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.
