ITU-T G.9962 (2014)/Amd.1 (04/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, in
11、formation and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent 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
12、worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes 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
13、in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards 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 ad
14、ministration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory p
15、rovisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents 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 attentio
16、n to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed 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 ou
17、tside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received 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 late
18、st information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2015 All rights reserved.

31、y its unique address (e.g., MAC address). 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 dom
32、ain“, and use of the term “alien domain“ means “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 an
33、d manages user priorities). A node with domain 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-
34、domain master node functionalities. 3.2.5 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 th
35、e remote management system (e.g., the Broadband 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 physic
36、al layer. A home network consists of one or 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 combi
37、nation of “ITU-T G.9960 home network“, “non-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
38、 attributes of information flows are defined. 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 con
39、nected to the same medium may communicate 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 Recommenda
40、tion, use of the term “node“ without a qualifier 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.

41、ers (e.g., “relay“) may be added to either “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.

44、itecture and reference model 6.1 Architecture 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, c
45、ontrol, and security of the layer they reside 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
46、, but still within Layer 2, is the node management 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)/Amd.1 (04/2016) These are the security controller entity (SCE) a
47、nd the domain master management entity (DMME). 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 considere
48、d 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 external to the domain, performing management and control functions for all domains within a specific home network. Gl
49、obal master (GM) functions are logical and able to be distributed among its managed domain masters (DMs). As GM functions concern actions that span multiple domains within a common network, it is referenced as operating at the network level for logical representation of its place in the MCS hierarchy. This is an arbitrary assignment given the logical nature of the GM. Entities that perform functions above the security controller (SC) and the GM or, in its absenc
