ITU-T RECOMMENDATION M.3300 TMN F INTERFACE REQUIREMENTS Summary This Recommendation provides requirements for

6、 the TMN F interface. The F interface is between a Workstation and other TMN physical blocks: an Operations Systems (OS), Mediation Device (MD), or Network Element (NE). Source ITU-T Recommendation M.3300 was revised by IT-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1

7、procedure on the 26th of June 1998. Recornmendation M.3300 (06/98) i STD.ITU-T RECMN M.3300-ENGL 1998 4862591 Ob52700 OT9 FOREWORD IT (intemational Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The IT Telecommunication Standardization Sector

8、(mr-T) is a permanent organ of the IT. 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 Telecommunication Standardization Conference (WTSC), which meets

9、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 IT-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technolo

10、gy which fall within IT-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 administration and a recognized operating agency. INTELLECTU

11、AL 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 applicability of claimed Intellectual Property Rights,

12、 whether asserted by IT members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the IT had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors

13、 are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O IT 1998 All rights reserved.

37、: o o 0 In figures, the following conventions apply: o o o o Initial capitalization of names is used when introducing terms that are familiar to readers by their acronyms. Uppercase letters (F, Q in “Q3“, and X) identify TMN physical interfaces. Lowercase letters (f. g, q in “q3“ and x) identify TMN

38、 reference points. Open circles represent TMN physical interfaces. Filled circles represent “ reference points. Boxes with labels inside them represent TMN physical blocks. Ovals with labels inside them represent TMN function blocks or functional components. 6 Introduction to the F interface This Re

39、commendation provides requirements for the TMN F interface. The F interface is between a Workstation (WS) and a TMN physical block containing Operations System Functions (OSFs) or Mediation Functions (h4Fs). Operations Systems (OSs), Mediation Devices (MDs), and Network Elements (NEs) may contain OS

40、F or h4F. F interface requirements are independent of which TMN physical block supports them, so this Recommendation will use the term “Operations System“ or “OS“ to refer to OSs, MDs and NEs alike. 6.1 Why Is The F interface needed? Recommendation M.301 O, Principles for a Telecommunications Manage

41、ment Network, introduces the F interface. To enable human operators to interact with the TMN, a Workstation Function (WSF) must be present. When the WSF is implemented on a system physically distinct from an Operations System Function (OSF), those systems communicate via an F interface. The F interf

42、ace is needed: for TMN interactions between a user and an OS; to allow for the interoperability of different systems within a T“, including systems developed by different suppliers; to facilitate work centre re-engineeringkonsolidation that is taking place in the telecommunications industry; to allo

43、w for modular implementation of a TMN: an organization can change and upgrade various modules providing specified functionalities; to support efficient systems integration in a TMN; to allow User Interface (UI) software to be left alone when changes or rearrangements are made to OS functionality; to

44、 allow OS software to be left alone and changes made to i software, taking advantage of advances in i technology; to allow Ui customization for an individual service provider, supporting a common look and feel. Recommendation M.3300 (W8) 7 F interface architecture 7.1 The F interface within the TMN

45、architecture The TMN architecture is defined in Recommendation M.3010. This Recommendation summarizes some of the architecture relevant to the WS and the F interface as an aid to the reader of this Recommendation M.3010 is the authoritative definition of the TMN architecture. Figure 1 illustrates th

46、e relationship between some configurations of workstations and OSs in the physical and functional aspects. Workstation functionality can be distributed (see subclause 7.2, TMN functional architecture and the F interface) as illustrated for the display client and server in Figure 1. ws ws eee WSF eee

47、 “ NOTE - The dotted box represents a “distributed WS“ that supports the WSF with functionality distributed over multiple physical boxes. Figure AW.3300 - Example TMN F interface configurations TMN architecture is defined in three aspects: functional architecture, physical architecture, and informat

48、ion architecture. 7.2 TMN functional architecture and the F interface TMN function blocks provide the TMN with groupings of functions that allow the “ to perform the TMN management functions. Pairs of TMN function blocks that need to exchange management information are separated by reference points.

49、 If the reference points become external, that is, the TMN function blocks are implemented in separate TMN physical blocks, the reference point is implemented as a TMN interface; the f reference point is implemented as an I F interface. The TMN function blocks that exchange information over an f reference point are the Workstation Function (WSF) block and the Operations Systems Function (OSF) block. The f reference point defines the service boundary between the OSF and the WSF. Each function block contains sev
