devices and applications, so that an incoming message from a device or application can affect the status of an associated service. Service Navigator provides root cause analysis of service status issues. It can also show the services impacted by a particular failure condition listed in the message browser. When the OV Topology Server is also configured, the service hierarchy can show the specific telecom network element that is causing a service degradation.
OV Telecom Extensions for OV Operations
The primary components of the OV Telecom Extensions for OV Operations product are:
•Telecom subagent—The telecom subagent acts as a data collector to receive messages from telecom network elements and telecom element management systems. The telecom subagent formats the received messages using the configured message source templates. Additionally, the telecom subagent provides table lookup and time arithmetic capabilities. If the OV Topology Server is configured, the telecom subagent formats the messages into X.733 alarm format and forwards them to the topology server for further processing. If the OV Topology Server is not configured, the telecom subagent forwards the messages to the OVO agent.
•Topology adaptor—The topology adaptor forwards problem notifications from the topology server to the OVO agent for inclusion in the message browser. It maps source topology elements to nodes in the OVO GUI node bank for maintaining the two GUIs. The topology adaptor also maintains the synchronization between the message browser and the problems presenter by sending messages directly to the OVO server. This synchronization includes changes to problem ownership, severity, acknowledged state, and discharged state. When Service Navigator is configured, the topology adaptor assigns messages to the applicable services and communicates this information to the OVO server so the status of services that include elements in the telecom topology stays current.
OV Topology Server
The primary components of the OV Topology Server product are:
•Topology server—The topology server receives messages from the telecom subagent and correlates them into problems. The topology
