ITU-T M.3071 (01/2018) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs)

9、. 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 basis. The World Telecommunication St

10、andardization 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 Resolution 1. In some areas of informat

11、ion 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 and a recognized operating agency.

12、 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 met. The words “shall“ or some ot

13、her 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 attention to the possibility that the practice or imple

14、mentation 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 Recommendation development process

15、. 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 information and are therefore strongly u

It describes the composition of a cloud-based network management functional architecture, explains the functions of each component in the architecture, and also introduces the relationship be

20、tween these components. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other reference

24、n architectural concept that represents telecommunication equipment (or groups/parts of telecommunication equipment) and supports equipment or any item or groups of items considered belonging to the telecommunications environment that performs network element functions (NEFs). 3.2 Terms defined in t

25、his Recommendation This Recommendation defines the following terms: 3.2.1 cloud-based network management: Cloud-based network management is to perform network management functions using cloud-computing technology, and it can also be used to manage both traditional telecommunication networks and/or c

26、loud computing infrastructures. 2 Rec. ITU-T M.3071 (01/2018) 3.2.2 management service analysis function: The management service analysis function provides the ability to analyse each management service in the network management. Each management service is registered in this analyser function, and a

27、ll related information about this service is analysed and stored for future use. 3.2.3 management service composing function: The management service composing function provides the ability of composing several small management functions into a new complex management service, so that a new type of ma

28、nagement functionality can be easily provided without having to change the implementation of the component management functions. 3.2.4 management service deployment function: The management service deployment function provides the ability of deploying required services for a management task. Each ma

29、nagement task may need the support of multiple management services, and for those services which are not ready for use, they will appropriately be deployed into some virtualized resources on the cloud infrastructure. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations a
