Abstract

Systems and methods for remote file access are disclosed. According to an embodiment, a server receives a task request from a remote client identifying a file in a local computer and adds the task request to a task queue. The server receives a poll from a local agent and responds to the poll by sending the task request to the local agent. The server receives the file and sets notification information that the request is complete. The server can include a task queue for storing the task requests and a communication stack, such as TCP/IP, for communicating with the local agent. The server can also be configured to interface with a speech module for converting text to speech and speech to text for engaging a remote client. As well, the server can include a database management system.

Claims

1. A computer implemented method for remote access to files for a server, comprising:

receiving a task request from a remote client, the task request identifying a file in a local computer;

adding the task request to a request queue;

receiving a poll from the local agent;

sending the task request stored in the task queue, responsive to the poll, to the local agent;

receiving the file at the server, responsive to the task request sent to the local agent; and

setting notification information concerning the task request, the notification information indicating that the task request is complete.

2. The method of claim 1, further comprising notifying the remote client that the task request is complete, based on the notification information.

3. The method of claim 1, further comprising receiving a poll from the remote client, the poll causing the server to check the notification information.

4. The method of claim 1, further comprising:

storing the task request from the remote client in a first portion of a server side cache; and

storing the file from the local agent in a second portion of the server side cache.

5. The method of claim 1, further comprising:

receiving an instruction from the remote client indicating how to transfer the file;

transferring the file from second portion of the server side cache to the remote client, in response to the instruction; and

removing the file from the second portion of the server side cache.

6. The method of claim 1, further comprising:

receiving an instruction from the remote client indicating where to transfer the file;

transferring the file from the second portion of the server side cache to a second remote client, identified in the instruction; and

removing the file from the second portion of the server side cache.

7. A computer readable medium including sequences of instructions for causing one or more processors to perform acts for remote file access for a server, the sequences of instructions comprising:

receiving a task request from a remote client, the task request identifying a file in a local computer;

adding the task request to a request queue;

receiving a poll from the local agent;

sending the task request stored in the task queue, responsive to the poll, to the local agent;

receiving the file at the server, responsive to the task request sent to the local agent; and

setting notification information concerning the task request, the notification information indicating that the task request is complete.

8. The computer readable medium of claim 7, the sequences of instructions further comprising notifying the remote client that the task request is complete, based on the notification information.

9. The computer readable medium of claim 8, the sequences of instructions further comprising receiving a poll from the remote client, the poll causing the server to check the notification information.

10. The computer readable medium of claim 8, the sequences of instructions further comprising:

storing the task request from the remote client in a first portion of a server side cache; and

storing the file from the local agent in a second portion of the server side cache.

11. The computer readable medium of claim 8, the sequences of instructions further comprising:

receiving an instruction from the remote client indicating how to transfer the file;

transferring the file from second portion of the server side cache to the remote client, in response to the instruction; and

removing the file from the second portion of the server side cache.

12. The computer readable medium of claim 8, the sequences of instructions further comprising:

receiving an instruction from the remote client indicating where to transfer the file;

transferring the file from the second portion of the server side cache to a second remote client, identified in the instruction; and

removing the file from the second portion of the server side cache.

13. A server comprising:

a task queue for receiving a task request from a remote client, the task request identifying a file in a local computer; and

a communication stack for receiving a poll from a local agent.

14. The server of claim 13, further configured to notify the remote client that the task request is complete, based on the notification information.

15. The server of claim 13, further configured to receive a poll from the remote client, the poll causing the server to check the notification information.

16. The server of claim 13, further configured to:

store the task request from the remote client in a first portion of a server side cache; and

store the file from the local agent in a second portion of the server side cache.

17. The server of claim 13, further configured to:

receive an instruction from the remote client indicating how to transfer the file;

transfer the file from second portion of the server side cache to the remote client, in response to the instruction; and

remove the file from the second portion of the server side cache.

18. The server of claim 13, further configured to:

receive an instruction from the remote client indicating where to transfer the file;

transfer the file from the second portion of the server side cache to a second remote client, identified in the instruction; and

remove the file from the second portion of the server side cache.

19. The server of claim 13, further comprising a database management system that holds remote client information, local agent information, and information relating users of the system.

20. The server of claim 19, communicatively coupled to a speed module for translating text from the file into speech directed to the remote client.
