Abstract

A method for streaming software may include downloading blocks associated with a software title until an executable threshold is reached, initiating execution of the software title, and continuing to download blocks of the software title while the software title is executed. Another method for streaming software may include sending to a client data sufficient for the client to build a virtual directory structure for use in executing a software title, streaming a subset of blocks associated with the software title to the client, and streaming additional blocks associated with the software title to the client on demand. A system for streaming software may include a server computer and a client computer. The server computer may include a program database and a streaming engine. In operation the streaming engine may stream an executable streaming application from the program database to the client.

Claims

1. A method comprising:

sending a request from a client device to a streaming server to execute a streaming target program on the client device, the client device including a profile associated with the client device and the streaming target program being fully installed on a clean system and preprocessed to create an index the client device is configured to access;

using the index to present a virtual directory structure at the client device;

receiving a dependency string of the streaming target program according to the profile associated with the client device;

beginning execution of the streaming target program at the client device using the dependency string and the virtual directory structure;

receiving additional blocks of the streaming target program according to the profile associated with the client device and interaction between a user of the client device and the streaming target program;

continuing execution of the streaming target program at the client device using the additional blocks and the virtual directory structure.

2. The method of claim 1, wherein the dependency string includes executables and DLLs used in beginning execution of the streaming target program at the client device.

3. The method of claim 1, wherein the virtual directory structure includes file properties of the streaming target program in being executed on the clean system and an overall directory structure of the clean system in executing the streaming target program.

4. The method of claim 1, wherein the index includes directories and files created in executing the streaming target program as determined from executing the streaming target program on the clean system.

5. The method of claim 1, wherein the virtual directory structure includes file properties of the streaming target program in being executed on the clean system and an overall directory structure of the clean system in executing the streaming target program.

6. The method of claim 1, wherein the index includes information that can be used by a client-side file system driver to compute which block of the streaming target program to download at runtime in executing the streaming target program on the client device.

7. The method of claim 1, wherein the index includes a location of files of the streaming target program in an overall directory hierarchy.

8. The method of claim 1, wherein the index includes unique IDs assigned to files of the streaming target program, the unique IDs used by a client-side file system driver to determine when the files are needed at runtime in executing the streaming target program on the client device.

9. The method of claim 1, wherein the index includes a client version number, a software title version number, an expiration date for the index, or a program ID used in identifying the streaming target program in authenticating the client device.

10. A system comprising:

a memory storing instructions;

a client device upon executing the instructions configured to;

send a request from the client device to a streaming server to execute a streaming target program on the client device, the client device including a profile associated with the client device and the streaming target program being fully installed on a clean system and preprocessed to create an index the client device is configured to access;

access a virtual directory structure using the index;

receive a dependency string of the streaming target program according to the profile associated with the client device;

begin execution of the streaming target program at the client device using the dependency string and the virtual directory structure;

receive additional blocks of the streaming target program according to the profile associated with the client device and interaction between a user of the client device and the streaming target program;

continue execution of the streaming target program at the client device using the additional blocks and the virtual directory structure.

11. The system of claim 10, wherein the dependency string includes executables and DLLs used in beginning execution of the streaming target program at the client device.

12. The system of claim 10, wherein the virtual directory structure includes file properties of the streaming target program in being executed on the clean system and an overall directory structure of the clean system in executing the streaming target program.

13. The system of claim 10, wherein the index includes directories and files created in executing the streaming target program as determined from executing the streaming target program on the clean system.

14. The system of claim 10, wherein the virtual directory structure includes file properties of the streaming target program in being executed on the clean system and an overall directory structure of the clean system in executing the streaming target program.

15. The system of claim 10, wherein the index includes information that can be used by a client-side file system driver to compute which block of the streaming target program to download at runtime in executing the streaming target program on the client device.

16. The system of claim 10, wherein the index includes a location of files of the streaming target program in an overall directory hierarchy.

17. The system of claim 10, wherein the index includes unique IDs assigned to files of the streaming target program, the unique IDs used by a client-side file system driver to determine when the files are needed at runtime in executing the streaming target program on the client device.

18. The system of claim 10, wherein the index includes a client version number, a software title version number, an expiration date for the index, or a program ID used in identifying the streaming target program in authenticating the client device.
