Abstract

A system for detecting and correcting an error in session between a client and a host over a network. When the system receives an indication of an error in a session, the system determines an error correction modification to the configuration of the session to correct the error. The system then implements the error correction modification to the configuration of the session and continues the session.

Claims

1. A method for correcting errors in a session between a client and a provider over a connection in a network comprising:

receiving an indication of an error in said session;

reading a error correction modification to a configuration of said session from a memory responsive to receiving said indication of said error;

implementing said error correction modification in said configuration of said session responsive to a determination of error correction modification; and

continuing said session responsive to implementation of said error correction modification in said configuration.

2. The method of claim 1 wherein said step of reading said error correction modification comprises:

determining said error indicated by said indication;

determining said error correction modification based upon said error; and

reading said error correction modification determined from said error from said memory.

3. The method of claim 1 wherein said step of reading said error correction modification based upon said error comprises:

determining said error correction modification based upon an identification of said client.

4. The method of claim 3 wherein said indication of said error includes said identification of said user.

5. The method of claim 1 wherein said step of determining said error correction modification further comprises:

determining said error correction modification based upon a Quality of Service provided said client; and

reading said error correction modification from said memory responsive to said determination.

6. The method of claim 5 wherein said indication of said error includes said Quality of Service for said client.

7. The method of claim 1 wherein said error correction modification stored in said memory for said error is a default error correction modification.

8. The method of claim 7 further comprising:

receiving an input of a user error correction modification for said error;

storing said user error correction modification for said error in said memory; and

wherein said step of determining selects said user error correction modification for said error.

9. A computer readable medium carrying one or more instructions for correcting an error in a session over a network, the one more instructions including instructions which executed by one or more processors, cause the one or more processors to perform the method comprising:

receiving an indication of an error in said session;

reading a error correction modification to a configuration of said session from a memory responsive to receiving said indication of said error;

implementing said error correction modification in said configuration of said session responsive to a determination of error correction modification; and

continuing said session responsive to implementation of said error correction modification in said configuration.

10. The method of claim 9 wherein said step of reading said error correction modification comprises:

determining said error indicated by said indication;

determining said error correction modification based upon said error; and

reading said error correction modification determined from said error from said memory.

11. The method of claim 9 wherein said step of reading said error correction modification based upon said error comprises:

determining said error correction modification based upon an identification of said client.

12. The method of claim 11 wherein said indication of said error includes said identification of said user.

13. The method of claim 9 wherein said step of determining said error correction modification further comprises:

determining said error correction modification based upon a Quality of Service provided said client; and

reading said error correction modification from said memory responsive to said determination.

14. The method of claim 13 wherein said indication of said error includes said Quality of Service for said client.

15. The method of claim 9 wherein said error correction modification stored in said memory for said error is a default error correction modification.

16. The method of claim 15 further comprising:

receiving an input of a user error correction modification for said error;

storing said user error correction modification for said error in said memory; and

wherein said step of determining selects said user error correction modification for said error.

17. A router that provides a session to a client over the network having a memory that stores instructions for correcting an error detected in said session wherein said instructions configure said router to:

receive an indication of an error in said session;

read a error correction modification to a configuration of said session from a memory responsive to receiving said indication of said error;

implement said error correction modification in said configuration of said session responsive to a determination of error correction modification; and

continue said session responsive to implementation of said error correction modification in said configuration.

18. The router of claim 17 wherein said instructions for the step of reading said error correction modification configure said router to:

determine said error indicated by said indication;

determine said error correction modification based upon said error; and

read said error correction modification determined from said error from said memory.

19. The router of claim 17 wherein said instructions for said step of reading said error correction modification based upon said error configure said router to:

determine said error correction modification based upon an identification of said client.

20. The router of claim 19 wherein said indication of said error includes said identification of said user.

21. The router of claim 17 wherein said instructions for said step of determining said error correction modification configure said router to:

determine said error correction modification based upon a Quality of Service provided said client; and

read said error correction modification from said memory responsive to said determination.

22. The router of claim 21 wherein said indication of said error includes said Quality of Service for said client.

23. The router of claim 17 wherein said error correction modification stored in said memory for said error is a default error correction modification.

24. The router of claim 23 wherein said instructions further configure said router to:

receive an input of a user error correction modification for said error;

store said user error correction modification for said error in said memory; and

wherein said step of determining selects said user error correction modification for said error.
