9、ocal and Metropolitan Area Networks: Media Access Con-trol (MAC) Bridges - Amendment 2: Bridging of IEEE 802.16.This document amends IEEE Std 802.1D to support bridging of the IEEE 802.16 medium access control. As of the approval date, the current applicable version of IEEE Std 802.1D is IEEE Std 80
10、2.1D-2004, as amended by IEEE 802.17a-2004 and IEEE 802.16k-2006.Scope: The scope of this project is limited to amending 802.1D to support Bridging of the IEEE 802.16 MAC. This involves: (a) Adding one subclause to Clause 6 of 802.1D describing the service interface mapping between the Internal Subl
11、ayer Service and the 802.16 MAC service; (b) minor changes elsewhere in the document as needed to accommodate support of the additional MAC, including priority mapping in Clause 7 and the PICS Proforma in Annex A.Purpose: The purpose is to amend the 802.1D transparent bridge standard in recognition
12、of the 802.16 Media Access Control (MAC).ParticipantsThe amendment and corrigendum were developed by the IEEE 802.16 Working Group on Broadband Wireless Access, which develops the WirelessMAN Standard for Wireless Metropolitan Area Networks.IEEE 802.16 Working Group OfficersRoger B.

Four editing instructions are used: chang
22、e, delete, insert, and replace. Change is used to make small corrections in existing text or tables. The editing instruction specifies the location of the change and describes what is being changed by either by using strikethrough (to remove old material) or under-score (to add new material). Delete
23、 removes existing material. Insert adds new material without disturbing the exist-ing material. Insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Replace is used to make large changes in existing text, subclauses, tables, or figures by removing
24、 existing material and replacing it with new material. Editorial notes will not be carried over into future editions because the changes will be incorporated into the base standard.2.

30、 Std 802.3 clause 2.The 802.16 MAC CPS presents a connection-oriented MAC service. The 802.3 packet CS utilizes this service to present the 802.3 service.
