15、on for Standardization) and IEC (the International Electrotechnical Commission) formthe specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in thedevelopment of International Standards through technical committees established by the respective

16、 organization to dealwith particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest.Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in thework.In the field of information techno

17、logy, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. DraftInternational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publicationas an International Standard requires approval by at least 75 % of the national bodies casting

18、 a vote.International Standard ISO/IEC 9805-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Informationtechnology, Subcommittee SC 33, Distributed application services, in collaboration with ITU-T. The identical text ispublished as ITU-T Recommendation X.852.This third edition cancels and

19、 replaces the second edition (ISO/IEC 9805-1:1994), which has been technically revised.ISO/IEC 9805 consists of the following parts, under the general title Information technology Open SystemsInterconnection Protocol for the Commitment, Concurrency and Recovery service element: Part 1: Protocol spec

20、ification Part 2: Protocol Implementation Conformance Statement (PICS) proformaAnnexes A and B form an integral part of this part of ISO/IEC 9805.v,QWURGXFWLRQThis Recommendation | International Standard is one of a set of Recommendations | International Standards produced tofacilitate the interconn

21、ection of information processing systems. It is related to other Recommendation | InternationalStandards in the set as defined by the Reference Model for Open Systems Interconnection (see ITU-T Rec. X.200 |ISO/IEC 7498-1). The Reference Model subdivides the area of standardization for interconnectio

22、n into a series of layersof specification, each of manageable size.The goal of Open Systems Interconnection is to allow, with a minimum of technical agreement outside theinterconnection standards, the interconnection of information processing systems: from different manufacturers; under different ma

23、nagements; of different levels of complexity; and of different technologies.This Recommendation | International Standard specifies the protocol for the application-service-element forCommitment, Concurrency, and Recovery (CCR). These services are intended to be applicable to a wide range ofapplicati

24、on-process communication requirements.This Recommendation | International Standard specifies CCR Protocol Version 2. The 1990 edition of ISO/IEC 9805specified CCR protocol Version 1. The 1993/1994 editions of this Recommendation | International Standard specifiedboth CCR protocol Version 1 and CCR p

25、rotocol Version 2, for the static commitment functional unit only.The CCR protocol specification consists of the following main components:a) the specification of the CCR APDUs using Abstract Syntax One (ASN.1, ITU-T Rec. X.680 |ISO/IEC 8824-1);b) the elements of procedure for issuing CCR service in

26、dication and confirm primitives to the CCRservice-user when CCR APDUs are received and for the sending of CCR APDUs when CCR servicerequest and indication primitives are received from the CCR service-user;c) the CCR protocol machine specified in terms of a state table; andd) the presentation service

27、s (see ITU-T Rec. X.216 | ISO/IEC 8822) used for sending and receiving CCRAPDUs.The CCR protocol shares the presentation-service with other application-service-elements.The requirement to provide support for CCR together with other application-service-elements is satisfied by reference tothis Recomm

28、endation | International Standard.Annex A contains the definitions of the structure of the CCR APDUs.Annex B describes how the CCR can be used in combination with other ASEs that use the presentation service in a waythat is not compatible with the use of the presentation service by CCR as specified
