This Recommendation specifies 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 Recommendation 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 deployed 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 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 the 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 Ethernet 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].
