National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees col

26、laborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison 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 develop

27、ing International Standards, ISO/IEC JTC1 has created a Special Group on Functional Standardization for the elaboration of International Standardized Profiles. An International Standardized Profile is an internationally agreed, harmonized document which identifies a standard or group of standards, t

28、ogether with options and parameters, necessary to accomplish a function or a set of functions. Draft International Standardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires approval by at least75% of the national bodies casting

29、a vote. International Standardized Profile ISO/IECISP10613-2 was prepared with the collaboration of Asia-Oceania Workshop (AOW); European Workshop for Open Systems (EWOS); Open Systems Environment Implementors Workshop (OIW).

The context of Functional Standardization is one area in the overall field of Informatio

40、n Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms. Aprofile 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 stand

41、ards, and provide a basis for the development of uniform, internationally recognized 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 th

42、e basis for the development (by organizations other than ISO and IEC) of internationally recognized 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

43、is part2. ISO/IECISP10613-1 specifiesthe profile requirements that are subnetwork-independent. There are further parts which specify subnetwork-dependent and media-dependent requirements. In addition, foreach individual profile there is a part of ISO/IECISP10613 which identifies the specific require

44、ments of that profile, making reference to appropriate material from part1 and from the subnetwork dependent parts of ISOIECISP10613. 1 Scope This International Standardized Profile is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It

45、 specifies a combination of OSI base standards that collectively provide a Network Relay function for the connectionless-mode Network Service. This part of ISO/IECISP10613 specifies subnetwork-type dependent requirements applicable to an interworking unit attached to a LAN and using the ISO8802-2 LL

46、C type1 protocol, irrespective of the LAN medium. The operation of an interworking unit may involve relaying from onesubnetwork to another, and those subnetworks neednot be of the same type. This part of ISO/IECISP10613 applies only to communication over those subnetworks which are LANs using ISO880

47、2-2 LLC type1. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this International Standardized Profile. At the time of publication, the editions indicated were valid. All documents are subject to revision, and parties

48、to agreements based on this International Standardized Profile are warned against automatically applying any more recent editions of the documents listed below, since the nature of references made by ISPs to these documents is that they may be specific to a particular edition.
