Source ITU-T Recommendation M.3017 was approved by ITU-T S

7、tudy Group 4 (2001-2004) under the ITU-T Recommendation A.8 procedure on 22 June 2003. ii ITU-T Rec. M.3017 (06/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector

8、 (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 telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every f

9、our 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 laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, t

10、he 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 telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary.

11、 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 mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negat

12、ive 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 attention to the possibility that the practice or implementation of this Recommendation may involve the us

13、e 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 others outside of the Recommendation development process. As of the date of approval of this Recommendation

14、, 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 represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2003 A

18、) 1 ITU-T Recommendation M.3017 Framework for the integrated management of hybrid circuit/packet networks 1 Scope This Recommendation is a part of a series of Recommendations defining the TMN paradigms for management of large-scale carrier networks. It is the scope of this Recommendation to provide

19、an overview of: The evolving telecommunications networks architectures that provide for multi-service networking over packet-switched networks (e.g., IP, ATM, Ethernet). The interworking architectures and scenarios to allow interworking between traditional circuit-switched and Hybrid Circuit/Packet

20、Networks (HCPNs). The services and applications to be provided over the above architectures (e.g., Voice over IP). Management paradigms employed in managing packet-based networks. Considerations for the extension of TMN toward the management of HCPNs. Connections across administrative domains are in

21、cluded in the scope, however, in this Recommendation, no explicit provisions are made for these. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

31、erms: 3.2.1 paradigm: a set of management functionalities that includes a protocol and associated services, as well as a supporting information definition language. It can be used to produce collections of management information including relationships amongst management information to accomplish a

32、given management objective. A paradigm must have mechanisms to support the definition of a library of management information. 3.2.2 Hybrid Circuit/Packet Network (HCPN): a network composed of both circuit-switched and packet-based layer (sub) networks. A packet-based layer may be connection-oriented

33、 or ITU-T Rec. M.3017 (06/2003) 3 connectionless. ITU-T Rec. G.809 distinguishes Connection-Oriented Circuit Switched (CO-CS) networks, Connection-Oriented Packet Switched (CO-PS) networks, and Connectionless Packet Switched (CLPS) networks; and gives details on CLPS networks implemented with IP (us

34、ing best effort, destination-based forwarding) and those implemented with Ethernet. 3.2.3 topology: See A.1.1 for details. 3.2.4 Technology-Specific Network (TSN): a single layer network of the layer-based network model, which is only concerned with one technology, e.g., IP, ATM, SDH or Optical netw

35、ork. 3.2.5 Multi-Technology Networks (MT): For the purpose of providing multiple services, assuring QoS and reducing operating costs, the core networks of service providers are usually composed of several technology-specific communication networks. There are various relations between these networks,

36、 and they may cooperate with each other to provide services. In this Recommendation, core networks composed of several interacting TSNs belonging to the same operator, are called Multi-Technology Networks (MTN). 3.2.6 Integrated Network Management System (INMS): the managing system performing the in

37、tegrated management of MTN. It is responsible for analyzing and processing of the management information collected from TSNs, and the integrated management of topology, configuration, fault and performance of several TSNs. 3.2.7 Technology-Specific Network Management System (TS-NMS): the managing sy

38、stem performing the management of a TSN, including the management of the subnetworks and their relations. TS-NMS provides INMS the management information of topology, configuration, fault and performance of this TSN. 4 Abbreviations This Recommendation uses the following abbreviations: AAA Authentic

M.3017 (06/2003) 5 XML eXtensible Markup Language 5 Overview This Recommendation describes a framework for the integrated management of Hybrid Circuit/Packet Networks (HCPN). It begins in

46、 clause 6, with a description of the network environments in a HCPN that needs to be supported within the integrated management framework. This description includes reference architectures and topologies. Clause 7 describes the Service environment, namely, the relationship between technology-specifi

47、c networks in the HCPN environment. Clause 8 describes the management environment itself. 6 Network environment of HCPN This clause proposes transport network architectures for use as a description of the network environment applicable to integrated management of HCPNs. The focus is on the transport

48、 view of network architectures. Signalling and control architectures are beyond the scope of this version of the Recommendation. Transport services for the control plane are supported by the transport architectures. 6.1 Overview of network environment A set of reference architectures is provided. Th

49、e architectures were developed on the basis of collective architectural input from service providers and are intended to provide the basis for multi-technology network architectures subject to study by the service providers. Each reference architecture captures a grouping of technologies and configurations. The set of architectures exhibit a progression from current technology networks to future networks that will be based on technologies that in
