信息技术 开放分布式处理 接口引用和联编

[中文适用范围]： 范围 接口参考对于 ODP 系统和 ODP 系统组联合之间的互操作至关重要。 接口引用包含建立绑定所需的信息，包括绑定到支持多种不同通信协议的节点处的对象以及绑定到不同管理域中的对象。 接口引用进一步体现了工程机制所需的信息，以在存在分布透明度（例如迁移透明度）的情况下维持计算对象之间的绑定。 它们是 ODP 位置和搬迁透明度的基础。 此建议|国际标准包括： · 绑定接口框架和通用绑定协议（针对流接口和操作接口）； · 接口引用的通用信息结构的规范（对于流接口和操作接口）； · 使用标准化协议传输时接口引用的表示； · 识别与个人透明度有关的界面参考的管理和传输程序； · 识别与创建或转换接口引用的绑定和联合相关的节点管理接口； · 确定服务质量信息和调用 QoS 或相关测量程序的要求。 此建议|国际标准提供了支持 ODP 系统中对象的计算绑定所需功能的工程描述。 群组通信的安全性和支持是重要问题，但不在本建议书 | 的范围之内。 国际标准。 2 本建议书的应用领域国际标准支持 ODP 系统之间的互操作。 [外文原描述]： Interface references are crucial to interworking between ODP systems and federation of groups of ODP systems. An interface reference embodies the information needed to establish bindings, including binding to objects at nodes that support several different communication protocols and binding to objects in different management domains. An interface reference further embodies the information required for the engineering mechanism to maintain bindings between computational objects in the presence of distribution transparencies such as migration transparency. They are the foundation of ODP location and relocation transparency. This Recommendation | International Standard includes: · a framework for binding interfaces and a generic binding protocol (for both stream and operational interfaces); · a specification of the generic information structure of interface references (for both stream and operational interfaces); · representation(s) for interface references when transferred using standardized protocols; · identification of procedures for the management and transfer of interface references with respect to individual transparencies; · identification of node management interfaces related to binding and federation which create or transform interface references; · identification of requirements for quality of service information and for invocation of QoS or related measurement procedures. This Recommendation | International Standard provides an engineering description of the functionality needed to support the computational binding of objects in ODP systems. Security and support for group communication are important issues, but not within the scope of this Recommendation | International Standard. 1.2 Field of Application This Recommendation | International Standard enables interworking between ODP systems.
