摘要
随着网络向全IP化方向发展,ATM路由交换设备也将从原有ATM交换架构向以太网交换架构过渡。基于以太网架构进行设备开发已经是一种趋势,分别介绍了以太网、ATM的信息格式及应用特点,通过将以太网的带宽优势与ATM QoS优势相结合,提出了基于以太网交换架构实现ATM路由交换功能的设计思路。给出了基于以太网交换架构实现ATM路由交换功能的具体实现方法,详细阐述了设计思路、总线拓扑、信息承载格式、信息传递流程等主要内容。对于路由交换设备开发具有借鉴意义。
With the all-IP development of the network,the ATM routing switching equipment architecture is changed from ATM switch architecture to Ethernet switch architecture.The equipment development based on the Ethernet architecture has been a trend.This paper introduces the information format and application characteristics of Ethernet and ATM.By combining the bandwidth advantage of Ethernet with the advantage of ATM QoS,a design idea of implementing ATM routing switching based on Ethernet swithing architecture is proposed.The implementation of ATM routing switching based on Ethernet switching architecture is given.This paper elaborates the design idea,bus topology,information format,information transfer process,etc..It is of reference to the development of routing switching equipment.
