15、 ISO (the International Organization for Standardization) and IEC (the International 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 comm

16、ittees established by the respective organization to deal with 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 the

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

18、east75% of the national bodies casting a vote. International Standard ISO/IEC8571-5 was prepared by Joint Technical Committee ISO/IECJTC1, Information technology. ISO 8571 consists of the following parts, under the general title Information processing systems Open Systems Interconnection File Transf

19、er, Access and Management: Part 1: General introduction; Part 2: Virtual Filestore Definition; Part 3: File Service Definition; Part 4: File Protocol Specification; Part 5: Protocol Implementation Conformance Statement Proforma. Annex A forms an integral part of this part of ISO8571.Annex B is for i

20、nformation only.iv blankISO/IEC8571-5:1990(E) BSI 02-2000 1 Introduction ISO 8571 is one of a set of International Standards introduced to facilitate the interconnection of computer systems. It is related to other International Standards in the set as defined by the Reference Model for Open Systems

21、Interconnection (ISO7498). The Reference Model subdivides 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 standard

22、s, the interconnection of computer systems a) from different manufacturers, b) under different managements, c) of different levels of complexity, d) of different ages. ISO 8571 defines a File Service and specifies a File Protocol available within the application layer of the Reference Model. The ser

23、vice defined is of the category Application Service Element (ASE). It is concerned with identifiable bodies of information which can be treated as files, which may be stored within open systems or passed between application processes. ISO 8571 defines a basic file service. It provides sufficient fac

24、ilities to support file transfer, and establishes a frame-work for file access and file management. ISO8571 does not specify the interfaces to a file transfer or access facility within the local system. It is recognised that, with respect to Communication Quality of Service, work is still in progres

25、s to provide an integrated treatment of quality of service across all of the layers of the OSI Reference Model and to ensure that the individual treatments in each layer service satisfy overall quality of service objectives in a consistent manner. As a consequence, an addendum may be added to this I

26、nternational Standard at a later time which reflects further quality of service developments and integration. To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given OSI protocol. Such a statement

27、 is called a Protocol Implementation Conformance Statement (PICS). 1 Scope This part of ISO8571 defines a Protocol Implementation Conformance Statement (PICS) proforma for the detailed expression of the conformance requirements of ISO8571. This PICS proforma is in compliance with the relevant requir

28、ements and in accordance with the relevant guidance for a PICS proforma given inISO9646-2. Detail of the use of this proforma is provided in this part of ISO8571. Implementations claiming conformance to ISO8571 shall complete the proforma as part of the conformance requirements. The level of detail

29、required in the proforma exceeds that of the protocol specification by requiring details to uniquely identify the implementation and the supplier. NOTEPICS are related to base standards and only base standards. PICS structure might be expanded and refined for other documents using the base standards

The PICS pr

38、oforma annex has been designed to be a self-contained section of this part of ISO8571, for use in testing and procurement. 6 Conformance A conforming PICS shall be technically equivalent to the ISO published PICS proforma and shall preserve the numbering and ordering of the items in the ISO PICS pro

39、forma. A PICS which conforms to this part of ISO8571 shall a) describe an implementation which conforms to ISO8571-4 b) be a conforming PICS proforma, which has been completed in accordance with the instructions for completion given inclausesA.8 andA.10 ofAnnex A c) include the information necessary

40、 to uniquely identify both the supplier and the implementation 7 Description of the proforma The proforma defined inAnnex A is divided into the following sections: a) Implementation detail (see7.1) b) General ISO 8571 detail (see7.2) c) Syntax detail (see7.3) d) Virtual Filestore detail (see7.4) e)

41、File Protocol detail (see7.5) f) Document Type detail (see7.6) Throughout each section, whenever a line contains a requirement for an implementation response, that line is numbered at the left hand side. For the significance of this numbering seeclause9. 7.1 Implementation detail The implementation

42、detail provides a number of items of information which allow a unique identification of an implementation and the supplier. These are implementor and supplier specific. 7.2 General ISO 8571 detail The general detail covers general detail of ISO8571. This includes information on which protocol versio

43、n numbers, addenda and defect reports have been included in the implementation. Also specified in this section is a statement of which roles have been implemented from the ranges of initiator/responder and sender/receiver. 7.3 Syntax detail The abstract syntaxes identified are those defined for the

44、basic operation of the protocol and the implementation of the hierarchical file model. Support for abstract syntaxes defined as part of a document type is defined in section6 (document type detail). Conformance to the syntactic elements of the protocol which cannot be exercised because of overriding

45、 application semantic constraints is outside the scope of the individual PICS. 7.4 Virtual Filestore detail The virtual filestore detail provides information on which virtual filestore model has been implemented and if the hierarchical model defined in ISO8571-2 has been implemented. The section con

46、tinues to identify the detail of the model. Definition of other filestore models is for future study and the detail in this section may or may not be relevant. 1) To be published.ISO/IEC8571-5:1990(E) BSI 02-2000 3 As the virtual filestore is always in the role of responder a certain asymmetry devel

47、ops within the PICS with some features for the responder implementation being specified in this Virtual Filestore section while the initiator implementation detail is specified in the protocol section. 7.5 File Protocol detail Comprising the major portion of the PICS, the file protocol detail sectio

48、n establishes which fields of which PDUs are implemented. It requires a statement of the value range supported and a reference to further detail for many of the fields. 7.6 Document Type detail Document type detail is included in the PICS to reflect the detail in ISO8571-2. It is not necessary, for

49、conformance purposes, to implement any of the document types defined in ISO8571-2. The style of the proforma in this section may be used to specify support of further document types. 8 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 headed “D”, “I” or “R” The definition of each of these follows. 8.1 D column “D” Defined in ISO8571. This column i
