摘　　要：为了改进目前IP路由器的可扩展性和灵活性等特点,研究基于开放可编程的新一代路由器架构。介绍了控制和转发相分离的ForCES协议框架和In te l IXA结构,提出了一种基于网络处理器IXP 2400并支持ForCES协议的开放可编程的路由器框架。详细地分析了转发件中X sca le层的设计和实现。在此基础上设计了相应的测试平台,实验结果表明了这种路由器框架的可行性。A frame of open programable-based new router is researched in order to improve expansibility and flexibility of IP router. The forwarding and control element separation protocol and Intel Internet exchange architecture is introduced,then an open programmable structure of router based on network processors IXP2400 and ForCES protocol is proposed. The design and implementation of FE Xscale layer is analyzed in detail. Hardware test plane is constructed and corresponding result is given after testing. The result indicates that this kind of router architecture is practical.
