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.

28、 ISO and IEC technical committees collaborate 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,

29、 ISO/IEC JTC1. In addition to developing International Standards, ISO/IEC JTC1 has created a Special Group on Functional Standardization (ISO/IEC JTC1/SGFS) for the processing of International Standardized Profiles. An International Standardized Profile is an internationally agreed, harmonized docum

30、ent which identifies a standard or group of standards, together with options and parameters, necessary to accomplish a function or set of functions. Draft International Standardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires a

31、pproval by at least75% of the national bodies casting a vote. S-liaison may be established with JTC1/SGFS by specialized organizations involved in the work of functional standardization. This part of ISO/IEC ISP10609 was prepared with the collaboration of the following S-liaisons: Asia-Oceania Works

The context o

38、f Functional Standardization is one area in the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms. A profile defines a combination of base standards that collectively perform a specific well-defined IT function. Pr

39、ofiles standardize the use of options and other variations in the base standards, and provide a base 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 int

40、eroperability. 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 recognized test methods. The development and widespread acceptance of tests based on this and other ISPs is crucial to the successful re

41、alization of this goal. ISO/IEC ISP10609 consists of several parts, of which this is part12. Parts1 to4 of ISO/IEC ISP10609 specify profile requirements that are subnetwork-independent, for each of the transport groups TB, TC, TD and TE, respectively. There are further parts which specify subnetwork

42、-dependent and media-dependent requirements. In addition, for each individual profile there is a part of ISO/IEC ISP10609 which identifies the specific requirements of that profile, making reference to appropriate material from the relevant subnetwork-independent and subnetwork-dependent parts. This

43、 part identifies the specific requirements for profile TC51. 1 Scope 1.1 General This International Standardized Profile is applicable to End Systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI standards, which collectively provid

44、e the connection-mode Transport Service using the connection-mode Network Service. This part of ISO/IEC ISP10609 defines the TC51 profile which is applicable to the provision of the OSI connection-mode Transport Service using the OSI connection-mode Network Service in an End System attached to a CSM

45、A/CD LAN subnetwork. 1.2 Position within the taxonomy The taxonomy of profiles is defined in ISO/IEC TR10000-2. This part of ISO/IEC ISP10609 defines theprofile: TC51, Connection-mode Transport Service over connection-mode Network Service over CSMA/CD LAN subnetworks. 1.3 Scenario Figure 1 illustrat

46、es the configurations of systems to which the TC51 profile is applicable. Figure 1 Scenario of applicability of the TC51 profileISO/IECISP10609-12:1994(E) 2 BSI 08-1999 The TC51 profile specifies the required functions from the supporting protocol stack shown in Figure 2 below. This profile does not

47、 specify the required functions for relays. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC ISP10609.
