STD-ITU-T RECMN X-79L-ENGL 297b 48b2571 Ob37b28 T57 FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union

8、(ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes

9、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 Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation X.791 was prepar

10、ed by ITU-T Study Group 7 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 5th of October 1996. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. O I

The p

24、rofile is concerned with general trouble management capability and provides an implementation definition for developers to design their software product to. The profile may be used by network operator personnel to speci the precise trouble management capability required, knowing that product vendor

25、can or has used the definition for product development. iv Recommendation X.791 (10/96) STD.ITU-T RECMN X.79L-ENGL L79b 48b2571 Ob37b32 488 D Recommendation X.791 PROFILE FOR TROUBLE MANAGEMENT FUNCTION FOR ITU-T APPLICATIONS (Geneva, 1996) 1 Scope From time to time all systems, including communicat

26、ions networks, develop problems or malfunctions referred to in this Recommendation as ?troubles?. A ?trouble? in a communications network is a problem that has an adverse effect on the quality of service perceived by network users. When a trouble is detected, possibly as a result of an alarm report,

27、 a trouble report may be entered by a user or the system may raise a report automatically. Management of that trouble report is necessary to ensure that it receives attention and that the trouble is cleared to restore the service to its previous level of capability. At the time of a trouble, a netwo

28、rk may have been interworking with another network to provide a service, and the problem or malfunction may be due to the other network. Therefore it may be necessary to exchange trouble management information between management systems across interfaces which may be client to service provider or se

29、rvice provider to service provider interfaces and may represent inter-jurisdictional as well as intra-jurisdictional boundaries. In addition to exchanging information on trouble that has already been detected, advance information on service inaccessibility may also need to be exchanged. Thus, a serv

30、ice provider may need to inform a customer of future service inaccessibility (because of planned maintenance, for example). The scope of this Recommendation includes all of the above processes for exchange of management information. 1.1 Functionaliy This Recommendation specifies the Trouble Manageme

31、nt functionality for: Reporting of troubles on services or resources on a managed network or system; Tracking the progress of trouble to resolution; Clearing and closure of trouble. In a network environment this encompasses computer networks, data networks and telephony networks. This Recommendation

32、 defines a trouble management model, application services and a number of objects and their attributes that are necessary for trouble management. Requirements for the detection of a trouble, that is to say any cause that may lead to or contribute to a manager perceiving a degradation in the quality

33、of service of one or more network services or one or more network resources being managed, are outside the scope of this Recommendation. 1.2 Field of application In general, trouble management is the trouble reporting and tracking between Conformant Management Entities (CMEs) interoperating cooperat

34、ively towards resolution of a trouble. (No distinction is made between inter-jurisdictional and intra-jurisdictional interfaces.) A trouble report gets instantiated for this purpose. In cases where CMEs are interoperating cooperatively towards the resolution of a trouble, it means that both manager

35、and agent CME may have a shared responsibility for resolution of trouble. The trouble management function Recommendation is one that may be used by a CME acting in: 1) a manager role to manage trouble(s) and any corresponding trouble report(s) that have been raised to an agent role CME for resolutio

36、n; an agent role responsible for resolving trouble(s) and any corresponding trouble report(s) that have been raised to it by a manager role CME; 2) Recommendation X.791 (1 0196) 1 STD.ITU-T RECMN X-771-ENGL L99b = 48b2571 Ob37633 314 m 3) both an agent and manager role to manage trouble(s) and any c

37、orresponding trouble report(s) that have been raised internally (ie. to the part performing the agent role), by another part of itself performing the manager role. In this case, the CME itself is responsible for resolving the trouble, but in addition, the CME may also inform other manager role CMEs

38、that are part of the cooperating networks, if they are liable to be affected by the trouble or can help with trouble resolution. The actual means and methods by which the manager perceives the trouble in the first place and the means and methods employed by the agent for detection and identification

39、 of the trouble are outside the scope of this Recommendation. 2 Normative references The following Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
