MSTP based on SDH network management system technical specification - Part 5: EMS-NMS interface information model based on IDL/IIOP 1 Scope This part specifies the CORBA IDL-based EMS-NMS interface specification of the SDH-based MSTP. This part is applicable to the EMS-NMS interface of the SDH-based MSTP. This part is not applicable to the management of WDM optical network and PDH system. 2 Normative reference The following normative documents contain provisions which, through reference in this text, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document is applicable to this part. TMF 513 (2003) Multi-technology network management business agreement NML-EML interface Version 3.0 TMF 608 (2003) Multi-technology network management information agreement NML-EML interface Version 3.0 TMF 814 (2003) Multi-technology network management solution set document NML-EML interface Version 3.0 TMF 814A (2003) TM FORUM MTNM implementation statement (IS) template and guidelines NML-EML interface Version 3.0 YD/T 1620.1-2007 SDH-based MSTP network management technical specification - Part 1: Basic principle YD/T 1620.2-2007 SDH-based MSTP network management technical specification - Part 2: NMS function YD/T 1620.3-2007 SDH-based MSTP network management technical specification - Part 3: EMS-NMS interface function YD/T 1620.4-2007 SDH-based MSTP network management technical specification - Part 4: EMS-NMS interface common information model YD/T 1620.6-2007 Technical specification for SDH transport network management - Part 6: EMS-NMS interface information model based on IDL/IIOP 3 Terms, definitions and abbreviations 3.1 Terms and definitions For the purposes of this part, the following terms and definitions apply. 3.1.1 Network Management System NMS of SDH transport network, that is, a software and hardware system used to manage the SDH transport network, which provides an end-to-end network view of the whole network, and is able to manage SDH NEs or SDH subnetworks provided by different device suppliers in the network 3.1.2 Element Management System EMS of SDH transport network, that is, a software and hardware system used to manage one or more SDH NE(s), which manages SDH NEs or SDH subnetworks provided by a single device supplier Note: The EMS given in this part refers to the EMS and SNMS collectively in the traditional sense. 3.2 Abbreviations For the purposes of this part, the following abbreviations apply. CORBA Common Object Request Broker Architecture CTP Connection Termination Point NMS Network Management System TP Termination Point ATM Asynchronous Transport Mode CBR Constant Bit Rate CBS Committed Burst Size CIR Committed Information Rate CoS Class of Service CM Color Mode CF Coupling Flag EBS Excess Burst Size ELL Encapsulation Layer Link EMS Element Management System FD Flow Domain LCAS Link Capacity Adjustment Scheme MSTP Multi-service Transport Platform NE Network Element RPR Resilient Packet Ring SDH Synchronous Digital Hierarchy TD Traffic Descriptor UBR Unspecified Bit Rate VB Virtual Bridge VBR Variable Bit Rate VLAN Virtual LAN SC State Change notification AVC Attribute Value Change notification Best-effort Best-effort, if multiple actions are required in the parameter, perform them if some of them will succeed 4 Interface specification 4.1 SDH common information model The SDH common management interface shall meet those specified in Technical specification for SDH transport network management - Part 6: EMS-NMS interface information model based on IDL/IIOP. 4.2 Description of termination point MSTP termination point, the termination points include ATM termination point, Ethernet termination point and data structures (not defined separately), the definition of terminationPoint::TerminationPoint in Technical specification for SDH transport network management - Part 6: EMS-NMS interface information model based on IDL/IIOP is used. The characteristics of MSTP termination point will be further described in this part. To support the unique parameters of MSTP termination points, it is necessary to add a definition in the transmissionParams of TerminationPoint. For example: {layered=“LR_Fragment”, name=“lcasEnable”, value=“true”/“false”}, the setting of LCAS enabling is achieved through a universal interface for modifying parameters at termination point. layerRate Name Value Notification Remarks LR_Fragment lcasEnable true false SC LCAS enable 4.3 Module pathBinding 4.3.1 PathBinding_T Definition Description Path binding information of termination point. Attribute description globaldefs::NamingAttributes tpName; ——Name of termination point of the bound path. terminationPoint::Directionality_T direction ——The bound path direction (uplink, downlink or bidirectional) of termination point. globaldefs::NamingAttributesList_T allPathList ——Path list bound by NMS configuration. Optional item, keep the list in void state if no content is provided. globaldefs::NamingAttributesList_T usedPathList ——List of paths actually used. globaldefs::NVSList_T additionalInfo ——Additional information, used by the manufacturer when extending attributes, in which case the manufacturer shall give a clear explanation in the relevant technical data. 4.3.2 PathBindinglterator_I Definition
