ISO/IEC 19500-2:20 12规定了一种全面、灵活的方法来支持分布在多个异构CORBA兼容对象请求代理（ORB）之间并由其管理的对象网络。ORB间操作的方法是通用的，因为元素可以以多种方式组合以满足非常广泛的需求。 ISO/IEC 19500-2:20 12规定 ORB互操作性体系结构 球间桥支架 用于对象请求代理（ORB）互操作性的通用ORB间协议（GIOP）。GIOP可以映射到满足本国际标准定义的一组最小假设的任何面向连接的传输协议上 Internet ORB间协议（IIOP），直接在使用Internet协议和传输控制协议（TCP/IP连接）的连接上运行的GIOP的特定映射 CORBA安全属性服务(SAS)协议及其在CSIv2体系结构中的使用，以满足CORBA安全性对可互操作身份验证、委托和特权的要求 ISO/IEC 19500-2:20 12提供了ITU-T Rec的广泛实施和使用的规范。X.931 ISO/IEC 14752。它支持ODP系统中的互操作性和位置透明性。

ISO/IEC 19500-2:2012 specifies a comprehensive, flexible approach to supporting networks of objects that are distributed across and managed by multiple, heterogeneous CORBA-compliant Object Request Brokers (ORBs). The approach to inter-ORB operation is universal, because elements can be combined in many ways to satisfy a very broad range of needs. ISO/IEC 19500-2:2012 specifies

• ORB interoperability architecture
• Inter-ORB bridge support
• General Inter-ORB Protocol (GIOP) for object request broker (ORB) interoperability. GIOP can be mapped onto any connection-oriented transport protocol that meets a minimal set of assumptions defined by this International Standard
• Internet Inter-ORB Protocol (IIOP), a specific mapping of the GIOP which runs directly over connections that use the Internet Protocol and the Transmission Control Protocol (TCP/IP connections)
• CORBA Security Attribute Service (SAS) protocol and its use within the CSIv2 architecture to address the requirements of CORBA security for interoperable authentication, delegation, and privileges

ISO/IEC 19500-2:2012 provides a widely implemented and used particularization of ITU-T Rec. X.931 | ISO/IEC 14752. It supports interoperability and location transparency in ODP systems.
