ISO/IEC 17963:2013描述了一种基于SOAP的Web服务协议,用于特定于管理的域。这些域包括诸如PC、服务器、设备、Web服务和其他应用程序可管理的实体的管理。服务可以只公开一个WS-Management接口,也可以将WS-Management服务接口与许多其他Web服务规范中的一些规范组合在一起。这些服务的一个重要应用是在系统管理领域。为了促进管理应用程序和托管资源之间的互操作性,ISO/IEC PAS 17963:2012确定了一组核心Web服务规范和使用要求,这些规范和要求公开了一组对所有系统管理至关重要的通用操作。这包括执行以下操作的能力:a)获取、放置(更新)、创建和删除单个资源实例,例如设置和动态值;b)枚举容器和集合的内容,如大型表和日志;c)订阅由托管资源发出的事件;d)使用强类型的输入和输出参数执行特定的管理方法。在这些范围的每个领域中,ISO/IEC 17963:2013定义了符合性Web服务实现的最低实现要求。实现可以自由地扩展到这组操作之外,并且如果功能不适合于目标设备或系统,则选择不支持前述功能领域中的一个或多个。ISO/IEC 17963:2013旨在满足以下要求:a)约束Web服务协议和格式,使得Web服务可以在硬件和软件管理服务中以较小的占用空间实现;b)在不限制更丰富的实现的情况下定义合规性的最低要求;c)确保与WS-Management 1.0版的向后兼容性和互操作性;d)确保与其他Web服务规范的可组合性。
ISO/IEC 17963:2013describes a Web services protocol based on SOAP for use in management‑specific domains. These domains include the management of entities such as PCs, servers, devices, Web services and other applications manageable entities. Services can expose only a WS-Management interface or compose the WS-Management service interface with some of the many other Web service specifications.
A crucial application for these services is in the area of systems management. To promote interoperability between management applications and managed resources, ISO/IEC PAS 17963:2012 identifies a core set of Web service specifications and usage requirements that expose a common set of operations central to all systems management. This includes the ability to do the following:
a) get, put (update), create, and delete individual resource instances, such as settings and dynamic values;
b) enumerate the contents of containers and collections, such as large tables and logs;
c) subscribe to events emitted by managed resources;
d) execute specific management methods with strongly typed input and output parameters.
In each of these areas of scope, ISO/IEC 17963:2013 defines minimal implementation requirements for conformant Web service implementations. An implementation is free to extend beyond this set of operations, and to choose not to support one or more of the preceding areas of functionality if that functionality is not appropriate to the target device or system.
ISO/IEC 17963:2013 intends to meet the following requirements:
a) constrain Web services protocols and formats so that Web services can be implemented with a small footprint in both hardware and software management services;
b) define minimum requirements for compliance without constraining richer implementations;
c) ensure backward compatibility and interoperability with WS-Management version 1.0;
d) ensure composability with other Web services specifications.
