It places ASON management within the TMN context and specifies how the TMN principles may be applied. A m
9、anagement view of the ASON control plane is developed. This view provides the bases for the ASON management requirements specified in this Recommendation. Identifier spaces needed in ASON management are specified. Examples of management system structures and ASON related management applications are
10、contained in the appendices. Source ITU-T Recommendation G.7718/Y.1709 was approved on 13 February 2005 by ITU-T Study Group 15 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. G.7718/Y.1709 (02/2005) FOREWORD The International Telecommunication Union (ITU) is the United Natio
11、ns 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 standardizing telecommunicati
12、ons 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 covered by the procedure l
13、aid 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 indicate both a telecommuni
14、cation administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mand
15、atory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws
16、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 concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or o
17、thers 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 patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not repres
18、ent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2005 All rights reserved.

23、8/Y.1709 (02/2005) 1 ITU-T Recommendation G.7718/Y.1709 Framework for ASON management 1 Scope This Recommendation addresses the management aspects of the ASON control plane and the interactions between the management plane and the ASON control plane. This Recommendation follows the TMN principles sp
24、ecified in ITU-T Rec. M.3010 and the ASON architecture principles specified in ITU-T Rec. G.8080/Y.1304. Included are: 1) identification of reference points and interfaces between the management plane and the control plane; 2) a description of the larger context of ASON network and service managemen
25、t; 3) requirements for the: use of ASON constructs, e.g. routing areas, SNPP links, etc.; management of calls and connections; configuration, fault, performance, accounting and security management for ASON. 2 References The following ITU-T Recommendations and other references contain provisions whic

G.7718/Y.1709 (02/2005) 5.1 Relationship to management information modelling Figure 1 describes the relationship between the scope of this Recommendation and the definition of management information models.

43、e of G.7718/Y.1709 5.2 Relationship to the ASON architecture This Recommendation contains a management framework for ASON control planes as specified in ITU-T Rec. G.8080/Y.1304. The G.8080/Y.1304 reference architecture describes: 1) functional components of the control plane, including abstract int
44、erfaces and primitives; 2) interactions between call controller components; 3) interactions among components during connection setup; 4) functional components that transform the abstract component interfaces into protocols on external interfaces. The G.8080/Y.1304 control plane functional components
45、 manipulate transport network resources in order to set up, maintain, and release calls and connections. Generically, every G.8080/Y.1304 control plane component has a set of special interfaces to allow for monitoring of the component operation, for dynamically setting policies, and for affecting in
46、ternal behaviour. These interfaces are not mandatory and are provided on specific components only where necessary. Components are not assumed to be statically distributed. 5.3 Relationship to technology specific Recommendations The architectural specifications and functional requirements contained i
47、n ITU-T Rec. G.8080/Y.1304 are applicable to any layer network, including SDH transport networks, as defined in ITU-T Rec. G.803, and Optical Transport Networks (OTN), as defined in ITU-T Rec. G.872. 5.4 Relationship to the TMN architecture This Recommendation adheres to the TMN principles specified
48、 in ITU-T Rec. M.3010. ITU-T Rec. M.3010 defines the Logical Layered Architecture concept for organizing management functionality. The logical layers of interest in G.7718/Y.1709 include the Element Management Layer, the Network Management Layer and the Service Management Layer. As noted in ITU-T IT
49、U-T Rec. G.7718/Y.1709 (02/2005) 5 Rec. M.3010, management objects defined for one layer may be used in others. Any management object may be used by any interface that requires it. The Element Management Layer is concerned with the information that is required to manage a Network Element (NE). This refers to the information required to manage the Network Element Function (NEF), the Control Plane Function (CF), and the physical aspects of an NE. The Network Management Layer is concerned with the infor
