Processing
flow
The flow of information among the components of a Enablement Pack deployment is as follows.
During discovery,
information flows as follows:
- TheIP Availability Managerperforms discovery of routers, switches, and hosts, as well as VoIP devices, along with their physical and logical connectivity.
- TheIP Availability Managermay group the VoIP devices into a Topology Collection using deployment customization. This optional Topology Collection may be leveraged to filter the devices monitored by based on customers’ organizational partitioning.
- imports the VoIP device information from theIP Availability Manager, and uses that information as the foundation for its own discovery.
- uses SNMP and SOAP discovery probes to discover the VoIP specific entities: physical elements as well as logical applications like Voicemail Service.
- After a successful discovery, creates a VoIP topology with relationships between the associated elements.During event processing, information flows as follows:
- TheIP Availability Managerpolls network elements and performs root-cause and impact analysis for the IP domain.
- TheIP Availability Managersends notifications to the .
- , in conjunction with the installed Enablement Pack(s), uses SNMP and SOAP to monitor the health of the VoIP topology and generate appropriate symptoms and events.
- includes a built-in SNMP trap receiver which listens for VoIP related traps. Traps generated by the monitored devices and forwarded to the VoIP Availability Manager are processed to set the state of the referenced component. Note that the traps must be enabled and their destinations set.
- At regular intervals, imports the performance-oriented data collected by to enrich the topology.
- TheGlobal Managerreceives notifications from theIP Availability Managerand the for presentation to network operations personnel.The provides detailed information about the architecture of and its Enablement Packs.
