摘　　要：本文描述了用于EtherNet/IP的一个协议,可以在网络基础架构和终端设备网络接口上提供多重容错功能。这种协议称为信标冗余协议或者BRP。基于BRP协议的网络可称为BRP网络。BRP网络基于ISO/IEC8802-3(以太网)和IEEE802.1标准以及冗余基础架构。在BRP网络中,网络切换由终端设备自己决定。BRP协议可以在有一万个终端设备或者更大的网络中使用。最遭的情况,典型的故障检测和切换时间为1ms或者更短。The paper describes a protocol for EtherNet/IP networks that can tolerate multiple failures in network infrastructure and network interfaces on end devices.This protocol is called Beacon Redundancy Protocol or BRP.A network based on the BRP protocol is called an BRP network.The BRP network is based on ISO/IEC 8802 3（Ethernet） and IEEE 802.1 standards and redundant infrastructure.In BRP network,the decision to switch between infrastructures is made individually in each end device.The BRP protocol allows realization of very large networks with 10,000 end devices or more and with worst case fault detection and switchover time of 1 ms or less for most types of faults.

关 键 词：高可用性网络 信标冗余网络 切换时间
