6、ndation M.3060/Y.2401 Principles for the Management of Next Generation Networks Summary This Recommendation presents the management requirements, general principles and architectural requirements for managing Next Generation Networks (NGN) to support business processes to plan, provision, install, m

7、aintain, operate and administer NGN resources and services. This Recommendation defines concepts of the Next Generation Networks Management (NGNM) architecture, i.e., its business process view, functional view, information view, and physical views; and their fundamental elements. This Recommendation

8、 also describes the relationships among the architectural views and provides a framework to derive the requirements for the specification of management physical views from the management functional and information views. A logical reference model for partitioning of management functionality, the Log

9、ical Layered Architecture (LLA), is also provided. Source ITU-T Recommendation M.3060/Y.2401 was approved on 22 March 2006 by ITU-T Study Group 4 (2005-2008) under the ITU-T Recommendation A.8 procedure. Keywords Architecture, business process, conformance and compliance, function block, interface,

10、management function set (MFS), management functionality, management service, next generation networks management (NGNM), NGNM logical layered architecture (LLA), operations system (OS), operations systems component (OSC), reference point. ii ITU-T Rec.

11、nal Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. 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

12、 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 which, in turn, produce Recommendations on these topics. The approval o

13、f 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 and IEC. NOTE In this Recommendation, the expression “Administration“ i

14、s 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 (to ensure e.g., interoperability or applicability) and compliance with

15、 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 words does not suggest that compliance with the Recommendation is required

16、 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 concerning the evidence, validity or applicability of claimed Intellectual

17、 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 by patents, which may be required to implement this Recommendation. Howeve
