摘    要:把决策树分类器引入包过滤技术当中,改变了传统的顺序检索包过滤的方法。以增加预处理时间为代价,提高了数据包的过滤速度。该文对决策树分类器的建树算法、搜索算法以及可递增性等关键技术进行了研究,并通过仿真实例和性能分析表明了该方法的有效性。

关 键 词:包过滤  规则  决策树  可递增性

Abstract:Introducing the decision tree classifiers into packet filtering tec hnology, it changes the conventional method searching the packet orderly. The ne w technique improves the filtering speed at the cost of preprocess time. Some ke y technologies such as the building and searching algorithms and the ability of increasable by degrees are researched. The instances and performance analysis pr ove the validity of this method.
Keywords:Packet filter  Rule  Decision tree  Increasable by degrees
