Abstract

A method is provided for selecting between various communication access methods for client computers which are connected to a computer network. When a client computer attempts to load an application program, the system loader on the client computer is hooked or paused. A preset configuration may be evaluated to determine if the user will be prompted to select an access method, if a particular access method is preset, or if a rules database will be evaluated to select an access method. If a Remote Node access method is selected, the system loader is unpaused and the selected program is allowed to run on the remote user'"'"'s computer. If a Remote Control access method is selected, a remote control program is executed at the server. A load balancing algorithm may be used to determine which server will be used if a plurality of servers are available on the computer network for hosting a Remote Control session.

Claims

1. A method for selecting an access method for application programs used by a client computer which is connected to a computer network, the client computer having a system loader for loading application programs, comprising the steps of

(a) pausing the system loader before the system loader loads an application program, and

(b) selecting an access method based upon an evaluation of at least one predetermined rule,

wherein the access method may be selected based on the predetermined rule.

2. The method of claim 1 further comprising the step of un-pausing the system loader and allowing the application program to run if a remote node access method is selected.

3. The method of claim 1 further comprising the step of configuring the client computer and the computer network to run in remote control mode if a remote control access method is selected.

4. The method of claim 1 wherein the computer network comprises a server, the rule being stored on the server, further comprising the step of transmitting a signal from the client computer to the server to request evaluation of the rule.

5. The method of claim 4 wherein the signal comprises information relevant to evaluation of the rule.

6. The method of claim 4 wherein the rule is predetermined by a system administrator.

7. The method of claim 1 wherein the local area network comprises a plurality of servers for hosting remote control sessions, the method further comprising the step of applying a load balancing algorithm to select a server to host a client computer session if the access method selected requires a host server.

8. The method of claim 1 further comprising the step of examining a preset configuration, the preset configuration directing at least one of the following steps:

(a) selecting a particular access method,

(b) prompting a user to select an access method, and

(c) evaluating the rule to select the access method.

9. A method for selecting an access method for a user operating a client computer which is connected to a local area network, the client computer having an operating system with a system loader for loading application programs, comprising the steps of

(a) the user selecting an application program,

(b) hooking the system loader of the operating system before the application program is loaded, and

(c) selecting an access method based upon the evaluation of at least one predetermined rule,

wherein the user is not required to participate in the selection of the access method.

10. The method of claim 9 wherein the rule expresses a relationship with a predetermined variable.

11. The method of claim 9 further comprising the step of un-pausing the system loader and allowing the application program to run if a remote node access method is selected.

12. The method of claim 9 further comprising the step of configuring the client computer and the local area network to run in remote control mode if a remote control access method is selected.

13. The method of claim 9 wherein the local area network comprises a server, the rule being stored on the server, further comprising the step of transmitting a signal from the client computer to the server to request the evaluation of the rule.

14. The method of claim 13 wherein the signal comprises information relevant to the evaluation of the rule.

15. The method of claim 9 wherein the local area network comprises a plurality of servers for hosting remote control sessions, the method further comprising the step of applying a load balancing algorithm to select a server to host the remote control session if the remote control method is selected.

16. The method of claim 9 further comprising the step of examining a preset configuration, the preset configuration directing at least one of the following steps:

(a) selecting a particular access method,

(b) prompting a user to select an access method, and

(c) evaluating the rule to select the access method.

17. A system capable of selecting a communication access method in a network environment, comprising:

(A) a local device adapted to communicate with remote devices;

(B) at least one remote computer adapted to communicate with the local device;

(C) a communication device connected to the remote computer and the local device, the communication device being adapted to facilitate communication between the remote computer and the local device;

(D) an operating system installed on the remote computer, the operating system having a system loader adapted to load application programs on the remote computer;

(E) a client program installed on the remote computer, the client program being adapted to automatically pause the system loader before the system loader loads a an application program; and

(F) a selection program installed on the local device, the remote computer, or both, the selection program being adapted to select a communication access method for the application program to communicate with the local device.
