摘　　要：为了在工业控制网络中应用传统的以太网技术 ,必须改善网络结构的健壮性 ,保证信号传输的实时性要求。文章讨论了工业控制网络拓扑结构的冗余容错设计、交换式以太网中涉及QoS实时性要求的两种等待队列和调度算法问题。简单叙述了最新提出的Ethernet/IP的结构及其解决设备互操作的方法。In order to adopt conventional Ethernet technology in process control network it is necessary to improve the robustness of the network structure, thus to ensure the real time requirement in signal transmission. The redundant and tolerance design of the topologic structure of the process network, two waiting queues and dispatching algorithm related to Qos real time requirement in switched Ethernet are discussed in the paper. The latest Ethernet/IP structure and its solution on solving inter-operation of equipment is described briefly. Key words Ethernet Process control network Qos Redundant design Ethernet/IP
