11、30-en. ii Rec. ITU-T G.9962 (2014)/Cor.1 (11/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a pe
12、rmanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, estab
13、lishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary sta
14、ndards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Re
15、commendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalent
16、s are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed
17、Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had recei
18、ved notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr

Annex C is introduced by this corrigendum, but it not shown with revision marks for readability purposes. 1 Scope This Recommendation specifi
24、es the physical and data link layer management for the ITU-T G.996x-series home networking transceiver specifications.

27、ions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendation

32、2, Amendment 8 (2014), Device data model for TR-0691. 3 Definitions 3.1 Terms defined elsewhere None. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 client: An application entity distinguished in the network by its unique address (e.g., MAC address).
33、3.2.2 domain: A part of an ITU-T G.996x home network comprising the domain master and all those nodes that are registered with the same domain master. In the context of this Recommendation, use of the term “domain“ without a qualifier means “ITU-T G.996x domain“, and use of the term “alien domain“ m
34、eans “non-ITU-T G.996x domain“. Additional qualifiers (e.g., “power-line“) may be added to either “domain“ or “alien domain“. 3.2.3 domain master (DM): A node that manages (coordinates) all other nodes of the same domain (i.e., assigns bandwidth resources and manages user priorities). A node with do
35、main master capabilities has all the capabilities of an endpoint node and may act as a relay node. 3.2.4 endpoint node: This term is used in this Recommendation according to the context to differentiate between the domain master node functionalities and non-domain master node functionalities. 3.2.5
36、global master (GM): A function that provides coordination between different domains (such as communication resources, priority setting, policies of domain masters and crosstalk mitigation). A global master may also convey management functions initiated by the remote management system (e.g., the Broa
37、dband Forum CPE WAN management protocol) to support broadband access. 3.2.6 home network: Two or more nodes that can communicate with each other either directly or through a relay node at the physical layer, or through an inter-domain bridge above the physical layer. A home network consists of one o
38、r more domains. In the context of this Recommendation, use of the term “home network“ means “ITU-T G.9960 home network“. Use of the term “alien home network“ means “non-ITU-T G.9960 home network“. Use of the term “network“ without a qualifier means any combination of “ITU-T G.9960 home network“, “no
39、n-ITU-T G.9960 home network“ and “access network“. Use of the term “alien network“ means any combination of “non-ITU-T G.9960 home network“ and “access network“. 3.2.7 logical (functional) interface: An interface in which the semantic, syntactic and symbolic attributes of information flows are defin
40、ed. Logical interfaces do not define the physical properties of signals used to represent the information. It is defined by a set of primitives. 3.2.8 medium: A wire-line facility, of a single wire class, allowing physical connection between nodes. Nodes connected to the same medium may communicate
41、on the physical layer, and may interfere with each other unless they use orthogonal signals (e.g., different frequency bands, different time periods). 3.2.9 node: Any network device that contains an ITU-T G.9960 transceiver. In the context of this Recommendation, use of the term “node“ without a qua
42、lifier means “ITU-T G.9960 node“, and use _ 1 See also http:/www.broadband-forum.org/cwmp/tr-181-2-8-0.html for the root object definitions. Rec. ITU-T G.9962 (2014)/Cor.1 (11/2016) 3 of the term “alien node“ means “non-ITU-T G.9960 node“. Additional qualifiers (e.g., “relay“) may be added to either
43、 “node“ or “alien node“. 3.2.10 reference point: A location in a signal flow, either logical or physical, that provides a common point for observation and/or measurement of the signal flow. 3.2.11 registration: The process used by a node to join the domain. 4 Abbreviations and acronyms This Recommen

46、ure A model of the ITU-T G.9960 management, control, and security (MCS) architecture is depicted in Figure 6-1. The model consists of various entities located either within nodes, within a domain, or external to the domain. MCS entities provide management, control, and security of the layer they res
47、ide in as well as services and interfaces to enable MCS communications. The structure of MCS begins with the layers of the node; the physical (PHY) layer and the data link layer (DLL). Each of these has a specific MCS entity. Above these in the MCS hierarchy, but still within Layer 2, is the node ma
48、nagement entity (NME), which is responsible for managing the nodes overall functions. Outside of the node are two entities that reside in the same domain as the node. 4 Rec. ITU-T G.9962 (2014)/Cor.1 (11/2016) These are the security controller entity (SCE) and the domain master management entity (DM
49、ME). These manage and control their specific areas of responsibility (e.g., security for the SCE) within the domain. These two entities are still within Layer 2 as they are solely functioning to facilitate Layer 2 activities. These two entities are considered to operate at the domain level, unlike the node located ones that operate at the node or device level. The next entity is the global master entity (GME). This entity is defined as e
