Abstract

A diagnostic system for a data access networked system (e.g., an Internet/Intranet access networked system) is described. The data access networked system includes a number of data service systems coupled together. Each of the data service systems is independently administrated. The diagnostic system includes a number of diagnostic modules, each running a number of diagnostic tests within one of the data service systems upon receiving a diagnostic request. The diagnostic modules also transmit the diagnostic request and diagnostic results to one another using an open standard communication protocol. The diagnostic system also includes a diagnostic terminal that is coupled to a first diagnostic module of the diagnostic modules to generate the diagnostic request to the first diagnostic module and to display the diagnostic results received from the first diagnostic module. A diagnostic system for a data service system of a data access networked system is also described.

Claims

1. A diagnostic system for a data access networked system that includes a plurality of data service systems coupled together, comprising:

(A) a plurality of diagnostic modules, each within one of the data service systems and running a number of diagnostic tests to check modules within that data service system upon receiving a diagnostic request, wherein each of the data service systems is independently administrated such that modules within each data service system cannot be directly accessed by external source and the diagnostic modules transmit diagnostic requests and diagnostic results to one another using an open standard communication protocol, wherein if a first diagnostic module in a first data service system wants to diagnose modules in a second data service system, the first diagnostic module is not allowed to directly access these modules in the second data service system and must transmit a diagnostic request, using the open standard communication protocol, to activate a second diagnostic module in the second data service system which then sends the diagnostic results of these modules back to the first diagnostic module;

(B) a diagnostic terminal coupled only to the first diagnostic module of the diagnostic modules to generate the diagnostic request to the first diagnostic module and display the diagnostic results received from the first diagnostic module via the open standard communication protocol.

2. The diagnostic system of claim 1, wherein the open standard communication protocol is a Hyper Text Transport Protocol (HTTP) used for Internet/Intranet accesses.

3. The diagnostic system of claim 2, wherein the diagnostic terminal further comprises a web browser that generates and sends the diagnostic request to the first diagnostic module using the HTTP protocol.

4. The diagnostic system of claim 3, wherein the diagnostic terminal is coupled to one of the data service system that includes the first diagnostic module.

5. The diagnostic system of claim 2, wherein each of the diagnostic modules further comprises

(a) a web server that decodes the diagnostic request received from the diagnostic terminal;

(b) a diagnostic engine that runs the diagnostic tests based on the decoded diagnostic request.

6. The diagnostic system of claim 5, wherein the diagnostic engine further comprises a plurality of test modules that perform the diagnostic tests and a main engine that validates the decoded diagnostic request and correlates test results from the test modules.

7. The diagnostic system of claim 6, wherein each of the test modules further comprises a diagnostic tester that runs a predetermined test and a test wrapper that enables the diagnostic tester and passes the test result from the tester to the main engine.

8. The diagnostic system of claim 5, wherein the diagnostic engine further comprises at least one inter-domain test module that regenerates and sends the decoded diagnostic request to other diagnostic modules using the open standard communication protocol.

9. The diagnostic system of claim 8, wherein the inter-domain test module further comprises

(I) a formatting module that formats the decoded diagnostic request in accordance with the open standard communication protocol;

(II) a caller module that sends the decoded diagnostic request to the formatting module for formatting and then sends the formatted diagnostic request to other diagnostic modules.

10. A diagnostic system for a data service system of a data access networked system, comprising:

(A) a diagnostic server within the data service system to initiate a plurality of diagnostic tests to detect faulty modules within the data service system upon receiving a diagnostic request, wherein the data service system is independently administrated such that modules of the data service system are not allowed to be directly accessed by external source and the diagnostic server is externally activated only by the diagnostic request sent to the data service system via an open standard communication protocol, wherein the diagnostic server then sends diagnostic results of the data service system back using the same open standard communication protocol;

(B) a diagnostic terminal coupled to the data service system to transmit the diagnostic request to the diagnostic server and to receive the diagnostic results from the data service system via the open standard communication protocol.

11. The diagnostic system of claim 10, wherein the open standard communication protocol is a Hyper Text Transport Protocol (HTTP) used for Internet/Intranet accesses.

12. The diagnostic system of claim 11, wherein the diagnostic terminal further comprises a web browser that generates and sends the diagnostic request to the diagnostic sever using the HTTP protocol.

13. The diagnostic system of claim 11, wherein the diagnostic server further comprises

(a) a web server that decodes the diagnostic request received from the diagnostic terminal;

(b) a diagnostic engine that runs the diagnostic tests based on the decoded diagnostic request.

14. The diagnostic system of claim 13, wherein the diagnostic engine further comprises a plurality of test modules that perform the diagnostic tests and a main engine that validates the decoded diagnostic request and correlates test results from the test modules.

15. The diagnostic system of claim 14, wherein each of the test modules further comprises a diagnostic tester that runs a predetermined test and a test wrapper that enables the diagnostic tester and passes the test result from the tester to the main engine.
