Abstract

In a system that partitions an application program into page segments, a minimal portion of the application program is installed on a client system. The client prefetches page segments from the application server or the application server pushes additional page segments to the client. The application server begins streaming the requested page segments to the client when it receives a valid access token from the client. The client performs server load balancing across a plurality of application servers. If the client observes a non-response or slow response condition from an application server or license server, it switches to another application or license server.

Claims

1. A method comprising:

receiving, by a server system including a plurality of application service providers'"'"' servers, a request to stream a program from the server system to a client system;

performing load balancing across the server system, further comprising;

maintaining a server list that includes the plurality of application service providers'"'"' servers ordered according to response times of the plurality of application service providers'"'"' servers for fulfilling responses to client requests;

sending the server list to the client system, the server list used by the client system to determine to which of the plurality of application service providers'"'"' servers to send requests;

receiving, by at least one application service provider'"'"'s server of the plurality of application service providers'"'"' servers based on the server list, a plurality of requests, generated by the client system, to retrieve a plurality of program page segments of the program that are stored on the plurality of application service providers'"'"' servers, the plurality of requests forming a pattern of page segment requests;

retrieving the plurality of program page segments;

sending the plurality of program page segments to the client system;

retrieving, based on the pattern of page segment requests, a specific program page segment, stored on the at least one application service provider'"'"'s server of the plurality of application service providers'"'"' servers, to be sent to the client system.

2. The method of claim 1, wherein the specific program page segment is further retrieved based on program locality or program history.

3. The method of claim 1, further comprising:

generating, by the client system, a request to retrieve the specific program page segment based on the pattern of page segment requests;

retrieving the specific program page segment based on the request to retrieve the specific program page segment.

4. The method of claim 3, wherein the client system receives the pattern of page segment requests from the server system.

5. The method of claim 1, further comprising:

generating, by the server system, information of the specific program page segment to retrieve based on the pattern of page segment requests;

retrieving the specific program page segment based on the information of the specific program page segment.

6. The method of claim 1, wherein the specific program page segment is further retrieved based on fetching patterns of the client system in receiving previously streamed programs.

7. The method of claim 1, further comprising determining, by the server system, based on the pattern of page segment requests, whether the client system is copying an executable file of the program or executing the executable file of the program.

8. The method of claim 7, further comprising avoiding sending the specific program page segment to the client system when it is determined that the client system is copying the executable file.

9. The method of claim 1, further comprising:

determining whether a cache of the client system contains the specific program page segment;

avoiding sending the specific program page segment to the client system, when the cache of the client system contains the specific program page segment.

10. A system comprising:

a server side monitor configured to perform load balancing across a plurality of application service providers'"'"' servers by maintaining a server list that includes the plurality of application service providers'"'"' servers ordered according to response times of the plurality of application service providers'"'"' servers for fulfilling responses to client requests, the server list used by a client system to determine to which of the plurality of application service providers'"'"' servers to send requests;

a server system, including the plurality of application service providers'"'"' servers, configured to;

send the server list to the client system, the server list used by the client system to determine to which of the plurality of application service providers'"'"' servers to send requests;

receive from the client system, according to the server list, a plurality of requests to retrieve a plurality of program page segments of a program stored on the plurality of application service providers'"'"' servers, the plurality of requests forming a pattern of page segment requests;

retrieve the plurality of program page segments;

send the plurality of program page segments to the client system;

retrieve, based on the pattern of page segment requests, a specific program page segment, stored on at least one application service provider'"'"'s server of the plurality of application service providers'"'"' servers, to be sent to the client system.

11. The system of claim 10, wherein the server system is further configured to retrieve the specific program page segment based on program locality or program history.

12. The system of claim 10, wherein:

the client system is further configured to generate a request to retrieve the specific program page segment based on the pattern of page segment requests;

the server system is further configured to retrieve the specific program page segment based on the request to retrieve the specific program page segment that is generated by the client system.

13. The system of claim 12, wherein the client system receives the pattern of page segment requests from the server system.

14. The system of claim 10, wherein the server system is further configured to:

generate information of the specific program page segment to retrieve based on the pattern of page segment requests;

retrieve the specific program page segment based on the information of the specific program page segment.

15. The system of claim 10, wherein the server system is further configured to retrieve the specific program page segment based on fetching patterns of the client system in receiving previously streamed programs.

16. The system of claim 10, wherein the server system is further configured to determine whether the client system is copying an executable file of the program or executing the executable file of the program, based on the pattern of page segment requests.

17. The system of claim 16, wherein the server system is further configured to avoid sending the specific program page segment to the client system when it is determined that the client system is copying the executable file.

18. The system of claim 10, wherein the server system is further configured to:

determine whether a cache of the client system contains the specific program page segment;

avoid sending the specific program page segment to the client system, when the cache of the client system contains the specific program page segment.

19. A system comprising:

means for receiving a request to stream a program from a server system, including a plurality of application service providers'"'"' servers, to a client system;

means for performing load balancing across the server system, further comprising;

means for maintaining a server list that includes the plurality of application service providers'"'"' servers ordered according to response times of the plurality of application service providers'"'"' servers for fulfilling responses to client requests;

means for sending the server list to the client system, the server list used by the client system to determine to which of the plurality of application service providers'"'"' servers to send requests;

means for receiving, by at least one application service provider'"'"'s server of the plurality of application service providers'"'"' servers based on the server list, a plurality of requests, generated by the client system, to retrieve a plurality of program page segments of the program that are stored on the plurality of application service providers'"'"' servers, the plurality of requests forming a pattern of page segment requests;

means for retrieving the plurality of program page segments;

means for sending the plurality of program page segments to the client system;

means for retrieving, based on the pattern of page segment requests, a specific program page segment, stored on the at least one application service provider'"'"'s server of the plurality of application service providers'"'"' servers, to be sent to the client system.
