National bodies that are members of ISO or IEC participate in the development of Inter

26、national Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison

27、 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, ISO/IEC JTC1. In addition to developing International Standards, ISO/IEC JTC1 has created a Special Group on Functional Standardization for the elaboration

28、 of International Standardized Profiles. An International Standardized Profile is an internationally agreed, harmonized document which identifies a standard or group of standards, together with options and parameters, necessary to accomplish a function or a set of functions. Draft International Stan

29、dardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires approval by at least 75 % of the national bodies casting a vote.

40、dardized Profile (ISP) is defined in accordance with the principles specified by ISO/IEC Technical Report 10000. The context of Functional Standardization is one area in the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration m

41、echanisms. 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 recognized system tests.

42、 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 internationally recognize

43、d tests. 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 10613 consists of several parts of which this is part 3. ISO/IEC ISP 10613-1 specifies the profile requirements that are subnetwork-independent.

44、 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 ISP 10613 which identifies the specific requirements of that profile, making reference to appropriate material from part 1 and from the su

45、bnetwork dependent parts of ISO/IEC ISP 10613. 1 Scope This International Standardized Profile is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI base standards that collectively provide a Network Rela

46、y function for the connectionless-mode Network Service. This part of ISO/IEC ISP 10613 specifies media-dependent requirements which are applicable to an interworking unit attached to an ISO/IEC 8802-3 CSMA/CD LAN subnetwork. The operation of an interworking unit may involve relaying from one subnetw

47、ork to another, and those subnetworks need not be of the same type. This part of ISO/IEC ISP 10613 applies only to communication over those subnetworks which are ISO/IEC 8802-3 CSMA/CD LANs. 2 Normative references The following documents contain provisions which, through reference in this text, cons
