9、e 20 Switzerland International Standard ISO/IEC 8802-2 : 1998 IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Com- mission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in th
10、e development of International Standards through technical committees estab- lished by the respective organization to deal with particular fields of technical activity. IS0 and IEC techni- cal committees collaborate in fields of mutual interest. Other international organizations, governmental and no
11、n-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bod- ies for vot
12、ing. Publication as an International Standard requires approval by at least 75% of the national bod- ies casting a vote. International Standard ISO/IEC 8802-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Informution technology, Subcommittee SC 6, Telecommunications and information exchan

20、 (OSI) Basic Reference Model (ISOIIEC 7498-1 : 1994). The access standards define seven types of medium access technologies and associated physical media, each appropriate for particular applications or system objectives. Other types are under investigation. The International Standards defining the
21、access technologies are as follows: a) ISOIIEC 8802-3, utilizing carrier sense multiple access with collision detection (CSMNCD) as the b) ISOIIEC 8802-4, utilizing token passing bus as the access method. c) ISOIIEC 8802-5, utilizing token passing ring as the access method. d) ISOAEC 8802-6, utilizi

23、as the accessmethod. access method. ance (CSMNCA) as the access method. ISOiEC TR 8802-1, Overview of Local Area Network Standards, provides an overview of the series of ISO/ IEC 8802 standards. ISO/IEC 8802-2, Logical Link Control, is used in conjunction with the medium access standards to provide
24、the data link layer service to network layer protocols. ISOAEC 15802-1, Medium Access Control (MAC) service definition, specifies the characteristics of the com- mon MAC Service provided by all IEEE 802 LAN MACs. The service is defined in terms of primitives that can be passed between peer service u
25、sers, their parameters, their interrelationship and valid sequences, and the associated events of the service. ISOIIEC 15802-2, LAN/MAN Management, defines an OS1 management-compatible architecture, and ser- vices and protocol elements for use in a LANMAN environment for performing remote management
26、. ISOIIEC 10038, Media Access Control (MAC) bridges, specifies an architecture and protocol for the intercon- nection of IEEE 802 LANs below the level of the logical link control protocol (to be renumbered 15802-3). ISOIIEC 15802-4, System Load Protocol, specifies a set of services and protocol for
27、those aspects of man- agement concerned with the loading of systems on IEEE 802 LANs. ISOlIEC 15802-5, Remote Media Access Control (MAC) bridging, specifies extensions for the interconnec- tion, using non-LAN communication technologies, of geographically separated IEEE 802 LANs below the level of th
28、e logical link control protocol. Copyright Q 1998 IEEE.

Members of the committ
29、ees serve volun- tarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in par
30、ticipating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthe
31、rmore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirm
32、ation. When a document is more than five years old and has not been reaffirmed, it is rea- sonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE
33、Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasional
34、ly questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all
35、 concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to pro- vide an instant response to interpretation requests except in those cases where t
36、he matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O.
