Optical Transport Manager Architecture
does not show the interaction among the OTM servers and the domains. It does not show theserver or the WDM-NG domain manager.Data flow in Optical Transport Management Suite with WDM-NG domain manager, M&R, and the SolutionPack for Optical Wavelength Services installed
shows the architecture when EMC M&R and the WDM-NG domain manager are installed with the SolutionPack for Optical Wavelength Services. The components of the Optical Transport Management functionality are listed in the Components of the Optical Transport Manager table. Components and functionality are discussed in more detail in the following sections.
Category | Component | Description |
|---|---|---|
for SONET/SDH Topology Server |
| |
for PDH Topology Server |
| |
for WDM Topology Server |
| |
Optical Transport Manager for WDM-NG Server | Receives topology and events collected from TMF 864-compliant VMware systems. Requires installation of the EMC M&R platform , the SolutionPack for Optical Wavelength Services ,and the SolutionPack for Smarts.

for PDH Analysis Server |
| |
for WDM Analysis Server |

The adapters deployed depend on the specific sources of topology and alarm data present in the environment. These can be a combination of element managers, OSSs deployed, and the devices themselves.
Figure 1-2: Data flow in Optical Transport Management Suite with WDM-NG domain manager, EMC M&R, and the SolutionPack for Optical Wavelength Services installed
shows the flow of data when the WDM-NG domain manager is installed. This OTM manager can process events coming from TMF 864-compliant EMS systems by using the EMC M&R platform with two SolutionPacks installed (SolutionPack for Optical Wavelength Services and the SolutionPack for Smarts) Data flows in Optical Transport Managerwith WDM, Sonet/SDH, and PDH
shows the high-level view of the flow of data among the non-WDM-NG components when EMC M&R is not deployed in your network. Data flow inwith WDM-NG domain manager, EMC M&R, and the SolutionPack for Optical Wavelength Services installed.

Data flows inwith WDM, Sonet/SDH, and PDH

There are three types of adapters.
- Inventory Adapters gather topology data from OSSs and/or from network elements.
- Event Adapters gather alarm data from OSSs and/or from network elements.
- Device Adapters (not shown in Data flows inOptical Transport Manager with WDM, Sonet/SDH, and PDH) may supply data directly to one or more of theDomain Manager Topology Servers.OTM uses SDXA (Simple Data Exchange Adaptor) for topology transfer from a Topology Server to the Analysis Server within the same OTM domain.Thefor SONET/SDH shares some topology and alarm data with thefor WDM and the Optical Transport Manager for PDH in order to enable them to perform cross-domain correlation.Information is propagated between Topology Servers of different OTM domains (for example, from a SONET/SDH Topology server to a PDH Topology server) using Remote Accessor Instrumentation to perform cross-domain root-cause analysis.Each Analysis Server sends notifications to the Global Manager, which acts as a consolidation point. The Global Console and other customer operations support systems retrieve notifications from the Global Manager and topology from the Analysis Servers.
