13、4 ISO/IEC:2012 (E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Stand
14、ards 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 with ISO and
15、IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee i
16、s to prepare International Standards. Draft 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. ISO/IEC 14908-4 was prepared b
17、y CEN/TC 247 and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and IEC. ISO/IEC 14908 consists of the following parts, under the general title Information technology
18、 Control network protocol: Part 1: Protocol stack Part 2: Twisted pair communication Part 3: Power line channel specification Part 4: IP communication 14908-4 ISO/IEC:2012 (E) - 5 - Introduction This International Standard has been prepared to provide mechanisms through which various vendors of loca
19、l area control networks may exchange information in a standardised way. It defines communication capabilities. This International Standard is used by all involved in design, manufacture, engineering, installation and commissioning activities. The International Organization for Standardization (ISO)
20、and International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this International Standard may involve the use of patents held by Echelon Corporation The ISO and IEC take no position concerning the evidence, validity and scope of this patent ri
21、ght. The holder of this putative patent right has assured the ISO and IEC that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of the putative patent rights is regis
22、tered with the ISO and IEC. Information may be obtained from: Echelon Corporation, 4015 Meridian Avenue, San Jose, CA 94304, USA, phone +1-408- 938-5234, fax: +1-408-790-3800 http:/. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
23、patent rights other than those identified above. ISO and IEC shall not be held responsible for identifying any or all such patent rights. - 7 - INFORMATION TECHNOLOGY CONTROL NETWORK PROTOCOL Part 4: IP communication 1 Scope This International Standard specifies the transporting of the Control Netwo
24、rk Protocol (CNP) packets for commercial local area control networks over Internet Protocol (IP) networks using a tunnelling mechanism wherein the CNP packets are encapsulated within IP packets. It applies to both CNP nodes and CNP routers. The purpose of this International Standard is to insure int
