Fault management architecture

This section describes the fault management architecture.

Polling management data

The MAS supports the polled management model of the Simple Network
Management Protocol (SNMP) to facilitate well-controlled network
management traffic and to enable reliable data synchronization through a
request-response interaction. By maintaining Management Information Base
(MIB) tables and variables, the Internet Protocol (IP) Multimedia System (IMS)
enables the following functions:

To recover the missing data due to lost notifications. This is referred to as
auditing and is described in the next section.

To perform initial data synchronization for the active alarm list.

To monitor the status of operation, administration, and maintenance
(OAM) communications with the agents and resynchronize all data after
recovering from communication loss.
