Commen
13、ts on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should
14、 be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE a
15、nd the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any person who would
16、 like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group.

Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may
23、be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at lea
24、st every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable 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 late
25、st edition of any IEEE standard. In order to determine whether a given document is the current edition and whether it has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ ieeexplore.ieee.org/browse/standards/collection/ieee or contact IEEE a

Patents Attention is called to the possibility that implementation of this standard may require use of subject matter covered by patent rights. By publication of this standard, no position is taken by the IEE
28、E with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE- SA Website at http:/standards.ieee.org/about/sasb/patcom/
29、patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants desiring to o
30、btain such licenses. Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or deter
31、mining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the
32、 risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from the IEEE Standards Association.6 Copyright 2017 IEEE. All rights reserved.

42、u Yuan Daidi Zhong8 Copyright 2017 IEEE. All rights reserved. Introduction During the history of IEEE 802, several different MAC types have been developed, all of which have a core of functionality that is common to IEEE 802 MACs in general, but all of which also provide functionality that extends b
43、eyond that common core. An example can be found in the way priority information is conveyed in different MACs; some have no means of conveying priority, some can convey two different priority code points, some can convey eight priority code points. While such differences are not an issue in a Local
44、Area Network (LAN) that employs a single MAC technology, they can become an issue in LANs where more than one MAC technology is employed, for example in Bridged LANs. It was therefore important at an early stage of MAC Bridge development to develop a clear definition of the MAC Service that would fa
45、cilitate the definition of a common Bridging technology that could apply to all MAC types. The MAC Service definition was first standardized as ISO/IEC 15802-1:1995 B3. When the ISO/IEC standard reached its 5-year revision point, IEEE 802 was asked to take over the document and revise it to reflect
46、changes since publication. This revision emphasizes the fundamental relayable nature of the MAC Service provided to end stations by defining it in terms of the service, common to bridges and end stations, previously documented as the Internal Sublayer Service (ISS) in IEEE Std 802.1D. In addition to
47、 the material that was contained in ISO/IEC 15802-1, this standard documents the ISS that was originally defined in IEEE Std 802.1D. This standard contains state-of-the-art material. The area covered by this standard is undergoing evolution. Revisions are anticipated within the next few years to cla
48、rify existing material, to correct possible errors, and to incorporate new related material. Information on the current revision state of this and other IEEE 802 standards may be obtained from Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USA This introduction is not part of IEEE Std 802.1AC-2016, IEEE Standard for Local and metropolitan area networks Media Access Control (MAC) Service Definition.
