11、the specialized system for worldwide standardization. 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 tec
12、hnical 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, ISO/IEC JTC1. D
13、raft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75%of the national bodies casting a vote. International Standard ISO/IEC 14766 was prepared by Joint Technical Co
14、mmittee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems. Annex A of this International Standard is for information only.iv blankBSISO/IEC14766:1997 BSI 09-1999 1 1 Scope This International Standard defines a mechanism which allows
15、 OSI upper layers (all session, presentation, and application entities) to operate over the Internet Transmission Control Protocol (TCP) without being aware that they are running on a TCP/IP internetwork. It provides similar functionality to ISO/IEC Transport Protocol Class4. It does not provide a g
16、ateway facility between Internet and OSI applications. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subje
17、ct to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. 2.1 International

The adaptation which

Systems, for which conformance to this International Standard is claimed, shall implement this adaptation mechanism when interconnecting OSI applications via Internet networks.
