6、ndation ITU-T M.3102 provides a management information model for unified connection-oriented and connectionless networks, based on the unified functional architecture of transport networks specified in Recommendation ITU-T G.800. This model describes information object classes (IOCs) and their prope
7、rties that are generic and useful to describe information exchanged across all interfaces defined in Recommendation ITU-T M.3010, TMN architecture. These generic information object classes are intended to be applicable across different technologies, architecture and services. The information object
8、classes in this Recommendation may be specialized to support the management of various telecommunications networks. This Recommendation follows Recommendation ITU-T M.3020, management interface specification methodology on the analysis phase. The information models provided in this Recommendation ar
9、e in a protocol-neutral manner, and can be mapped to multiple protocol-specific information models (design phase).

10、M.3102 (01/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is res
11、ponsible 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 Assembly (WTSA), which meets every four years, establishes the topics for study by the
12、 ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is 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 collabora
13、tive basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain m
14、andatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements
15、. The use of such words does not suggest that compliance with the Recommendation is required of any party. 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
16、takes no position concerning 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 pr
17、operty, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

21、n-oriented and connectionless networks 1 Scope This Recommendation provides a unified management information model for both connection-oriented and connectionless networks. The information model is based on the unified functional architecture of transport network specified in ITU-T G.800. It is the
22、scope of this Recommendation to define the following: the entities representing the abstraction of resources in unified connection-oriented and connectionless transport networks; the attributes of these entities; and the relationship among these entities, including the entities at the same layer and
23、 at different layers. The above entities are defined in a protocol- and technology-neutral way, which is based on the methodology specified in ITU-T M.3020. But the management interactions are not the purpose of this Recommendation. It is outside the scope of this Recommendation to define the intera
24、ctions across the management interface. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and
25、 other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. Th

33、 Network fragment The network fragment is a grouping of information object classes (IOCs) that represents collections of interconnected telecommunications and management objects (logical or physical) capable of exchanging information. These objects have one or more common characteristics, for exampl
34、e, they may be owned by a single customer or provider, or associated with a specific service network. A network may be nested within another (larger) network, thereby forming a containment relationship. Layer_Network_Domain in this Recommendation can be either connection-oriented or connectionless.

48、ec. ITU-T M.3102 (01/2011) 13 In a connectionless network, a SNw_Ac_Rel_CL can sometimes be represented by a corresponding SNw_Fw_Rel_CL in the largest subnetwork, thus providing a multiple access relationship, as shown in Figure 20.

This is applicable for both connection-oriented layer networks and connectionless networks, which is shown in Figure 21.
