1、National Standard of CanadaCAN/CSA-ISO/IEC 9314-20:04(ISO/IEC 9314-20:2001)International Standard ISO/IEC 9314-20:2001 (first edition, 2001-03) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 9314-20:04, which has been approved as a NationalStandard of Canada by the Standa

3、 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-profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.
4、CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal government
5、s in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supportin
6、g the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development
7、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 certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In add
8、ition 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. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent se
9、rvice 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 and related services to meet national and international needs.For further information on CSA services, write toCanadia
10、n Standards Association5060 Spectrum Way, Suite 100Mississauga, Ontario, L4W 5N6CanadaThe Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary
11、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, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and
12、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 Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose colle
13、ctive 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 the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the n
14、ational 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 Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of
15、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 are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization prepa
16、ring the standard.The responsibility for approving National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaAlthough the intended primary application of this Standard is stated in its Scope, it is importantto note that it remains

40、k and is designed for efficient operation witha peak data rate of 100 Mbit/s. It uses a Token Ring Architecture with optical fibre as thetransmission medium. FDDI provides for hundreds of stations operating over an extent of tensof kilometres.The FDDI Physical Media Dependent (PMD) standard, ISO/IEC
41、 9314-3, specifies the lowersublayer of the Physical Layer for the FDDI, including the optical interface for multimode fibreFDDI stations. This part of ISO/IEC 9314 is an abstract test suite (ATS) conformance test forFDDI PMD. ISO/IEC 9314-3 specifies the optical interface of FDDI stations. ISO/IEC
42、9314-3 isnot a protocol standard and this part of ISO/IEC 9314 requires the measurement of physicalquantities such as optical power, wavelength and signal jitter. The intent of this part ofISO/IEC 9314 is to specify the tests as broadly as possible to allow measurement by variousdetailed test implem
43、entations. The ATS in this part of ISO/IEC 9314 differs from themethodology of higher level protocol conformance tests written using the Tree and TabularCombined Notation (TTCN) because TTCN does not provide for Physical Layer testing, wherethere is no concept of a protocol data unit and where physi
44、cal quantities must be measured.Four other ISO/IEC standards provide a complete conformance test of an FDDI station:a) An ATS for the FDDI Physical Layer Protocol (PHY) that provides a conformance test forFDDI PHY, ISO 9314-1. ISO 9314-1 specifies the upper sublayer of the Physical Layer forthe FDDI
45、, including the data encode/decode, framing and clocking, as well as the elasticitybuffer, smoothing and repeat filter functions. FDDI PHY, however, does contain severalstate machines and implements a protocol at the level of FDDI code symbols. The onlyphysical quantity that is measured in this conf
46、ormance test is frequency. The PHY ATScannot use the TTCN notation and a notation is developed in the PHY ATS for specifyingtest patterns and expected results in terms of FDDI code symbol strings.b) An ATS for FDDI Media Access Control (MAC), ISO 9314-2, that provides a conformancetest for FDDI MAC.
47、 ISO 9314-2 specifies the lower sublayer of the Data Link Layer forFDDI. It specifies access to the medium, including addressing, data checking and dataframing. ISO 9314-2 also specifies the receiver and transmitter state machines. SinceMAC is primarily with complete PDUs, the TTCN language is used
48、to specify MAC protocoltests. Provisions of ISO/IEC 9314-2, however, require high resolution timing that may bedifficult to achieve in commercial protocol testers.c) An ATS for FDDI Station Management (SMT), ISO/IEC 9314-6, that provides aconformance test for FDDI SMT. ISO/IEC 9314-6 specifies the l
49、ocal portion of the systemmanagement application process for FDDI, including the control required for properoperation of an FDDI station in an FDDI ring. SMT provides services such as connectionmanagement, station insertion and removal, station initialization, configuration manage-ment and fault recovery, communications protocol for external authority, schedulingpolicies and the collection of statistics. SMT interacts with PMD, PHY and MAC.Therefore, an ATS for portions of SM
