Abstract

Systems and methodologies that facilitate a unification of bus protocols and networks via an abstraction system that can bind device models and higher level protocols to multiple bus implementations. Such abstraction system can provide a common language among buses for message transfers according to priority—e.g., semantics provided for a messaging transport component for control messages, a streaming component for high priority, and a bulk transfer component for low priority. In addition, a discovery component can identify devices on a bus or network, with an association component for determining a trust established therebetween and authenticating the devices or services.

Claims

1. A system that facilitates unification of bus protocols or networks comprising:

an abstraction system that binds device models and higher level protocols to multiple bus implementations or networks, the abstraction system comprising;

a discovery component that provides a signaling mechanism for the devices to discover each other; and

a messaging transport component that transport control messages for control of the devices.

2. The system of claim 1, the abstraction system further comprises an association component that at least one of facilitates determination of a trust established among the devices and authenticates the devices or services by employing credentials previously established.

3. The system of claim 1, the abstraction system further comprises a streaming component that facilitates delivery of time sensitive information among the devices.

4. The system of claim 1, the abstraction system further comprises a bulk transfer component that facilitates delivery of low priority items.

5. The system of claim 1, the abstraction system enables an application unfamiliar with a bus to employ the bus.

6. The system of claim 1, the bus abstraction system supplies a single application program interface over a plurality of different buses.

7. The system of claim 1, the bus abstraction system facilitates sharing of device class support among protocol buses and internet protocol.

8. The system of claim 1, further comprising an adaptation component as part of a bus, the adaptation component interacts with the abstraction system.

9. The system of claim 1, the bus abstraction system re-uses device models across multiple bus technologies.

10. A method of unifying bus protocols, comprising:

binding device models and higher level protocols to multiple bus implementations or networks via an abstraction system, and

discovering a device that a message thereto is to be transferred.

11. The method of claim 10 further comprising employing a streaming component for transfer of time sensitive information.

12. The method of claim 10 further comprising employing a bulk transfer component for transfer of the message.

13. The method of claim 10 further comprising transferring the message in an at least one of an asynchronous and isochronous manner.

14. A computer readable medium having stored thereon computer executable instructions for carrying out the method of claim 10.

15. A computer-readable medium having stored thereon a data structure comprising:

a computer executable component that binds device models and higher level protocols to a plurality of buses with different bus technologies, to enable applications unfamiliar with specifics of the different bus technologies to use the plurality of buses, the computer executable component comprising a further computer executable component that provides a signaling mechanism for the applications and devices to discover each other on the plurality of buses.

16. The computer-readable medium of claim 15, the computer executable component comprising an additional computer executable component that facilitates determination of a trust established among the devices.

17. The computer-readable medium of claim 15, the computer executable component comprising another computer executable component that facilitates delivery of time sensitive information among the devices.

18. The computer-readable medium of claim 15, the computer executable component facilitates sharing of device class support among protocol buses and internet protocol.

19. The computer-readable medium of claim 15, the computer executable component re-uses device models across multiple bus technologies.

20. The computer-readable medium of claim 15, the computer executable component with an addressing scheme that provides a standard way for applications to refer to devices on the plurality of buses.
