摘　　要：随着网络技术的高速增长,包分类技术的关键性日益凸显。由于网络处理器具有灵活编程和高速处理的能力,已成为当今网络中数据处理的有效解决方案。该研究用微码实现了二次Hash算法,解决了IXP2400网络处理器数据包信息存储空间有限和访问及时性相互制约的问题,在Intel的仿真环境Workbench下验证完成多个连接的ATM信元的同时分类重组实验,为高速数据流的线速处理提供了借鉴。With the high speed growth of the network technology, packet classification is more and more important. The network processor has the ability of flexible programmed and high speed processing, so it becomes the valid solution on net- work data handle in nowadays. This research carries out quadratic Hash arithmetic by mirco - code, which solves the balance between the limited date memory and timely accessing. With the Intel emulator workbench, this research classifies the ATM ceils which belong to multi - links. It proves to be a valuable solution to high speed data processing.
