1、National Standard of CanadaCAN/CSA-ISO/IEC 9314-21:04(ISO/IEC 9314-21:2000)International Standard ISO/IEC 9314-21:2000 (first edition, 2000-10) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 9314-21:04, which has been approved as a NationalStandard of Canada by the Standa

3、uspices 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. CS
4、A 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 governments
5、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 supporting
6、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 ac
7、tivities. 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 addit
8、ion 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 serv
9、ice 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 toCanadian
10、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 st
11、andardization 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 in
12、ternational 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 collect
13、ive 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 nat
14、ional 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 th
15、e 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 prepari

32、trotechnical Commission) form thespecialized system for worldwide standardization. National bodies that are members of ISO or IEC participate inthe development of International Standards through technical committees established by the respectiveorganization to deal with particular fields of technica

Other international organizations, governmental and non-governmental, in liaison withISO and IEC, also take part in the work.2) In the field of information technology, ISO and IEC have established a joint technical

40、 Data Interface (FDDI) is intended for use in a high performance generalpurpose multi-station network and is designed for efficient operation with a peak data rate of100 Mbit/s. It uses a Token Ring Architecture with optical fibre as the transmission medium.FDDI provides for hundreds of stations ope
41、rating over an extent of tens of kilometres.FDDI Physical Layer Protocol (PHY) specifies the upper sublayer of the Physical Layer for theFDDI, including the data encode/decode, framing and clocking, as well as the elasticity buffer,smoothing and repeat filter functions. This Abstract Test Suite (ATS
42、) provides a conformancetest for FDDI PHY. FDDI PHY, however, does contain several state machines and implementsa protocol at the level of FDDI code symbols. The only physical quantity that must bemeasured in this conformance test is frequency. The PHY ATS cannot use the Tree andTabular Combined Not
43、ation (TTCN) language specified in ISO 7496 and a notation isdeveloped in the PHY ATS for specifying test patterns and expected results in terms of FDDIcode symbol strings.Four other standards in conjunction with this standard provide a complete conformance test ofan FDDI station:a) An ATS for FDDI
44、Physical Medium Dependent (PMD) that provides a conformance test forFDDI PMD. PMD specifies the optical interface of FDDI stations. PMD is not a protocolstandard and this ATS requires the measurement of physical quantities such as opticalpower, wavelength and signal jitter. The PMD ATS differs from
45、the methodology of higherlevel protocol conformance tests written using the TTCN, because the TTCN notation doesnot provide a suitable vehicle for Physical Layer testing, where there is no concept of aprotocol data unit and where physical quantities must be measured.b) An ATS for FDDI Media Access C
46、ontrol (MAC) that provides a conformance test for FDDIMAC. MAC specifies the lower sublayer of the Data Link Layer for FDDI. It specifiesaccess to the medium, including addressing, data checking and data framing. MAC alsospecifies the receiver and transmitter state machines. Since MAC is a protocol
47、that dealsprimarily with complete PDUs, the TTCN language is used to specify MAC protocol tests.Provisions of MAC, however, require high resolution timing that may be difficult to achievein commercial protocol testers.c) An ATS for FDDI Station Management (SMT) that provides a conformance test for F
48、DDISMT. SMT specifies the local portion of the system management application process forFDDI, including the control required for proper operation of an FDDI station in an FDDIring. SMT provides services such as connection management, station insertion andremoval station initialisation, configuration
49、 management and fault recovery, communi-cations protocol for external authority, scheduling policies and the collection of statistics.SMT interacts with PMD, PHY and MAC. Therefore, an ATS for portions of SMT that useMAC PDUs can be specified in TTCN, while other portions require other approaches.d) A Protocol Implementation Conformance Statement (PICS) proforma for FDDI thatprovides a statement of the mandatory and optional requirements of each of the four FDDIbase standards. The PICS proforma is used to identify requirem
