6、n M.3120 CORBA generic network and network element level information model Summary This Recommendation defines a generic network information model to be used in telecommunications network management based on CORBA. It defines in Interface Definition Language (IDL) a set of generic interfaces and con
7、stants. The intent of this Recommendation is to define a generic CORBA/IDL model similar to that defined in ITU-T X.721 and M.3100 using CMISE. These generic IDL interfaces could be extended by various industries for managing specific network technologies, such as ATM and SONET/SDH. This Recommendat
8、ion includes an electronic attachment containing IDL descriptions.

9、 (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 on them with a view to sta
10、ndardizing 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 of ITU-T Recommendations is
11、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“ is used for conciseness to i
12、ndicate both a telecommunication administration and a recognized operating agency. 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 concer
13、ning the evidence, validity or 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, ITU had not received notice of intellectual property, protected by pat
14、ents, which may be required 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. ITU 2002 All rights reserved.

These interfaces are translated manually fro
37、m a set of M.3100 GDMO managed object classes following the TMN CORBA framework and guidelines given in ITU-T Q.816 and X.780 for fine-grained CORBA interface. In addition to the fine-grained interfaces in 6.5, an accompaning set of Facade interfaces are defined in 6.6. These facade interfaces are d
38、efined according to the coarse-grained extension framework and guidelines given in ITU-T Q.816.1 and X.780.1 for supporting coarse-grained CORBA interface. The name of these facade interface are the name of the corresponding fine-grained interface appended with “_F“ (an underscore followed by a capi
39、tal “F“). In clauses 6.5 and 6.6, the IDL signature of the interfaces are specified in inheritant order, instead of in alphabetical order. The reason of listed in inheritant order is to overcome the limitation of certain “one-pass“ IDL compilers. To facilitate the readability of this Recommendation,
40、 an alphabetical listing of the CORBA interfaces, along with pointers to the clauses and pages at there the interfaces are defined, is provided upfront right after the Table of Contents. The source GDMO definitions used, from which the CORBA interfaces are translated are defined in ITU-T M.3100 and
41、its amendments, except BasicLayerNetworkDomain and BasicSubnetwork, which are defined in ITU-T G.855.1. In most cases, the latest versions of the GDMO managed object classes were used. For example, the Network interface is based on the NetworkR1 GDMO specification. Since in ITU-T M.3100, trailR2 is
42、not a replacement of trailR1, the Trail interface is translated from trailR2 while Trail95 is translated from trailR1. Future alignment between the IDL version and M.3100 GDMO is expected to be maintained as they evolve based on contributions. The behaviour and descriptive text in the comment fields
43、 of the IDL interfaces are taking directly from the source GDMO definition. For the exceptions raised in the operations of the network level resource interfaces, reading of the G.854 series GDMO behaviour statements may be required to understand the semantics of the exceptions. ITU-T Rec. M.3120 (10
44、/2001) 3 The IDL in this Recommendation has been compiled successfully without syntax error. The compiler used claims CORBA 2.3 compliance, which includes value type and M4 macro capabilities. It should be noted that additional interfaces, although required, are not listed above nor shown in the tab
45、les and figures of 5.2. Examples are the factory classes. In addition, other classes are defined in ITU-T Q.816.1, such as factory finder, channel finder, terminator, heartbeat and the MOO service. 5.2 Interface Inheritance and Containment Relationship This clause illustrates the inheritance and con
46、tainment relationship of the CORBA interfaces defined in this Recommendation. The inheritance hierarchy is shown in Table 1, Table 2 and Figure 1. In Table 1, first level subclasses are listed in alphabetical order, while in Table 2, the object classes are grouped according to the fragments similar
47、to those used in ITU-T M.3100. Note that facade interfaces follow the same inheritance hierarachy relationship as the corresponding fine-grained interfaces.
