Introduction of YD/T 1767.3-2009

Technical requirements for automatically switched optical network (ASON) management - Part 3: EMS-NMS interface function 1 Scope This part specifies the interface function requirements related to the control plane management in EMS-NMS interface functions, mainly including the configuration management interface function, alarm management interface function, performance management interface function, and security management interface function. This part is applicable to the EMS-NMS interface of ASON management system. This part does not cover the interface function requirements related to transport plane management in the NMS-EMS interface function. For SDH network, see YD/T 1289.4-2006 Synchronous digital hierarchy (SDH) transport network management system technical specification - Part 4: EMS-NMS interface function for the relevant contents of interface function requirements related to the transport plane management; for OTN network, the interface functional requirements related to transport plane management need to be studied. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part.

Figure 1 ASON management interface functions 4.2 Roles EMS; NMS. 5 Configuration management The use cases for configuration interface functions between the network management system (NMS) and the element management system (EMS) of ASON include MLRA management, MLSNPP management, MLSNPP link management, control channel management, call and connection management, as shown in Figure 2. Figure 2 Configuration management interface functions of ASON 5.1 MLRA management 5.1.1 Get all MLRAs The EMS shall allow the NMS to query information about all MLRAs of the EMS, with request parameters as null. If the query is successful, the information returned is as follows: ——List of MLRA objects. Each MLRA object contains the following attributes: ——MLRA identifier; ——User label; ——Routing area level (values include top-level MLRAs, intermediate-level MLRAs, and routing nodes);
