Comments on standardsComm
13、ents 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 be in the form of a
14、 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 and the members of it
15、s 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 like to participate
16、 in revisions to an IEEE standard is welcome to join the relevant IEEE working group.Comments on standards should be submitted to the following address:Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USALaws and regulations Users of IEEE Standards documents should consult all a

By publication of this standard, no position is taken by the IEEE with respect to the existence or
28、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/patents.html. Letters of Assurance m
29、ay 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 obtain such licenses.Essential Patent
30、 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 determining whether any licensing terms or
31、 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 risk of infringement of such rights,
32、 is entirely their own responsibility. Further information may be obtained from the IEEE Standards Association.5Copyright 2017 IEEE.

All rights reserved.IntroductionDuring the history of IEEE 802, several different MAC types have been developed, all of which have a c
42、oreof functionality that is common to IEEE 802 MACs in general, but all of which also provide functionalitythat extends beyond that common core. An example can be found in the way priority information isconveyed in different MACs; some have no means of conveying priority, some can convey two differe
43、ntpriority code points, some can convey eight priority code points.While such differences are not an issue in a Local Area Network (LAN) that employs a single MACtechnology, they can become an issue in LANs where more than one MAC technology is employed, forexample in Bridged LANs. It was therefore
44、important at an early stage of MAC Bridge development todevelop a clear definition of the MAC Service that would facilitate the definition of a common Bridgingtechnology that could apply to all MAC types.The MAC Service definition was first standardized as ISO/IEC 15802-1:1995 B3. When the ISO/IECst
45、andard reached its 5-year revision point, IEEE 802 was asked to take over the document and revise it toreflect changes since publication. This revision emphasizes the fundamental relayable nature of the MACService provided to end stations by defining it in terms of the service, common to bridges and
46、 end stations,previously documented as the Internal Sublayer Service (ISS) in IEEE Std 802.1D. In addition to thematerial that was contained in ISO/IEC 15802-1, this standard documents the ISS that was originallydefined in IEEE Std 802.1D. This standard contains state-of-the-art material. The area c
47、overed by thisstandard is undergoing evolution. Revisions are anticipated within the next few years to clarify existingmaterial, to correct possible errors, and to incorporate new related material.
