摘要
对可扩展路由器的研究现状进行了综述,并在可扩展路由器体系结构和模型研究的基础上提出其分层模型,将可扩展路由器"自底向顶"地划分为互连结构和数据交换层,路由查找层、标准接口层、分布式操作系统层、分布式路由行为层和单映像管理层6层,并综述了每层的研究进展.最后进行了总结并分析了当前可扩展路由器发展的难点.
This paper presents a survey on the study of the scalable router and proposes a hierarchical model based on the study of the architecture and models of the scalable router. The model splits the scalable router into six layers from bottom to top, which are interconnection network and data switching layer, routing lookup layer, standard interface layer, distributed operating system layer, distributed routing behavior layer and single image management layer. The paper provides surveys on the research of each layer, and finally concludes and analyses the difficulties of current development of the scalable router.
