Abstract
Abstract An expert system for proactively and reactively diagnosing data communication networks. The expert system operates according to a landmark data abstraction paradigm and a hypothesis and verification process. The expert system provides for operator interaction and control. The expert system includes a black board (202), modules (214) for processing questions, a facilitator (208), and a user interface (250). The expert system also includes a knowledge base (236) having forward rules for hypothesizing network problems and backward rules for verifying the hypothesized network problems.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
An expert system (102) for diagnosing data communication networks (142), the expert system (102) comprising: (1) a communication medium (202) for exchanging questions within said expert system; (2) one or more modules (214) for processing said questions; (3) means (208) for selecting said modules to process said questions; and (4) means (250) for providing operator interaction and control of said processing.
Claim 2
Dependent Claim
46 words
The expert system (102) of claim 1, further comprising: (5) logging means (106) having: (a) means for receiving said questions related to proactive diagnosis; (b) means for receiving said questions related to reactive diagnosis; and (c) means for transferring said received questions to said communication medium.
Claim 3
Dependent Claim
28 words
The expert system (102) of claim 2, further comprising: (6) means for initiating proactive diagnosis of said data communication networks by transferring proactive questions to said logging means.
Claim 4
Dependent Claim
18 words
The expert system (102) of claim 1, wherein said communication medium (202) comprises means for prioritizing said questions.
Claim 5
Dependent Claim
32 words
The expert system (102) of claim 1, further comprising: (5) a knowledge base (238) having: (a) forward rules for hypothesizing network problems; and (b) backward rules for verifying said hypothesized network problems.
Claim 6
Dependent Claim
37 words
An expert system (102) for diagnosing data communication networks (142), the expert system (102) comprising a knowledge base (236) having: (1) forward rules for hypothesizing network problems; and (2) backward rules for verifying said hypothesized network problems.
Claim 7
Dependent Claim
40 words
The expert system (102) of claim 5 or 6, said forward rules comprising: (a) one or more conditions; and (b) a reference to one of said backward rules; wherein said referenced backward rule is processed when said conditions are satisfied.
Claim 8
Dependent Claim
32 words
The expert system (102) of claim 5 or 6, said backward rules comprising: (a) one or more conditions; and (b) an answer; wherein said answer is returned if said conditions are satisfied.
Claim 9
Dependent Claim
87 words
A computer-based method for diagnosing data communication networks (142), said method comprising the steps of: (a) receiving (408) events; (b) determining (422) whether said events are event/questions containing questions or event/answers containing answers; (c) processing (424) said questions if said events are said event/questions; (d) processing (440) pending questions with said answers if said events are said event/answers; (e) receiving (1518) operator instructions during said processing; (f) adjusting (1522) said processing according to said operator instructions; and (g) displaying (1514) progress reports of said processing to operators.
Claim 10
Dependent Claim
86 words
The method of claim 9, wherein step (c) comprises the steps of: (1) selecting (924) a highest priority question from said questions; (2) sending (936) a poll request to modules (214); (3) receiving (936) poll responses from said modules; (4) selecting (942) according to said poll responses a most capable module from said modules to process said highest priority question; (5) causing (946) said most capable module to process said highest priority question; and (6) processing (950) said highest priority question by said most capable module.
