ITU-T RECOMMENDATION X.170 NETWORK-NETWORK MANAGEMENT ARCHITECTURE FOR DATA NETWORKS Summary The rapid evolution of data transmission service has increased internetwork traffic betw
8、een several types of data networks (e.g. packet switched networks, frame relay networks, ISDN networks and ATM networks), or between public and private data networks. Accordingly, the variety and the volume of management information (e.g. charging or traffic information) of each network have also in
9、creased, and there may be a demand to exchange such management information in a uniform way so that all networks can have access to each other by using a unique protocol or , mechanism. In view of these circumstances, this Recommendation describes the general principles and the framework, for exchan
10、ging management information and management operations between data networks. , Source ITU-T Recommendation X.170 was prepared by IT-T Study Group 7 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 18th of June 1999. Recommendation X.170 (06/99) i - FOREWORD ITU (Internat
11、ional Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (IT-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommend
12、ations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
13、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 technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommenda
14、tion the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PR

Recommendation X.170 NET W ORK-NET WORK MANAGEMENT ARCHITECTURE FOR DATA NETWORKS (Geneva, 1999) 1 Scope This Recommendation is one of a set of Recommendations dealing with Network-Network Manageme
25、nt Interface for data networks, which include: - the definition of the architectural framework to exchange management information for the provision of total Customer Network Management (CNM) services by the carrier accommodating its subscribers; - - - - - conformance requirements. When a carrier pro
26、vides CNM services defined in Recommendation X. 160, there may be requirements to exchange management information or operations with its adjacent network related to its customers internetwork communication. This Recommendation resolves such requirements for the provision of total CNM services for it
27、s customers. It defines the architectural framework for Network-Network Management to exchange management information necessary for a carrier to provide its customers with CNM services related to internetwork communication with another network. This Recommendation makes use of the principles of the
28、CNM and the TMN X-interface. Within these overall frameworks, it meets requirements specific to data networks and the provision of CNM services. the description of services between two networks; the definition of management information elements, such as the managed object (MO); classes, attribute ty
29、pes, action types, notification types; compliance requirements placed on other ITU-T Recommendations definitions; and , 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

48、those customers internetwork communication. Currently, NNM is intended to be used for providing CNM services. That is, the network providing the CNM service collects related management information necessary for the CNM service from another network, and in some cases management action is performed, s
49、uch as line testing. Internetwork communication may range more than two networks. 3.5.2 services and another carriers network involving the customers internetwork communications. 3.5.3 another network for the purpose of CNM service provision. 3.5.4 user with management information or functions required for CNM activities. 3.5.5 provider where management information is transferred. NNM interface: This is an interface between the network of the carrier providing its customers with CNM NNM service user: This means the manager that retrieves CNM
