3、712-1 :1995(E) The Canadian Standards Association, which operates under the name CSA International (CSA), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-p
4、rofit, nonstatutory, voluntary membership association engaged in standards development and certification activities. CSA standards reflect a national consensus of producers and users - including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. Th
5、e standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate
6、 their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from wh
7、ich its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certi
8、fication process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Si
9、nce 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification
10、 and related services to meet national and international needs.

11、ederation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, ben
12、efiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Counci
13、l of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to
14、the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of
15、Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards
16、 are subject to periodiC review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with the Standards Council of Canada 45 OConnor Street, Suite 1200 Ottawa, Ontario, K1 P 6N7

34、cialized 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 fields of technical activity. ISO and IEC technical
35、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 joint technical committee, ISOIIEC JTC 1. Draft I
36、nternational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISOIIEC 13712-1 was prepared by Joint Technical Comm
37、ittee ISOIlEC ITC 1, Information technology, Subcommittee SC 21, Open systems interconnection, data management and open distributed processing, in collaboration with ITV-T. The identical text is published as ITU-T Rec ommendation X.880. This part of ISOIlEC 13712 is a partial revISIon of ISOIIEC 907
38、2-1:1989 and ISOIlEC 9072-2: 1989. ISOIlEC 13712 consists of the following parts, under the general title Information technology - Remote Operations: - Part I: Concepts, model and notation Part 2: OSI realizations - Remote Operations Service Element (ROSE) service definition Part 3: OSI realizations
39、 - Remote Operations Service Element (ROSE) protocol specification Annex A forms an integral part of this part of ISOIlEC 13712. Annexes B to D are for information only. iv ISO/IEC ISOIIEC 13712-1:1995(E) Introduction Remote operations (ROS) is a paradigm for interactive communication between object
40、s. As such it can be used in the design and specification of distributed applications. The basic interaction involved is the invocation of an operation by one object (the invoker), its performance by another (the performer), possibly followed by a report of the outcome of the operation being returne
41、d to the invoker. The concepts of ROS are abstract, and may be realized in many ways. For example, objects whose interactions employ ROS concepts may be separated by a software interface or by an OSI network. This Recommendation I International Standard describes the concepts and model of ROS. It us
42、es ASN.l to specify information object classes corresponding to the fundamental concepts of ROS, such as operation and error. This in tum provides a notation so that designers can specify particular instances of those classes, e.g. particular operations and errors. This Recommendation I Internationa
43、l Standard provides a generic set of PDUs which can be used in realizing the ROS concepts between objects remote from one another. These PDUs are used in the OSI realization of ROS, which are specified in the companion Recommendations I International Standards to this one. This Recommendation I Inte
44、rnational Standard also provides a number of definitions of general utility to designers of ROS-based applications. Annex A forms an integral part of this Recommendation I International Standard. Annexes B, C and D do not form an integral part of this Recommendation I International Standard. v ISOIl
45、EC 13712-1 : 1995 (E) INTERNATIONAL STANDARD ITU-T RECOMMENDATION INFORMATION TECHNOLOGY -REMOTE OPERATIONS: CONCEPTS, MODEL AND NOTATION 1 Scope This Recommendation I International Standard specifies the Remote Operations Service (ROS) using the Abstract Syntax Notation (ASN.l) to define informatio
46、n object classes corresponding to the fundamental concepts of ROS. This, in turn, provides the notation that will allow application designers to specify particular instances of these classes. This Recommendation I International Standard also provides a collection of definitions for specifying the ge
47、neric protocol between objects that communicate using ROS concepts. These definitions are used in the companion Recommendations I International Standards to this one to provide the protocol data units, the service primitives and the application context definitions used in the OSI realization of ROS.
48、 A number of definitions of general utility to designers of ROS-based applications is also provided. No requirement is made for conformance to this Recommendation I International Standard. 2 Normative references The following ITU-T Recommendations and International Standards contain provisions which
