The relationship between this International Standard and the other members of the family is shown below. (The numbers
11、 in the gure refer to ISO/IEC Standard numbers.) This family of International Standards deals with the Physical and Data Link layers as dened by the ISO/ IEC Open Systems Interconnection (OSI) Basic Reference Model (ISO/IEC 7498-1 : 1994). The access standards dene seven types of medium access techn
12、ologies and associated physical media, each appropriate for particular applications or system objectives. Other types are under investigation. The International Standards dening the access technologies are as follows: a) ISO/IEC 8802-3, utilizing carrier sense multiple access with collision detectio
13、n (CSMA/CD)as the access method. b) ISO/IEC 8802-4, utilizing token passing bus as the access method. c) ISO/IEC 8802-5, utilizing token passing ring as the access method. d) ISO/IEC 8802-6, utilizing distributed queuing dual bus as the access method. e) ISO/IEC 8802-9, a unied access method offerin
14、g integrated services for backbone networks. f) ISO/IEC DIS 8802-11, a wireless LAN utilizing carrier sense multiple access with collision avoid- ance (CSMA/CA) as the access method. g) ISO/IEC 8802-12, utilizing Demand Priority as the access method. ISO/IEC TR 8802-1, Overview of Local Area Network
15、 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 the data link layer service to network layer protocols. ISO/IEC 15802-1, Medium Access Control (MAC) service denition, s
16、pecies the characteristics of the com- mon MAC Service provided by all IEEE 802 LAN MACs. The service is dened in terms of primitives that can be passed between peer service users, their parameters, their interrelationship and valid sequences, and the associated events of the service. ISO/IEC 15802-
17、2, LAN/MAN Management, denes an OSI management-compatible architecture, and ser- vices and protocol elements for use in a LAN/MAN environment for performing remote management. ISO/IEC 15802-3, Media Access Control(MAC) Bridges, species an architecture and protocol for the inter- connection of IEEE 8
18、02 LANs below the level of the logical link control protocol. ISO/IEC 15802-4, System Load Protocol, species a set of services and protocol for those aspects of man- agement concerned with the loading of systems on IEEE 802 LANs.

21、rdsdocuments are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed
22、 within IEEE represent a con- sensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Stand
23、ard 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. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through de
24、velopments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every ve years for revision or reafrmation. When a document is more than ve years old and has not been reafrmed, it is reasonable to conclude that its contents, al
25、though still of some value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they have the latest edi- tion of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership afliation with IEE
26、E. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to spe- cic applications. When the need for inter
27、pretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. F
28、or this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpre- tation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretat
