摘要/Abstract

摘要： 针对以太网交换技术中可靠性不能满足实际应用需求的问题, 提出以太网自动保护交换EAPS（Ethernet Automatic Protection Switching）技术.论述了EAPS技术特点、采用EAPS技术的以太网的物理构成要素、逻辑处理原理和网络拓扑结构的特点, 分析了以太网环中链接断开的3种处理手段, 并给出使用以太网自动保护交换技术后的测试数据.

关键词: EAPS域, 主节点, 端口, 链接断开

Abstract: In this article is introduced the Ethernet Automatic Protection Switching (EAPS) technology based on RFC3619. We analyzed the composition of the EAPS network and its operating principle firstly; then,described how EAPS technology dealt with the link down event; at last, we used the result of the EAPS test to probe the advantages of EAPS technology.

Key words: EAPS Domain, master node, port, link down
