摘　　要：内容过滤是网络安全领域中的一个重要组成部分。它对应用层内容协议中传输的信息进行分析,并根据过滤条件控制信息的转发。网络处理器是新一代用来执行数据处理和转发的高速可编程处理器。它以其在网络数据处理方面的明显优势,成为高速网络设备中支持业务管理、安全与网络监控等网络功能必不可少的元件。根据网络处理器的优势,给出了一个基于Intel IXP2400网络处理器内容过滤系统的实现。Content filtering is an indispensable important part in the network security field. It analyses the information transported in application layer content protocol and controls the forwarding of the information based on the filtering rules. Network Processor is a new generation programmable processor of high speed for carrying out data processing and transmitting. With its obvious advantages in network data processing, the network processor becomes the essential component in high-speed network equipment which supports network functions, such as operation management ,security and network monitoring, etc. Based on the advantage of network processor, this paper presented an implementation of an Intel ⅨP2400 network processorbased content filtering system.
