摘要

协调是大规模分布式系统的一个重要方面。开放平台通信统一体系结构(OPC UA)标准系列对服务器冗余规范的协调提出了重要挑战。本文明确了OPC UA服务器冗余的协调需求，提出了一种基于OPC UA与ZooKeeper集成的解决方案。给出了系统的体系结构、数据模型和组件的详细描述。本文还讨论了基于开源ZooKeeper和open62541库的实现。结果表明，该系统能够满足OPC UA冗余的协调需求。

Coordinating redundant OPC UA servers

Coordination is an important aspect of large scale distributed systems. The Open Platform Communications Unified Architecture (OPC UA) standard series presents an important challenge for coordination in its specifications for server redundancy. This paper discerns the coordination needs of OPC UA server redundancy and presents a solution based on the integration of OPC UA and ZooKeeper. A detailed description of the architecture, data model, and components of the resulting system is given. This is accompanied by a discussion of an implementation based on the open source ZooKeeper and open62541 libraries. The resulting system is shown to be capable of meeting the coordination needs of OPC UA redundancy.
