IN CS-3 management has concentrated mainly up

28、on the management of the SSF. Management of the SCF (see clause 6) provides the functional decomposition needed to develop management requirements and the management information model of an SCF. The methodology used in the definition of the SMF-SSF interface should be used to develop the SCF managem

29、ent requirements and the SCF management information model. The text builds upon Annex UQ.1224, where the foundation for IN management was made. The Management specification is based upon a sub-set of IN CS-3. The methodology for the specification of management for IN FES has been repeated here for c

30、larity. These subclauses consider only stages 1 and 2 of the following methodology. Stage 3 (Information models and Object specifications) can be found in Recommendation Q. 183 1.1. The approach used to provide the specifications for management of the SSF is divided into three steps (see Figure 1):

32、the SSF, SCF, SRF and SDF. In the following subclauses, these steps will be described in more detail. 5 SMF-SSF/CCF Interface 5.1 SSF functional decomposition 5.1.1 Rationale In order to come to the specification of a management information model of an SSF, it should first of all be clear what is to

33、 be managed. Therefore, it is necessary to establish a common understanding of the functionality of an SSF. The basis for such a common understanding can be provided by a functional decomposition of the SSF functionality. This functional decomposition based on the definition of the SSF as given in t

34、he Distributed Functional Model for IN CS-3 in 4.1231. The purpose of the functional decomposition is to: provide the basis for the common understanding of the SSF basic functionality (the target of the management study); modelling; provide a basis for the identification of management requirements a

35、nd management improve the readability of the Recommendation. This functional decomposition could be compared with the computational viewpoint in Open Distributed Processing (ODP). It is more or less in the form of an identification of (computational) objects in he SSF. Note that this functional deco

36、mposition is one of many possible decompositions. It is possible for other SSF functionality to exist, which may impact the management information model. Recommendation 4.1236 (12199) 3 48b259L Ob74802 433 -1 5.1.2 Method The method used to come to the functional decomposition of the SSF contains th

37、e following steps: i .i Analyse SSF functionality Within the Distributed Functional Plane architecture, the SSF and its relationships with other IN-FES are described. Based on this description an initial functional decomposition of the SSF, i.e. a “SSF sub-entities model“, can be made. Analyse and s

38、elect INAP procedures In the Physical Plane specifications, the information flow exchange between the IN-FES is described in detail. Identie which of the operations involve the SSF. Describe DFP scenarios for these operations. Choose a scenario that has not yet been mapped. For the chosen scenario,

39、identis. the required data and functions in the SSF and try to map these to the identified SSF sub-entities. If the mapping can be made, detail and validate the decomposition by considering the detailed operations and parameters in the DFP scenarios. Check also whether specific functionality has alr

40、eady been studied elsewhere, such as charging or routing. If this is the case, try to harmonize/reuse these. If a mapping cannot be made, the functional decomposition should be adapted to allow the mapping. If all identified scenarios have been mapped, and the model appears complete (i.e. all SSF fu

41、nctions and data relevant for management seems to be identified sufficiently well), this model can be used as the basis for the requirements capture. If there are any scenarios left that have to be mapped, repeat steps 1.3 to 11.51. (See Figure 2.) 1.21 1.31 Pick scenario 1.41 Correcextend model 1.5

In order Recommenda

45、tion 4.1236 (12/99) 5 to put these management requirements into perspective, and to check whether they are really required from an operational perspective, they should be related to real (or envisioned) operational requirements. It should be possible to map each operational requirement - at least pa

46、rtly - to operations on the data and functions of the SSF sub-entities. The operational requirements and the management activities that are derived in this sub process are completely arbitrary. These steps are only taken to categorize the management requirements. The only goal is to identifj the res

47、ulting management operations on SSF data. 5.2.2 Method In the process of SSF Management requirements capture, the following terminology is used: e operational requirement: a description of a management process that an IN operator would management Jirnctions: set of management (TMN) operations upon o

48、ne or more data be needing for its business; entities. e In this requirements capture phase, the following steps are identified: a) Identify operational requirements: The operational requirements are the basis for the top-down approach to derive the SSF management requirements. To identifj these ope

49、rational requirements, use can be made of the experience of operational staff in managing IN structured networks; the DFP scenarios identified in step 1.2 can be used as a starting point in this analysis. To fulfil an operational requirement, one or more “management activities“ need to be performed (a many to many containment relationship). The description of the operational requirements and the list of the containing management activities is recorded in an “operational requirement template“. The management activitie
