component using a second discovery protocol.

9. The method as set forth in claim 1 further comprising querying the obtained first aggregate object to locate at least one component matching at least one query constraint.

10. The method as set forth in claim 9 wherein querying the obtained first aggregate object is performed recursively.

11. The method as set forth in claim 9 wherein the at least one query constraint in a query is modified to include at least one updated constraint.

12. The method as set forth in claim 1 further comprising sending a query object to at least one of the components, the query object having at least one mobile code instruction, which when executed by the at least one component, enables the component to understand and execute a first type of query operator.

13. A computer-readable medium having stored thereon instructions, which when executed by at least one processor, causes the processor to perform:

obtaining a second aggregate object from a second component of the plurality of components, the obtained second aggregate object associated with at least one of the components;

selecting at least one of the components associated with the second aggregate object; and

invoking at least one of a plurality of universal interfaces associated with the at least one selected component associated with the second aggregate object to communicate with the at least one other of the components.

14. The medium as set forth in claim 13 wherein at least one of the components is on a first network.

15. The medium as set forth in claim 14 further comprising publishing the at least one component onto a second network.

16. The medium as set forth in claim 13 further comprising associating a wrapper proxy object with at least one component in the first aggregate object, the wrapper proxy object having at least one mobile code instruction, which when executed by at least one legacy component, enables the legacy component to communicate with the at least one component.

17. The medium as set forth in claim 13 further comprising associating a wrapper proxy object with at least one component in the first aggregate object, the at least one component being on a first network, the wrapper proxy object having at least one mobile code instruction, which when executed by at least one other component on a second network, enables the at least one other component to communicate with the at least one component on the first network.

18. The medium as set forth in claim 13 further comprising:

obtaining a second aggregate object from a second component, the obtained second aggregate object associated with the at least one component;

selecting at least one of the components associated with the second aggregate object; and

invoking at least one of a plurality of universal interfaces associated with the at least one selected component associated with the second aggregate object to communicate with at least one other of the components.

19. The medium as set forth in claim 13 wherein obtaining a first aggregate object further comprises using a first discovery protocol to locate the first component.

20. The medium as set forth in claim 19 further comprising obtaining a second aggregate object from a second component using a second discovery protocol.

21. The medium as set forth in claim 13 further comprising querying the obtained first aggregate object to locate at least one component matching at least one query constraint.

22. The medium as set forth in claim 21 wherein querying the obtained first aggregate object is performed recursively.

23. The medium as set forth in claim 21 wherein at least one of the at least one query constraint in a query is modified to include at least one updated constraint.

24. The medium as set forth in claim 13 further comprising sending a query object to at least one of the components, the query object having at least one mobile code instruction, which when executed by the at least one component, enables the component to understand and execute a first type of query operator.

25. A system comprising:

a first component with a first aggregate object associated with at least one of a plurality of components, the at least one component associated with at least one universal interface, the universal interface having at least one instruction which when executed enables the first component to communicate with the at least one component.
