运行服务总线跨安全区的服务部署方式探讨*

运行服务总线（OSB）是一体化电网智能系统（OS2）的基础模块之一，如何在OSB中对用户屏蔽安全区，以满足电力二次系统安全防护方案的要求，同时将必要的数据或者服务进行跨区共享是一个重要的课题。分析了电力安全区的相关规定对于服务总线建设的影响；针对不同安全区之间网络访问壁垒，提出相应的可行性方案，多角度探讨运行服务总线在不同安全区之间服务的互联、互通以及部署问题。

Research on OSB-based Service Deployment Modes Over Multi-Security Zones

The operation service bus (OSB) is one of the core components of operation smart system (OS2). It is a key issue that how to provide transparent services to the customers so as to provide data sharing among multi-security zones, and satisfy the demand of security defending strategies of power secondary systems as well. According to the related regulations of security zones, this paper analyzes their impacts on the construction of OSB, and proposes a feasible solution that overcome the barriers among various security zones and thus support interconnection and intercommunication of services as well as the service depolyment .
