基于本体的网络管理知识模型

Network Management Knowledge Model Based on Ontology

基于本体理论研究了网管知识模型,提出了网管知识模型的框架,将其划分为基本模型和集成模型两个层次.基本模型包括信息模型、功能模型、网络模型等,面向网管需求集成基本模型得到集成模型.研究了基于本体代数的知识模型集成和基于本体推理、查询的知识模型处理.设计了基于网管知识模型的网管系统原型,原型系统实现了知识处理和信息处理的分离,可定制所支持的网管业务,并支持知识层综合网管.原型系统证明了网管知识模型的有效性.

Ontology is defined as a formal explicit specification of conceptualization, the network management knowledge model based on ontology is explored. The framework of knowledge model is presented, which is divided into primitive model and integrated model. Primitive model includes information models, function models and network models. Integrated model is the result of integration of primitive models based on requirement of network management. The integration of knowledge model is based on ontology algebra and the process of knowledge model is based on ontology inference and query. A prototype of NMS is designed, which is based on the network management knowledge model. The main characters of the prototype are separation of knowledge process and information process, customization of supported operations and knowledge level integrated network management. The validity of knowledge model is illustrated by the prototype.
