ITU-T M.3160 (11/2008) i Recommendation ITU-T M.3160 Generic, protocol-neutral management information model Summary Recommendation ITU-T M.3160 provides a generic network information model. The model describ
6、es information object classes (IOCs) and their properties that are generic and useful to describe information exchanged across all interfaces defined in Recommendation ITU-T M.3010 TMN architecture. These generic managed object classes are intended to be applicable across different technologies, arc
7、hitecture and services. The managed object classes in this Recommendation may be specialized to support the management of various telecommunications networks. This Recommendation follows Recommendation ITU-T M.3020, management interface specification methodology on the analysis phase. The informatio
8、n models provided in this Recommendation are in a protocol-neutral manner, and can be mapped to multiple protocol-specific information models (design phase). Source Recommendation ITU-T M.3160 was approved on 13 November 2008 by ITU-T Study Group 2 (2009-2012) under Recommendation ITU-T A.8 procedur

ITU-T M.3160 (11/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and
10、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 worldwide basi
11、s. 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 in WTSA Resolu
12、tion 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 administration a
13、nd 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 provisions are m
14、et. 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 RIGHTS ITU draws attention to the possi
15、bility 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 outside of the R
16、ecommendation development process. As of the date of approval of this Recommendation, ITU had not 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 latest informa

20、eneric, protocol-neutral management information model 1 Scope This Recommendation provides a generic network information model. It identifies TMN object classes that are common to managed telecommunication networks, or are of a generic type that can be used to manage a network at a technology-indepe
21、ndent level, or are super-classes of technology-specific managed objects in a telecommunication network, or management support objects that are required for the management of the telecommunication network. These objects are relevant to information exchanged across standardized interfaces defined in
22、the b-ITU-T M.3010 TMN architecture. This Recommendation addresses generically the abstractions of those aspects of telecommunication resources (e.g., equipments, telecommunication services) required to manage the network. It also includes the abstractions related to the management services. b-ITU-T
23、 G.805, on the generic functional architecture of the connection-oriented transport network, and b-ITU-T G.809, on the functional architecture of connectionless layer networks, are used as the basis in developing the transport aspects of this model. The generic information model provided in this Rec
24、ommendation follows the ITU-T M.3020 interface methodology on the analysis phase, and they are developed in a protocol-neutral manner, which can be mapped to multiple protocol-specific information models. This Recommendation does not address abstractions relevant to technology-specific areas or impl
25、ementation-specific details. 1.1 Purpose 1.1.1 Interoperability There will be a variety of TMN conformant management systems and managed systems concerning many technology-specific areas, such as switching and transmission. One purpose of this Recommendation is to provide a vehicle for management in
26、teroperability between such systems. 1.1.2 Technology-independent management By introducing the concept of technology-independent management, it is possible to perform management of diverse equipment using common communication interfaces. In this manner, an “abstract“ view over a set of network-elem
27、ents can be achieved. 1.1.3 Facilitating information model development This Recommendation also provides a framework from which technology-specific information models may be developed. 1.2 Field of application This Recommendation captures the generally applicable requirements of the technology-indep
28、endent and technology-specific information models, as well as information relating to TMN management services. Through specialization, this Recommendation is applicable to technology-specific TMN information models. The mechanism for specialization is inheritance. 2 Rec. ITU-T M.3160 (11/2008) Even
29、though technology-specific models may be derived from this Recommendation, some of the generic managed object classes in this Recommendation are instantiable in order to provide interoperability between equipment supporting information models derived from this Recommendation and equipment that only
30、supports the information model in this Recommendation. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
