Abstract: This paper introduces the basic configuration mode of network processor, including parallel configuration and serial configuration. Based on parallel configuration, the action of router in IPv4 is analyzed. After abstracting the common characteristic of diverse NP of processing packet, the relationship between the number of thread and number of micro-engine is analyzed. The efficiency of the NP is discussed with focus on how to improve the efficiency under limited resources.

Key words: network processor, IPv4, micro-engine, thread, co-processor

摘要： 介绍了网络处理器基本配置方式：并行配置和串行配置。在并行配置的基础上，分析了IPv4对网络处理器报文处理的要求，提取了不同网络处理器报文处理的共同特征。讨论了在网络处理器饱和工作条件下内部线程个数和引擎个数之间的关系以及网络处理器的效率问题，为在相同的资源条件下，如何提高其性能作出了前期研究。
