CSA ISO/IEC 9314-26:04 (R2019)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved as a National Standard of Canada by the Standards Council of Canada. Scope This part of ISO/IEC 9314 contains the abstract test suite for the Fibre Distributed Data Interface (FDDI) token ring Media Access Control (MAC) layer protocol. This test suite was developed based on the principles defined in OSI Conformance Testing Methodology and Framework (ISO/IEC 9646) and written in Tree and Tabular Combined Notation (TTCN), and intended for testing conformance to the MAC standard (ISO/IEC 9314-2:1989) of any FDDI stations. The test methodology is the "remote single layer test" as described in ISO/IEC 9646. The abstract test scripts specify the MAC layer Protocol Data Units (PDU) to be exchanged between the two MAC entities, the MAC on the tester and the MAC on the Implementation Under Test (IUT). The tester is called the Lower Tester (LT). The test suite does not require use of any higher layer protocols, nor does it assume existence of Logical Link Control (LLC) layer implementation on the IUT. It expects, however, that the Station Management (SMT) function is available on the IUT. Since MAC itself does not originate any data frames, the tester uses SMT to test the processing capability of MAC by sending frames to SMT and observing the SMT originated response frames. The testing is expected to be conducted in a controlled environment with a minimum configuration (figure 1): a token ring with two stations, one being the LT and the other the IUT.
