33、:1995(E) BSI 12-1999 1 Introduction ISO/IEC ISP 10608 is defined in accordance with the principles specified by ISO/IEC TR10000. The context of Functional Standardization is one area in the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, an

34、d registration mechanisms. A profile defines a combination of base standards that collectively perform a specific well-defined IT function. Profiles standardize the use of options and other variations in the base standards, and provide a basis for the development of uniform, internationally recogniz

35、ed system tests. ISPs are produced not simply to “legitimize” a particular choice of base standards and options, but to promote real system interoperability. One of the most important roles for an ISP is to serve as the basis for the development (by organizations other than ISO and IEC) of internati

36、onally recognized test methods. The development and widespread acceptance of tests based on this and other ISPs is crucial to the successful realization of this goal. ISO/IEC ISP 10608 consists of several parts, of which this is part6. ISO/IEC ISP 10608-1 specifies the profile requirements which are

37、 independent of the subnetwork and media. There are further parts which specify subnetwork-dependent and media-dependent requirements. In addition, for each individual profile, there is a part of ISO/IEC ISP10608 which identifies the specific requirements of that profile, making reference to appropr

38、iate material from part1and from the subnetwork-dependent parts. 1 Scope 1.1 General ISO/IEC ISP 10608 is applicable to end systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI base standards that collectively provide the connectio

39、n-mode Transport Service using the connectionless-mode Network Service. This part of ISO/IEC ISP 10608 is applicable to the provision of the connection-mode Transport Service in end systems attached to an FDDI LAN subnetwork from which the standardized connectionless-mode Network Service can be made

40、 available. 1.2 Position within the taxonomy The taxonomy of OSI profiles is defined in ISO/IEC TR 10000-2.
