Editorial Note The editing instructions contained in this amendment define how to mer

Three editing instructions are used: change, delete, and insert. Change is used to make a change to existing material. The editi

Changes to existing text may be clarified using strikeout markings to indicate removal of old material, and underscore markings to indicate addition of new material). Delete removes existing material. Insert add

32、s new material without changing the existing material. Insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Editing instructions, change markings, and this NOTE will not be carried over into future editions because the changes will be incorporated

33、 into the base standard. Changes are applied to the base text of IEEE Std 802.1Q-2005, as modified by those amendments that have been approved, but not incorporated into the base text of the standard, at the time that this amendment was approved, namely (in chronological order) IEEE Std 802.1ad, IEE

Support by IEEE Std 802.20 (MBWA) 6.7.2.1 Support by Wideband m

37、ode of IEEE Std 802.20 (MBWA) The Mobile Broadband Wireless Access Method for the IEEE 802.20 Wideband Mode is specified in 5.4 and Clause 6 through Clause 17 of IEEE Std 802.20. Clause 8 of the standard specifies the Wideband Mode Lower MAC Layer Frame structure and protocol procedures. Clause 7 sp

38、ecifies the Radio Link Sublayer protocol and Clause 6 defines the Services Sublayer of the Wideband Mode. Clause 11 defines the Connection Control Plane, which controls the state of the air-link by managing the states of individual Lower MAC Layer protocols, and by providing individual Lower MAC Lay

39、er protocols with operating parameters. The Basic Packet Consolidation Protocol (8.2 of IEEE Std 802.20) provides packet consolidation on the transmit side and provides packet de-multiplexing on the receive side. It provides an interface for the Radio Link Sublayer to transport user information from

40、 the Services Sublayer. For packets to be transmitted over the air interface (wireless medium) either from the Access Node (AN) or Access Terminal (AT), the Lower MAC Sublayer shall accept Radio Link Sublayer data and control packets and shall generate Lower MAC Sublayer control packets of its own.

41、For packets leaving the air interface (wireless medium) for the AN or AT, the Lower MAC Sublayer shall de-multiplex the received packets and shall deliver the payload to the Radio Link Sublayer. The Radio Link Sublayer shall deliver the payload to the Services Sublayer which includes support for dif

42、ferent IEEE802.3 frame based protocols. 6.7.2.1.1 Support for Internal Sublayer Service under Wideband Mode of IEEE Std 802.20 The destination_address, source_address, mac_service_data_unit, and user_priority parameters of the M_UNITDATA primitive are encoded as described in 6.6.2. The value of oper

43、PointToPointMAC (6.6.3) shall be TRUE. The value of MAC_Enabled shall be determined by the procedure described in 6.6.2. 1IEEE publications are available from the Institute of Electrical and Electronics Engineers, Inc., 445 Hoes Lane, Piscataway, NJ 08854, USA (http:/standards.ieee.org/). 2The IEEE

45、dging of IEEE 802.20 After the IEEE 802.20 AT has registered with the AN, authenticated, and performed capabilities negotiation, and after the stream is established to carry IEEE 802frames, then the value of the MAC_Operational parameter shall be determined by the procedure described in 6.6.2. Befor

46、ehand, the value of MAC_Operational shall be FALSE. Frame size limits are determined by IEEE Std 802.3. 6.7.2.2 Support by 625k-MC mode of IEEE Std 802.20 (MBWA) The Mobile Broadband Wireless Access Method for 625k-MC mode is specified in 5.5, Clause 18 through Clause 31, and Annex A of IEEE Std 802

47、.20. Clause 19 of the standard specifies 625k-MC Mode MAC Frame structure. Clause 23 specifies the MAC Protocol Sublayer function to implement the 625k-MC mode MAC service. Clause 25 specifies the L3 protocol and Clause 26 defines all the primitives used in 625k-MC Mode. The L3 protocol layer is mad

48、e up of components with distinct roles in supporting a connection across the air interface. The L3 Connection Management (CM) module provides an application level interface to the higher layer. The L3 protocol creates logical connections to transport the higher layer L4 data packets. The L3 Registra

49、tion Management (RM) module takes the L4 data packets provided by the higher layer (through L3 CM) and converts them into a form that can be sent over the air interface. On the receiving side, L3 RM converts packets received from the air interface back into network packets before giving them to L3 CM. Clause 26 defines the higher layer to L3 CM Interface Primitives for the service access point that shall be provided by L3 CM for the use of the higher layer. Clause 26 defines L3 CM to L4 Interface Primitives for the service access point pro
