It is important to understand the architectural layout of the OTM Domain Managers and their interactions with other entities in the VMware Smart Assurance OTM solution. These are shown in Data flows in VMware Smart Assurance Optical Transport Manager.
The functions of each OTM domain— SONET/SDH, Low Order SONET/SDH and WDM—are split into Topology/Monitoring server (or simply Topology server) and Analysis server. Currently, each Domain Manager supports a single Topology server and a single Analysis server. All external software entities, such as the adapters shown as gray boxes at the bottom of Data flows in VMware Smart Assurance Optical Transport Manager, interact only with the Topology servers.
