Processing flow overview

The flow of information among the components of a
and Enablement Pack deployment proceeds as follows.
During discovery:
  • The
    IP Availability Manager
    performs discovery of routers, switches, and hosts, as well as VoIP devices, along with their physical and logical connectivity.
  • The
    IP Availability Manager
    groups the VoIP devices into a Topology Collection using deployment customization. This Topology Collection may be used to filter the devices monitored by
    based on customers’ organizational partitioning.
  • imports the VoIP device information from the
    IP Availability Manager
    , and uses that information as the foundation for its own discovery.
  • uses SNMP discovery probes to discover the VoIP specific elements.
  • After a successful discovery,
    creates a VoIP topology with relationships between the associated elements.
    During event processing:
  • The
    IP Availability Manager
    polls network elements and performs root-cause and impact analysis for the IP domain.
  • The
    IP Availability Manager
    sends notifications to the
    .
  • , in conjunction with the installed Enablement Pack(s), uses SNMP Instrumentation 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.
  • imports the performance oriented data collected by
    to enrich the
    topology with information from traps sent at regular intervals.
  • The
    Global Manager
    receives notifications from the
    IP Availability Manager
    and the
    for presentation to network operations personnel.

    and its Enablement Packs.
