The requirements for dedicated token ring
13、 (DTR) operation are specified, including the changes and additions to the Medium Access Control (MAC) layer to provide for an additional full-duplex mode of operation (switching), and for interconnection of shared LAN segments to switch ports. Also specified are the characteristics of a fibre optic
14、 interface for connecting a 4 Mbis or 16 Mbit/s token ring sta- tion to the trunk coupling unit (TCU) of a token ring, including station, port, and channel require- ments.

20、el (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 access technologies are as
21、 follows: a) b) c) d) e) f) g) ISO/IEC 8802-3, utilizing carrier sense multiple access with collision detection (CSMNCD) as the access method. ISOIIEC 8802-4, utilizing token passing bus as the access method. ISOIIEC 8802-5, utilizing token passing ring as the access method. ISOIIEC 8802-6, utilizin
22、g distributed queuing dual bus as the access method. ISODEC 8802-9, a unified access method offering integrated services for backbone networks. ISO/IEC DIS 8802-1 1, a wireless LAN utilizing carrier sense multiple access with collision avoid- ance (CSMAICA) as the access method. ISO/IEC DIS 8802-12,
23、 utilizing Demand Priority as the access method. ISO/IEC 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 the data link layer s
24、ervice to network layer protocols. ISOIIEC 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 users, their paramete
25、rs, their interrelationship and valid sequences, and the associated events of the service. ISO/IEC 15802-2, UNMAN Management, defines an OS1 management-compatible architecture, and ser- vices and protocol elements for use in a LANMAN environment for performing remote management. ISOAEC 10038, Media
26、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). ISO/IEC 15802-4, System Load Protocol, specifies a set of services and protocol for those aspects of man- a
27、gement concerned with the loading of systems on IEEE 802 LANs. ISOIIEC 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 the logical link control p

29、 (IEEE-SA) Standards Board. Members of the committees serve voluntarily 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 outsid
30、e 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 Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services r
31、elated 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 developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at
32、 least every five years for revision or reaffirmation. 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 determin
33、e that they have the latest edition of any IEEE 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
34、supporting comments. Interpretations: Occasionally 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. S
35、ince 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. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an
36、 instant response to interpretation requests except in those cases where the matter has previously received formal consideration.
