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.
