Abstract

A system, computer program product and method for automatically restoring logon connectivity in a broadband network system. Upon establishing a connection between a client and Internet gateway (INTERNET GATEWAY), the status of the connection, i.e., connected or disconnected, may be checked by issuing a request to an INTERNET GATEWAY utilizing a protocol that is normally blocked when the client is disconnected. By issuing a request utilizing a protocol that is normally blocked when the client is disconnected, the status of the connection may be determined by whether the request may be serviced. If the request cannot be serviced, then a subsequent connection may be established automatically by terminating the logon procedure associated with the preceding connection, e.g., initial connection, and executing the logon procedure associated with the subsequent connection.

Claims

1. A method for automatically restoring logon connectivity in a network system comprising the steps of:

establishing a first connection between a client and an Internet gateway;

checking status of said first connection by issuing a first request to said Internet gateway to access a web server utilizing a protocol blocked under a logged off status;

determining whether said web server is accessed from said first request; and

automatically attempting to establish a second connection to said Internet gateway if said web server was not accessed from said first request.

2. The method as recited in claim 1, wherein if said web server was accessed from said first request then the method further comprises the steps of:

waiting for a first period of time; and

checking status of said first connection by issuing a second request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

3. The method as recited in claim 2, wherein upon said attempting to establish said second connection to said Internet gateway the method further comprises the step of:

waiting for a second period of time, wherein said second period of time is less than said first period of time; and

checking status of said attempted second connection by issuing a third request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

4. The method as recited in claim 1, wherein said first connection is established by a first logon procedure.

5. The method as recited in claim 4, wherein said step of attempting to establish said second connection comprises the steps of

terminating said first logon procedure;

and

executing a second logon procedure.

6. The method as recited in claim 5 further comprising the step of:

waiting for a first period of time.

7. The method as recited in claim 6 further comprising the step of:

checking status of said attempted second connection by issuing a second request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

8. The method as recited in claim 7 further comprising the step of:

determining whether said web server is accessed from said second request.

9. The method as recited in claim 8, wherein if said web server is accessed from said second request then the method further comprises the steps of:

waiting for a second period of time, wherein said first period of time is less than said second period of time; and

checking status of said attempted second connection by issuing a third request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

10. The method as recited in claim 8, wherein if said web server was not accessed from said second request then the method further comprises the step of

automatically attempting to establish a third connection to said Internet gateway.

11. The method as recited in claim 1, wherein said protocol is a HyperText Transport Protocol.

12. The method as recited in claim 1, wherein said protocol is a file transfer protocol.

13. The method as recited in claim 1, wherein said protocol is a telnet protocol.

14. A system, comprising:

a processor;

a memory unit storing a computer program operable for automatically restoring logon connectivity in a network system;

an input mechanism;

an output mechanism;

a bus system coupling the processor to the memory unit, input mechanism, and output mechanism, wherein the computer program comprises the programming steps of;

establishing a first connection between one or more clients and an Internet gateway;

checking status of said first connection by issuing a first request to said Internet gateway to access a web server utilizing a protocol blocked under a logged off status;

determining whether said web server is accessed from said first request; and

automatically attempting to establish a second connection between said one or more clients and said Internet gateway if said web server was not accessed from said first request.

15. The system as recited in claim 14, wherein if said web server was accessed from said first request then the computer program further comprises the programming steps of

waiting for a first period of time;

and

checking status of said first connection by issuing a second request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

16. The system as recited in claim 15, wherein upon said attempting to establish said second connection between said one or more clients and said Internet gateway the computer program further comprises the programming steps of:

waiting for a second period of time, wherein said second period of time is less than said first period of time; and

checking status of said attempted second connection by issuing a third request to said Internet gateway to access said web server utilizing said protocol blocked under said logged off status.

17. The system as recited in claim 14, wherein said first connection is established by a first logon procedure.

18. The system as recited in claim 17, wherein said step of attempting to establish said second connection comprises the programming steps of:
