40、0 8571 is one of a set of International Standards produced 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 Interconnection (IS0 7498). The Reference Model subdivides the area of standa

41、rdization 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 different manufacturers b

42、) under different managements c) of different levels of complexity d) of different ages. IS0 8571 defines a File Service and specifies a File Protocol available within the application layer of the Reference Model. The service defined is of the category Application Service Element (ASE). It is concer

43、ned with identifiable bodies of information which can be treated as files, which may be stored within open systems or passed between application processes. IS0 8571 defines a basic file service. It provides sufficient facilities to support file transfer, and establishes a framework for file access a

44、nd file management. IS0 8571 does not speclfy the interfaces to a file transfer or access facility within the local system. It is recognised that, with respect to Communication Quality of Service, (described in 14.1.2.16), work is still in progress to provide an integrated treatment of quality of se

45、rvice acrcss all of the layers of the OS1 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 International Standard at a later time which reflects

46、further quality of service developments and integration. IS0 8571 consists of the following four parts. Part 1 : General introduction Part 2: Virtual Filestore definition Part 3: File Service definition Part 4: File Protocol specification - Open Systems Access and This part of IS0 8571 contains the

47、following annexes which form part of the standard. Annex A - Diagnostic parameter values Annex B - Relation of attributes to primitives Annex C - File transfer with commitment control Annex D - Reference to RAM control information Annex E - State transition diagrams 1 Scope and field of application

48、This part of IS08571 defines in an abstract way the externally visible file transfer, access and management service within the OS1 Application Layer in terms of: a) the primitive actions and events of the service; b) the parameter data associated with each primitive action and event; c) the relation

49、ship between, and the valid sequences of, these actions and events. The service defined in IS0 8571 -3 is that which is provided by the OS1 file transfer, access and management protocol IS0 8571-4 in conjunction with the Association Control Service Elements IS08649 and with the Presentation service IS0 8822. IS0 8571-3 does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. There is, therefore, no conformance to this part of IS0 8571. 2 References IS0 7498, Information Processing Systems
