摘　　要：随着网络应用业务的不断增长,传统网络业务处理方案已不能满足新一代智能化网络设备设计要求。网络处理器具有强大协议处理能力和灵活可编程性特点,是下一代网络的核心技术之一。在分析研究了NP-2网络处理器的功能特点之后,介绍了一种基于网络处理器的高速转发模块设计方案,包括硬件设计、数据包转发流程,并给出了有关的转发性能测试数据。经测试验证,这种设计方案具有很高的报文处理和转发效率。With the development of network application, the traditional network application solution can＇t meet the design requirements of new-generation intelligentized network devices. The network processor has powerful packet processing ability and flexible programmable characteristic, so it has already become one of the key technologies used in next-generation network. After analyzing the characteristics of NP-2 network processor family, the paper presents the implementation of high-speed packet processing module based on NP, including hardware design, data flow description in packet processing and relational processing capability testing. Experiments prove that this design scheme can attain the high efficiency of packet processing.
