29、rldwide 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 fields of technical activity. ISO and IEC technical committees collaborate

30、 in fields of mutual interest. Other international organizations, governmental or 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 joint technical committee, ISO/IECJTC1. In addition to developing Intern

31、ational Standards, ISO/IECJTC1 has created a Special Group on Functional Standardization for the elaboration of International Standardized Profiles. An International Standardized Profile is an internationally agreed, harmonized document which identifies a standard or group of standards, together wit

32、h options and parameters, necessary to accomplish a function or set of functions. Draft International Standardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires approval by at least 75% of the national bodies casting a vote. Inte

33、rnational Standardized Profile ISO/IECISP10607-4 was prepared with the collaboration of Asia-Oceania Workshop (AOW); European Workshop for Open Systems (EWOS); Open Systems Environment Implementors Workshop (OIW). ISO/IEC ISP 10607 consists of the following parts, under the general title Information

34、 technology International Standardized Profiles AFTnn File Transfer, Access and Management: Part 1: Specification of ACSE, Presentation and Session protocols for the use by FTAM; Part 2: Definition of document types, constraint sets and syntaxes; Part 3: AFT11 Simple File Transfer Service (unstructu

This second edition cancels and replaces the first edition (ISO/IECISP 10607-4:1991), which has been technically revised. It also incorporates amend

36、ment 1:1994. Annexes A and B form an integral part of this part of ISO/IEC ISP 10607. Annexes C and D are for information only.iv blankENISP10607-4:1996 BSI 02-1999 1 Introduction This part of ISO/IEC ISP 10607 is defined within the context of Functional Standardization, in accordance with the princ

37、iples specified by ISO/IEC TR 10000, “Framework and Taxonomy of International Standardized Profiles”. The context of Functional Standardization is one part of the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms.

38、A profile defines a combination of base standards that collectively perform a specific well-defined IT function. Profiles standardize the use of options and other variations in the base standards, and provide a basis for the development of uniform, internationally recognized system tests. One of the

39、 most important roles for an ISP is to serve as the basis for the development (by organizations other than ISO and IEC) of internationally recognized tests and test centres. ISPs are produced not simply to legitimize a particular choice of base standards and options, but to promote real system inter

40、operability. The development and widespread acceptance of tests based on this and other ISPs is crucial to the successful realization of this goal. The text for this part of ISO/IECISP10607 was developed in close co-operation among the FTAM Expert Groups of the three International OSI/OSE Workshops:

41、 OSE Implementors Workshop (OIW), the European Workshop for Open Systems (EWOS) and the Asia-Oceania Workshop (AOW). This part of ISO/IECISP10607 is harmonized among these three Workshops and it was finally ratified by the Workshops plenary assemblies. 1 Scope 1.1 General This part of ISO/IECISP1060

42、7 (AFT12) covers transfer of files between the filestores of two end systems, using the OSI connection-mode transport service to provide the interconnection. One end system acts in the initiator role and requests access to the file, the other end system acts in the responder role and provides access

43、 to the file in the virtual filestore. These role combinations and the interoperability are shown inTable 1. Table 1 Interoperable configurations Transfer of files is supported for files with an unstructured, flat or random access constraint set and containing binary or character data. This part of

44、ISO/IECISP10607 specifies implementations that support file transfer, i.e. the ability to a) either read a complete file, or b) write (replace and/or extend and/or insert, depending on constraint set and document type) to a file, or c) both; and optionally to a) create and delete a file, and b) read

45、 the attributes of a file. This part of ISO/IECISP10607 specifies how the OSI FTAM application standard shall be used to provide the functions defined above. It does not specify total system capability. In particular, a system may operate this profile and at the same time engage in other communicati

46、ons. The requirements placed on an implementation in this part of ISO/IECISP10607 are solely those necessary for operation of the protocol specified. This part of ISO/IECISP10607 describes the actions and attributes of the virtual filestore, and the service provided by the file service provider to f

47、ile service users, together with the necessary communications between the initiator and the responder. 1.2 Position within the taxonomy This part of ISO/IECISP10607 is identified in ISO/IECTR10000-2 as “AFT12-Positional File Transfer Service (flat)”. It may be combined with any T-Profiles (see ISO/I

48、ECTR10000) specifying the OSI connection-mode transport service. 1.3 Scenario The model used is one of two end systems establishing an association and transferring files into and out of the responders virtual filestore as shown inFigure 1.

The mapping between the virtual filestore and the real filestore together with the local data management system is not defined in this part of ISO/IECISP10607. This part of ISO/IECISP10607 defines the selection of specific virtual filestore options, file service options and file protocol options. The requ
