摘要
策略精化过程的主要难点在于网络的不同层次之间缺少统一的知识表示,且在不同层次的知识之间,缺少必要的映射和推理机制。为此,研究一种通过本体知识推理实现策略自动精化的方法。将本体工程引入策略网络系统,利用本体对网络知识进行定义,利用语义Web规则描述语言对底层策略行为进行语义描述,建立不同层次间的自动化推理机制。以QoS区分服务应用场景为例,实现了策略的自动精化过程。
The main difficulties of the policy refinement process are lacks of uniform description and the automatic mechanism for mapping and reasoning of knowledge On different network levels. A method to realize the automatic policy refinement using the ontology-reasoning was proposed. The ontology engineering was introduced into the policy-based network system. The uniform description of knowledge was given using the ontology Web language and the semantic description of low-level operations was given using the semantic Web rule language, through which the automatic reasoning mechanism between different levels and the automatic process of policy refinement in the field of the QoS DiffServ service were implemented.
