14、ational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fie

15、lds 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 the work. In the field of information technology, ISO and IEC have established a

16、joint technical committee, ISO/IECJTC1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least75% of the national bodies casting a vote. International Standard ISO/IEC

17、8650-2 was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology, Subcommittee SC21, Open systems interconnection, data management and open distributed processing, in collaboration with ITU-T. The identical text is published as ITU-T Recommendation X.247. This second edition can

18、cels and replaces the first edition (ISO/IEC8650-2:1995), which has been technically revised. ISO/IEC 8650 consists of the following parts, under the general title Information technology Open Systems Interconnection Protocol specification for the Association Control Service Element: Part 1: Protocol

19、 specification; Part 2: Protocol Implementation Conformance Statement (PICS) proforma. Annex A forms an integral part of this part of ISO/IEC8650. Annex B is for information only.iv blankBSISO/IEC8650-2:1997 BSI 04-2000 1 Introduction This Recommendation|International Standard is one of a set of Rec

20、ommendations|International Standards produced to facilitate the interconnection of information processing systems. It is related to other Recommendations and International Standards in the set as defined by the Reference Model for Open Systems Interconnection (see ITU-T Rec. X.200|ISO/IEC7498-1). Th

21、e Reference Model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable size. The goal of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection standards, the interconnection of in

22、formation processing systems: from different manufacturers; under different managements; of different levels of complexity; and of different technologies. ITU-T Rec. X.227|ISO/IEC 8650-1 specifies the connection-oriented mode protocol for the application-service-element for application-association c

23、ontrol: the Association Control Service Element (ACSE). The ACSE connection-oriented mode provides services for establishing and releasing application-associations. The ACSE protocol also includes an optional functional unit for exchanging information to support authentication during association est

24、ablishment. The ACSE services apply to a wide range of application-process communication requirements. To evaluate the conformance of a particular implementation, it is necessary to have a description of the capabilities and options which have been implemented. Such a description is called a Protoco

25、l Implementation Conformance Statement (PICS). This Recommendation|International Standard includes the PICS proforma for the connection-oriented ACSE protocol as defined in ITU-T Rec. X.227|ISO/IEC8650-1. 1 Scope This Recommendation|International Standard provides the Protocol Implementation Conform

26、ance Statement (PICS) proforma for the connection-oriented ACSE protocol specified in ITU-T Rec. X.227| ISO/IEC8650-1. This PICS proforma is in compliance with the relevant requirements, and in accordance with the relevant guidance, given in ITU-T Rec. X.296|ISO/IEC9646-7. Detail of the use of this

27、proforma is provided in this Recommendation|International Standard. The supplier of an implementation which is claimed to conform to ITU-T Rec. X.227|ISO/IEC8650-1 is required to complete a copy of the PICS proforma provided in Annex A, and is required to provide the information necessary to identif

28、y both the supplier and the implementation. 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Recommendation|International Standard. At the time of publication, the editions indicat

29、ed were valid. All Recommendations and Standards are subject to revision, and the parties to agreements based on this Recommendation|International Standard are encouraged to investigate the possibility of applying the most recent edition of the Recommendations and Standards indicated below.

43、e published proforma that have been applied. Suppliers of the proforma should modify the proforma, or attach relevant additional pages in order to apply the corrigenda, and then record the application of the corrigenda in Table A.1. Table A.1 A.2 Instructions A.2.1 Purpose and structure of the profo

44、rma The purpose of this PICS proforma is to provide suppliers of implementations of ITU-T Rec. X.227| ISO/IEC8650-1 with a consistent means of stating which capabilities have been implemented. The proforma is in the form of a questionnaire and consists of a set of items. An item is provided for each

45、 capability for which an implementation choice is allowed. Items are also provided for major mandatory capabilities for which no implementation choice is allowed. Each item includes an item number, an item description, a status value specifying the support requirement, and room for a support answer

46、to be provided by the supplier. This subclause provides general information and instructions for completion of the proforma. Subclause A.3 is for identification of the implementation. Subclause A.4 contains the means of specifying, at a high level, the protocol and corrigenda that have been implemen

47、ted. Subclause A.5 contains the global statement of conformance. Subclause A.6 onwards contain tables in which the supplier specifies details of the implementation options chosen. A.2.2 Symbols, terms and abbreviations A.2.2.1 Introduction Notations have been introduced in order to reduce the size o

48、f tables in the PICS proforma. These have allowed the use of multi-column layout where the columns are headed “Status”, and “Support”. The definition of each are given below. Additionally, the following definitions apply: A.2.2.1.1 (PICS) item: A row in a PICS proforma table. A.2.2.1.2 (PICS) questi

49、on: The question to be answered in the intersection of a PICS item and either a support column (i.e. “Is this item supported in the context applying to this table and column”) or supported values column (i.e. “What values are supported for this item in the context applying to this table and column”) in a PICS proforma table. A.2.2.1.3 status (value): An allowed entry in the status column for an item in a PICS proforma table. A.2.2.1.4 (support) answer: An allowed entry in the support or supported
