    10、 ITU-T List of Recommendations. ITU-T RECOMMENDATION G.852.1 MANAGEMENT OF THE TRANSPORT NETWORK - ENTERPRISE VIEWPOINT FOR SIMPLE SUBNETWORK CONNECTION MANAGEMENT Summary This Recommendation contains the enterprise viewpoint specification for managing a transport network from a network viewpoint. I

    11、n particular this Recommendation details the enterprise viewpoint for Subnetwork Connection Management. The specification was written in accordance with G.85 1.1 Management of the Transport Network - Application of the RM-ODP Framework. Source ITU-T Recommendation G.852.1 was prepared by ITU-T Study

    12、 Group 15 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 8th of November 1996. STD-ITU-T RECMN G-852-L-ENGL L99b D 48b257L Ob3b932 233 9 FOREWORD IT (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The

    13、 ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible 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

    14、 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. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolu

    15、tion 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 Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administrati

    16、on and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The IT takes no position concerning the evidence, validity or applica

    17、bility 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, the ITU had/had not received notice of intellectual property, protected by patents, which may be required to

    18、 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.

    24、1996) 1 Scope This Recommendation describes the enterprise viewpoint specification for Simple Subnetwork Connection Management of a transport network. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions

    25、 of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; all users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendation

    26、s and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. - ITU-T Recommendation G.805 (1 995), Generic functional architecture of transport - ITU-T Recommendation G.85 1.1 (1 996), Management of the transport network - networks. Application of

    27、the RM-ODP fiamework. 3 Definitions None. 4 Abbreviations This Recommendation uses the following abbreviations: ITU-T RM-ODP International Telecommunication Union - Telecommunication Standardization Sector Reference Model for Open Distributed Processing 5 Enterprise viewpoint The enterprise specific

    28、ations contained in the annexes were written in accordance with Recommendation G.85 1.1 that defines the FW-ODP methodology employed to generate enterprise specifications in regard to the management of transport networks. The enterprise specifications assume the existence of G.805 network resources

    29、and are thus written from a Network View of managing a transport network, as opposed to network management based upon a Network Element View.
