Abstract
Abstract An expert system (102) for diagnosing data communication networks (142). The expert system (102) operates according to a landmark data abstraction paradigm and a hypothesis and verification process (2602). According to the hypothesis and verification process (2602), the expert system (102) diagnoses data communication networks (142) by hypothesizing network problems (2302) and then verifying the hypothesized network problems (2302).

Claim 1
Independent Claim
29 words
A computer-based method for diagnosing data communication networks (142), said method comprising the steps of: (a) hypothesizing (2506) network problems (2302); and (b) verifying (2510) said network problems (2302).
Claim 2
Dependent Claim
48 words
The method of claim 1, wherein step (a) comprises the steps of: (1) collecting (2614) network data (2304); (2) interpreting (2624) said network data (2304) to determine whether primary landmarks (2402) exist; and (3) interpreting (2628) said primary landmarks (2402) which exist to hypothesize said network problems (2302).
Claim 3
Dependent Claim
63 words
The method of claim 2, wherein step (b) comprises the steps of: (1) collecting (2644) second network data (2304); (2) interpreting (2648) said second network data (2304) to determine whether secondary landmarks (2402) exist; (3) confirming (2652) said network problems (2302) when said secondary landmarks (2402) exist; and (4) rejecting (2666) said network problems (2302) when said secondary landmarks (2402) do not exist.
Claim 4
Dependent Claim
14 words
The method of claim 1, wherein said method operates in an expert system (102).
Claim 5
Dependent Claim
40 words
The method of claim 4, wherein step (a) comprises the steps of: (1) selecting (2606) forward rules; (2) collecting (2614) network data (2304); and (3) interpreting (2624) said network data (2304) to determine whether said selected forward rules are satisfied.
Claim 6
Dependent Claim
75 words
The method of claim 5, wherein step (b) comprises the steps of: (1) initiating (2636) backward rules when said selected forward rules are satisfied; (2) collecting (2644) second network data (2304); (3) interpreting (2648) said second network data (2304) to determine whether said backward rules are satisfied; (4) confirming (2652) said network problems (2302) when said backward rules are satisfied; and (5) rejecting (2666) said network problems (2302) when said backward rules are not satisfied.
