National bodies that are members of IS0

13、 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations

14、, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to nati

15、onal bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 10026-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 2 1, Open Systems Interco

19、ernational Standards produced to facilitate the interconnection of computer systems. It is related to other CCITI Recommendations I International Standards in the set as defined by the Reference Model for Open Systems Interconnection (ITU-T Rec. X.200 1 ISO/IEC 7498-l). The Reference Model subdivide

20、s the area of standardization for interconnection into a series of layers of specification, each of manageable size. The aim of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection standards, the interconnection of computer systems: a) from diff

21、erent manufacturers; b) under different management; c) of different levels of complexity; and, d) of different technologies. The Recommendations I International Standard for OS1 TP define a TP Model, a TP Service and specify a TP communications Protocol available within the Application Layer of the

22、OS1 Reference Model. The TP Service is of the category defined in the Application Layer Structure standard. It is concerned with identifiable information which can be related as transactions, which may involve two or more open systems. The Recommendations I International Standard for OS1 TP defines

23、a basic TP Service. It provides sufficient facilities to support transaction processing, and establishes a framework for coordination across multiple TP resources in separate Open Systems. The Recommendations I International Standard for OS1 TP does not specify the interface to local resources or ac

24、cess facilities that are provided within the local system. However detailed consideration of access to the local resources and their management may lead to some enhancement in a future revision of the Recommendations I International Standard. To evaluate conformance of a particular implementation, i

25、t is necessary to have a statement of which capabilities and options have been implemented for a given OS1 protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). The PICS Proforma, Annex A, has been designed to be a self contained section of this Recommendation

26、I Part of ISO/IEC 10026 for use in testing and procurement. V ISO/IEC 10026-4 : 1995 (E) INTERNATIONAL STANDARD ITU-T RECOMMENDATION INFORMATION TECHNOLOGY - OPEN SYSTEMS INTERCONNECTION - DISTRIBUTED TRANSACTION PROCESSING: PROTOCOL IMPLEMENTATION CONFORMANCE STATEMENT (PICS) PROFORMA 1 Scope This

27、Recommendation I International Standard provides the PICS proforma for the Distributed Transaction Processing protocol as specified in ITU-T Rec. X.862 I ISO/IEC 10026-3 in compliance with the relevant requirements, and in accordance with the relevant guidance, given in CCITT Rec. X.291 I ISO/IEC 96

28、46-2. Details of the use of this profonna is provided in this Recommendation I Part of ISO/IEC 10026. Implementors of implementations claiming conformance to ITU-T Rec. X.862 I ISO/IEC 10026-3 shall complete the proforma as part of the conformance requirements. The level of detail required in the pr

29、oforma exceeds that of the protocol specification by requiring details to uniquely identify the implementation and the supplier. NOTE - PICS are related to base standards and only base standards. PICS Proforma structure might be expanded and refined for other documents (e.g. ISPs) using the base sta

30、ndards (e.g. ISPICS Proforma). 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Recommendation I International Standard. At the time of publication, the editions indicated were val

31、id. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation I International Standard are encouraged to investigate the possibility of applying the most recent editions of the Recommendations and Standards listed below. Members of IEC and IS0

32、maintain registers of currently valid International Standards. The Telecommunication Standardization Bureau of ITU maintains a list of currently valid ITU-T Recommendations.

49、1 TP protocol. 7 Notations defined for the proforma In order to reduce the size of the tables in the PICS proforma, notations have been introduced. These have allowed the use of multi-column layout where the columns are PICS No., Item, Reference (to relevant clause of ISO/IEC 10026-3), Status, Support, Cross Reference (to another clause of the proforma - if any), VALUES, and Comment. Some of these columns are sub-divided to indicate separately the status or support as Sender (“Sdr”) or Receiver (“Rev”). The definition of each of these follows. 7.1 PICS number column This column contains a se
