基于网络处理器的多维IP分类算法

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IntelIXP1200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。

Multi-Dimensional IP Classification Based On Network Processor

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.
