Abstract

A method for sharing data includes creating a socket serviced by a server application executing within a central operating system environment and creating another socket serviced by a client application executing within a virtualized operating system environment. The central operating system environment and virtualized operating system environment run on a single computer and are separated by a secure boundary. The central operating system environment has administrative control over the virtualized operating system environment. The method also includes establishing a communication link across the secure boundary and between the sockets, requesting at least one element of a server array existing in a memory space of the server application and passing the at least one element to the client application via the communication link to mirror the server array into a memory space of the client application.

Claims

1. A method for sharing data comprising:

creating a socket serviced by a server application executing within a central operating system environment;

creating another socket serviced by a client application executing within a virtualized operating system environment, the central operating system environment and virtualized operating system environment running on a single computer and separated by a secure boundary, the central operating system environment having administrative control over the virtualized operating system environment;

establishing a communication link across the secure boundary and between the sockets;

requesting at least one element of a server array existing in a memory space of the server application; and

passing the at least one element to the client application via the communication link to mirror the server array into a memory space of the client application.

2. The method of claim 1 wherein the sockets comprise network sockets.

3. The method of claim 1 wherein the sockets comprise inter-process communication sockets.

4. The method of claim 1 wherein the communication link comprises a network connection.

5. The method of claim 1 wherein the communication link comprises an inter-process communication connection.

6. A method for sharing data comprising:

creating a socket serviced by a server application executing within a central operating system environment;

creating another socket serviced by a client application executing within a virtualized operating system environment, the central operating system environment and virtualized operating system environment running on a single computer and separated by a secure boundary, the central operating system environment having administrative control over the virtualized operating system environment;

establishing a communication link across the secure boundary and between the sockets; and

passing at least one changed element of a server array existing in a memory space of the sever application to the client application via the communication link to mirror the server array into a memory space of the client application.

7. The method of claim 6 wherein the sockets comprise network sockets.

8. The method of claim 6 wherein the sockets comprise inter-process communication sockets.

9. The method of claim 6 wherein the communication link comprises a network connection.

10. The method of claim 6 wherein the communication link comprises an inter-process communication connection.

11. A method for sharing data between a server application executing within a central operating system environment and a client application executing within a virtualized operating system environment, the central operating system environment and virtualized operating system environment running on a single computer and separated by a secure boundary, the central operating system environment having administrative control over the virtualized operating system environment, the method comprising:

creating a socket serviced by the server application;

creating another socket serviced by the client application;

establishing a communication link across the secure boundary and between the sockets;

requesting at least one element of an array existing in a memory space of the server application; and

passing the at least one element to the client application via the communication link to mirror the array in a memory space of the client application.

12. The method of claim 11 wherein the sockets comprise network sockets.

13. The method of claim 11 wherein the sockets comprise inter-process communication sockets.

14. The method of claim 11 wherein the communication link comprises a network connection.

15. The method of claim 11 wherein the communication link comprises an inter-process communication connection.
