Knowledge Based Inference Network Fault Warning System

With the construction of our country informatization development and deepeningof network applications, network scale is larger, the structure is more complex, carryingbusiness also more and more diverse, these factors have greatly increased the difficultyof management. Can say, a business success or not, are increasingly dependent oninformation platform for the normal operation and high availability. The traditional ITmanagement rely heavily on management experience to maintain the stable operation ofinformation platform, the lack of Dev, performance, fault monitoring and otherfunctions in one of the overall management tool. In this case, the unit is in urgent needof a full-featured, high degree of automation integrated management tools--online faultearly warning system.With the help of network fault warning system, user can unit of network Devconfiguration, fault and comprehensive performance monitoring, to understand itsoperation state; to the timely detection of network fault and performance anomaly; fast,accurate positioning; to regulate, efficient treatment problem.According to the actual situation of the unit and to the similar system in-depthunderstanding, based on network management and related technologies were introducedand discussed, including system development framework for JSF, XML, SNMP simplenetwork management technology, the spanning tree protocol and knowledgerepresentation and reasoning. And then put forward a system construction the functionrequirement and design principle, and each part of the system requirements wereanalyzed in detail. According to the function of the system detailed design of the systemframework, module realization method, has analyzed network topological realizationtechnology, and design and implementation of a fault diagnosis knowledge base, tocomplete the detailed design of the system.This thesis designs a network fault warning system, can meet the current unitnetwork management needs, has strong practicability and universality.
