National bodies that are members
28、 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 collaborate in fields of mutual interest. Other international organi
29、zations, 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 developing International Standards, ISO/IEC JTC1 has created a Special G
30、roup on Functional Standardization (ISO/IEC JTC1/SGFS) for the processing 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
31、 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 approval by at least75% of the national bodies casting a vote. S-liaison may be established with JTC 1/
32、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 Workshop (AOW); European Workshop for Open Systems (EWOS); Open Systems Environment Implementors Workshop
33、(OIW). ISO/IEC ISP 10609 consists of several parts, under the general title Information technology International Standardized Profiles TB, TC, TD and TE Connection-mode Transport Service over connection-mode Network Service: Part 1: Subnetwork-type independent requirements for Group TB; Part 2: Subn

38、ntroduction This International Standardized Profile (ISP) is defined in accordance with the principles specified by ISO/IEC Technical Report10000, “Information technology Framework and taxonomy of International Standardized Profiles”. The context of Functional Standardization is one area in the over
39、all 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. Profiles standardize the use of options and other vari
40、ations 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 interoperability. One of the most important roles for a
41、n 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 realization of this goal. ISO/IEC ISP 10609 consists o
42、f several parts, of which this is part14. 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-dependent and media-dependent requirements. In add
43、ition, 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 part identifies the specific requirements for prof
44、ile TC53. 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 provide the connection-mode Transport Service using the c
45、onnection-mode Network Service. This part of ISO/IEC ISP 10609 defines the TC53 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 Token Ring LAN subnetwork. 1.2 Position within the ta
46、xonomy The taxonomy of profiles is defined in ISO/IEC TR10000-2.
