The present document is part 3 of a multi-part deliverable covering the HIPERLANI2 Data Link Control (DLC)
13、Layer, as identified below: Part 1: Part 2: “Basic Data Transport Functions“; “Radio Link Control (RLC) sublayer“; Part 3: Part 4: “Profile for Business Environment“; “Extension for Home Environment“. Introduction The present document is a profile document, pointing at functions in the referenced HI
14、PERLANI2 documents. The referenced HIPERLANI2 documents are: Data Link Control (DLC) Layer (ETSI TS 10 1 76 1) Part 1: Part 2: Packet based Convergence Layer (ETSI TS 101 493) Part 1: Common Part 3 Basic Data Transport Functions i Radio Link Control (RLC) sublayer 2 Part 2: Ethernet Service Specific
15、 Convergence Sublayer 4 Physical Layer (ETSI TS 101 475 5) Network Management (ETSI TS 101 762 6) If a function is mandatory in a referenced document, it is also mandatory in the present document. If a function is optional in a referenced document, it may still be optional in the present document. I
16、n that case, nothing further is written in the present document. If a function is optional in a referenced document, it can be made mandatory in the present document. In these cases, it is clearly stated in the present document that the function has become mandatory. The words “mandatory“ and “optio
17、nal“ in the present document always mean that it is mandatory or optional to implement a function. ETSI 5 ETSI TS 1 O1 761 -3 V1.l.l (2000-09) 1 Scope The present document specifies the interoperability functions needed for a business environment. It contains functions of the Data Link Control Layer
18、, the Radio Link Control Sublayer, the Convergence Layer, the Physical Layer and Network Management specifications of HIPERLAN/2. It does not contain interoperability functions for communication over the fixed network. The present document is a profile document, selecting functions from the HIPERLAN
19、/2 basic specifications of the reference list. It is also a document survey since it refers to versions of the basic specifications and since the version number of the present document is negotiated during association and handover. A business environment is characterized by the following properties
20、for the present document: The fixed network is a Local Area Network (LAN) of the types Ethernet and IEEE802.1/2/3. The traffic type is data traffic that is handled connectionless but with priorities by the Ethernet. The amount of streaming services is small. Most of the data traffic goes between a t
21、erminal and the fixed network. The fixed LAN network is usually physically well protected since it is installed in restricted areas. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either spe
22、cific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. A non-specific reference to an ETS shall also be taken to refer to later versions pu

The tables also specify what optional parts in reference that shall not be implemented due to lack of negotiating possibilities. Optional parts in the basic specific

To summarize, the handover function is mandatory and shall be implemented. The functions direct 1inWdirect mode and

48、 (informative): Broadcasting and multicasting in combined I P/Ethernet- and Hiperlan 2 networks See references 7, lo. Layers above Ethernet, for example IP, requires broadcast and multicast for certain functions. Some types of such functions are network related such as address resolution protocol (A
49、RP), reverse address resolution protocol (RARP) and Dynamic Host Configuration Protocol (DHCP). Other types of such functions are end user related, for example broadcasting or multicasting of video and audio. All of these services are mapped to Ethernet frames with broadcast- or multicast addresses with the addition of a priority. What will happen in different situations is to a certain extent implementation specific. All broadcast frames coming from the fixed Ethernet go out over the air if the AP is a layer 2 machine, not analyzing what is
