摘要

冗余以太网拓扑包括RSTP (Rapid Spanning Tree Protocol)、HSR (High-availability Seamless Redundancy)和PRP (Parallel Redundancy Protocol)。通常使用PTP (Precision Time Protocol)协议对此类网络中的节点进行同步。冗余拓扑可用于监视PTP功能，例如检测不对称、非功能设备，并在安装和操作期间提供帮助。

PTP monitoring in redundant network

Redundant Ethernet topologies such as Rapid Spanning Tree Protocol (RSTP), High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) are used in automation systems. Commonly Precision Time Protocol (PTP) is used to synchronize nodes in such networks. The redundant topology can be utilized to monitor PTP functionality - such as to detect asymmetries, non-functional devices and to help during installation and operation.
