6、ENDATION M.3013 CONSIDERATIONS FOR A TELECOMMUNICATIONS MANAGEMENT NETWORK Summary The Telecommunications Management Network (TMN) is implemented to support management activities associated with telecommunication networks. This Recommendation introduces essential considerations needed to support ins
7、tallation and operation of a TMN based on the TMN principles, concepts and architecture, which are described in Recommendation M.30 1 O. Issues associated with evolution of new technologies for TMN applications are also identified. Background This Recommendation is based upon material extracted rom
8、Recommendation M.30 1 O (1 996). In this Recommendation the material has been updated, refined, and expanded to assist in the planning, design, implementation and operation of a TMN. Source ITU-T Recommendation M.3013 was prepared by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Re
9、solution No. 1 procedure on 4 February 2000. Keywords Architecture, Implementation guidelines, Telecommunications management network (TMN). Recommendation M.3013 (02/2000) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunicatio
10、ns. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The 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 Telecommun
11、ication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC
12、 Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication admin
13、istration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or
14、 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, the ITU had not received notice of intellectual property, protected by patents, which may be require
15、d to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2000 All rights reserved.

27、l, information and physical architectures, which are defined as fi-ameworks in Recommendation M.3010, can be used to support the requirements, analysis and design efforts necessary to implement TMN(s). This Recommendation provides guideline information that may be useful for TMN designers, architect
28、s and implementers. Many issues are enumerated that may be taken into consideration for implementing, upgrading or expanding a TMN capability. The design of a physical architecture is based upon logical, functional and information architecture specifications. Since multiple physical architectures ma
29、y meet the requirements of the logical architecture, TMN designerdarchitects should consider the following in order to achieve an optimal physical architecture design to be implemented: o determining access and control points with associated interaction models; maintaining necessary interfaces to no
30、n-TMN systems; considering evolution of interface technologies; o establishing system performance requirements; developing system reliability, availability and survivability requirements; identifymg system administration and other system support requirements. o o o o This Recommendation enumerates a
31、 number of considerations (non-exhaustively) in support of designing a physical architecture. This Recommendation also examines emerging technology directions that may support the business requirements of service providers and may also provide support in meeting the needs of the TMN physical archite

46、tion of a TMN system should consider three important architectures: 1) physical; 2) informational; and 3) functional . These are defined in Recommendation M.3010 and discussed in this Recommendation. The implementation and design of these architectures in a TMN system fulfil business requirements of
47、 an organization. Technologies pertaining to design and implementation should be selected by giving consideration to a business model. Examples of various technologies are presented in this Recommendation. New Recommendations (e.g. functional models and information models) may be developed in the fu
48、ture that support additional business considerations. This clause identifies some architecture aspects that impact the design and implementation of a specific TMN system or component. 6.2 Requirements impacting design and implementation A TMN design and implementation specification should be given w
49、ith the minimum number of requirements that convey the needs of business. In the process of specifymg functional, informational and physical requirements, consideration should be given to (but not limited to) the following: o cost of implementation and life-cycle cost; o selection of a suitable modelling language used to describe requirements, analysis and design. Refer to Recommendation M.3020 for more detailed information; o specimng exposed functionality and information at the reference points that lead to a physical implementation. These specifications should be based on interaction be
