IP 分类算法是提高网络设备性能的关键，无冲突规则集则是正确进行IP 报文分类的
前提和保证。网络处理器Intel IXP1200 具有强大的可编程能力和并行分组处理能力。本文在IXP1200 处理器平台上设计实现了一种无冲突的多维IP 分类算法，用于保证当规则数量增加时，网络设备的数据分组转发仍能够保持正确和高速。
关键字：网络处理器，多维IP 分类，规则冲突，并行
Abstract：IP Classification algorithm is the key for improving the performance of network
equipments, while conflict-free filters is the premise and can assure the correctness of the IP
packet classification. With its programmable ability, the network processor Intel IXP1200 is
particularly powerful in parallel packet-processing. This paper describes the design and
implementation of a conflict-free multi-dimensional IP classification algorithm based on IXP 1200 network processor, which has the special ability to keep a fast and correct transmission of the data packets under the boosting number of the rules.
Key words：network processor，multi-dimensional IP classification, conflict-filter，parallel
