6、EoT/MEN) Summary ITU-T Recommendation Q.840.1 covers the management of Ethernet over Transport (EoT) and Metro Ethernet Network (MEN). In this Recommendation, the Element Management System (EMS) is an Operations System (OS) used to manage the individual NEs in a network. One or more systems may be r

7、equired depending on the different supplier products and geographic distribution of the elements in the network. The goal of these systems is to manage elemental layer (NE view) information specific to the network element. The Network Management System (NMS) represents an integrated management OS ac

8、ross the different network technology and EMSs. An NMS communicates with an EMS through the Q Interface to realize its management functions. The functional requirements for the management interface between EoT/MEN EMS and NMS for the integrated management at the network layer and at the element laye

9、r are provided in this Recommendation. Source ITU-T Recommendation Q.840.1 was approved on 16 March 2007 by ITU-T Study Group 4 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. Q.840.1 (03/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations spe

10、cialized 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 telecommunications on

11、 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 laid do

12、wn 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 telecommunication

13、 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 mandatory

14、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 attent

15、ion 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 others

16、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, implementers are cautioned that this may not represent th

17、e latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2008 All rights reserved.

22、cifies the requirements and analysis for the management interface between the Element Management System (EMS) and the Network Management System (NMS) of Metro Ethernet as defined in MEF-10 and Ethernet over Transport (EoT), specifically the Ethernet ETH layer as defined in ITU-T G.8010. This Recomme

23、ndation follows the interface specification methodology described in ITU-T M.3020. In this Recommendation, the EMS is an Operations System (OS) used to manage the individual network elements supporting Metro Ethernet and EoT services as well as the networks between them. One or more EMSs may be depl

24、oyed depending on the different supplier products and geographic distribution of the network elements in the network. The NMS represents an integrated management OS across different technologies and EMSs. The NMS communicates with EMS through the Q Interface to realize its management functions. The

25、management functions covered in this Recommendation include configuration management, performance measurement parameters management, and alarm reporting and testing in fault management. These management functions are described and divided by UML use cases in the requirements. The analysis provides t

26、he managed entities which support a protocol-neutral information model for Metro Ethernet and EoT management, and also explains the static and dynamic relationships between these managed entities using UML class diagrams and sequence diagrams. This Recommendation does not cover all aspects about Eth

27、ernet management; only those related to Metro Ethernet and EoT services management are addressed. This Recommendation is built on and extends the information model provided in MEF 7. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in

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