标准范围

本建议|国际标准将通过参考其他规范来应用。完成了参考ITU-T Rec.X.851 | ISO/IEC 9804中定义的CCR服务,在此类规范范围内。提及CCR服务调用本建议|国际标准的程序来产生外部影响。本建议|国际标准在第9条中规定了ACSE的使用、演示和会议承载CCR语义的服务。只要不使用这些服务,就可以使用这种“引用”映射与使用相同关联的其他ASE或ASO造成的用户冲突。附录B定义了不同的可能会指定使用支持服务,以用于参考映射不合适的情况。本建议|国际标准规定了系统的静态和动态一致性要求执行这些程序。它不包含可用于证明符合性的测试。本版建议|国际标准规定了CCR协议版本2,该版本使用会话数据分离功能单元,用于保护不属于CCR原子操作的数据。1990年版ISO/IEC 9805规定了CCR协议版本1。本建议的1993/1994版|国际标准规定了静态承诺功能单元的CCR协议版本1和CCR协议版本2只有本国际标准规定了支持以下功能单元的协议元素:a) 静态承诺;b) 动态承诺;c) 只读;d) 一阶段承诺;e) 取消;和f) 重叠恢复。

This Recommendation | International Standard is to be applied by reference from other specifications. This is donewithin such specifications by reference to the CCR services defined in ITU-T Rec. X.851 | ISO/IEC 9804. A reference toa CCR service invokes the procedures of this Recommendation | International Standard to cause external effects.This Recommendation | International Standard specifies, in clause 9, a use of the ACSE, Presentation and Sessionservices to carry the CCR semantics. This "reference" mapping can be used whenever the use of these services does notconflict with the user made by other ASEs or ASOs that are using the same association. Annex B defines how a differentuse of supporting services may be specified, for use where the reference mapping is inappropriate.This Recommendation | International Standard specifies the static and dynamic conformance requirements for systemsimplementing these procedures. It does not contain tests which can be used to demonstrate conformance.This edition of this Recommendation | International Standard specifies CCR protocol Version 2, which makes use of theSession Data Separation functional unit to protect data not belonging to the CCR atomic action. The 1990 edition ofISO/IEC 9805 specified CCR protocol Version 1. The 1993/1994 edition of this Recommendation | InternationalStandard specified both CCR protocol Version 1 and CCR protocol Version 2, for the static commitment functional unitonly.This International Standard specifies the protocol elements that support the following functional units:a) static commitment;b) dynamic commitment;c) read only;d) one-phase commitment;e) cancel; andf) overlapped recovery.
