摘　　要：在网络处理器的平台上开发了用户管理控制系统,用于对用户上网内容和行为进行监控。网络处理器是可编程的高效网络数据处理芯片,网络控制器是用户管控系统中用于过滤数据的器件。通过实验,在硬件方面使用优化流水线这一高效的芯片处理数据的方法来提升数据处理效率,在软件方面通过使用不同的算法来优化性能,这些算法包括流过滤算法、潜在语义索引算法和IP碎片处理技术。实验结果表明,基于网络处理器的网络控制器在根据过滤和转发规则对数据过滤和转发时准确率高,速度快,非常好地达到了对用户上网内容和行为监控的效果。A user management system in network processor developed, it is used for monitor the user internet content and behavior. Network processor is programmable and high efficient network data processing chip, the internet controller in the user management system is used for data filtering and for- warding device. Through the experiment, in terms of hardware a efficient data processing method is used which is optimization of pipeline by the chip, it is to improve the efficiency of data processing, in terms of software by using different algorithms to optimize performance, these algorithms include flow filtering algorithm, latent semantic indexing algorithm and IP fragment processing technology. The experimental results show that, based on the network processor the internet controller to filter and forwards the data by the filtering and forwarding rules at high accuracy, fast speed, it is good for users internet content and behavior monitoring effect.
