摘为了在性能和灵活性上同时满足网络高速数据处理的要求。在现今的路由体系设计中采用了网络处理器。介绍了网络处理器的特点、结构及关键技术,并以Intel IXP2400为例对基于网络处理器的路由体系典型结构进行了设计分析,在性能和灵活性上取得了很好的平衡,具有很好的发展前景。
NP(network processor) is applied in the current design of routing architecture to meet the demand of high-speed data process with high performance and strong flexibility. In this paper, the features, architecture and key technologies of NP are introduced. And the typical structure of routing architecture based on NP is designed and analyzed with the example of Intel IXP2400. It gets a blance between performance and flexibility,which has great prospects.
