10、REWORD 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 permanent organ of ITU. ITU-T is responsible for studyi
11、ng 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, establishes the topics for study by the ITU-T study groups
12、 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 standards are prepared on a collaborative basis with ISO
13、 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 Recommendation may contain certain mandatory provisions
14、 (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 equivalents are used to express requirements. The use of such w
15、ords does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention 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 c
16、oncerning 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 not received notice of intellectual property, protected b
17、y 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/.

43、information modelling Figure 1 describes the relationship between the scope of this Recommendation and the definition of management information models. Figure 1 Scope of ITU-T G.7718/Y.1709 6.2 Relationship to the ASON architecture This Recommendation contains a management framework for ASON control
44、 planes, as specified in ITU-T G.8080. The ITU-T G.8080 reference architecture describes: 1) functional components of the control plane, including abstract interfaces and primitives; 2) interactions between call controller components; 3) interactions among components during connection set-up; 4) fun
45、ctional components that transform the abstract component interfaces into protocols on external interfaces. The ITU-T G.8080 control plane functional components manipulate transport network resources in order to set up, maintain, and release calls and connections. Generically, every ITU-T G.8080 cont
46、rol plane component has a set of special interfaces to allow for monitoring of the component operation, for dynamically setting policies, and for affecting internal behaviour. These interfaces are not mandatory and are provided on specific components only where necessary. Components are not assumed
47、to be statically distributed. Rec. ITU-T G.7718/Y.1709 (07/2010) 5 6.3 Relationship to technology-specific Recommendations The architectural specifications and functional requirements contained in ITU-T G.8080 are applicable to connection-oriented circuit or packet transport networks, as defined in
48、ITU-T G.805. 6.4 Relationship to the TMN architecture This Recommendation adheres to the TMN principles specified in ITU-T M.3010. ITU-T M.3010 defines the logical layered architecture concept for organizing management functionality. The logical layers of interest in this Recommendation include the
49、element management layer, the network management layer and the service management layer. As noted in ITU-T M.3010, management objects defined for one layer may be used in others. Any management object may be used by any interface that requires it. The element management layer is concerned with the information that is required to manage a network element (NE). This refers to the information required to manage the network element function (NEF), the control plane func
